[Q] Anyone else having WiFi issues with their HTC One?

Hey guys,
So I just got my brand-spanking new HTC One today. I upgraded from the Evo LTE, and I already love it.
But there's one thing that has been really frustrating to me for the few hours I've owned this phone... It has major WiFi issues.
My One can see the WiFi network, can connect to it, but wont give an internet connection! It's so frustrating!
My Evo LTE, being connected to the same WiFi network, connects to the internet with no problem at all.
A temporary fix is to turn off the WiFi radio, then turn it back on. As a result, I would connect to the internet for a minute or so, then it would disconnect from the internet (it's still connected to my WiFi network, and it recognizes it, and it gives no messages about the connection suggesting that something is wrong with my router/connection).
I changed the frequency bands, but they all have the same issue. I have enabled "Best Wi-Fi performance" and "Keep Wi-Fi on during sleep."
I've also reseted my router numerous times... No luck.
Is anyone else having this issue, or did I just get a lemon? Can anyone think of a possible solution?
Thanks!

no issues here with my one and my netgear r6300 ac router.

Wi-Fi has been fantastic for me on my one. My evo LTE if you remember had the issue of wi-fi just shutting off after the phone was asleep. That was fixed in an update but even after that was fixed my evoLTE would show it's connected but data would not work. So I would have to toggle it on & off. I also had an issue with my sense widget not working and getting stuck. I was really starting to dislike the evoLTE because of it since your notifications quit working if your wi-fi was not connected correctly. I put up with crappy wi-fi for almost a year, mainly because I knew if I took it into Sprint they would say everything works perfect I just didn't wanna deal with. I know it's extremely frustrating to not have your wi-fi work correctly. My advice see if you can get a hold of another HTC one to test side by side. If it's a hardware issue you should get it swapped. You could also try hard resetting. I use a a WRT54GL with tomato at home and a Asus N66U at work, both have performed awesome with my one.

I have _exactly_ the same issue with my One. I have no idea if it's a software or a hardware problem. Tried a hard reset just yet, but it didn't seem to make a difference.
Really frustrating indeed, since the One is not very good available in the Netherlands yet, so if I return it, I might have to wait a few weeks to get a new one. I've tried it with at least 6 completely different WiFi networks, but the problem occurs with every one of them.

Only issue I have had with the WiFi thus far is it doesn't seem to have the pickup up range compared to my other phones and tablets.

WiFi on mine is insanely crazy! Picks up signal way better than any other device I've ever owned. Might be the kernel I'm running. Try it out! Look in the original dev thread.

I've noticed this as well. Areas in my office where I could get a decent wifi signal with my 3D I am dropping wifi completely with the One.

Router brand/model? Firmware version? WEP/WPA/Open? 2.4Ghz, 5Ghz or dual band? Channel (more relevant on 2.4 than 5)?
Does your phone get a valid IP? Check on the phone itself then the router under DHCP (assuming normal configuration, IP should begin 192.168.*.*)
Can you ping any internal node (ie your router) or external node (ie google.com or the IP to google)?
If your router has WEP/WPA enabled, switch it to Open solely for testing the connection.

Had the exact same problem. Only thing that fixed it was switching my router encryption from WPA to WEP. Works like a charm now. Best of luck.

Same problem and my solution
I had the same problem. Finally I tried to reset the phone without putting all my google-account info back. Then the wifi works fine. After that a Added my google-account and can enjoy my new HTC one. The phone is really good!
Note that in this way I didn't get all my setting back from my google account (like access points), but at it is working!

Wifi Issues?

Is anyone else having an issue where your device will be hooked up to a wifi network, will still indicate you're connected but no data will sync? I email myself and nothing happens. Happens with FB, Email, Gmail, and Voice Controls don't work.

I have that issue with my gNex and my wife's DNA on our home network. I don't think it is necessarily this phone, but I am not convinced (yet) that it is my router, either...

It comes and goes, it looks almost app specific. I say Hello Google Now, and it seems to lock up on recognition or says it can't connect to google....but I'm able to browse the internet.

Yeah I've been having a ton of WiFi issues with this phone.

I called Moto and after dealing with their terrible level 1 support I got the following:
HERE ARE THE INSTRUCTIONS FOR DOING THE WIPE CACHE PARTITION:
This will remove any temporary files that may be causing the problem, but will not delete your files or settings.
1. With the phone powered off, press the VOL DOWN KEY for 2-3 seconds then POWER key then release.
2. The device will display different BOOT OPTIONS
3. Use the VOL DOWN Key to SCROLL to Recovery and VOL UP Key to select
Tip: If the device reboots, you may have waited to long to make a selection, you will need to begin the process again.
4. The device will display the Motorola logo and then the Android in distress ( logo with Exclamation mark)
5. Press and hold the VOL UP key for 10-15 seconds. While still holding the VOL UP key tap and release the POWER key
Tip: You can try this step, holding the phone in landscape. If you are stuck on step 6, try a force reboot by pressing the Power key and Vol Down key, and start the process again.
6. The device will display additional menu options (Text will appear in BLUE)
7. Use the VOL DOWN Key to scroll to wipe cache partition and the POWER Key to select this option
8. The device will then perform the partition wipe
9. The device will reboot and start the normal power up sequence
Ever since it hasn't had any problems, but it's only been a few hours as well.

The issues started happening again...turned off wifi and everything resynced perfectly...

If it doesn't work properly with a different router try exchanging it. Also have you gone into advanced WiFi settings and forced the moto x to 2.4 GHz? If give that a try.

The force to 2.4ghz actually made the problem occur a lot faster, any reason it might be due to the massive amount of wifi networks around? When I set to scan 5 ghz there was only one still open, I might go into my router and see if I can change the atenna settings.
EDIT: Turns out if I go to 5 ghz my computer can't connect, but I changed the channel to something less populated in the area to see if that helps.
DOUBLE EDIT: It appears to occur after I'm supposed to get a Facebook notification, at that point I don't get any more notifications....attempting to clear out facebook data and cache to see if that does anything

Try disabling WMM on your router.

Forgive the stupid, but what's WMM short for in case that's not readily apparent?
Edit: I've also noticed the problem is exponentially worse after I upload pictures to facebook
Edit Edit: Found WMM, turned it off, let's see what happens.

I has this kind of issue before and did a cold boot but nothing happaned. so my last option was to do a restore. After that, my WIFI connection got okay again. problem solved :silly:

You mean full reset? It looks like I may have to do that with the idle battery drain issue anyways....so that's the last resort.

Hey guys I'm having a similar issue with my moto x on the 2.4ghz band. Speeds are very slow and sometimes cut out completely. Im getting a download speed of about 300kb/s on 2.4 both on auto channel and it doesn't rlly change once I change it manually to an open channel using WiFi analyzer app. My download speeds on 5ghz hit 4000kb/s even with a much lower signal strength.
YouTube and Netflix is unusable and growing the internet sucks. I usually just use the 4g network while at home cuz its a thousand times faster but I'd like this to be fixed regardless. Has anyone found a solution or explanation?

I'm having these issues too. Got the GSM Developer Edition on 11/29. It immediately updated to Kit Kat OTA so I'm not sure whether it had the issue prior to Kit Kat or not. This only happens on 2.4 ghz wifi and only with one of my routers at home, a Netgear WNDR3700v2 running OpenWrt Attitude Adjustment (I tried upgrading from Backfire to see if it would help, it did not). The other router is a Linksys WRT350N and when the phone is connected to that one the problem does not happen. Note, that there are 2 laptops, a Samsung Galaxy S2, and a Kindle Fire HDX that have zero problems with the WNDR3700. All can transfer data perfectly fine and at high speeds. Thus I do not think the router is bad. Have not checked work routers. 5 ghz wifi is totally fine and indeed very good with this phone.
For me, the problem is that the phone seems unable to receive data at high speed (over 1Mbps) on 2.4 ghz wifi in any area where the signal isn't perfect and sometimes even in the same room as the router (although usually it is fine there). Oddly in many cases when it has trouble receiving it can send data much faster. It almost seems like it might be some kind of interference as it is rather random.
At this point I'm wondering if the phone has a defective 2.4ghz subsystem, though that seem unlikely due to good transfer with the WRT350N, or if this is some kind of wifi tuning software bug in the phone.
Any info would be appreciated. Does anyone have this issue who did not have the issue on Jellybean? Am wondering if anything changed with wifi for the update? Note, I have tried clearing the cache in recovery as noted in another thread with no luck. Anyone have the WCNSS_qcom_cfg.ini file from Jellybean for this phone? Would rather not reflash just for 1 file.
Thanks.

For what it's worth I have this same Netgear router and have had the same connectivity issues on both 4.2.2 and 4.4.
I did some reading today and found a couple possible fixes I plan on trying out. First one is to disable WMM. Secondly I found on the official netgear forums that they have had major issues (some of which you've described) with all firmwares ending in the .30s and went so far as to pull them from their download section.
My router was running firmware .36 and I successfully downgraded it to the latest stable firmware .12 that netgear now recommends.
Hopefully 1 of those 2 fixes improves the performance, at any rate I really think it's something with the router itself and not the moto x.

Thanks for letting me know this was also an issue on 4.2.2. Saves me the trouble of flashing back just to test.
I will be interested to know if your using official netgear 1.0.0.12 firmware fixes the issue for you. I haven't actually ever used the official firmware as I've run OpenWRT since I got the router a year or two ago. 10.03.1 had the issue, and it appears 12.09 does as well. I may try a trunk build at some point to see if that changes anything.
I had previously written that all was well on the 5 ghz band. This appears to not be 100% correct. Yesterday evening and this morning I found myself "connected" to the 5ghz band without actually having working internet. Toggle wifi on/off fixes it, but I shouldn't have to do it.
Not sure if this helps, but on the 2.4 ghz side things do work better on one side of the house vs the other. Also it seems that I can get a very fast connection at times and then it stumbles and gets stuck going under 1 Mbps. I still suspect either a defect or some kind of low level radio issues with the moto or the router regarding interference from neighboring wifi access points (there are a lot around me, single family houses on small lots). However, keep in mind no other device has these issues but the moto. In the rare instance I venture into a bad signal pocket the signal indicator goes down and speed slows or they lose connection vs the moto where it can show excellent signal and have no/nearly no connectivity.
I haven't tried it for long, but switching to wireless g mode vs ng may improve stability though I only briefly tried it. I did walk around part of my house checking the Mbps with the app "WiFi Speed Test" and while way slower than N mode it was far more stable. Even if this does work it is a definate downgrade in speed though.

Well its only been a day or two so it may be too early to tell, but so far my wifi seems much better after making those two fixes I mentioned above. This is on 2.4 band, the 5ghz band doesn't provide me enough signal strength to use all the time (router is too far from my bedroom).
The main issue I was having was my wifi signal would cut out even though it still showed a good connection. I could swipe down on the status bar and see no download arrow next to the wifi icon so I knew I wasn't receiving data. However a simple disconnect and reconnect to my wifi would fix the problem until it happened again. This seemed to be most common while watching YouTube videos, in fact it happened far too often which is why I went searching for a solution.
So as I mentioned things seem to be better for sure so far but I need to give it a week or so to see how much it is really helped, but so far I can't remember any wifi cutting out since I've made those two fixes.

HTC ONE 5ghz problem.

Hi all,
I was wondering if anyone have had issues with the phone not showing any wifi 5ghz bands?
My phone is not showing or connecting to these networks and am just wondering why? I've tryed changing the auto to 5 no luck, I've wiped the device, rebooting and have tryied chaing the channels with no luck.
My device is running ARHD22 which is 4.3 and my router is a cisco EA4500. Annoying thing is that the iPhones and laptops are picking it up. I've even changed the SID for this band to check if I could see it but the phone will only show and connect to the 2.4ghz band.
Thanks

HTC One Dual-SIM 5Ghz WiFi Problems
Hello,
I'm having the same issue - brand new HTC One Dual SIM running Android 4.2.2.
Will display and connect to all 2.4Ghz networks perfectly, but anything 5Ghz it won't even detect, or connect if I add them manually to the saved settings list - tried it with all the 8 APs at work and my two Ubiquiti UniFi APs (Pro & Outdoor 5G) at home and no luck.
Being a work phone they've said we've got to send it back to the supplier rather than to HTC, but this is the second phone I've had with exactly the same problem.
Called up HTC and after about an hour of troubleshooting everything involved until they believed me, they said there wasn't anything they could think of - but it's a little weird for two to have the same problem right out of the box!
Apart from hard reset, wipe cache partition and safe mode - anything else anyone can suggest could fix it?
Regards,
iamacarpetlicker

Sorry, yes ARHD 53 isn't compatible with dual-SIM. But my Single SIM even on stock unrooted could easily pick up 5GHz bands

Please edit your post!!
ARHD 53.0 is not compatible with Dual-SIM HTC One M7

Just an update on the issue if anyone is having the same problems.
We had our 4th Dual SIM handset delivered today (from a completely different supplier and production batch) which still had the same issue, unable to locate 5Ghz networks and unable to even attempt to connect to them.
We also noticed during debugging that if you switch to 5Ghz only in the menu and go back, it'll be unable to find any networks, but if you then turn the WiFi off and on again, it'll then show you a random selection of 2.4Ghz networks, even though the radio should be in 5Ghz only mode.
Because these are company owned devices to be used as work phones, we can't use custom ROMs.
I've been on the phone with HTC a lot today and after finding the support desk were no help, the comany I work for got me in touch with the Corporate Sales Manager over there and we had a conference call with their tech team.
They said it appears to be a software fault affecting all handsets of this model, but are unable to confirm if it is with all 5Ghz access points (we've only tested with Ubiquiti and Apple APs) as they seem to think it works for them in the lab.
We are getting shipped two debug handsets on Monday, one running 4.2.2 they have tested in their lab and one with the latest official 4.4 ROM that they said is due for release next week, to test before release to see if it resolves the issue.
Will post the results hopefully on Tuesday.

try with 5 characters or less.

Thanks for the reply nkk71.
Doing that along with renaming the Bluetooth too then rebooting the device was one of their debugging steps on the phone earlier, but still no joy .. Appreciate the suggestion though!

how about changing channel number?

Yes they suggested it could be something to do with the channel, but so far we've tested:
Indoor at work (Ubiquiti UniFi Pro): 140
Indoor at home (Ubiquiti UniFi Pro): 136
Outdoor at home (Ubiquiti UniFi Outdoor 5G): 128
Test Network at Home (Apple AirPort Extreme): 100
Which according to goo.gl/azMC91 are all in Band B of the 5Ghz spectrum and require DFS compliance.
But the strange thing being, my personal HTC One X connects to all the networks perfectly fine - and in the case of the work APs, we've got ~40 other devices connected on 5Ghz as we use it exclusively, half of those being Android phones, so I guess if it doesn't support those channels, that's kind of a bug in itself?

How about non-dual-sim HTCs?
PS: i'm just throwing ideas out.... nothing concrete !! (otherwise i would have said so)

That's ok, help greatly appreciated.
Like I said, my One X works great on those networks - as for a more similar matched HTC One (non-dual-sim), I know our Directors all had them when they first came out and they definitely worked as we've been using 5Ghz exclusively on those APs for some time now and I'd have had a lot of ear ache if they didn't, but I haven't seen them using them in a long time and they could possibly have been pre-release handsets given as gifts if that could make any difference, so couldn't confirm for the latest firmware updates / model revisions.. I'll have to see if our returns department has one I can borrow on Monday to test and confirm.
I'm hoping it is just a software thing and the 4.4 ROM they're shipping us to test next week will fix, as I read a few posts that the HTC One did originally have a few problems with 5Ghz when that was on 4.2.2, fixed by an upgrade to 4.3 which obviously never made it to the Dual SIM.. It was a little hard to tell from the post descriptions if the problem was indeed the same or not.

Hello,
We've been having internet troubles so I couldn't post the update on Monday, but good news.
Got in on Monday to a message from HTC - they decided over the weekend that rather than shipping me the debug phones to test, they had released the 4.4 OTA update that morning to everybody with a Dual-SIM handset and to just try updating it.
I asked them if they could test it their end before shipping the handsets out to me, so I can only assume they realised it was a problem - or they were just ready with the update - who am I to speculate.
Installed the update and the 5Ghz WiFi now works perfectly - shows up in the list and connects as expected with speeds that are stunning!
Seeing as all phones still come with 4.2.2 out of the box, you'll either need working 2.4Ghz WiFi to download the update (which was hard for us) or support did send me a link to a Windows based updater program to update the phone via USB. They said I'm not allowed to share, but I guess they'd provide it if you called up and asked for it.

You say your phone connects on the 5GHz network, but have you seen if it's connecting on the 802.11N or the 802.11AC network?
My ONE will connect on the N network on 5GHz, but not the AC network.
I've tried Auto channel selection and manually assigning channels, still no go with the AC network.

Hello,
We've been having internet troubles so I couldn't post the update on Monday, but good news.
Got in on Monday to a message from HTC - they decided over the weekend that rather than shipping me the debug phones to test, they had released the 4.4 OTA update that morning to everybody with a Dual-SIM handset and to just try updating it.
I asked them if they could test it their end before shipping the handsets out to me, so I can only assume they realised it was a problem - or they were just ready with the update - who am I to speculate.
Installed the update and the 5Ghz WiFi now works perfectly - shows up in the list and connects as expected with speeds that are stunning!
Seeing as all phones still come with 4.2.2 out of the box, you'll either need working 2.4Ghz WiFi to download the update (which was hard for us) or support did send me a link to a Windows based updater program to update the phone via USB. They said I'm not allowed to share, but I guess they'd provide it if you called up and asked for it.

I found that on the ac network the htc one m8 will only connect when signal is broadcast on channels 32 26 or 40.
Try it out and see if you have any success

[Help] Wifi issues when going from one router to another

I'm having wifi issues.. When I use my office wireless and then come home and use my wifi... it shows I'm connected but there is no data is being sent or received. I'll restart the wifi, phone and router - nothing works?
At the office, I have a 4 year old Netgear Wireless-G router (works on B and G).... At home, I have a 1yr old Apple Air Extreme dual band router that works on B, G and N. Nothing else has any issues. I take a laptop several days a week and it connects fine to both the office and home wifi.
It has gotten so bad that I sometimes have to restore from a Nandroid or reflash my ROM just to connect at home.
It's not a ROM issue, I've had this problem on 5 different ROMs (3 Sense and 2 GPE). It's not a firmware issue, I flashed every firmware known to the HTC One in the past 2 months. It's not a Radio issue, I've flashed every radio available too and still have the issue.
Today, on my HTC, I went in to the advanced wireless settings and tried several things and then unchecked every box that was checked and re-checked them and kept restarting the phones wifi each time. It finally started working, but now I'm not sure what step got it working?
It'll probably be fine for a few days, then I'll loose it at home again.... But it's always fine at work?
Any thoughts? Is this Apples way of saying "You should have an iPhone"?

I am seeing approximately same issue over here: while I am mostly using mobile data at work, at home am on my 3rd router in as many years, just replaced an old linksys wrt600n for a netgear r6100. I would occasionally experience your problem, usually on the 5ghz network, would switch to 2.4 and then back to 5. that works all the time. there are so many variables with wi-fi connectivity, it is really difficult to investigate and diagnose. I cannot tell for sure but I think the issue is on our HTC One device side as my old ipad never dropped the 5ghz connection. I, too, tried all radio firmwares to date with same outcome.
one advice that seems to help here, under advanced wifi settings, disable the battery optimization check.

I did have the Wi-fi optimization checked.... It is now unchecked.
Thanks for the advice!

Dodgy wifi

Has anybody had any problems with their WiFi not connecting? My device seems to fail to connect to wifi after a couple of days and just sits trying to connect. Toggling WiFi doesn't seem to resolve it, and I have to reboot the entire phone to get it back online.

No problem here.
Connects very quickly, never seen it fail to connect, even on my works dodgy BT homehub 3, which used to tie my old Z3 compact up in knots..

Yep.I thought that Snapdragon 835 cause this problem. Xi oami 6., ZTE z17 and Op5 had the same question with WI-FI connection.

I have a sd835 s8 and I haven't had any wifi issues whatsoever since launch. It's a sample size of 1, but I don't know if it's truly due to the sd835

I haven't had any WiFi issues. In fact my WiFi connections have improved using the XZ1 compact over the X performance (the X performance dropped its WiFi connections 3 times during my data transfer to the new phone)

I've had my XZ1c for about a week now (European model) and it connects to my home network (5G) normally. Signal strength is fine, although the galaxyS6 it replaced definitely had superior reception. I do have wifi issues, but only when already connected to the network. When the phone is asleep (screenlocked) it seems to lose an active connection. The wifi connection should be on at all times, even asleep. It will show the wifi symbol, but data apps don't load, and it will have lost the connection as remote for spotify connect (playing on my reciever). It will also switch to mobile data at random times with normal wifi signal strength (even though I toggled this function off in the developper settings).
I'm not sure if this is something that can be fixed through system updates. I haven't seen any forum posts with similar problems though, so I'll try to document what is actually happening before I contact Sony support.

I bought the US version and flashed the UK firmware to get the fingerprint reader to work. No issues whatsoever with this phone. No Wi-Fi issues, overheating, signal strength, battery, nothing. Everything works just perfectly.

Same issue here. Mine is Europe (NL) version. The upload and download speed can be very unstable. And especially when I take it a bit far way, even you see that it's connect to the wifi with full signal strength, it said internet is unavailable.
I'm not sure if this related to the system update of last weekend or not.

Further to my issue. My phone will drop wifi connection and repeatedly try and connect - it usually cannot see any other networks at the time. Restarting the wifi on the phone, or rebooting the access point do not help. Running a packet sniffer on the LAN shows no activity, which indicates the issue is to do with wireless handshaking.
The problem occurs every few days and the only way to resolve it is to reboot the phone, which fixes it instantly.
I contacted Sony and they told me to do a complete reset on the phone, this didn't work. I updated my findings and pointed out that it's seems to be a firmware compatibility issue. Of course, you only get to talk to first line, and as a reset didn't work, they want me to send it off for a warranty repair (which of course will be returned with "no fault found" as no doubt their wifi will be different enough for it not to have been picked up on day 1 testing).
I'm currently trying to gather a bit more information on the fault, e.g. does it only happen on my home wifi etc. I've disabled channel bonding but that didn't help, and I've not jiggled my DHCP settings after seeing plenty of posts describing wifi problems on Oreo for other phones.
It doesn't happen frequently enough and I don't have the time to delve deeply into the network to identify the cause.
One interesting thing was that it went funny at home, but it was working when I got to work. When I got home it still couldn't connect. So I suspect it's to do with a particular compatibility issue somewhere.

no problem here conecting to 5 and 2.4 wifis...

I haven't gotten around to this yet. Do you still have wifi calling and volte available?

So far my wifi has been fine...

Mine is worst, i couldnt get it to connect at all but all my other device including xperia xa, xzp, laptop, Ps4 PS3, everything connect without any issue whatsoever, already excahnged once and still the same.

Think mine is struggling with either a single access point or VLANs. I need to dig further, but that requires buying a new AP - this phone is getting more and more expensive!

exactly same issue as Dashers describes with my XZ1c. I am not watching it closely, but it seems that it is hapenning after around 2 days online. Never happened before on same network with my previous Z3c, which had run months without restart and any problems whatsoever (till its display died

I have more or less the same issues, and a reboot always solves it. It happens with both routers form ASUS and Draytek.
Additionally I see issues with Spotify connect dropping or not being found on my Sonos (hardwired to LAN), but not so much to Chrome Cast Audio on the same network.

I don't have a problem connecting to wifi, but I seem to have a different issue. Even though wifi scanning is toggled off in settings, my phone still seems to be scanning according to Battery Historian. I think this is one of several things contributing to my high idle drain. Does anyone else have this problem?

Have you turned wifi scanning off ?
settings\Lock screen & security\Location\Scanning - turn wifi scanning off

Yes, wifi and BT scanning are both turned off in settings and have been since the beginning, but both seem to be happening anyway according to Google's Battery Historian tool. When I go back in to see if they've been toggled on by an app or something, they still appear to be off.

I have this exact problem. One second its 100% signal and is workin as expected. The other second it just drops and tries to reconnect like crazy. I have even had moments when i am unable to find my wifi after said disconnect. All my other devices is working like normal on my wifi. Using Asus n66u 5ghz.

I have been having the same issues as mentioned above with my XZ1 compact(european). My issues with dropping wifi signal seems to be happening when there are two different wifi signals to choose from. They are both on my local network. One is an extender due to the size of my house. When it can detect both signals, it can't make a decision on which one to choose. Once I remove a device(forget wifi device), it stays connected to the other with no problem. Since it isn't trying to compete with the other.
Has there been any improvement on this issue?
