Huawei P9 - Wi-fi issue (randomly dropping off) - Huawei P9 Questions & Answers

I experience this problem since I have the phone: The P9 Wi-fi randomly disconnects and then reconnects immediately (it can happen 5-15 times during one hour).
This is very inconvenient during large files transfers or when playing games that require a steady connection.
I have tried the following actions without any success (my router and phone firmwares are up to date):
- delete and re-add the Wi-fi network
- turn everything else off (e.g. Bluetooth, NFC)
- disable/enable "Wi-fi+"
- apply all different settings of "Keep Wi-fi on during sleep"
- disable Bluetooth / Wi-fi scanning under "location"
- P9 and router reboots
- force the connection only to the 2.4 Ghz / 5 Ghz router's network (with or without separate SSID),
- change the Wi-fi channels (to avoid congested Wi-fi channels)
- disable IPV6 on my router
- disable DHCP and connect with a fixed IP
- reset the network settings on the P9
- factory reset of the router and phone (what a waste of time...)
Meanwhile, Wi-fi is working perfectly on my Samsung Galaxy S6 Edge Plus and iPad.
Does anyone else experience Wi-fi issues with the P9 ?

I can only report that I have 0 issues so far, my wifi reception is strong and constant,even better than on my tablet.

Mine too perfect no issues.

Thanks for the feedbacks! After further digging, it appears that some marshmallow devices don't work flawlessly with IPV6 (at least with my router).
I saw afterwards exactly the same issue when a Moto E 2 connected to my wifi network.
I already disabled IPV6 on my router without success. I tried again and after changing this setup, I made sure to remove all connections ("forget the network") and reboot everything before reconnecting. It worked!
So it was actually a combination of the steps I previously mentioned that fixed my issue.

I'm getting a lot of disconnects, where the phone switches to a 2.4GHz connection or to mobile data but in my case it's an issue with the router - and I'm trying to work out if there are any settings that cause problems (it's an Asus DSL-AC68U with the latest software).
The phone itself seems to have excellent Wi-Fi and mobile connections, suggesting very good antenna design. But most Huawei made phones have good antenna design. My P8, despite being 2.4GHz only, was excellent for Wi-Fi. My Honor 7 also seems to be exceptional, as is the Nexus 6P.
Does make it hard to use another phone.

I am also having dropping WIFI problem. But it only happens when I am on 5ghz and when I am two rooms away from my router. I have a Asus RT-AC87U.

Mine use to disconnect too and I changed router to 20hz from 40hz under WiFi

I was at a telecom shop today and inside the shop they had wifi. Of all the wifi connected smartphones on Display the Huawei 8 and Huwaei P9 Plus had the best wifi connections with the strongest reception showing full bars while other smartphones were showing 2-3 bars for wifi connection reception

@desiregeek : Huawei 8, you mean Mate 8, P8 ?! I'm glad to hear that triple antenna implementation is one real upgrade , not just marketing ☺

Where did you hear that?

From Italian and spanish reviewers on YouTube (all of them said P9/plus is great for Wi-Fi and cellular signal), you just confirmed. I tested myself briefly in store and Wi-Fi range is a bit better than my Mate7 which is is very good for Wi-Fi signal strength reception.

Yes, it is my second post. The issue was with IPV6.

Bad experience with P9.
1. Ear speakers not good
2. WiFi catcher was very poor.
3. Keypad font not satisfaction.
4. Screen size should be wide.

Hi, Im having the same problem with my huawei p9.
Hi, Im having the same problem with my huawei p9. I thought the problem would be in my router but my laptop is working perfectly fine, but my p9 connects and disconnects frequently and disrupts my work.
Can you say again how you did with your p9 to fix the issue?
Looking forward to your positive response. thank you.

Hi, I don't know exactly what step solved the issue. I actually did everything in the post you quoted and then eventually clicked forget network on the phone. It worked afterwards.

Home Wifi Issue

I have noticed lately that my Moto X will sometimes not connect to my home WiFi. At all. Until I reboot the phone. Toggling WiFi on and off, and forgetting the network do nothing. Other devices (other phones, computers, tablets, TV, etc) are all connected fine, but won't connect. It can see the network, but that's it.
It's only my Moto X and only my home WiFi. It only happens once or twice a week, but it is annoying to have to reboot.
Mostly unrelated, but my Bluetooth icon doesn't always change state. I've noticed that sometimes even hours after getting out of my car the Bluetooth icon is white instead of dim gray like it should be when not connected. That doesn't seem to have any bearing on the ability to connect, just something I've noticed. Usually toggling BT off and on again fixes the issue.
Phone is a rooted 4.4 Verizon Moto Maker edition. I do have SnapDragon Battery Guru installed but I never set anything up to save power. There is a setting in stock WiFi settings about consuming less power on WiFi, but that would seemingly impact all networks, not just home, and it would only be in play once I am connected to the network, not before.
I do use Tasker to enable my WiFi when I get near home (based on cell towers when and I'm NOT connected to BT in my car), so WiFi typically shuts off when I leave home, turns on when I get to work (based on calendar events), turns off when work is done (calendar) and then turns on when I exit my car (BT disconnects and I'm connected to one of a few nearby towers). Only seems to happen when I get home from work, so it could be something in Tasker not properly enabling WiFi? If I notice it again I will try to connect to another different network before rebooting, if there any unsecured networks nearby at the time.
Thanks for any advice.
FYI... I use Tasker almost twice a day to shutdown wifi and turn on bluetooth (among other things) and have never had an issue connecting to any wifi. Not saying that is not a possibility in your case but it certainly hasn't been my experience.

Thanks. I don't think it's Tasker, I've used it for years and never had any issues either.
I used screen record in Gravity Box to show what it does when I try to connect. It did what I described above upon arriving home from work today.
https://copy.com/fU1Gork0RZZmkXA
I tried connecting to my home network and then an xfinity network that uses a Web login or whatever to authenticate after connecting. Neither would work.
It would show full strength until I tap connect and then it goes to the lowest signal and does nothing.
Rebooting now, I guess.
I have the same problem. Some other user advised me to configure my router as "G only" and it has worked.

Thanks. I've had some other issues with my router lately too, so I did a factory reset yesterday afternoon. There were some plaguing speed and latency issues on wifi only. I learned that the smart TV while plugged in to ethernet, was still setup to use wifi. I don't know the spec on the wifi adapter in it, but I changed it to ethernet to see if the link speed for wifi devices would go up. It did jump from 24Mbps to 65Mbps, but still felt sluggish.
I will monitor it this week and see if it still has issues connecting. I don't want to limit to the G speeds, as everything that uses the wifi is N, I believe. There are three of us, all with new phones (2 Moto X and an S4), and one laptop that is used often, but it was bought in late 2013, so it (probably) has an N card.
I enjoy the battery life that wifi allows, but can't stand the 200-400KB/s speeds it seems to be offering. It has to be something with my home wifi, because when I'm on my wifi at work (fiber line) and load gifs from reddit they hit 2-3MB/s according to my network monitor.
If you have a dual band router.... connect to the 5ghz frequency.... that worked better for me. The 2.4ghz had a better range, but kept getting page errors or disconnects

Galaxy Note 5 N920W8- Wifi Cuts In And Out

Wicked wakelocks and WiFi issues
Just yesterday I started having wicked WiFi issues, where both 5GHz and 2.4GHz networks would connect, then immediately disconnect, then connect again a few seconds later for it to just do the same thing, over and over. It keeps sending reports everytime it does it. I haven't factory reset though, but I'm going to have to.
Also, I keep getting insane wakelocks. Android OS is the worst, causing 7h+ of wakelocks in a 10h day. Google Play Services is pretty bad too, around 6h+ in that same 10h day.
Anyone else having major issues like this with their Note5? I have the N920W8 model, which I can't really find any info about anywhere
Im having similar wifi issues. Initially trying to connect to my 5ghz N home network (wpa2 psk) connect attempt, drop, connect attempt drop rinse and repeat. After a while it connects and stays connected, however, connecting to any web pages is painfully slow (like a super slow dns lookup), and i frequently get failed web page loading errors or failed to download apps from teh app store. Wifi calling is useless in this state. The same thing happens on an open hotspot network at work (2.4ghz) and the corporate (5ghz n) network. The note will ususally eventually drop wireless and force me back onto LTE. I looked at my data counter after just 3 days, and had used 27gigs of LTE, which is more data than I've used on tmobiles network since last year. Had some spotty wireless issues with teh note 4 rev 3 5.1.1 as well prior, but only had that phone for about 10 days before swapping for teh note 5. Prior to that I had the nexus 6 and no wireless issues on the same networks.
J'ai le même problème avec le 5g damn!!!
Luckily i have a dual dualband router, I set up the alternate AP 2.4ghz N wpa2 psk and the phone appears to be working fine at the moment on that network.
I ended up factory resetting and it appears working for now. A static IP address (DHCP reserved in the router) seemed to help.
Another issue I have though is when disconnecting from WiFi and connecting to mobile data, it seems to have DNS resolution issues until I turn data off and then back on. Not sure if it's the phone or the carrier (Wind Mobile) but it's pretty consistent
Not seeing these issues on my W8.

I'm just having dreadfully slow WiFi on my att model, but it doesn't drop connection
Dial *#0011# and click "wifi settings" from the menu at the top right corner. Turn off power saving mode and restart the phone, see if that does the trick.
If not, google search "note 3 wifi issues" and/or "note 4 wifi issues"and look for answers there. In all likelihood the problems that are being experienced with Wi-Fi on the note 5 are similar to the Wi-Fi issues that the predecessors experience when they launched.

It's Lollipop. It's a known bug in the software since Nov 2014 and Google hasn't addressed it. I too had issues with my WiFi when I first purchased it. But I found the work around. The bug is in the security software. The WpA2-PSK with TKIPS or AES which is a catch all, reeks havoc on our WiFi chips. It doesn't allow the phone to have proper DNS addresses resulting in severely slow internet or dropped connections.
Solution: Change your security standard to WPA/WPA2-PSK without AES or TKIPS.

Is that a phone setting or a router setting?
Hey guys,
I've got an Australian Samsung note 5 that has wifi problems. It started not working all of a sudden so i decided to go along with it but after a while i felt the need to try and make it work again. So i went into recovery mode and factory resetted (thinking that it would help) but then on the boot up after i came to the setup screen and found out that i was screwed. The samsung setup screen doesnt let you go past the setup screen without any wifi. Please help, i wanted to post a thread but im new to this community so i am restricted.
Thanks
p.s wifi networks can be detected but only when the phone is held right next to the router.
I fixed same problem of wifi, its a setting in phone, but you need to root phone, its system setting in system folder.
Any updates on this? Im running one 920g completely stock and another 920g with hybrid n7 port v9. Both have this same issue.

WIFI slow / disconnecting

Hi
I received my 3T yesterday. I am having issues with WIFI
WiFi network drops frequently and the mobile data is used for some time and then WIFI is connected again. See attached .. This happens even when moving between rooms of my house
I think this happens when the mobile wifi changes from 5GHZ to 2.4GHZ when I move away from router
I have updated to OxygenOS 3.5.4 as soon as I received the mobile
The signal strength of the 3T is also very low
I have a 2 year old moto X 2014 and the moto beats the 3T at every place in my house
The signal strength and the wifi speed both are better in moto X
I have checked at various places
I have wiped the cache. Tried changing 2.5GHz to 5GHz
Changed Channels.. Tried all the things that I could find on the internet
But still problems
So is this a hardware problem and should I ask for a replacement? Or is this some Software bug which can be resolved
My router is ASUS RTN66U and a lot of other devices work seamlessly on that router and hence pls dont suggest to change the router
Awaiting replies
Regards
Ajjaykummar
I think this is a bug related to 3.5.4. On 3.5.3 my WiFi worked a lot better, but LTE Advanced is faster on 3.5.4. You can try a custom rom or downgrading, there's also a leaked OxygenOS 4 rom out.
Do you have wifi issues now when u have 3.5.4
I don't want to install new Roms. As I may have to return it in case this is a faulty piece
I'm having the exact same problem. I stream a lot. Very annoying when music video or gaming gets disconnect so often. My Galaxy Note 4, & s6 works fine.

yes, it started on 3.5.4.
here is a screencap of the issue
You can see in the screen cap that the mobile is connected to ASUS5 (5GHZ)
Then as I move away from the router the signal weakens and then the wifi disconnects .. and then it connects to ASUS (2.4GHZ)
Earlier it was connecting to ASUS but with a exclamation mark (without internet).. I waited for 15 minutes but it did not connect
Then I would connect if I switch off and on the wifi toggle
After that I did a factory reset and now you can see the screencap
It connects after a minor delay.. So is this alright
My other mobile - Moto X 2014 simply switches instantly from 5GHz to 2.4GHz and vice versa.. not even half of second is taken on moto x
Give the device a static IP use 2.4 network as it's more of a long range band. I tend to use the 5 band for stationary stuff. My WiFi works fine but all my home devices have a static IP.
This are the things that I did
1) Factory reset
2)Use Legacy DHCP client (under Developer options)
3)Disable Smart Wifi switcher (Advanced Wifi setting)
4)Static IP
This seems to solve the disconnection issue .. I still feel the wifi signal is weak compared to my other devices
Hope this helps someone facing the problem
regards
I had the same Problem on OOS 3.5.3/3.5.4/4.0 at the OnePlus 3T.
I tried every Solution on the internet and nothing worked for me.
But after i looked into my Router-Setup i saw the DHCP Section where i selected 'Renew DHCP every Day'
>>> Screenshot what i mean - imgur.com/KakQX3i.png <<<
After that it works perfect. No connection-issues anymore.
mine is already one day..
I thought it was resolved... but again I noticed slow wifi speeds
thinking of replacement
haven't had the phone long enough to experience disconnects but wifi is definitely slow...
I have a 200mbps connection, getting 160mbps on desktop with LAN cable, 110mbps on my OPO, only 50mbps on my OP3T....
all tested through speedtest with the same server location.
OP3T is chinese version flashed with oxygenos 4.0.1
edit: later tested again with OP3T getting up to 90mbps but still 20 less than the OPO
I have same issus like lajay. The Galaxy S7 from my wife works perfekt in the same Network!

*Fix* Slow WIFI with Bluetooth enabled

Since the Redmi 8 don't have 5ghz Wifi capability we are stuck with 2.4ghz wifi and on my 2 Redmi 8 devices with Bluetooth enabled that kills the speeds to about 5mb. Apperently Bluetooth and 2.4ghz wifi run off same hardware or software and don't appear to play nice together..
I use multiple different wifi connections a day and was a problem for me. Anyway so this was the workaround that fixed the problem for me and my device. Pretty simple and straight forward and suppose it could work on other devices with same issue..
Always only try this at your own risk.. *As Root is Required*
First off: I'm located in Canada, could be different in another region.
I have a unlocked bootloader
latest stable Xiaomi.eu rom for the Redmi 8 installed
Official TWRP installed..
2: *Root Required*
Download and Install latest version of Magisk and flash via TWRP
3: Download and install Service Disabler from Playstore and Grant su permission after opening the app .
4: Search for Google Play Services and click on that .
5: Scroll down the list till you find NearbyMessagesService and click it to disable it permanently.
6: Now Make sure you have Google's "Nearby" functionality disabled
Go-to your Google account - Device connections - Devices - Show Notifications off.
Now back to settings - Passwords and security - Location - Scanning - turn all off
And reboot.
Now my other device is on stock MIUI and I haven't tried this on stock rom as of yet. It's my wife's device so if she lets me I will test this on her device as same issue is present.
In time I will try to see if this "fix" will retain if I unroot the device after..
*Update* this will continue to work if you unroot device.
*Update* when I installed latest Xiaomi.eu rom 11.0.10 sometimes it don't work till I reboot. Not sure why yet.
thanks for sharing
but for me I just changed the Channel used in my router and everything works fine

try channel nom 10 or 11
guys you have slow wifi because your wifi and bluetooth are using 2,4ghz they interfere with eachother you need to download an app like wifi analyzer and go to the last tab then look which channel isnt used and use the channel which isnt used i hope i helped you
without root is there any fix?
Yes WiFi and Bluetooth in same frequency range but that should not cause problem. My mi 8 lite manages to communicate with my mi band 3 and use WiFi ok. I had an ulefone and that worked ok. I had a blackview and that worked ok. The redmi note 8 pro did not. At first I thought it was maybe a bad chip that was leaking so tried another with same result. So its hardware related or software. But it's not the fact of both using same frequency band. As Bluetooth is not as strong a signal I would have expected that to drop not WiFi.
Xiaomi should have sorted this by now. Miui 12 still hasn't fixed this.

This is a big problem and Xiaomi should fix in the next update!
However if you mainly use Wifi at home, change the wifi frequency to 5ghz and the problem is gone.
In my modem/router you can do separate 2,4ghz and 5ghz networks (both work at same time), so my Laptop and Xiaomi phones are on 5ghz (a lot better speed in both) and old hardware are in the 2,4ghz network.
Didn't know this before, but now also my laptop wifi speed came from 30-40mb-> 120mb.

Are you kidding me? Well, what a waste of mobile I have bought ... everything is fine except for something as important as connectivity. Ok Xiaomi ... Does anyone know of any ROM that this failure does not pass? so far all the ones I've tried happen the same ... :crying::crying:
I also tried the proposed fix (on latest Stock rom / Android 10) and unfortunately it did not work Any other suggestions how to solve this extremely annoying bug?

Install a custom rom like HavocOs
I have the solution ===>>> youtu . be / WMksEEKXlJY
The problem is interference with Wi-Fi and Bluetooth Scanning.
DISABLES THESE TWO CONFIGURATIONS
On MIUI 11:
SETTINGS >> Passwords & Security >> Location >>> Scanning >>>
Wi-Fi scanning> (OFF)
Bluetooth scanning> (OFF)
On MIUI 12
SETTINGS >>> LOCATION >>> Scanning >>>
Wi-Fi scanning> (OFF)
Bluetooth scanning> (OFF)
This will solve the problem of drops in the wifi.
It is NOT POSSIBLE to use Bluetooth in conjunction with wifi. But with these settings disabled, you can use wifi with better quality (as long as Bluetooth is disabled).

Thanks. I watched the video, but unfortunately it is not in English, so I didn't really understand what the actual solution is. For me it seems, that your main "trick" is to switch from 2.4GHz to 5GHz WIFI, is this right?
Would it be possible for you to write a short manual on your steps here in English, that would be great!
Thanks, Lars

Thanks for the update.
Have already disables these options, but was hoping to be able to use Bluetooth in conjunction with WIFI, since my smartwatch is always connected to the phone by Bluetooth
So unfortunately no final solution for me :crying:

It worked!
Thanks for the suggestion, moving from channel 6 to 13 did the trick! I can finally watch videos with Bluetooth speakers.
Would Xiaomi.EU fix these issues? If so, I'll aim for that ROM!

Question WiFi Problems

Hi community,
I'm writing because I have a strange WiFi problem with my S21 Ultra which I had with no other equipment before.
Setup:
- Galaxy S21 Ultra
- FritzBox 7590
- Fritz WLan Repeater 1750E (2x for better range coverage)
- WiFi 5G Auto channel WPA2/3
- WiFi coverage is good (tested with a lot of other devices)
Phone Setup:
- Paired with the WiFi
- Do Not use Mobile Data
- automatically reconnect to wifi
Problem:
The phone does not automatically connect to the WiFi.
The phone also looses the connection to the WiFi several times a day.
When the phone is not connected to the wifi I open wifi settings.
- It happens that the wifi list is completely empty and the circle animation indicates that the phone is searching for nearby connections
- It happens that the wifi list contains a list of wifi networks the phone has seen before when it was connected last to a wifi
- Switching off an on the wifi helps to find the actual networks and the phone then connects back to wifi (most of the time)
I tried already several settings and combinations but so far none of them brought any success. So I would like to know if someone else had a similar issue or has an idea what could go on here.
To me it seems strange that the wifi scan is not working as I would expect it. I would expect the phone to continously refresh the wifi list with networks it sees, but always when the phone lost its wifi connection the list is not working anymore.
Try tinkering with the wifi channels and encryption until it shows up.
Or you can try resetting the routers to see if it does anything

Has anyone else have WIFI connection problems ? With not finding any WIFI until i factory reset it? And after a few days the problem reappears. Last time i didn't factory reset it and after 3 days, with no adjustment, the phone found WIFI, but...

You said the phone loses connection and etc. Does that happen only at the location you described, or does it also happen at other locations?
It is possible that your phone also gets confused with the router and the repeater.
1st you need to clearly understand if the issue comes from the phone or possibly from your WIFI devices. Once this is clear, you have something to go on with...

- Phone is on standby (placed on a table, etc.)
- I turn it on to check messages,
- No connection to wifi
- Open wifi manager
- No wifi networks listed at all
I do not know why my router/network should be the problem. All other devices in the wifi work flawlessly. It cannot be that I have to restart my wifi router every time the phone finds no wifi at all. That makes no sense to me.
It looks more like the android wifi service is still on sleep and does not report new wifi networks (which would be necessary also to see any wifi at all).
May I suggest....
Settings -> Connections -> Wi-Fi -> (three dots it top right) ->Advanced
Make sure "Turn on Wi-Fi automatically" and "Wi-Fi power saving mode" are both off.
If you use a repeater is it a mesh or AP solution? I find Android will drag its feet letting go of a wifi signal even when walking into range of another known network. Had an extender in garden and even when down to 10% connection on Wi-Fi it would stay connected to extender, I had to turn wifi off and on quickly to get it to pick a better network.

It seems to be the phone...
Definitely try what lywyn suggested...
you can also submit an error report on Samsung Members app, it sends reports directly to Samsung and get the feedback.
Download the app from the Galaxy Store if you don't have it on your phone > Memers app > + button > Error report

Unfortunately no success. I configured exactly like suggested. Does the S21 Ultra have problems with handover in meshed WiFi setups?

Never had any problem with my S21U (Exynos) with my Mesh WiFi (Deco X60) setup.

sometimes it happen when you connect at certain locations.
If you haven't already done so give this a try. Settings, search "Wi-Fi", scroll down to Location, Improve accuracy - toggle on, Wi-Fi scanning - toggle on.

Mesh is a single network solution so should not be a problem.
The only other thing I can think of is the power-saving mode. My son has his Pixel on power saving all the time and I know sometimes he has to turn off/on wifi to get a connection when waking the phone up
I found the issue! It is WiFi Direct related. The app "nexar" from the dashcam is interfering with normal WiFi on this phone. Nexar conquers the WiFi functionality and is responsible for my wifi disconnecting. The app requires the "Location always" permission. If I remove this permission my WiFi works again normally. So: one has a similar issue: remove "Location always" permission from the nexar app. In my case it helped.
You said the phone loses connection and and many others. Does that show up best on the region you described, or does it also happen at different places?
Kodi nox
It is feasible that your phone additionally receives harassed with the router and the repeater.
1st you need to honestly recognize if the issue comes from the cellphone or likely from your WIFI devices. Once this is clean, you've got something to go on with...
