Connectivity issues like the gs4 - AT&T Galaxy Note 3 Q&A, Help & Troubleshooting

Anyone having issues keeping LTE or a wifi signal? I had this on my gs4 and it infuriated me. Happening Again On The note. I didn't have the issue with the HTC one or note 2.
Using wifi analyzer the wifi signal looks good. Idk why it's being so slow and unstable. Newer linksys n router.

Yup. I turned off the setting where it turns off wifi completely if the signal is unstable. Kept doing it while using my chromecast so it disconnected from it. None of my other devices have an issue

I turned off the wifi scanning and I got a message about my wifi signal being bad even though I'm 10 feet in a direct line to my router. I also cannot keep an LTE signal around my house, but my S4 manages to without issues. Turning on airplane mode will lock an LTE signal for about 2 minutes and it reverts back to 4G.

I turned that off as well. Having it off or on hasn't affected much it seems. I'm also very close to my router with nothing blocking. I don't get it, thought the plastic was supposed to improve connectivity?
Like I said, I've only had issues on this and the gs4. Girlfriend has a gs3 which doesn't have issues.

Maybe you just keep getting a lemon device? Mine seems to work fine and my S4 did too

Possibly. I read about others having these issues on the gs4. Obviously not everyone it would be my luck to keep getting lemons.

LTE
Yep, got mine yesterday (10.5) and it wont hold onto LTE. I can turn on and off Airplane mode and it will lock onto LTE immediately, but after about a minute, it drops back to 4G. NONE of my other phones did this (S3, S4, HTC 1, Optimus G Pro, Skyrocket, etc...)

Wifi kills my reception

I am on the leaked update and have always had crappy reception in my house. I have 2 different wifi networks and a total of 3 wifi routers. I also have a z-wave network. None of this had ever interfered when I had AT&T with my captivate. For some reason, my signal goes to **** when I turn on my wifi. If I then it off, I watch the bars go right back up to 4. Turn it on, down to 1. Anyone else seen this problem?
Sent from my DROID BIONIC using XDA App
no, b/c I stay on WiFi at home, and my cell signal always looks fine.
What bands does your Z-wave support?
It has to be something internal to the phone. When I have my wifi off, I get excellent cellular and data reception.

Weak lte signal

Does anyone else notice a weak lte antenna? Been stuck on 3G where I had full 4G with the EVO LTE. Otherwise I love this phone. I can just stare at the screen, it's a thing of beauty.

I've actually noticed this as well. Do u use a case? I'm wondering if it maybe has something to do with that. Gonna test when I get home from work.

I dont know if it has anything to do with it but i shut off The Sleep Mode in settings/power and it seems like my 4G is alot better. It could be my imagination but it sure as hell seems better! Lol
I'll give it a try

Found what I believe is a solution. When I changed my network mode from cdma/lte to automatic, my signal changed from 1x to 4g. Strange but true, makes a huge difference

Im really starting to notice as i drive all over Florida(im a driver) that it its not holding 4G as well as my Note II...In sensorly it gives you a good idea where LTE is available,hell i logged a bunch of what is seen in Florida and im noticing in light purple areas where I had 4G before i have to now be pretty stationary for the One to lock in to 4G..But the real kick in the sack that has been driving me crazy these passed 2 days is seeing 4G on the phone and start doing something which transmits data it drops 4G and goes back to 3G..Happened at least 7 times today
Quite honestly, I had this issue pretty much with all my Sprint LTE phones, and I had pretty much all of them. Of course some held LTE more than others, but I was still getting frequent drops. Until Sprint moves into the 800 frequency, Holding LTE is going to be a consistent problem.

At 1st I was ready to return the phone because of it but decided it's really not worth it..Central Florida is only at 28% so things should improve once LTE is a little more dense and not so much distance between each tower that has been upgraded..And if i get my panties in a twist I can always go back to the Note II untill more towers are lit up.
Sprint LTE is the Swiss Cheese of 4G...
Yea same here my signal doesn't stay connected switches frequently as compared to my S3 which held 4g constantly Im in Lawrence KS we got good lte signal here

Poor signal reception on AT&T with AT&T Note 3

Switched to Note 3 from Lumia 920 (phone upgrade, had my SIM replaced as well). Now on all places where I previously had stable LTE signal my Note has couple bars of HSPA or from time to time HSPA+. I still can catch LTE signal from time to time but not in the area I live (and had stable LTE for a year on Lumia).
What may be the reason? Is it a phone problem or just Nokia modem has better sensitivity?
Don't want to initiate replacement procedure, the phone seems perfect in all other aspects...
I've also been disappointed with the reception vs the S4. I'm also having trouble installing apps from the play store >.< even on wifi.
I have bad reception also
I am thinking of returning, I have had to switch to airplane mode twice in the past hour to get it to reconnect to LTE. It sometimes drops out all together when accessing the play store. I am in Baton Rouge, and didn't have any issues on my iphone 5.

That's crazy, I'm in Baton Rouge too.Just got my Note 3 from the Best Buy Mobile on Bluebonnet. Maybe its borked because of the impending hurricane doom.
Yes, switching airplane mode on and off helps to establish LTE link everywhere... But it switches back to HSPA in 20-30 min and never return back by itself. Definitely software bug
I'm getting much better signal than I ever got with my 920 or S3. I'm in Houston FWIW.
Sent from my SAMSUNG-SM-N900A using xda app-developers app
I'm from just south of Baton Rouge, reception has either been great or next to none for me. I can manually put the note 3 on lte but the speed at that point is slower than the 4g. Sadly my s4 active was nearly the same way...

Yeah, maybe the storm is causing issues ,I'm going to give it a few days.
In the same room, my wife's iphone has 4 bars and this one has 2

I'm east of Baton Rouge, in Hammond, and I've seen the same thing! lose LTE and sticks to HSPDA! Airplane mod does fix it as well. I hope it's the storm, but I don't thinks so!
For you guys with a Google play issue...
If you connect to a VPN like privateinternetaccess.com (also avaliable on the play store) and select a country other than the US it will more than likely work.

I live in SF Bay area and this definitely not storm, it's some software/modem firmware fault. It seems not trying to switch to LTE once kicked to HSPA. If I do airplane mode switch on a place I have good LTE signal it would jump to LTE and keep connected for a long time until I move and it loses it. After that it jumps down to HSPA and not trying to return back on LTE even if I go back to same place where it had full bars of LTE before
Well good to know it isn't just Southeast Louisiana. Also, just plain nuts to me that we're all posting in the same thread miles apart, go figure.
I haven't had time to switch my Sim back to my S4 to do some testing. But I feel like my speeds are definitely suffering.
Post your speed tests for comparison. BTW one of my favorite features about the s pen are the easy screen captures and edits.
Maybe it's just an APN issue? Has anyone tried playing with that? I tried a few from rootzwiki but don't really know what I'm doing in the APN neighborhood.

For what it's worth, FL is having issues as well. Play store has been wonky and the reception has been less than stellar. With all these reports I'm willing to bet it's something on their end.
I am going to try and swap it out at the local store tomorrow even though I ordered it online. I should be able to according to the terms. I am willing to give it another shot, although at work today I had absolutely zero signal just a circle with a line through it. I normally get at least phone and text functionality at work.
All your phones are perfectly fine - they just need a firmware update or two.
I've seen mine even drop off to edge just sitting here at my desk.

[Q] Weird Wi-fi issue

I love this phone but have one strange concern, I've noticed that it likes to say my Wi fi is unstable yet I know it's perfectly stable has anybody seen this or experience it?
Sent from my SAMSUNG-SM-N900A using XDA Premium 4 mobile app
Yes. I have similar problems with my wifi if I have it attached to my 5GHz wireless network that I know works fine.
It is particularly bad if the router is in N+AC mode.
Once I switched onto a 2.4GHz wireless network I haven't had the problem since.
For whatever reason my note 3 wifi has been really flaky on 5GHz.
I brought this up in the stupid questions thread a few days ago.

I got this error a lot the first couple of days. I played with the wifi settings a lot, and it seems to have "settled" down.
I was getting "unstable" error sitting feet away from my router. However, I just walked around 200 feet away from wifi at work and noticed it was still connected.
Edit:spoke too soon. Doing the same thing now.

the weird thing is is that it never loses the connection and my wifi speeds stay consistent at 64mbps
I get it a lot... I tried it with my 5g and it happens once or twice a day. The 2.4 ghz is even worse it happens about 7-10 times a day. I used my MiFi and it was 3 ft from my phone and it did it as well. Not sure the cause.. I have auto switch and Bluetooth off

This has happen to me a few times also. When It happened I looked at the connection in settings and it says very strong........but yet unstable...that doesn't make sense.
yea this happened to me..never had a wifi issue on any device but I refreshed my modem & router now all is good

If you disable this, it will stop prompting you about that and will also stay connected to not so great WiFi (if you have crappy WiFi).
All wifi has unstable times. What ahent929 said to do is correct.
This phone is designed to detect a drop in the signal. That's why it says it's unstable. Even if you have the absolute best router in the world, keep in mind the other radio frequencies that are passing through yours as well vis a vis.

It should more than help, it should correct it for good and not pop up anymore about unstable anything.

Swift kick in the throttle

So just got my note 3 Tuesday and am now experiencing blazing fast 0.45 mbps avg speed tests. I've tried searching for solutions, including the *# combinations that some people have luck with in the dialer, and none work for me to try and switch the signal. I don't mind settling for hspa only if need be as it's not long until the cycle restarts, but some repeatable solution would be fantastic. It is not rooted, but I do not object if there is no other solution at all. Any ideas, input, or suggestions would be greatly appreciated. Thanks in advance

I can't edit, but forgot to mention that it is dropping LTE signal everywhere I was fine on a note 1 and 2, and sitting right next to a gs4 with a good LTE signal, it would continually be on "4g". A restart or airplane mode on and off quickly will get it back on LTE but only temporarily. Is this typical behavior of a throttled phone, or could I potentially have a defective piece of junk?

The note 3 seems to not like lte in my area either, I don't think it's a hardware issue since it traded my first one back in and the new one does the same thing

Mine was doing the same thing. I did a hard reset (or 2] and it's running great. Locks onto LE and I'm getting 30mbps +. You will lose all your data though. ?

Make sure all your APN settings are correct and that your network mode is on LTE/WCDMA/GSM.
Thanks for the replies. I don't mind resetting the phone, just want to make sure it isn't a physical defect that needs me to return the phone. The lte here is normally very solid, I had no trouble on note 1 or 2 really.
How do I check the APN settings and see the lte/wcdma/gsm menu. When I searched I only found dialer codes that didn't work no matter how or how many times I tried them. None seemed to be specific to note 3. Google searches as well as using the xda app don't return anything, but maybe I am not searching correctly?

I tried the gsm lte settings and it never worked no matter how I tried. Restarts combined with changing the settings with that #* method and no such luck. Will I have to root to find a solution?
I never had been throttled before last month. Now I just got it again as I tipped 5gb.
I have 10 days left too on the billing cycle. That is gonna suck as it just got me again today.

That can't be a one off. This phone is on "4g" a number of times I see other phones on LTE. I'm not sure how next generations get worse as it is weaker than my note 2 was, but you are not alone for sure.
