[Q] Ready to throw my GN against the wall. Wifi wont stay on!

Hi all, Im having a problem that is slowly driving me insane for the past 2 weeks. I surely cant be the only one. Anyway, I generally move between home and work daily, both have WIFI. When Im at home Im connected, all fine. I travel to work, WIFI isnt connected, again this is normal. I get into work and when I expect it be connected to WIFI it isnt, WIFI is off and I have to manually turn it back on to get it connected to WIFI again. Why do I have to do this? Why have all my other Android devices just worked normally and reconnect to known networks. Its soooo frustrating
Anyone have same problem or have a resolution?

What rom?What settings in phone wifi?

Both Stock rom, with and without the volume fix, and Modaco MCR4. Wifi settings are set as WIFI on even during sleep.
Is there some settings Im missing somewhere other than in Settings > Wireless & Netowrks > Wifi ??

Nope these are the settings.The strange thing for me is that your wifi turns off automatically

Try going to advanced WIFI settings and disable 'Avoid poor connections'

Yep. Try that. Only thing I can think of. My wifi was flaky with that setting on even 4 from my router. If that doesn't solve are you using any kind of task managing àpp?

I have posted this in other people's threads in regards to poor wifi reception. I recently purchased a 9250 through bell canada and have the same problem.
I have turned off the 'avoid poor connections' as well. It turns on and off on its own and can't get through a download of more then 5MB on wifi.
It will also reconnect on its own if I have left wifi turned on. I would say while WIFI is turned on I may actually be connected 30% of the time. This is 90% in 2 feet away from a router.

I'm having the same issue (wifi turning itself off) - noticed it the other day and just assume I'd caught the wi-fi button (I use extended controls). Happened again this morning and also just now as I got home.
I've not modded anything on my Nexus (4.0.1) - avoid poor connections has been disabled for a while.
I may test the theory, but betweek home and work is a wifi enabled bus journey, I never use it but it always tells me there's a wifi available. I might turn wifi notification off and see it if turns itself off before I get to work in the morning...

Left home with wifi on... Got to work and wifi was off? Wtf?
Could it be extended controls?

You are not the only one, it's happening to me in exactly the same scenario. Oddly enough it hasn't happened today.

i cant make out of your post thast the wifi on/off button turns of? or just the connection to the wifi adres?
i dont know about any sleep or auto turn of policy's as i didnt try it(i always turn off my wifi when travling)
but if its the last thing.
than the problem might not even be the GN.?
but the router it self.
even computer's and laptopt can have problems when the password is too long,or to different(hard characters like :';/.m,[email protected]#$%^&**(() ][ )
it might also be the MHZ setting,as the 20MHZ has wider range but can be disorted by machines like microwaves.
but the 40MHZ has lower range but wouldnt be disorted.
as there is also the channel option thats has been set wrong/or the pasword encryption. or any other router conflicting with the router you want to connect.
it might also be the router not liking your GN.(as my spica doesnt conect to my router at home,but all my other devices do.my router doesnt want to give a IP to my spica.)

It just happened to me again now, left the office whilst wifi was on and connected. Grabbed some lunch and returned (about 20 mins) and now my wifi button is set to off and I need to set it back to on.

Are there any policiys or settings for auto off?
you might also want to look into the power setting's,might be a power save feature.
And you are running stock? or??

Can't see any policy settings or any power save features. Running stock.

somehow I have fixed it. Problem is I don't know how.
Here is what I did in case anyone else needs help;
*From the 'My Vodafone' app, select wi-fi finder, in settings untick 'Enable BT Openzone'
*Settings, wi-fi, advanced, untick 'Network Notification', untick 'Avoid poor connections'
Not sure which of the above actually fixes it but my Wi-Fi has been on for about 1 1/2 days now.

Have you or when did you upgrade to 4.0.2? As the changelog mentions a wifi fixed. Only upgraded this morning so won't see if it has worked until I get home...

So I am still having this problem since day one. I have travelled through 3 countries and multiple cities and tried to use WIFI in at least 20+ different instances and the problem is the same.
It connects right away (really quickly actually) will stay connected for a bit then eventually loses connection.
I can't download any of the big packages for the games and so I can't play them. I won't use my data connection for anything over 100mb.
I got a message for an update yesterday. Updated the phone but I see no difference in the Android version number.
Anything happening with this?
I thought the update i was downloading was 4.0.2 but i guess it wasn't.
I am familar with updating and flashing from the galaxy s. But I want to use the phone completely stock for while.

I have just returned my nexus for a replacement. Lets see how it goes.
So far I have had the power shut off once while toggling the wifi widget (never happened on my other phone). And the wifi has disconnected twice. I have just done the update (not 4.0.2) and it seems to work a little better.

Called samsung yesterday after getting the replacement phone when it had the same issue (just as a reminder I have tried it on numerous routers/ap's) and they said they hadn't heard of the issue.
I said I was just calling to provide some feedback. They told me to return the phone yet again. I obviously believe I don't have a problem with the hardware at all. I figured if store let me return it, then why not.
Anyway onto my 3rd one today and the exact same problem.
I think that even though I am turning off "Avoid Poor Connections" it isn't actually turning that 'feature' off. Every so often and only if your watching the wifi settings it will say that it disconnected the wifi connection due to low signal.
Mind you all of this is 1' from my router while sitting at my computer. My galaxy S is sitting beside me and has maintained a wireless link to the router the entire time.

[Q] WIMAX disconnects and never attempts to reconnect

I live in the suburbs of Houston where the WiMAX coverage is kind of spotty. If I leave an area of coverage for more than like say a minute, my 4G will stop attempting to scan for a new 4G signal and never attempt to reconnect even if I enter a new area with 4G coverage. I have to manually toggle the connection in the notification bar.
I've searched the forums and noticed several posts describing the same issue.
Does anyone have a solution?

Bluetooth is not turned for on my device.

Bump. Anyone else having this issue?

I'm using the phone app so I don't know the link, but there's a link in general, I think, that describes increasing 4g performance. There's two simple tweaks to do and some involved ones. I just did the two simple ones. One is to change the retry interval down to 15 seconds and the minimum signal level for 4g lock is -110db. Those two changes made a noticeable improvement on fringe areas and inside for me.

I did those tweaks, that is not the issue. I have tried all the WiMax_Scan_Retry from 1 to 300 and the WiMAX will never reconnect.
For example: I do not have 4G at school and I have 4G at home. If I drive to school, the 4G will disconnect.
Then when I drive home back into 4G coverage and go to sleep even after 10 hours, the 4G will not reconnect.

Bump!!! Also have this issue.

Try doing what most people do, when you know your leaving a 4g area turn it off. Then turn it back on when you get home. No sense in wasting battery. That and it only takes a couple seconds to turn out back on and reconnect.

I have extended battery that will literally last days even with 4G on so that is not an issue for me. Besides, this is not a viable solution if I want 4G in the car and it moves in and out of areas of spotty coverage. 3G where I live is about as fast as 1x.

Mod? Rooted? Modem?
Is your phone software on stock?
What OTA updates/mods are you running?
Kernel/Modem versions?
It would be good to know of the people seeing these problems have similar software/mods/modems.

I agree. Post your setup in detail. It will help to narrow this issue down. For example I had similar prob's on EL13 modem but with 26/29 flash all is good.

I tried these:
Stock/Stock+Root/Starburst/Caulkin
EK02/EL26/EL29
Rogue1.3/1.4

This may be an example where adjusting the WiMax settings in ##data# with MSL number will help. Try lowering minimum signal picked up from -89 to -110, you can also change how long it stays connected and how fast it reconnects too...and here's where to read about it all...I did it on my OG Epic, Nexus, and this phone but slightly modified settings..it could also be a kernel thing too. Some of the Nexus ICS ones do that and wont reconnect until you go into settings and toggle

Ok now it's time to go to your local sprint store. Im outa ideas. You have done morethan most B4 choking a rep.LoL.

I have this same problem.. Sometimes sitting in the living room. When im outside i get 4 bars of 4g but inside i get 1. if some reason i get disconected, it seems to switch over to 3g and stay there without scanning again. If i walk outside again, still stays 3g until i toggle off and on 4g again....

Anyone know of an app that will toggle 4g for us when it loses connection?
Or maybe a tasker profile? I tried in tasker, but I can't seem to get it to do more than basic things. There a couple spots in town that always lose 4g when I drive by and never reconnects as well. 3g is slower than when I use roam control on 1x verizon.

I'm having the same issue with Wifi. It'll still show as being "connected", but there won't be any data coming through. I'll have to toggle Wifi on/off to get it back. Sometimes it'll work for a couple of hours before having the data issue again, sometimes less than a minute.
I'm on stock, rooted.

Connections optimizer is off for me too - My phone shows a clear signal disconnect and reconnect (The wifi bars/3g symbol disappears completely) during this time all data connections fails - including texts. This is happening when I'm staying in one area so it couldn't be a tower reconnection issue.
I'm going to try taking my phone into a sprint store today to see what they say.

Ah, it sounds like our issues may be different then. My issue is solely with Wi-Fi (haven't noticed issues with 3G). When it happens for me the Wi-Fi icon in the status bar doesn't change, I just can't connect to anything.

Yup, same here. Seems like the 3G radio does the same thing, but not necessarily at the same time as the WIFI. At first I thought is was only the WIFI too, but 3G is affected, though not to as severe a degree. My WIFI was actually disconnecting and failing to reconnect. Turning off connection manager made no difference. I did however notice that the WIFI at my work (WEP encryption) never seemed to do this (at least I didn't notice), so I changed my home network WPA to WEP and sure enough, it stays connected. Was still failing to load occasionally, so I went even further and changed the router to a single channel rather than "Auto" and set it to "N Only" (due to having a similar problem with a laptop I used to have, with a similar solution). Problem fixed. I'm using an Amped R10000 just FYI, not sure if it matters. Very annoying, and given the number of occurances being sufficient to start a thread, I'm assuming this is a common issue and will hopefully be fixed by a firmware update. In the meantime, we should probably all start calling Sprint daily and complaining. Maybe they're not even aware of it. Probably not enough of these phones in circulation yet for them to worry about it.

Mine will do this from time to time. Stock not rooted. I will have full 3g bars and full wifi bars and my data will just hang. If I turn off wifi everything works again. Some times when I load a game that has to connect to Facebook to play against friends I have to close the app/game, remove it from memory and reload it to get the data to work. Same thing for Pandora. It will load a song to 2% and hang until I stop wifi or reboot the phone. It's not an everyday thing but some days are worse then others.

"Good to see" from the perspective I thought it was just me. Things described by others happening to me as well. Personally, I find I like the wifi/3g auto connectivity feature - when it works. Got my SGNII on Thurs last week, and connected to wifi at work on Friday no issues. This morning, the Note picked up my work wifi without a hitch.
At home, over the weekend, I was getting spotty connection, sometimes no connection to my wifi. (Disclaimer - I have my main wifi @ N/5ghz. An access point was added with wireless G via an old Netgear router-turned-AP.) After several attempts of moving the AP from one cat6 jack to another, I finally moved it to my main level. Oddly enough, so far, so good. Certainly possible the router's radio is pooping out.
What I notice happen with connection issues though seem related to the Note seeing my wireless G, trying to connect, but unable to do so until/unless I reboot my phone. After moving to the new location/jack, everything seems to work OK now (knock on wood).
Having said that... I also think the 3g radio (HW or SW?) is a bit wonky, as my old HTC Hero seemed to have more bars at home, IIRC. Whatever it is, just seems a bit lacking, IMHO.

Sprint is updating to LTE in many markets ive noticed my 3G drops says preparing networks and reestablishes the connection to 3G. I live in Fort Wayne and issue the permits for the tower co-locates and they are close to going live with LTE here so I know thats my problem. I can live with the flakiness for a few more days. I have not had issues with WIFI drops at home.
Sent from my SPH-L900 using xda app-developers app

The same thing has been happening to me here on Long Island. 3g drops and reconnects. Sometimes it doesn't and a reboot fixes it. I also notice after the disconnect and reconnect it states my PRL is unknown. I have done a PRL update many times, a Profile Update, a RTN reset, and a factory reset. This happens on the stock rom and any custom ROM. It's driving me insane!

hmm maybe mobile settings?
Ive found LTE/CDMA setting to be not so good.
Its providing me eHRPD signal which is stop and go web browsing is murder.
CDMA only setting is providing Rev A signal fast web browsing

Sigh, so it seems as if you guys are losing wifi/3g....is it affecting voice radios or LOS/dropped calls?

I haven't been on the phone when it's happened so I couldn't tell you - Nothing like the LOS on the E4GT. When the data connection does cut out it immediately reconnects. Doesn't really impair the functionality of the phone but it happens enough to be annoying. With a 300$ price tag I expect my device to be without defect.

I'm not having LOS /dropped calls just data creep with LTE/Cdma setting enabled.
Speed test show same data speed numbers as CDMA only setting but when browsing data arrows tend to pause more making for slower page upload with LTE/CDMA setting enabled.
According to Sprint store tech such performance is common with that setting.

I am on CDMA only. I should have mentioned that in my first post. This does affect phone calls too as ill be on the phone and the call will drop and the "out of service area" message comes up. It doesnt matter if I'm on my Airave or not. I tried different prls which doesn't seem to make a difference. I am starting to think there is something wrong with the phone as my girlfriends S3 doesn't do this. Maybe Samsung will release some sort of update to fix this issue.

I made the change back to CDMA only mode this morning and it has solved my WiFi issues as well. I was also struggling getting a GPS lock with LTE enabled. GPS toolkit would show 20/21 satellites found but it would never get a lock. After the reboot back into CDMA mode it locked in 5 seconds.

Note II drops WIFI Calling??

Hey I'm a 1st to T-Mobile i'm testing it out before I switch all my lines from Verizon. The question I have is that both the Note II and the GS3 that I have seem to drop the Wifi calling feature randomly. I thought at 1st it may have been some sort of power saving option but it seems to happen in frequently. (Doesnt matter if I'm close to the Router or not)
Is this common? Or am I the only one that has had this happen?
Thanks for any input!

mine goes on and off on both my new note 2 and my wife's new galaxy s3. really aggravating. worse on my phone, when in wifi calling, it only answered calls like 1 out of every 10 times, otherwise they went to voicemail. I took the sim out of mine, then put it back in and pushed it in and out and in the holder a few times and now it seems to receive calls in wifi mode but still always in and out and error to connect and such.

My experience with Wifi-Calling has been nothing but troublesome. It's really not reliable at all, sometimes calls comes through sometimes don't.. and when it does come through I can hear the caller but caller cannot hear me. This is quite common problem with wifi-calling and i given up.
If you get even a 1bar of reception near by the window, I suggest calling T-Mobile and getting their Cel-Fi device (Free of charge but has to return when you leave T-Mobile). 1~2 bar by the window will give you full 4bar reception throughout the house on 4G. Only requirement is that you must be living in single house, can't ship out to house that are connected by or close by. I live in townhouse and I just told them I live in single house and got the device in 3 days. =)

Wi-Fi calling is a disaster. For me, incoming audio drops constantly, but the party I am calling can hear me fine. On other occasions, the call will just randomly drop. Came from a Sensation where Wi-Fi calling was perfect. There does not seem to be any resolution... I have spent hours talking to tech support and they have replaced the device with no improvement. I have also had my ISP out and they have verified that my connection is fine. I have even changed the router out... same issues.

With my wifi calling, as soon as I turn kt kn my bars at home would drop where I would hardly get any service. As soon as I turn wifi calling off I magically get bars. So I leave it off and now I get bars pretty much everywhere I go....almost

With wifi calling on, it's suppose to drop signal bars to nothing. You have to go by the wifi bars instead.

Wifi also greatly depends on your network conditions. Cause I have the same problem but it doesnt happen to me that often after some tweaking.

Wifi Issue
I have that problem quite a bit but the signal strength on my router is good. Yesterday i had my internet company reset the cable modem and my wifi problems have decreased a lot but it is still happing. It has to deal with the wifi certificate problems on the Note 2 (Samsung). It is the same problem that I had on the GS3.
Oh well

No issues here with wifi calling.

With my wifi calling, as soon as I turn kt kn my bars at home would drop where I would hardly get any service. As soon as I turn wifi calling off I magically get bars. So I leave it off and now I get bars pretty much everywhere I go....almost

Uhh, that's the point of wifi calling, to make calls over WiFi and disable your cellular radio. If you turn on Wifi Calling, you should get a blue phone icon on the top left and your "bars" should drop to nothing as your phone turns off the cellular radio. You can still make/recieve calls/sms/mms.
I've been getting an ER01 error lately with invalid certificate, but it seems to be a T-Mobile backend problem? It happens, about 10% of the time and only on my school's network (I have a feeling, it might have to do with the sign in process there).Otherwise, it works well at my apartment.

i get that certificate problem at my house, not too much anymore, but I still see it. and the wifi calling does drop in and out at various times. not a huge deal for me, but the average person wouldn't deal with that.

I've been noticing more & more problems with my service in the last two months. I called T-Mobile to fix it and whatever they did seemed to only help a little. I get times where I get frequent ER01 errors with WiFi & duplicated text messages (same text message gets received by my phone 2-3 times) for an hour or two. I used to also get errors sending texts around that time, but that appears to have gotten better.
Someone else mentioned Uverse, and my WiFi calling problems are at home & work, both of which have AT&T for internet... When I switched from their DSL to Uverse I expected less problems, but got more.

Seems to be a problem that a lot of people are experiencing. Just did a quick Google search and some indication points to a possible T-Mobile back-end problem. I wonder if i call up T-Mobile and ask for wifi calling to be explicitly added to my plan if that'll change anything.

Network loss

Ok guys, having a real problem here. Often when I am connected to either 3g or wifi my phone will stop picking up signal suddenly. AIt's almost every time and I will have to disconnect from the network manually and reconnect and it will instantly pick up signal again for a while then it'll repeat. When it suddenly stops it doesn't show on the status bar that I have lost any signal. With 3g its kinda just at a stand still not receiving or uploading and with wifi it just stays the same but I'm still not picking up a signal because by web pages won't load neither will other apps that require network load until I manully disconnect and reconnect. Is anyone else having a problem like this? I don't think it was like this when I firs got my phone a month ago. I'm at a loss. Any help is much appreciated. Oh I'm completely stock btw haven't rooted........(yet) lol

It has happened to me a couple times that I have noticed. I will be streaming music and walking and all of a sudden, nothing.
Even a soft reboot does not help. It will require a full reboot generally to solve the issue. I have not been able to identify the issue specifically. I suspect it might be related to LTE testing in my area.
What's the LTE status in your area?

No lte yet but as I stated earlier it happens on wifi too. It'll still show that the signal is connected but my pages want load at all after it happens and when I try to refresh it'll say that the webpage could not load because there is no network. Only until I manually shut off 3g or wifi in the settings and turn it back on will it pick up signal again but only for about 5 minutes. This has happened in various locations on 3g and wifi and will even happen at home wifi.

This has happened to me as well... A lot . Stock.. on various roms.. No lte as well.. But it's in the works

I've had this problem too. Sprint replaced my phone and it never happened again.

I think reactivating hands free actually fixed my problem...for now anyway. It's not losing network like it was before. All I did was enter on the phone dial pad ##72786# that'll reactivate. Hope this helps
