Sprint SPH-L720
Currently running Optimized CM 12.1 with OD2 modem, but the problem persists regardless of ROM or modem. I have tried NG2 modem and I have tried Stock 5.0.2 ROM as well as GPE and nightly CM 12.1.
The symptoms are these: when connected to any wifi 2.4ghz or 5ghz, secure or public, during heavy wifi activity (large downloads/streaming music, etc) my wifi connection with just stop transmitting/receiving. It will appear still connected but no data will transfer. If left in this state for long, it will disconnect and all known wifi APs will show "wifi connectivity failed". This also happens nightly when the phone is left idle over night. I wake up to no wifi connection and all known APs showing the connection failed error. I can tap any connection and it will reconnect just fine. I can also cycle wifi power and it will reconnect just fine.
I suspect this is a faulty Wifi chip considering I have tried varying everything else possible. For now I'm going to see if I can get by with a tasker profile that resets wifi power periodically when connected, but I still have the ability to RMA if that doesn't solve the problem satisfactorily. I just wanted to see if anyone else had experienced this particular issue or if anyone had any other ideas. I have found a few other threads for this phone with wifi issues but none of them had the same exact symptoms and none of the fixes described solved the problem thus far.
Thanks

Ok so tis is my problem. the Wifi connects fine. i use it for 10 minutes...20 minutes..it works.. then suddenly.. it stops working?
I go to comm manager the Signal quality is full or 3/4 full (dependent on location). it stays connected... the tx rate is 54Mbps and the Rx Rate jumps between 1-54Mbps.. My network is not security protected but no one uses it except me and my computer.
Im using messeneger then it says " messenger trying to reconnect blah blah) then i go to opera and it stopped working too...but its still connected, the signal strength is still strong?
Whats going on?!
My router is a Netgear DG834GT.. I have put my xperia's mac address on the allowed list as well.. i just dont get it?
i have to disconnect and reconnect to get it working..then it lasts another 5 minutes and dies again? Sometimes when i reconnect it still doesnt work so i have to turn off wifi and turn it on 2 or 3 times?
You are not alone, my friend. That's exactly what happened to me, except mine is Belkin.
Someone here (sorry I can't remember) suggest turning off bluetooth solved the problem.
i would try upgrading the firmware of the router it solves many incompatability issues for many people
sometimes my linksys drops data connection so the wifi signal is just a pin
and only fix is to unplug the router for 10sec and replug it
seems to be common that wifi act up at least see people complain in many many forums for wifi able devices
bluetooth is not on at all... Also every other wifi device will connect just fine? why would it work then just stop?
I have no idear only knows that what i wrote fix it in many cases for many people
i have wifi on even in standby tweaked...did you guys tweak anything? like auto off or anything?
nop i just use wpa AES
but as i said i update my wifi router with the latests firmware when
ever linksys updated it and believe me they updated it often
is anyone facing this problem or faced it before then fixed it?
if it's not your router as Rudegar suggests (one way to test, try over a different wifi elsewhere) then I wonder if your wifi is powering down for some reason?
Hey guys...having the same problem. Firstly I had trouble connecting to Wifi with the Xperia...then I updated the router firmware...now I can connect to Wifi but it does nothing, I cannot surf the net, I cannot connect to Skype I cannot connect to Windows live, cannot check my mail, etc...
Any ideas? Bluetooth etc not on at all...
This issue really bothers me a lot after I upgrade my Atrix to Gingerbread: when I turn on the wifi, it takes up to 2 minutes for the phone to connect to a wifi hotspot. During that connecting time, in the phone's wifi connection settings, it's either showing 'scanning' or 'obtaining ip address' but with an empty wifi network list. It seems like the wifi chip is still initializing itself or something. This problem doesn't happen all the time. About 1 in 10 times, it can connect to the same wifi hotspot instantaneously. And I am pretty sure it's not the problem of the wifi hotspots because I used them before with the same phone + froyo and there was zero problem at then.
Has anyone seen similar problem like this?
Forgot to mention that I have done the factory reset several times and the problem never goes away.
This started Feb 3rd or 4th. The phone will connect to the wifi network, with a good signal. It will then re-scan every 5 seconds or so. This is causing all sorts of data transfer issues from downloads freezing to apps losing connectivity while running.
I am running on Verizon.

I am now running Android 5.0 but had NOT updated to 5.0 when this problem started.
I scoured google a bit and found an ATT forum that is essentially reporting what I am.
forums.att.com/t5/Samsung-Discussion-Support/Samsung-Galaxy-S5-Wi-Fi-Connectivity-Problems-After-4-4-4-Update/td-p/4190704
All other devices on the network are operating without issue - phones and computers - as was mine until now.
I have power cycled everything.
I have checked the routers settings.
The phone has been power cycled several times.
The phone has had every wifi setting that would be causing this scanning, that I know, disabled.
The following are off in Wifi > Advanced:
Wifi notifications
Passpoint
Always allow scanning
Smart network switch
I then, after the above, updated to Android 5.0. The issue still persists. Help me please.
My device does this, too. Cant say I have ever really noticed, I dont know if it has always done this or not.
I am not experiencing any issues like you describe.
Now that I think about it, I think it will always scan at a set interval when you enter the Wifi settings. It assumes you are looking for a network to connect to. I doubt its scanning when you are not in that setting.
I had this problem the other day. I went to wifi settings and had it forget the network and then rebooted and reconnected to my wifi network and it seems to have resolved the issue. others have just switched airplane mode on and off and this fixed it. good luck
For the last week or two I have been unable to connect my phone to wifi networks.
At first the problem would be that I was getting disconnected from any wifi network I joined, now I can't connect at all.
The wifi networks page sometimes (not always) does not detect a strong network even if I am standing a few feet away and the phone has previously connected and other APs are connected and working like my pc
If I try to connect then I get the "Connecting" status followed by "Saved,secured"
I have searched the internet looking for a fix to this and tried wiping the cache partition, forgetting the network, airplane mode toggling on and off, apps that wipe the known network list and some others including lastly a factory reset on the phone but nothing seems to remedy the issue.
From the wifi router I have tried using an unencrypted (open) connection
Now I think I may also be having problems with the bluetooth connecting in the car but I haven't had a chance to really investigate that one yet and it may or may not be related to the last factory reset.
My phone is not rooted.
Build no. LRX21T.G870AUCU2B0F3
kernel3.4.0-4443965

Can anyone offer any assistance to my current issue ?

I have just confirmed that the Bluetooth in my car is not detecting my phone when it scans (the phone bt is switch on and the visible box being checked) so that's both radios with similar issues.

Im having same issue with wifi... sm-g900r4
I just stumbled on a clue, while using an app called 'wifi cleaner' there is a feature allowing you connect to wifi networks within the app. I type in the password, authenticating is shown on the screen followed by "incorrect password".
I know the password to be correct..
Mmm

I was wondering if you ever got this issue fixed?
I thought I had but the problem comes back in a different way.
Sometimes wifi connects but only connects at 5 mbps.
Now wifi will not turn on at all. ( radio button is greyed in settings)
I did find a thread on xda where some Motorola users were having the wifi off issue and it was due to a missing system file which could be replaced on a rooted device. However I don't have root on my s5 g870a and it's not likely I can get it.
Hi there,
I have my S8 Exynox version for more than one week and I am facing some strange issues that I cannot explain and I have never experienced them with my previous phones.
I have WiFi router (2.4GHz/5GHz) running OpenWRT and S8 is disconnecting or keeping connected but losing internet access. Many times when I unlock the phone I can see that it is not connected to WiFi and just connecting or there is a message "Connected to XXXX" indicated that the connection was somehow re-initiated. It seems to be more stable if I remove 5GHz network connection but still not reliable.
This is even more strange. When I enable WiFi on S8 and let it connect I am facing network connection dropouts on my LAN not only on WiFi but even on cable. I am listening network radio and the sound disappears randomly and the issue is gone if I disable WiFi on S8. Sometimes I even have to restart the router.
Settings changes randomly. I was navigating with Waze and there was no speed indication. I stopped and found out that it was disabled in settings although it was enabled my previous drive. And another time LTE was suddenly disabled. There was 3G/2G selected in Connection -> Mobile network -> Mode.
I am using Dropsync to synchronize several Dropbox folders with my phone. One of them is synchronized to Share folder in local storage. Yesterday I found out that there is some sync problem in Dropsync and it turned out that Share folder is not existing. Some process has obviously deleted that folder. Could it be that I run optimization in device maintenance?
I am using Nova launcher with Morena icon theme. I have selected some icon for Samsung calendar to have is consistent with the icon theme but it randomly changes to stock icon during the night.
It forgot BT pairing with my Garmin Forerunner. I had to pair them again.
I have enabled volume sync when I connected my JayBird earbuds for the first time but it was disabled again few days ago.
Does anybody else have issues like this?
Experienced the WiFi issues in the beginning too, it doesn't kill my ping any more at least not majorly and it seems to have stopped not being able to connect to my router properly. Can't say anything about the rest.
And how did you solve the WiFi issue?

I didn't, it resolved with time, it did seem to stop after rebooting my router one last time but I doubt that's it as I already did that once and the issue happened again.
