Hello! I've been struggling with this problem for two months already. Basically, when I turn on WiFi tethering it works fine. I get high-speed transfers and well signal strength. However, hotspot becomes unresponsive shortly after screen turns off. Not a single ping can be received. I also noticed, that signal rate drops drastically shortly before it disconnects completely.
This issue stands to all devices I try to use with my OPO - laptops, smartphones etc.
I've already tried:
setting settings put global tether_dun_required 0 on ADB
changing hotspot WiFi frequency
changing hotspot SSID and password
changing battery mode
disabling battery optimization for "Android System" (sadly no Tethering app were found on the list)
I don't use any kind of battery savers. Nor of my Xposed modules should affect system in such a way. My Oneplus is running the latest CM ZNH2KAS3P0, however this problem had been present on previous ROMs already.
Any tips? Thanks in advance
Maybe....
Wifi -> Advanced Wifi Settings -> Keep Wi-Fi on during sleep ?
It's also set to Always, without effect
Encountered similar issue of WIFI from OPO mobile hotspot keep disconnecting. Troubleshot by putting the same SIM card in other phones where there was no such issue, so OPO is the issue here. Tried many suggestions but don't work, until I went to phone "Settings", then "Network & Internet", and lastly went for "Reset Wi-Fi, mobile & Bluetooth" to find this issue fixed finally!

I have noticed that there have been a few times where WiFi is connected and 4G is connected also. The only remedy is to turn off and on WiFi. When this happens, sometimes I have no data connection (probably cause they are conflicting) but this can't be good for battery.
4G mobile network still connected when Wifi is ON?!
I have this exact same problem! Thing is, mine just started showing this behavior like a day or two ago. It's doing it right now. Both my Wifi and 4G icons appear in the notification bar. The 4G icon isn't showing activity (the download and upload arrows are dimmed), BUT if I go to my "Phone Info" app, and go to Phone Information it shows:
GSM service: In service
GPRS service: Connected
Network Type: HSDPA
Before whenever I was on Wifi only the Wifi icon would show up, and Phone Info would show GPRS Service as : Disconnected, i.e. normal behavior. Now it appears there is a conflict somewhere and the 4G network is showing as connected even when wifi is on.
Now, I did make some changes recently:
1) Temp-rooted and pm disabled a bunch of bloatware - this was like 4 or 5 days ago and I didn't have the problem at all so I'm not sure if it's related.
2) I unchecked Wireless Settings > Mobile Networks > "Enable always on mobile data" - Thought it might save battery when in sleep mode.
I think the problem started after #2. I've since checked that option back on, restarted, airplane mode, battery pull etc., but it's still exhibiting the same behavior. I've never seen this happen on any of my past Android devices (a lot). If I go to the Quick Settings it shoes Mobile Network is OFF but it IS checked. It's really confusing. When you turn Wifi on, Mobile network should disconnect, but according to phone Info, mine is on and I've been getting "network issue, try again" in the Market, and "Network Communication issues" in the Speedtest app so clearly something is being affected.
This has been my ONLY problem with my Sensation thus far, and the fact that it JUST started doing this makes me wonder what I could have done to affect it.
Thoughts?
EDIT: Every once in awhile the 4G icon WILL disappear leaving only Wifi on, and Phone info shows GPRS service: Disconnected, but eventually the 4G/2G icon comes back and Phone info shows GPRS service: Connected, so it keeps trying/turning itself on even though my Wifi is connected. WTF!
i dont have the problem of having both, i have the problem that my wifi seems to like turning itself off now and then. this has only started happening since temp root also
Thanks to Sdobron from the thread I had started, it looks like the My Account/My Device app may be the culprit. You can try killing the tasks/services and see if it helps. I personally just disabled both apps like I disabled all of the other bloatware, rebooted, and it seems to have fixed the problem so far (for the last hour anyway). Now I get only Wifi icon, not both Wifi and 4G, and the GPRS services is "Disconnected" as it should be when Wifi is on.

Hmmm did you disable any apps, and if so, which? Is your Wifi sleep policy set to "Never"?
Hi,
Just wonder if anybody is experiencing the same wifi fallback issue on the SGH-i727?
Basically, the phone doesn't automatically fall back to the previously added wifi network from LTE/4G when the screen is off. To get around that, I'll need to hit the power button once every time I enter the wifi range. When the screen is turned on by hitting the power button, I will see the 4G/LTE being replaced by the wifi icon very quickly. After that, it will then stay connected to the wifi network regardless whether the screen is on or off.
I was able to confirm this issue by monitoring the app traffic before and after I turned on the screen.
Without turning on the screen in the wifi range, the phone will stay on the 4g/LTE network forever even though the previously added wifi network is available.
I have already tried out different routers and it's still the same. SSID broadcast is on. I am thinking if there's a bug with the phone. Note that on my phone, my "Wi-Fi sleep policy" under the advanced menu of the "Wi-Fi settings" is always set to "never". Also, it's a stock ROM, nothing is modified at all.
This issue has never happened on other phones. What you think? Am I missing anything here?
After playing with it more, I noticed that the phone will never do the wifi handshake when the screen is off.
I tried turning off and on the wifi in the Wi-Fi settings. If I turn off the screen quickly before the phone gets connected to the wifi network again, it *will* remain unconnected until the screen is turned on again. =(
Did you go into the advanced wifi settings and change the wifi sleep policy?
Sent from my SAMSUNG-SGH-I727 using XDA App
No, I didn't. I've never touched that setting. The "Wi-Fi sleep policy" is always set to "never".
My phone can still be connected to wifi when the screen is off, so it doesn't seem related to the "Wi-Fi sleep policy". The problem is only that it won't do any wifi connection handshake during screen-off.
Am I the only one having this issue? I guess that's more of a software issue rather than a hardware issue?
Have you tried the AT&T wifi app? It automatically turns off and on wifi as needed
No, that doesn't help.
Yes, I do realize I'm bringing back a thread from the dead, but...
I just got a Samsung Stratosphere (SCH-i405 -- a CDMA-1X/EVDO/LTE Galaxy S phone) and it does EXACTLY the same thing. It's ironic, on the Stratosphere they added a bit of fun that CONSTANTLY lets you know there's networks (which I had to disable), but it doesn't connect to the wifi networks I do have in there until I turn on the screen I guess that's just how it is; at least it doesn't kill the wifi once it IS connected.
If anyone knows a programmatic way to bypass this, I'd be interested, and I could write up a wifi app to implement the solution. I'm guesisng it's a behavior of the drivers though and would take some custom ROM or something to fix.
You could always try to use tasker for automatically connecting to the wifi using radio antenna or maybe can't remember if possible by identifying certain wifi spot.
So I've had my Nexus 5 for roughly around a month and I hadn't experienced any issues others have had with wifi not connecting until now. My N5 will show im connected to my home wifi with full bars, but going into quick settings shows it to be orange. Suggesting there's no data transfer, I cannot use any internet based apps with wifi. I've tried some suggestions, switching my router off then on, rebooting the phone, turning some settings off in the advanced panel in wifi settings. All have failed.
I was just wondering if anyone else has this problem and if anyone has a fix to it.

There was a thread around here somewhere that suggested turning off your mobile data helped fix this problem, I think it was in the N5 General forums.....here it is:
http://forum.xda-developers.com/showthread.php?t=2550690
Don't know if it'll help or not, just saw your thread and had just looked at the other one, figured I'd toss it out there.
Thanks for the reply, just tried that solution but still no luck.
I have a similar problem except that there are phases of wifi not working.
Sometimes I would have around 20-30 seconds of WiFi not working and there would be no data transfer.
Speeds are still fast when it is working however.
I played a little with only using mobile data and no wifi, and everything worked. (Small sample size however).
Seems like this is a WiFi only issue.
So somehow overnight the wifi has managed to fix itself, will report back if the problem returns.
The issue with the wifi returned unfortunately.

Don't know if you've tried this but change your WiFi frequency band in advanced setting to either "5 GHz only" or "2.4 GHz only," whatever your router uses. Might be worth a try.
Thanks for the help, but I've tried changing some settings in advanced wifi settings but it hasn't worked. Even what you recommended I've tried that before and it didn't work.
wifi issue
Also I have the same issue - Im connected to router by wi-fi, home and work and time by time (5x a day) wifi stops working. Wifi is enabled in settings, but there is no connection. Restart the cellphone helps, but after that, maybe an hour, it appears again.
Issue was in 4.4 and still appers in 4.4.1.
Yet did not found how to solve it.
I have the same issue on my gnex running shiny 4.4, but I also had the same issue on 4.3. Tried the wifi options, nothing worked. Unfortunately, no solution for this device that has to last one more week. The double swipe down and tapping wifi gets the connection back, but it is only a work around.
The N5 connects seamlessly to my home and work wifi. A few days ago, I flashed the hammerhead factory image, TWRP and the 4.4.1 update.

Hey,
I have the same problem with 4.4.2.(factory rom, no root or not unlocked). Sometimes the wifi not works and get orange. I must put airplane mode to fix it. Its annoying.
But as well happens to me:
When I go out from office or home (where I have wifi connections saved in phone) the phone automatically switch to data plan from carrier. But when I come back the phone stays with data and there is not automatic switch to wifi. Sometimes it help to put wifi off or always airplane mode on/off for a while.
I do not know if it is normal behave of android but I would like have automatic switch to wifi.
I tried to change wifi details (changing bands, etc.) but not helped.
Please help. Thank you.
Is custom ROM or kernel will fix it??
For some unknown reason, as soon as I updated my router's firmware, the problem disappeared.
Updated Android 6.0 solved the issue

So I had the unfortunate experience of having my wifi go down while on vacation and for 3 weeks I spent a good chunk of time wiping and reinstalling multiple versions from Cyanogen, Paranoid android and 4.4 - 5.1 to no avail. I just did another factory wipe today and installed the new Android 6.0
The Finger Pointing Game is OVER
Read through 30+ pages of other android users with similar experience and some people send their units back to LG and some even managed getting a new handset. There was never any hardware issues with my unit I just couldn't turn on the WiFi but after the install WiFi works? Guess next time you push a software update to our Phones CHECK YOUR SH*T google and Maybe DON'T Take 3 months to FIX your F*CK Up.
I have a similar issue. Since Lollipop my phone almost never automatically connects to my WiFi anymore. What's wrong?
Got a new S8+ yesterday.
Everything is fine except WIFI, it keeps disconnecting all the time, going on and off, until it finally stops working...
I tried removing all background signal checking and all unnecessary options, and also I did reset it to factory twice, but the problem persisted...
I have my former S7 Edge on the same network without problems...
I am having the same issue. Disconnect then reconnect every few min.
I had one disconnect this morning but it transfered to the 2G instead of the 5G.

Check your network settings; it may be switching between LTE and WiFi to "conserve energy, buy having the strongest connection." I have had that issue in the past with other devices.

Tried that already, but it is completely disabled..
In fact
Nearby Device Scanning is OFF
Wifi Calling is OFF
Location is PHONE ONLY
Smart Network Switch is OFF
Network Notification is OFF
Hotspot 2.0 is OFF
Keep WIFI on during sleep ALWAYS
and it is still happening.....
When I was first provisioning the device at home I was running it off a Ubiquiti AP Pro and kept getting disconnected. I took it off WiFi and ran the setup on 4G LTE only and connected to my WiFi after. I run Google Fiber and did some 5GHZ speedtest and was never less than 600mpbs up and down. Absolutely 0 chance the initial issue is my network at home. I haven't seen it disconnect since the initial setup but that does worry me a bit. I'd wipe the network profile and set back up.
Probably unrelated but I've found that the 5Ghz WIFI strength on my S8 5.8inch is terrible. The 2.4Ghz is fine though. Compared to my Pixel the 5Ghz is on average about 1/3 the connection speed at same range as the pixel and has much lower strength signal (testing with WIFIAnalyzer). If I cup the phone with 2 hands in landscape mode (how I normally watch videos) I often lose my WIFI connection completely from the 5Ghz network here.
Me to having same issue with WiFi disconnect automatically getting irritated from that
How to fix this guys
Had the same problem on mine. Setting the IP address to a Static IP fixed the issue.
Try going to settings, backup and reset, reset network settings. See if that works.

Hi,
I have noticed a strange behaviour using Wifi Calling. When I am away from home, and returning, it takes the phone about 15-20 mins for the wifi calling icon to show up and to be available. If I use airplane mode on/off it works instantly. I have seen this a few times on IOS as well, but seems more frequent on Android. So far tested on Samsung S22U and Sony Xperia 1 IV.
Also, today, while I was in a call, using VoWifi, the call dropped and when I looked immediately on the phone, vowifi icon was gone and it came back in a matter of 10 seconds.
Has anyone faced these issues and was able to narrow down the cause of it? My Wifi network does not have a firewall in place nor am I doing any sort of filtering. Changing between DNS servers makes no difference.
Turn off automatic WiFi network login on your phone and check again if it helped.
Hi, I do not have such option available. You mean wifi auto connect when in range?
Yes, because the phone can switch when the signal from the first router is weakening. (1)
Also, by setting up a manual connection, you can be sure that you are connecting to the router you want to connect to, not just any one. (2)

So you're saying turn those 2 settings off? I just recently ran into this issue with my Wi-Fi conking out intermittently and I'm experiencing 20% battery loss over night. I'm thinking its bad hardware. I just turned off these settings. I'll report back if it helps.
