I recently bought Samsung S5 G900F from a friend which updated it to latest lolipop 5.0 software, and after that wifi stoped working.
It was never rooted or etc. When i try to turn on wi fi i press button for turning on freezes and it doesn't show any wifi network. By my friends words it started after updating to lolipop. First i downloaded and flashed two 4.4.2 from sammobile and i there's no difference at all.... Second thing i found thread with latest modem on xda and nothing at all.
The only thing that helps for short while is from unkown reasons when i switch SIM cards it starts working but speeds are 200,300kb/s and signal is very low. And from some secret code went to wifi settings and turned off battery saving mode, it helped to now more often it works but for short while and slow speeds.
I don't have any ideas, what to do with it all sings show that it is software issue. Thanks in advance on replies

Hi all,

Hmmmm. I think it was with the 4-10 version that I had the issue, and it may have been resolved with the 4-14 version. I just installed the 4-17 version, but haven't checked if the issue returned. I would try upgrading Chroma, if that is what you are still running.

I'm going to reinstall all apps in my n4 for now with stock ROM. I installed all updates from 4.2.2 image factory with OTA's up to 5.1, to night I still with wifi connection, if tomorrow the issue persists, I will install chroma again.
I got this problem too. I was running chroma, Cm12 and now euphoria and problem is still here. Full wipe doesn't work. In addition to the problems with reconnection I have also huge problem with msm_hsic_host wakelock and I think both problems are related to each other. I'll try different kernels, maybe it will work.

I installed stock kernel, and franco kernel. Same result.
My wife has Installed OTA yesterday and remains in wifi all night, today all works fine in her Nexus 4. In my Nexus 4 don't work.
Differences:
Wife: N4 8GB with simyo carrier
Me: N4 16GB with tuenti carrier
Any Ideas?
It seems that the problem occurs only when when you leave the WiFi area, and the phone loses its range. Its not switching connection. When you are connected to wifi and you try to turn it off manually (quick settings etc), it will switch to mobile data connection without problems.

is not it, when I spend three hours on wifi, manual transmission does not work. I put the SIM of another carrier works. Is an error with this SIM and this version of Android.
Hi gruncho,
I have exactly the same problem, also with a Nexus 4 from day 1 after installing 5.1. Mine has been installed OTA, having previously 5.0.1. My carrier is pepephone (now using Movistar) which I think is the same as tuenti, the one you have.
I reconnect without problems by changing between 2G / 3G or by selecting Airplane Mode On / Off.
If anyone knows a less manual solution or something I could try please tell.
Thanks a lot
Same issue here on stock 5.1, only reboot helps. Airplane mode, switching radio off, switching cellular data off and on doesn't help.
Can anyone provide some information how to fix this? Would be very grateful.
I flashed chroma rom 4-21. It is based on Android 5.1.1. The issue is solved on this version. I will use this rom until stock 5.1.1 launch.

If you have the phone rooted, you can install Trigger and create a task that activate airplane mode and deactivate that in a few seconds when you leave any wifi network. I tried this, but in my case, with an android wear device, the watch disconnects every time I leave my home or job wifi.
Hi,
Keeping my fingers crossed for the problem to be solved for everyone in 5.1.1
I thought about creating a task in Tasker that activated airplane mode and deactivated it in a few seconds later after leaving a wifi, but my experience with Tasker is almost null.
I found an application which seems to be working for me. Its name is WifiFixerFree and what it does is trigger a mobile connection for a few seconds, while still connected to wifi.
You can configure the connection interval. I have it set for every 15 minutes and it doesn't seen to drain a lot of battery. By default it shows a lot of notifications, but you can disable all them in one of the configuration screens.
Cannot yet post external links, but the application is in Google Play so it is easy to find from that name.
I installed the application yesterday and the problem has not repeated itself.

When you enter the app, check "Use auto reconnect" and set a trigger interval of N minutes (I wrote 15).
Press the button "Configure notifications" and uncheck the first option: "Show events in notification bar"
I just did that and since then (yesterday afternoon) I have had no more problems of losing the mobile data connection. During the last weekend and on Friday I had those problems every time I left home / work because the phone lost the wifi and so I lost the mobile data.

Thanks so much, tomorrow I will try this.
Today after flashing the kernel that come with chroma rom again, seems works. :good::good::good:
Same issue here, but I came from a Nexus 4 5.0.1 with LTE enabled.
The problem ocurrs when changing to data after too many hours in Wi-Fi connection (turning Wi-Fi off or leaving the Wi-Fi area).
I installed OTA Android 5.1, then the problem started.
I tried to install stock Android 5.1 factory image (with full wipe), but the problem still persist.
I executed the nexus-4-lte-enabler-v2.12-2.13-UNINSTALLER.zip thinking it's a related issue, but the problem still persists.
Waiting for Android 5.1.1...
I have Pepephone (Movistar) and I'm still using the manual workaround of turning airplane mode on/off or switching some data network setting to regain data connection.
Can anyone provide some information how to fix this?
Thanks a lot.

You can install Wifi fixer free from play store. This app has resolved the issue... Until google do something
My brother gave me his old Galaxy S4 E330K. Wifi Bluetooth doesnt work. What I found out is he flashed it with a 5.0.1 Black edition firmware of e330k. I tried flashing it with 4.4.2. Wifi and bluetooth still doesnt work. And whats confusing is the wallpapers are for s4 black edition but the rom i flashed was not a black edition one. Is this wifi and bt already a hardware issue?
Sometimes when a ROM is installed you need to run the "wiping" processes 3 times before you get install a different ROM.
Or flash the rom twice to make sure that partitions have been overwritten.
Or, your wifi chipset might have been burnt. This is what happened to me about 3-4 weeks ago. One day I tried to send some files via BT. BT turned on, but could see no devices at all. A couple of minutes later, the wifi went the same way. Turned on but I couldn't see any available networks. Another couple of minutes later, neither wifi nor BT didn't turn on anymore.
Opened the device and saw the chipset burnt
I read similar stories the same time I experienced these problems; I think for a lot of people S4 is starting to break.
Try to find out if it's a hardware problem or a flash problem.
Cheers!
Hi,
I just received the Oreo update for my S8 and everything seemed fine from the start. It didnt take long though when
I noticed that the WiFi was acting weird. Even though I had great connection to my modem, my WiFi performance
was extremely poor. The two arrows beside the WiFi logo in the status bar only showed upload and no download when I
tried to open a website. I tried forgeting the network but it only seemed to work momentarily. So I rebooted my modem and
hoped that it would solve the problem. Rebooting the modem only worked momentarily too. I will be checking later if this issue
continues with other WiFi networks.
Has anyone else experienced this?
Same problem with My S8 after Oreo. Occasionally the !-mark next to wifi-symbol and the connecton is lost. By restarting the wifi-router or renewing the wifi connection from the phone fixes this for some time, until it happens again.
This fixed it for me
Mine was doing the same but noticed I could stay connected to a older router I use as an extender so changed my wifi security on my main router from wpa2-aes to the older wpa and it's been fine ever since stays connected on 2.4 and 5 now
Is there a fix for this yet? I just downloaded the newest update they rolled out today, 4/3/2018 and I still cannot send email if I am connected to my wifi. It tells me "couldn't send" and it sits there until I turn off my wifi and use my data. This is ridiculous. My wifi connection is fine. I should not have to turn off wifi every time I want to send an email. So frustrated. Why roll out another update so quickly if not to fix the issues the March update caused????
I am also a an S8 user and noticed my wifi dropping connections throughout the day and reconnecting. This has occurred ever since Oreo update. I have tried all the possible fixes and none of them seem to work. I have sent my phone to Samsung for a repair and they have useless approved centres that lie about fixing the phone. I have sent it back. Lets see what happens. Worst case scenario I will have to install Nougat as it was working fine on this version.
Same here ! =(
Same problem
Sporadic exclamation mark on the WiFi icon
and poor performance .
Opened another thread on too many open ports.
Used sockstat and too many ports are listening.
Me too
(ROM France : XEF)
Did you guys notice this after the Oreo update or on Nougat as well?
I’m having this problem since the Oreo update too. I have to turn the WiFi off and on several times a day to fix it. When attempting to use WiFi, no pages etc will load and then eventually a ! Symbol appears next to the WiFi icon. Only fix is to turn WiFi on and off. It’s very annoying!
Exact same issue. Started occurring right after oreo update
Have you guys complained to Samsung about this? as making noise to them will rectify your faults eventually.
Same here, WiFi unreliable since Oreo. I need to restart the network to make a WiFi call and that isn't always a reliable fix. I started a chat with T-Mob on FB and gave up. They're clueless. Samsung S8+
Hello same issu, I'm from France an online the forum in France an Germany many people have this problem.
I read somewhere to delete the wireless connection from your device and then re-add. I'm not ready to say it fixed things but the WiFi does seem more stable.
UPDATE - Sorry to say there are still issues. Oh well, it gave me hope for a brief moment!
Go to settings- General management- Reset- Reset network settings- Then confirm and restart the phone. After re add your wifi networks. That fixed it for me
Update: It turned out that it didn't work for me... it looks like i may have to try and factory reset as it feels like i have tried everything else :crying:

T-Mobile just had be clear the cache from the "boot level" menus. Let me see if that fixes anything before trying yet something further. THANKS!
PS - clearing the cache did fix the problem I was having with the TX Lottery app. After the OREO update it would no longer scan the ticket barcodes. It's working again!
