Galaxy S8 Wifi Issues

[SamsungAl]

Have you tried a hard reset on the device? I would recommend saving all your important information before you do so. If that doesn't work we can have you send in the device for service.

Good grief Sebas, don't you think we haven't tried that?

For the 1000th time, this is a Samsung software defect. We don't need to send our phones in 'for a service'!!

WE NEED YOU TO MAKE THE EFFORT TO REPRODUCE THE PROBLEM AND FIX IT!!!!

Hi guys,

I think I've found a way to solve the problem temporarily

In my case, when I switch from 3G/4G connection to Wi-Fi, Samsung Cloud and Samsung Connect services will start. You can check this by going on Developer Option -> Running Services

In order to resolve the problem you need to

- Open settings

- click on Application

- Serch for Samsung Cloud ad Samsung Connect app 

- Click on button Force Stop

I hope that this "solution" will help someone and will help Samsung to resolve the issue

Jesus Christ. Can you guys make an app that will valueca look for the wifi access them see if you can pinpoint it that way? We have been dealing with this issue since day 1. I have the Google onhub and everything else on the router working .I even locked the IP address of the device and still is same issue .I'm tired of thet issue and may consider a different brand next phone purchase of this is the customer service I can expect for something that is a software issue from your devices .

I had the same problem but i think i found a solution.

Type    *#*#526#*#*     in your keypad scroll down to WLAN FIRMWARE DUMP MODE and turn it off than click on WLAN ADVANCED DEBUG and click on DISCONNECTION SYSDUMP and press OK.

When you did this scroll up to DELETE DUMPSTATE and press ok. Then click on exit at the bottom.

When you done all of this type *#2663# in your Keypad and press on REFRESH WIFI VERSION.

Yor phone should automatically reboot and the disconnection problem should be fixed.

I hope it works for you aswell.

Hi

I have a Tab S3 wifi Android 8.0.0 Oreo and have the same issue as you S8/9 owners. WiFi stops working, exclamation mark appears and turning wifi off then on seems the only fix. Tried much the same fixes, factory resets etc but still the problem persists.

I've scoured the net and it feels as though I'm the only Tab S3 owner with the problem so sorry to intrude into your forum. 

For Samsungwhoever

Model SM-T820

Build R16NW.T820XXU1BRE2 (no baseband number)

Carrier n/a

Something that seems to have improved the problem is crippling the Smart Things  app as much as possible. (Can't disable built in apps (bloat) unfortunately)  But the app always seems to re-enable itself after a while so can't be sure.

Is your date and time as well as time zone set to manual or automatic? 

[userDaveB]

Automatic date and time for my tabS3. I can't find an automatic time zone option.

@userDaveB

Is it just your home WiFi or any public WiFi as well?
