Solved Samsung Galaxy S8 Drops Wi-Fi Connection

The #Samsung #Galaxy #S8 is a flagship phone released last year that offers several new features when compared to the company’s previous flagship models. The phone now sports a larger 5.8 inch Super AMOLED display while retaining almost the same body size as the S7. This is made possible due to the removal of the physical home button. Its use of the Snapdragon 835 / Exynos 8895 processor allows it to run any app smoothly. Although this is a solid performing phone there are instances when certain issues can occur which we will be addressing today. In this latest installment of our troubleshooting series we will tackle the Galaxy S8 drops Wi-Fi connection issue and other related problems.

S8 Drops Wi-Fi Connection

Problem: Ok, this one is crazy pants. . But my Samsung (two S8 phones and a tablet) products suddenly stopped working correctly with my network. All other devices work perfectly with my home network, but the Samsungs take a VERY long time to establish connection with the internet server. They connect to the WIFI fine, but not the server. And they drop that server connection a lot. But these Samsung devices work perfectly with other networks where I have taken them to test if the phones are suddenly defective. They are not. They work fine elsewhere. But, as I said, my home network that works so poorly all of sudden with my Samsungs (after two years of working perfectly) is also not defective. That home network still works fine with my other devices from Sony, Apple and HP.

What it is not:

-a problem that can be solved by rebooting or refreshing or clearing caches. All such things have been tried multiple times.

-a defective modem or router (two different modems and three routers (two Ubees and a brand new Sagecom have been tried, and the three Samsung products have the same issue, but none of the other devices have any issues with any of the routers)

-all firmware, software, apps are up to date

-I tried removing and rolling back all apps to before the time the problem began (a week ago), and it persisted

-I factory reset the tablet, and the problem persisted (so I’m not factory resetting the two phones just to try it).

-I set DHCP to static, and the problem persisted

-it happens on both 2.4 and 5 Ghz

-I’ve changed all SSID’s and passwords multiple times to rule out hacking

-No malware is present that any program can find

-No interference is present

-I’ve tried all channels

Again, the three devices worked perfectly fine with my home network for two years, and then one day they suddenly started taking forever to connect to the internet servers. For all I can tell, they are connecting to the WiFi just fine, and they never lose the WiFi. It’s the internet server they are having trouble connecting to. Once they connect, there is no issue with speed. They operate at 100-120 mb/s just like they should. But they then drop that connection frequently, and they must reacquire it, which again takes forever. If they never connected, that would make sense. But connecting, working fine, then dropping is crazy. If it was one phone, then that makes sense. But two phones and a tablet? If it was all devices from all manufacturers, then that makes sense. But it’s only the three Samsung products. No Samsung updates have run through any of the three devices in months. The last S8 update was months ago, and the last update for the tablet was years ago. And again, no apps are causing this, as I uninstalled everything and it persisted. And the tablet barely has any apps. Finally, let me repeat that the phones work perfectly with the exact same model of routers and Spectrum servers at another location (a store down the street). They only have this issue at my home network. But if my home network were messed up, then why do the Apple, HP, Sony and Chromebook devices all work perfectly? I am cross-eyed and confused. Please help me.

Solution: This is a tricky issue. The best thing that you can do right now is to check if the problem still occurs when the phone is started in Safe Mode. In case it doesn’t then you might have installed an app that is causing this problem. Find out what app this is and uninstall it. You should also consider doing a factory reset on your phone. Make sure to backup your phone data before doing the reset. Once the reset is complete immediately check if the issue still occurs. In case it does then this could be caused by a router issue. You need to check your router settings as it might be affecting the way your phone connects to the network.

S8 Wi-Fi Intermittently Disconnects After Oreo Update

Problem: After Oreo update Wi-Fi intermittently disconnects on my S8 while other devices function without any glitch. Wi-Fi connection symbol shows exclamation mark. After a while the connection automatically is back to normal. Cache clearance, reset all tried but issue remains same.

Solution: If this issue occurred after a software update then this is most likely caused by some form of old software data that has not been completely removed during the update process. The best thing that you can do right now is to backup your phone data then do a factory reset. Once the reset is complete try to check if the issue still occurs.
