Samsung S8 slows down At & T WiFi

I have a samsung S8 which when I connect to an At & T Wifi at home, starts to slow down internet on all devices connected to this network. The speed drops from an average 14 Mbps to 1 Mbps. I also see that the AT & T 4G is slow on this device. I already did a scan for malwares and monitored data usage on the phone to see if some process is blocking all the bandwidth and I found no issues. Any idea on how this can be solved?

On January 27th my S7 edge received a new software update and right after installing it my phone started taking up all of the internet’s bandwidth to the point where everything else is getting 0.2mb/s or even worse. I’ve done multiple test to see whether or not it was my phone and anytime I would disconnect it from the WiFi everything would improve and vise Versa.

I did check upload/download stats on my phone when I connect it on to the WiFi network. But I do not see any major upload/download happening and I am still wondering why there is a slow down on the entire network just immediately after my phone is connected on to the WiFi.

Hello @kosdfh,

Thank you for bringing this question to the Community! I definitely understand the concern with the device using up a large portion of the wireless bandwidth. I would be more than happy to help with this!

A few things can impact how much space is consumed by your device on the network. Typically internal settings, type of wireless internet, and number of devices connected can all impact speeds for the devices connected.

We’ll first want to make sure device settings are properly adjusted and the device has the best opportunity to connect to the network. You can access our Troubleshoot & Resolve Tool to complete a specialized flow for your device and issue. For further concerns, please feel free to contact us back for more in-depth troubleshooting.

I hope this helps! Have a wonderful day!

I was finally able to relate what had happened in this case. My AT&T contract phone was  moved from 4G to 2G because the group plan I was in, had exhausted the monthly data limit. But connecting my phone to AT&T WiFi also caused the modem bandwidth to shrink which must be a bug in the system. When my phone switched back to 4G from 2G, the WiFi also worked just fine. Can someone from AT&T look at this problem and correct it as soon as possible?
