My PC, Galaxy Tablet, old Razer phone 2, and Xbox are not having any issues with the WiFi nor are anyone else's devices either.
I have had this issue for 5 months, none of the Samsung OTA updates have fixed it.
Every other device on the network has no issue. Found no solution sadly.
Tried setting static IP, resetting network settings on the phone, updating the router firmware etc.
Issue seems to only happen on my home network though, work wifi is fine. Make of that what you will.
- My device is a S22+, not ultra
- My router is the Home Hub X000 (4000?) from Bell (Rebranded Sagemcom Router)
I'm having the same slowdown issues running to an Adtran 834v6 router using Wifi6. My connection will be perfect with 300+ Mbps download, then it will go to snail-pace speeds on 2Mb or less. Often, it changes to being connected without internet. Previously, I found that changing the bandwidth settings to an HT or VHT (turning off Wifi6) fixed the problem. However, I've recently upgraded to the PlumeOS in the router. Plume exercises full control and won't allow the manual bandwidth changes so I'm back to the slowdowns. All I have to turn is turn off wifi on my phone, then turn it right back on and it works perfectly...for a while.
