https://us.community.samsung.com/t5/Galaxy-S21/Poor-WiFi-Range/m-p/1691802#M4732 Are you using Private DNS?<BR /><BR />If you can, set Fixed Allocation for the phone in the router's settings. Then turn off Wifi on the phone, wait 15 seconds, then turn it back on.<BR />Test again<BR /><BR />If it persists, I'd call Samsung - maybe the phone has an antenna issue.<BR /><BR />One last to thing ... have you tried a completely different Wifi network away from your home?
