My exact experience as well with both phones.
Mine had issues here and then when I had the Pixel 7 Pro.
I now got a Pixel 8 Pro. Happy to say, no more issues.
I think it is either the software or the built in VPN been messing it up.
Android is like Windows. Sometimes it just PITA to fix, could be cache, corrupted files, leftover junks, etc etc.
Also I used to have Google Fi VPN, it sometimes mess up the wireless connection. I now use Pixel 8's Google One VPN, it is smart enough to leave Wireless android auto alone.
