S21 Ultra Wi-Fi problem (Connected without internet)

Hello.

I have a problem with my S21 ultra when I connect to the internet via any Wifi. No matter what I try it always starts to lag and after few minutes it shows "Connected without internet" and an exclamation mark on the wifi sign. I tried with different routers, with different settings, at different places with different ISP, the problem presists. I read somewhere that I could try clearing the cache and forgetting and reconnecting back to the same wifi networks, it did not help. I even tried turning my phone OFF and ON again million times. The only thing that helps is turning wifi off and then on. But after few minutes the problem comes back. Is this a software problem and it will be fixed or is it something hardware and I should send it back for repairs?

Phone S21 Ultra 5G
Model number: SM-G998B/DS

It's related to using the 120Mhz channel on your router, I'd imagine it's software related on the phone.

I have the same model number with the same problem. The problem not always happening, just occasionally, but it still annoying.

No custom DNS set? (for ads filtering maybe) Check that setting too.
