Intermittent DNS Errors and WiFi Issues

I have to admit guys I bought 2 RBK852 a few months ago and it's been nothing but junk, constant DNS issues even when using cloud flare or Google it's still an issue, the main issue is WiFi drops, all devices are still connected but just no internet at all only off and on of the WiFi does it come back alive, after 4 months I've had enough, I've popped back in my mesh zyxel multi x and I'm back to bullet proof. I initially thought it was Apple devices but my PS5 right near a possible win on Apex legends WiFi dropped. Enough was enough.... all hardwired items are fine other than sporadic DNS issues no webpage for an instant then it refreshes...

very poor NETGEAR I'm going to create a ticket and try get these swapped but I guess it's firmware or poor development...

after reading 11 pages of people looking at logs telnetting etc honestly this thing should work, the Zyxels I have just work never fail I just wanted wifi6... 

does anybody get this issue in access point mode? I've not tried that or is it purely as a modem it's doing it. And why NETGEAR did dns with some proxy thing out the box daft...if I wanted a proxy I'd have a business and zscaler
