ASUS ROG 3 80211 wireless / 5G cell incredibly slow

i just successfully flashed to the ASUS ROG 3 phone, everything seems all right, however im noticing 80211 wireless / cellular internet connectivity is extremely slow. like an hour to download a simple small app from the app lounge. This is a wifi6 based 5G phone also.

Hi Dingo,
plz test if download is better when you switch Advanced Privacy OFF. Then try again…

Ive since reflashed the device, now wireless seems more stable yet, still sketchy, most specifically now the mail app, and sometimes other apps state no internet when wifi is on, and mail app is continually telling me Authentication failed for gmail.
