Connection loss while dual band activated at the same time.
I've bought myself the Archer C20 2 months now. been enjoying its features. but whenever I've kept using both 2.4Ghz band and 5Ghz band at the same time I've lost connection on only the 2.4Ghz band. i lose connection, i turn off WiFi from my phone and then turn it on again just to find my 2.4Ghz band nowhere. the 5ghz band still shows up but for a couple of seconds the 2.4Ghz disappears and when it comes back, the internet connection is lost and i have to restart the router to get the internet back. last night it got to the point where I've had to restart it 12 times in an hour. ive contacted my dealer to get a replacement considering i have a year full of replacement warranty but they've told me to wait till lockdown goes down in my area. This is very harassing to me. Can i get help somehow?
