Archer T6E Network Card getting extremely slow wifi speed
I've been connecting to my 5Ghz network at home completely fine but suddenly the speed of the network has decreased on my PC from 100+mbps to about 10. I know its not the error of the router since the network is working completely fine on other devices like my laptop and phones. Even the 2.4Ghz network has slowed down. I've tried everything from changing the channels of the network. When I open the device properties on my PC there is no option to change to 802.11ac or no option to select the 5Ghz network. Does anyone have a solution for this?
