Archer T4E Ping spike and slow speeds
I bought an Archer T4E a week ago and I have experienced constant ping spike and slow network even on 5ghz, like my internet connection is of 300mbps but while connected to WiFi this card only provides 150mbps speed and constant ping spikes to 5000+ms(with full connection strength), I've looked upon multiple threads before posting this and tried all the "T4E.zip" drivers but nothing seem to work. My network performs great on my phone and other devices from the same/ further range with no ping problem. please give me a fix asap as i am tired of this issue and tried way to many drivers to fix but nothing seems to work
