I posted this to the TP-Link forum. Have not got a response yet, but i though I might as well post it here to be a little more specific and maybe you can help me after all. Anyways here it is:
I Just installed the Archer T6E in my new desktop. I installed the drivers as it's supposed, but the internet is super slow. I'm getting between 100 and 300 kbps on this desktop while I get 50 - 100 Mbps (note the M) on my macbook while sitting at the same desk. The weird thing is, when I check the reception in the windows wifi status dialog, it says it receives between 20 and 50 mpbs (which is also not that much but at least like 10 times better. But when I do a speed check it only goes up to 300 kbps. When I run network diagnostics I finds this problem: "Your computer appears to be correctly configured but the device or resource (DNS Server) is not responding.
I hope anybody can help me out with this.
