My pc gets around 30 mbps on wifi. All the other devices on the same 5ghz band get 110 mbps . I have even taken the test on my phone in the same position as my pc to see if the position is the problem, but the speed on my phone is still 110 mbps. I am using the TP link archer t2u and have all my drivers completely updated, does anyone have any idea as to why its so much slower?
