Tplink TL-WN722N sudden speed drop
My recently brought TPlink tl-wn722n 2.4ghz wifi adapter suddenly dops bandwidth from 10Mbps to soo much lower even like 300Kbps .
But at this time I am only wifi user . Then i checked my net speed using LAN port of my router but its working fine . I am approximate 15 feet away from my router .
But facing this problem sometimes , even from 2 miniutes to 5 miniutes its work well .
I changed my pc usb port for solution but no solution. Can anyone tell what causes this issue and the way to solve it .
My router is tplink archer c20 v5 US model with latest firmware .
