Model: TL-WN722N  
Hardware Version: V3
Firmware Version: 190409

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 .

@Kathy_Z Thanks for reply.

 

I am sure in now that it was not wireless adapter problem . but it was because my tplink archer c20 v5 US . Because there is too many interference and channel over lapping in 2.4ghz band such as almost 15 to 16  nearby router detected by my Tplink TL-WN722N adapter. I contacted service center of Tplink in Bangladesh, they suggested me to change router channel manually to a less congested channel and I do it. From then there is no problem
