Model: TL-WN727N
Hardware Version: V4
Firmware Version:



I found a serious problem with my USB TL-WN727N recently.


So, it is all started when I moved to my new apartment. The apartment provides a free wifi connection with close proximity to my room, so the distance should not be a problem. When my PC fired up, I can't find wifi strength signal which usually appears. I tried to use the TP-Link utility tool to connect via the app, I fill the right password but the app always refuses while saying "the password might incorrect". I can assure that the password is correct since my phone and laptop can connect to the wifi smoothly.


Also, the LED on the device blinks every second since I turned on the PC. I have tried some other alternative including reinstalling the driver, restarting PC, and try on a different port. But none of them solve my problem.


I hope anyone could help me here.

What is the operating system of your computer? 


Have you ever tried to forget the network and reconnect to the free wifi? Below is the instruction ( here takes Windows 10 as example)


Are you able to modify the wireless settings of the main router, like wireless channel and channel width? 


If so you can change both to give it a go, for 2.4GHz, use channel 1, 6 or 11, channel width 20Mhz, for 5GHz, use channel 36, 40 or 44, and channel width 40MHz.


Good day.
