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.
