I have a TP-Link wifi usb adapter (model: TP-WN725N) which I use with a low end HP laptop (unknown model, four years old). The OS of the laptop is Debian 9.4. I used to plug the wi-fi adapter to the first left side usb slot of the laptop, and it works fine. Today I happen to plug the adapter on a different usb slot and noticed that I was unable to connect to the wireless network I've always used (WPA2 authentication method). Every time I got the following message in my logs:
R8188EU: sta recv deauth reason code(15)
Searching the Internet and looking at this question, it could be a driver problem or a cheap hardware issue, but why it works in the other slot then? What am I missing?
