    USB wifi connection is suddenly off

    Ubuntu 16.04 LTS running in a desktop PC.

    I'm using a TP-LINK TL-WN722N.

    It works ok until for unknown reasons there is no more wifi signal. Needless to say alll the other devices, cell phones and a couple of notebooks (running Windows) have wifi.

    Sometimes unplugging un plugging back the USB stick works, sometimes I have to restart Ubuntu. And sometimes it will not get any wifi signal after restarting.

    It is working at this moment but who knows in the next minutes.

    Is there something I can do to fix this issue?

    Thanks.

    Please run the wireless script from the sticky thread and show the outputs. Does LAN work?

    What do you mean by the sticky thread? Should I do it while it is working ok or once it failed to connect?
