My son's desktop PC has happily connected via a TP-Link adapter to our home PC - maximum signal strength, no issues.
Today, I disconnected the adapter from his PC in order to slot in a USB stick and copy some files. When I re-connected the adapter, I lost internet access and still can't get it back !
Under available networks, it sees a powerful Wi-Fi signal and Device Manager shows the adapter as working fine too. If I click on "Connect" for our Wi-Fi signal, it tries and then states it can not connect.
I have rebooted the PC many times, rebooted the cable modem, even completed a system restore for a couple of days back and still I can't connect.
Anybody have any ideas as this is baffling given all I did was remove the USB connector and then put it back in again (have tried various USB sockets too).
