My neighbour sent me specs and they said adaptors turn off in standby mode. So now got them back to try again to see if they 'reboot' so to speak when turn on PC again. Hopefully will work as I'm assuming adaptors are better than running an extension cable from main socket in order to have router next to PC which doesn't have wi fi?
I now have the Simpler 200 and all seems well, I think! When connected to the router the green on light stays on and the Ethernet light flashes. Is that how it should be? The other adaptors connected to PC has no lights unless turn PC on.
