|Thanks "sdfox 7" - I'll note that for the future. |
Right now my TP-LINK does very well, but only because I moved the antenna to a better place on a long cable. When I first installed it the antenna stuck out at the back of the tower, which meant the tower itself was right in the signal path to the router. That might have had some bearing on its poor initial performance. I'd half anticipated it and made sure the card had facility for an antenna cable extension.
Always pop back and let us know the outcome - thanks
