Installed this unit and it connected and ran quite well. That is until I tried to use a USB port for a memory stick.
Suddenly unable to recognise the stick and my built in card reader no longer works. Remove the adapter and the ports and reader all work fine.
Plug the adapter back in and they all go haywire.
Same thing happens with the TV card. Won't work with the adapter connected, in fact, the adapter has to be removed and the computer rebooted before I can get the TV card to work again.
I bought 2 of these and the same happens with both. Updated drivers don't make any difference.
Keeping the adapter for a spare and going back to using the old D-Link Wireless G adapter. It's only a bit slower but more reliable and less problematic.
