Help with wireless card TP-Link tlwn550-g

Hiya,

I bought a tplink nic which initially seems fine, the pc recognises the card and installs the drivers fine, I can see that the nic sees the router but I cant get a connection out of it.

I have various screenshots to display the error, I just get "no link" but when I plug it into a cat5 cable, it connects to the router straight away.

I tired TP Link's support number from the website but it seems to be somewhere in Asia ,I don't get any response, I also emailed them with no joy.

Can anyone help or suggest? also anyone have another number for tp-link support?

I am a tech myself so i have checked all the "obvious" things.
