Linksys Wireless NIC PCMCIA card

I live in a building that has wireless network.

It was working fine yesterday mornig, but the signal was a very low and was runninng slow, so I right clicked on the wireless connection and click on repair. Now I cant connect to the network, when I click on repair again it goes through reconnecting but then eventually gives a message saying it cant connect, please contact network administrator.

I did notice that the green light is also no longer showing on the linsky card.

I have tried the following:

Scanning for new hardware changes
taken the nic out and back in
restarted laptop several times
checked in device manager and the network card shows with no problems, it says this device is working properly.

Any advice Im stuck to what to try next.

Thanks
