I have an external wireless card for my PC, D-Link Air Xpert. I'm using an IBM Think Pad computer. There are some wireless networks where the PC starts to boot up, but then the screen turns blue and is filled with error messages. This happened to me in the Omni Hotel in LA last weekend. They gave me a wireless radio to use instead of my wireless card, and it worked.

Is there a different card I should get that will work in all wireless networks? Or something that might work sometimes when my D-Link doesn't work?
