I have a Dell machine that has an internal wireless card and am running Windows Vista on it. The router that I am using in on a computer running windows xp. Every other computers are able to connect to the router via wirelessly without any problems. But in the Vista machine, it will always give me a yellow triangle telling me that I have limited or no connectivity and I am not able to access the internet. I checked that I had to run the power saving mode on high power, so it isnt the issue for me. Can anyone tell me how to solve this problem? Thanks.
