Hi,
I have a Linksys Wirless Router Model No: WRK54G and a Wireless Card in my laptop Model No: WPC54G. When I connect them, it says on my laptop that the strength is excellent but I can't connect to the internet. However, when I connect my PC and the Laptop, my internet connection goes down on my PC. My router has the channel 6 but I don't know how to change it on my laptop.
Could someone please reply as I need help!!!

Thanks
