The strange thing is that when I go to my sister's home the wifi works fine. I call both Dell and Verizon and they both blame each other.
I purchased a D-Link DWA-643 Xtreme N ExpressCard Notebook adapter. The laptop picks up the wifi with this card when I am on the first floor and I am able to connect to the internet. When I try connecting when I am on the second floor of my home both network connections read "Wireless Network Connection Wireless connection unavailable." I am have to access the internet on the second floor as it is there that I work. Any assistance will be greatly appreciated. Thanks.
