I used to have a wireless network setup. I moved my computer downstairs and plug it directly into the modem/router now. The computer I put upstairs is a dell 8250. I purchased a d link wireless adapter for my xbox, it now serves the upstairs computer for internet. My network no longer works and I don't know how to fix it while using this adapter. I believe it worked automatically without any set up (the internet). I am pretty sure it is connected to my internet and not a neighbors. Thanks for any help.
