I am using a laptop and sharing a wireless network with my roommate. Suddently, I cannot use my network anymore while my roommate has no problem at all. It said Limited or No Conectivity. I read a lot abot this problem in the websites and seem like many people have the same problem and couldn't fix it. The network works when I use the cable and connect my laptop directly to the wireless modem. However, I firgured out that the IP of the wireless is wrong (either different with the one of cable of 0.0.0.0). I can also connect to my neighbour's network well. I even went to the Internet Protocol (TCP/IP) Properties, click Use the following address and typed exactly what I saw of the cable (with ipconfig /all in DOS). I was full of hope when the connect sign show up, but too bad, even though every information show up well, I sill cannot connect to the internet. I used WinSock and the Repair function of Windows XP as well, but none work. I reformated and reinstalled, too. The command "ipconfig /renew" is no good, either. I will appreciate any kind of help. Please! D. P/S: Even if you ask me to redo any thing I have done, I will be happy to do that.
