I am not able to network in both my brand new windows 7 OS compatible Dell inspiron laptop and with my existing windows 2000 computer. After bought the new laptop, I tried to connect the machine with my existing wireless home network, which is already connected my old machine. I tried to both machines in my home group for playing some of the high definition games from both the machines. Whenever I tried to connect machines, the windows 7 laptop is detected by the other machine but other one is not able to detect windows 7 laptop. What kind of problem is that, I canít understand. I hope someone from here will be able to provide me some information regarding this problem. Any suggestion will be appreciated greatly.
