I have an existing laptop connected to the wireless WAA1003A network that exists at my place..... However, there's one problem.. whenever I bring in another laptop.... I can never manage to get that configured to my existing network as well.....

Today, I tried putting some other IP address that I saw floating around in one of the threads (since I didn't know earlier that no 2 systems can have the same IP addresses). Now my 2nd laptop shows the network as connected with Excellent network..... however, I cannot access internet and no websites open in the 2nd system..... Tried the usual that doesnt open either..

what am i doing wrong here ?
Pls help me in setting up the 2nd laptop..

Thanks in advance!
