I have BSNL's Nokia Siemens Network's C2110 broadband modem through which I get an internet connection for my desktop. Now I purchased a Linksys WRT54G wireless router so that my brother's laptop can also connect to the internet. How do I configure the Linksys router to work with the Siemesns modem to create a home network? I followed the instructions on the CD that came with the router but it did not create any internet access.
