After much ado and trouble I finally configured my linksys WRT54G v.7 router and connected it to Sify. I feel like god.
I bought this router last saturday from Nehru Place and was unable to configure it. I contacted and called many tech guys but they were unable to help me. I was using a Static IP connection settings and had already configured and cloned the laptop’s MAC on router and WiFi adapter. But whenever i tried to connect, it showed that it could not connect to internet. I was even not able to run the Sify Broadband client.
Now It is finally up and running and i even don’t know how.
Yippeeeeeeeeeee!!!!!!! I am happy!!!!!
