i dont use airtel, but i think they run PPPoE(dont worry abt the jargon, its just a way to get broadband into you home...simplistically speaking), in PPPoE based systems you have a user name and a password thru which you connect to your ISP.
Right now your modem probably has the user name and password saved in it, now tht you plan to connect a
router, you have the option of having the user name and password saved on the router instead of the modem. to do this you'll have login to you modem first and put it in bridge mode(make sure you know your ISP user name and password before you do this, bridge mode-try running the Wizard, it'll take you through the steps).
Once the modem is in the bridge mode, you'll need to connect the router to modem and the computer to router, if the router came with a configuration CD run it, and select PPPoE as the type of connection(I think
Netgear routers ask you some thinglike"Does your ISP require you to login with a user name and a password?" on the configuration wizard).
this should work...if it doesnt try powercycling - turn off the computer - router - modem, wait a minute then turn on the modem first wait for it to get in synch(the modem will have a little green light by the name of
ADSL or DSL or Sync or something of tht sort, wait for this light to blink and then go solid)...then turn out the router wait for abt 30 seconds for the router to boot up and then turn on your computer ... see if it works now.
