Airtel Broadband and Wireless WRT54G setup

So for a change, something useful from me which is not Vetti Arattai.
I got my airtel conn on this Monday. The Airtel guys came and did the internal wiring for the same and enabled the connection. The marketing guy had promised me to hookup my wireless router. So the tech tried connecting the router and guess what, he plugged in the 110V adapter into the 220V socket and blew the fuse for the entire house. For a while I was worried that the router was fried. Yesterday, I took the router to some random electronics shop on SP Road and got a 220V adapter for the same. I asked the salesperson to test my router with the adapter before buying it (smart me!!!) and lo and behold!!, it worked (oh joy).

The next hurdle was to hookup the wireless router. Piece of cake...right? Apparently this cake is neither soft not sweet. I first went through the user guide for the wireless router (Linksys WRT54G) and went through setup using the web console. Two major issues arose:

1. Whenever I change the wireless security settings, the web console wouldn't resume.
2. It wouldn't connect to the Internet. (bigger problem than 1 I must admit).

So I started digging around on the Net and found an article that described how to put the Airtel modem in Bridge mode. I tried that, still wouldn't work. I called the Airtel guys and they sent another tech home (not the guy who fried my adapter). After struggling with various settings, he finally managed to get my wireless up. and here's what is needed.

1. Don't mess around with Airtel modem's settings. There's really nothing that you need to change there.
2. hookup the router as per configuration and power it on. Connect it to your computer.
3. Go to http://192.168.1.1 This will open up the Router config (linksys). Choose static IP from the dropdown on the basic setup page.
Enter a static ip such as 192.168.1.100 and set the gateway to 192.168.1.1 (This is your Airtel modem). Do you remember those two DNS IPs that you used for initially setting up your airtel modem? Type those in as well. Change the Local IP to 192.168.0.1 so that it doesn't class with the modem. Change DHCP start IP to 192.168.1.100. Save settings and continue
4. Configure your Wireless settings. Enable security for wireless (128bit WEP is pretty good). Save settings. On my router, whenever I saved settings on the wireless, it wouldn't proceed further but nevertheless the settings would be saved. So i could still safely power cycle to get it back up.

Restart ur modem, ur router and ur pc. And that's it. Everything works. Here's a screen shot of the actual changes that was made to the basic setup.
