This forum again rocks.... Problem solved!!!!! At first, the reply above appeared as if its another spam, someone just trying to use this opportunity to advertise. But I gave a call at the 24/7 telephone number just to checkout if there is someone to help me out and wow!!!!!!!!!! A prompt help by Mr. Madhu.
Well he very calmly told me the solution which i am writing below for the benefit and knowledge of all. Hope it helps someone else as well.
1. This method is specific to UT Starcom WA3002 G4, provided by BSNL as type II modem.
2. One router(common lingo "Modem") shall be connected to the telephone line with the default settings as done by the BSNL guys anywhere in the house for internet connection. You dont need to do any setting change in that one..... just make sure that wireless is enabled and not disabled.
3. The second router which I wanted to connect to my desktop(Away from the first router) needs to be configured.
4. In the desktop open internet explorer(Or any other application you use for surfing) and type 192.168.1.1 in the address bar(With the 2nd router connected to it).
5. A username and password prompt shall appear. Enter "admin" as the username as well as the password(without the quotes).
6. You shall find a page displaying setting of your router(modem).
7. On the left hand side click the wireless tab. After clicking you will find other options beneath "Wireless" such as Basic,Security,Mac Filter,Wireless Bridge, Advanced and Station Info.
8. Now click Wireless Bridge option under the wireless section.
9. You should see a page with two options:
(a) AP Mode: with two options Access point and Wireless Bridge
(b) Bridge Restrict
isabled, enabled(scan) and enabled
10. Select Wireless bridge in AP mode and Disabled in Bridge Restrict. I dont know very much about Bridge restrict so let me know if someone else is already aware of it.
11. Now save/ apply at the bottom and restart your 2nd router.
12. This is configured now to act as a wireless network adapter for your desktop.
13. Now connect your desktop to the internet via the two routers as I wanted.
Similar options might be available in other routers as well so as to get the same result.
Once again I thank Madhu for his help.
