Buying a ADSL modem for Rs. 5250/= and DSL Router for Rs. 500/=

As I got the ADSL package, I got a ADSL modem(D-Link) from Unity Plaza for Rs. 5250/=. Which happens to be the cheapest available. Then few days later, I was there(Unity plaza) again for some other work, then there I leaned that there is a bargaining sale on ground floor on computer gadgets. So I got there and was amazed to find a DSL/Router(Aztech NA3000) available for just Rs. 500/=. I couldn't believe my luck. Correctly there was "No warranty". So I got the equipment with 2 utp cables, power pack with it's cardboard packing. But only problem was missing manual/installation cd. Then I searched the net and found a manual for the exact router. Then I tried to reset the router and give the username and password(admin and epicrouter respectively) to login. But it didn't work!! :(. I posted to here and there and googled and even mailed the technical support of the product. But they were of no use. Anyway 4 ethernet ports are working. (Thank god !). If you are reading this and know how to crack this username/password please be kind enough to let me know.
