1. try no username and the password as admin / or admin as both user name and password ?
2. also are you using any software like netmagic to access the router ? or are you going through the standard way of 192.168.2.1 or whatever it is for the router
3. are you using cable (ntl/virgin/etc) or adsl ?
4. did you buy this router from a shop / ebay ? or did you get it from an internet provider i.e sky / bt ?
^--- important as some people say that they have hardcoded the default passwords to be your internet accounts details
