Hello there!

I've got a big problem.

I bought a new connection with this router, and the first time i tried to access it it had the default <blank> username and password it, so i changed it. But now i really don't remember what it could be. I tried to reset the router, but it still didn't clear the password. I tried to contact my ISP, and they said they can't access my router remotely, i had to reset it myself. I've tried to reset it many times (holding down the reset button for 10-100 seconds), but by PASSWORD won't be reset.

How can i reset it? Is there perhaps any other reset trick for it?
