Hi guys.
I have 2 desktop computers at home. One has xp bro 32 bit which is connected to my dir 655 via cable and other one has Vista Ultimate 64 bit which connects via wireless. They used to work like a blast until yesterday.
I dont have any connection at all. I do have my network but no connection. My computer that is connected to the router via cable does not see my router. I can not even open my router`s web page. I did trouble shooting with msn

It said I have a problem with my default gateway. I know connect directly with my cable modem so I know I get the connection and the problem is the router.
I have never heard o***ateway problem before. You can go hardcore on answers and use all sorts of computer terms. Actually I did build one of my computer my self. So I know a little about computers but never heard of a problem like that before.
Thanks !
