It is a WBR-1310 D-Link.
I don't know how to check Ip settings (I have Vista)
Yes it happened all of a sudden
I can remember nothing that happened before this. There was a pop-up after I tried to install the router and when I got to a certain point it said there was a error of no internet going through router. When I had direct line from modem to pc the internet worked fine, but when I connected the modem to the router and the router to the pc I got a reading saying I only had local area connection, and sometimes it said limited or no connectivity. (Yes I have everything attached right I think)
