Router configuration problems.....

I just got high speed internet access the other day and I tried to set up a router so I can get access on my laptop from my desktop. I have had the router for a couple years (Truemobile 2300) but this is the first time I've had the opportunity to use it.

Anyway, as I went to install it I kept getting a message at the end of the install saying that it can't be configured. Do you think I might need a new driver for this router since it's a couple years old? I asked my cable company but they were of no help at all. I really don't know what to do now - I'd like to be able to use this one rather than go buy another one.
