The reason I asked is because I was about to re-remind you that the stuff is in the router's manual and you should go look that up. But then I decided I could probably look it up myself and then tell you exactly how to do it, what the default password is, and everything. But I can't do that without a precise model number. So never mind.

In any case... If you rewind to the very very beginning of this thread, the first paragraph of my first reply, where I said "set your player to DHCP and it should Just Work"... try that first. If it works, then you don't need to do anything with the router, so don't worry about it unless that doesn't work.
