i can connect the cable modem with USB.In that case then i can just connect the player to the computer without any hub and then I could configure the network to work with the player right?

Yep, that's another option... should be pretty straight forward to do. You'll either need a crossover cable between your PC and empeg or plug both into your hub.

I tried going to Linksys.com, clicking products, then putting that model number in the search and it said not found. Amazon has it tho, and yep, it's just a hub.
