Alright, I forget the model name (Not mine heh), but the problem is the wireless device isnt seeing all of the wired computers, and the wired arent seeing the wireless. I believe they are on the same subnet, so that isnt the issue. I had this problem once before, but cant remember how I solved it.
Check they're all on the same workgroup. Easiest solution if this doesn't help (assuming all are seeing the Internet at least), is to install the IPX/NetBIOS protocol on them all, then reboot.
