I'm running a wireless network at home using my Cube, Tower, and 1400 PB. My problem is everything works great between the Cube and Tower (ethernet connected to the router) but not between the Cube and 1400 (wireless). I can connect the Cube to the 1400, i.e. the Cube shows up on the 1400 desktop, but not the other way around. I am able to ping the 1400 from the Cube but the 1400 doesn't show up under 'Network'. I can also connect to the internet from the 1400. I also have file sharing turned on.

I'm running 10.4.9 on my Cube and 9.1 on my 1400.
Any suggestions.
