Busy network

I have quite the busy network. I run the free basic version of Network Magic on my personal laptop (just 'cause, honestly, it doesn't really do anything for me..). Anyways, here's a breakdown of the devices that it detects on my network (and it's accurate): My Personal Laptop (Windows/Ubuntu Linux) My Work Laptop (Windows) My Desktop (PowerMac G4) 's Laptop (iBook G4) 's Primary Desktop - Games (Windows) 's Secondary Desktop - EQ Trader (Windows) CallVantage VOIP Telephone Adapter (VOIP) Printers sharing Laptop (Ubuntu Linux) Wii (Nintendo) Xbox (Microsoft) That's 10 devices. Ten. Wow. And all except the Xbox are wireless.
