I have 3 PCs, a couple of old laptops, a printer & a wireless adsl router (11g)
The wireless adsl router also has 4 ethernet ports (100mb) so my pc plugs into this, an other cable (Cat5 jobbie) goes through a hole in the wall into my daughters bedroom (don't tell Mrs Toad I've drilled through the wall) and my son's pc uses the wireless connection from upstairs. Printer is attached to my pc, and is accessable as long as my pc is switched on, ie. you don't have to log in. Some folders have been set up to share with other users, so we can share files, photos, etc.
The laptops use plug in USB Wireless sticks (about £11 iirc) for when we need to use those
Hey presto, a small network at virtually no cost
