How about a switch? Something like this should work: http://www.amazon.co.uk/TP-Link-Unmanaged-Desktop-TL-SF1005D-Plastic/dp/B000FNFSPY/ref=sr_1_1?ie=UTF8&qid=1348422735&sr=8-1 in general the more you pay the more reliable it'll be. You may want a gigabit switch (10/100 is 10MB and 100MB) if you're shifting loads of data, too.
Just a quick warning - chaining cheap switches together is a fast way to have a really slow network, or have odd issues. The odd one or two shouldn't hurt, but in a large network it's best to have a central point to switch from, with decent switches.
