Stumpled upon this when looking for a cheap homeplug set, and finding it to have 4 ethernet ports for £24.99 from play was an awesome bargain!
However, in order it to work you need 2. Which would mean 2 for £49.98, but thats still cheaper compared to some of the other homeplugs out there, heck even on play they've got the Home kit which has two of these for £99.99. So its definitely a saving and you get a couple ethernet cables with them to get you started!
A couple of these are perfect if your hooking your Xbox 360 up wirelessly or just your home network and they are very efficient and very well reviewed. Get your 360 hooking up to Live for cheaper than the official wireless adapter, and its got 4 ports so you can have upto 4 devices hooked up.
Amazon.co.uk: £49.99 (Each)
Dont forget Quidco and 5% off for RAC Members!
