why not just run a cat5 from your router to your bedroom?

A what? I am truly clueless when it comes to networking![]()
and having another socket in your bedroom will just reduce your Bb speed. homeplugs or Cat 5.
Oh, It'd be a bit messy though wouldn't it?
the only problem you should have with Homeplugs is if you are different power circuits, this tends to only apply if you have had a conservatory installed or some other house extension installed.
