OK, I've done a search and looked at some previous threads but I want to check before I proceed.
I need to connect a second computer to myexisting Blueyonder cable modem so that my son can access the internet for his homework without hogging my PC

From my research, I reckon I will purchase a LinkSys EtherFast Cable/DSL Router with 4 port switch (what a mouthful) for about £41, a length of cable and a network card for the boy's computer. Anyone envisage any problems - apart from the fact that whenever I try and do anything technical like this, it always goes wrong
Thanks in advance.
