Hey, sorry I got it working for now.
I found that I had to reset the router by holding the button around the back for 15s or so, and then boot it back up into defualt settings, then I had to setup the WPA stuff and it's all working fine now - I found that if the power gets cut off and then gets plugged back in, the internet stops on the machines but still works on the router, anyway thankfully so far just leaving the thing on seems to work - I tried what you said Kir and it didnt seem todo anything, it was worth a try though!
