Ok, so its taken me 2 days but I've finally managed to get onto Wifi.
For a while I was playing error code bingo! It's like treasure hunt getting to the route of the problem.
What I will say is that my Wii doesnt seem to like my particular router, an Actiontec.
Anyway, long story short...anyone have a prob with Actiontec Wireless Router gimme a shout.
