Thought i would just update you on my efforts......
Thanks for advise given, with time a bit short and frankly money a premium at the moment i got myself a Linksys WRT54G2. I followed the instructions to the later i.e follow the several thousand stickers on the unit telling me to run the cd first :P and setup was a dream. Connected my pc to it seamlessly, the xbox 360 connected to it seamlessly and the ps3 connected wirelessly to it flawlessly with a signal strength of 70% and secured by WPA2. I'm very happy with the choice and made all the easier with some knowledge gained from this forum...thanks
