DUNNIT!!!
turns out that even thou it was 'connected' it wasn't and the reason because I was entering the WEP 26 character key into the 'WEP 40/128-bit ascii box instead of the WEP 40/128-bit HEX box....and when I did hey presto!! it said it was all connected to the internet...so all good thanks for all your help.

Wew! That saves me having to suggest a system reinstall ;) - that little iBook was subject to testing (?abuse?) of all manner of networking stuff and I thought it may have unfortunate legacy lurking around in its system..... Ow yeh you may, if you see a reason for it, want to disable the SMPT server (run postitfix enabler from applications)
