well i left it off all night, unplugged everything blah blah. Its not just my laptop, i've tried it on two other wireless devices as well and neither of them can see it either. Its a BT homehub, been working fine for months then just suddenly happened. Done a google, seems to be issues with this and getting a new hub would appear to be like asking for the moon! I'm reasonably ok with technical stuff but would probably find programming the boiler and the dvd recorder a bit easier than this.............
I'll try the suggestion above when i've deciphered it then its the dreaded call to India I guess...
