If anything worse - on all three computers.

I have only run memtest on one of the computers - but the other two work fine
on everything else.

That fails - but on my computer everything except Firefox and the command line
can connect OK some of the time.

I have tried 4 network cards in 3 computers. And 2 routers. The only thing
that I have been advised to do - other than those siggested by the LUG is my
ISP's suggestion of firewall problems, which advice I have tried to follow,
but see above. And anyway, at that rate why do Live CDs not work?
