I don't have a phone modem card on my computers.
Tixy, you are right. I don't use a router. When I use a different
computer I
connect it to my ADSL modem by an ethernet cable.
Since ipv6 doesn't seem to cause the problem I removed the boot option
that disabled it.
When I ran "pon dsl-provider" and ifconfig I got

I live in Hong Kong, so Google isn't blocked here, but I couldn't ping
8.8.8.8. The error message was "connect: Network is unreachable".
Please help a non-techie.
