Re: Fwd: Billion 7800N
I started another reply, and it had lots of steps to try to repair
this situation, but then I rethought.
If this is a fresh install, and you have no data to keep on the Debian system,
here is a bulletproof solution:
Reinstall.
When you reinstall, don't do anything fancy with network. Just let
it do the default with DHCP. Plug it into the router LAN jack as you
do the install.
Once Debian is installed, run a web browser and go to the webpage
on your router as documented in the router manual. In the router's
web site (something like 192.168.1.1), set up the Internet connection
to login via PPPoE. If you have already set up the router from
your Mac or Windows system and a web browser, you don't need to do
it again from Linux, it will just work.
If the Debian system can see the router website, but not the Internet after
setting up the router with the ISP info, try one reboot of Debian to give
it a chance to load the networking since the router had its configuration done.
This is the shortest and simplest path to fixing up the botched Linux
networking setup you have.
Remember, the idea is to allow the router to be your path to the Internet. It
will handle everything, and the Linux system only needs to get on the LAN,
behind the firewall on the router.
