no internet [solved]

Hello everybody!

I have set up a computer for my girlfriend's parents with windows/gentoo last year. Everything was working so far. When we visit them, i only have time to do emerge sync. Now I have some time to do an update, but I realized there is no connection to the internet from gentoo. From windows everything is ok.
With gentoo i can reach the small router (d-link). But no farther. When gentoo boots, it gets the IP address via dhcp. Tried a static IP address also. No effect.

Is there a configuration file need to change? There is no '._cfg????*' file in /etc

Hello bunder!

I can ping 192.168.0.1. I can even bring in the config page of the router with konqueror. (Using that IP address)
But cannot ping other thing by name, but can by IP address (tryed on yahoo.com)
Think we getting closer... Something wrong with that DNS service?

If you can ping via IP address and not by hostname, to me it sounds definately like a DNS issue.

Whats the DNS setting under windows? Are they different to the Gentoo install ie; Under windows is the primary DNS hosts is using your ISPs DNS server, yet Gentoo is using the router as it's DNS server.

Well...

Under windows the DNS part is set to find DNS service automatically.
In Gentoo, the /etc/conf.d/net is the same as in Gentoo Handbook / System config part.

The ISP settings is stored inside the router (PPPoE)

Sorry, I'm not an expert, so how can I check what DNS service is Gentoo using?

I have foiund in /etc/resolv.conf two nameserver IP address.
I cannot ping them neither from windows or gentoo. Does this do something with this dns issue?

in your resolv.conf you should put your router as your name server.

eg

Yes!!!! It's working!!!!

Thank You all for the help!!!!

As dre2004 suggested I put 192.168.0.1 (the router IP address) in /etc/resolv.conf
And now it's working.

Last question: how did this happend? Maybe the ISP has changed their nameservers, and did not get resolved in gentoo?

Thank you for the help!!!!

Generally ISP's have a whole heap of DNS servers which they dynamically allocate to your modem/router. Its always best to use your modem/router as a name server because it will know which DNS servers to use.
