[xubuntu-users] Could not find internet address

Sun Nov 2 16:16:46 UTC 2008

Hello Charlie,

I followed your recommendations.

After choosing the method 'Manual' I entered the following:

In the box 'Addresses' I filled in 192.168.2.100 and 192.168.2.1

At 'DNS Servers' I filled in 192.168.2.1

At 'Search Domains' I didn't know what to enter

At DHCP Client ID I couldn't enter anything (the line is grey)

I didn't touch the button 'Routes'.

Still the button <OK> cannot be chosen (is grey).

I installed Xubuntu 8.10 only 2 days before. Schould I consider a
re-install to correct the situation?.

Thanks for your reply, Daan
