[xubuntu-users] Could not find internet address

[Daan Hoogland]

Hello Nils,

You are wonderful!!!

I will tell you what went wrong (in connecting manually): entering the
IP-addresses for the pc, netmask and gateway address.
It was not clear to me that I had to click just below the words
'address', 'netmask' and 'gateway' in order to get the appropriate
values entered.
After entering the DNS-address the 'OK'-knob could be pressed and
voila ... contact.

I am very glad you could help me with this. Thanks again!!!.
