Surviving with a static IP
From NAS-Central Buffalo - The Linkstation Wiki
If you are using a static IP, then you might have problems to get a connection from your LS to the free internet. Buffalo never intended that there should be a name resolution on the LS....thats why NTP only works with an IP on an unmodified LS.
The main reason for that is that without dhcp nobody sets the nameservers for you.
you can do that in the file /etc/resolv.conf.
Open the file by
check which nameserver you want to use and add
Here is a vi quick reference if you need help.
You should now be able to ping IPs in the free internet or download with wget directly to your LS!
