That was a bit of a guess about how wicd fills in the netmask field; I had in mind it *computed" it from the IP address. Looking at netentry.py in /usr/usr/share/wicd/gtk it appears its approach is less sophisticated. An IP beginning with 172 get 255.240.0.0. 255.0.0.0 is allocated for IPs eginning with 10. Everything else (including 192.168) gets 255.255.255.0. The gateway IP is formed by adding .1 at the end. So you have the nice situation that an interface IP of 192.168.7.1 (which could be valid) has 192.168.7.1 as a gateway. That will do wonders for getting out on the internet! Wicd would indicate it has successfully connected (which it sort of has) but it would be head scratching time.
