Create a non-root user. Set the group of your network devices to the group of this user (you might even get away with using the group 'root' for this user, makes things easier). Set the network devices to be group-writable. Use the script as this user (might even work to make the script suid to this user, but that could fire up taint checking too).

Or: Just use a group which you give to all your users (i.e. add all your users to the last column of this group in /etc/group). Users have to do 'newgrp <that group>' once in their shell and then can use the network devices if they have the same group. In that case everyone can use their non-root account and the script doesn't need suid since the user has the right to the devices anyway
