@wrongthink >also detest ISPs that restrict the management of their modems to some web application on their site.
Some ISPs don't even let you manage the modem on your property - all you get is a black box that has a 100BASE-TX port on it.

While you can use your own router, good luck figuring out in a hurry which arbitrary VLAN and static IPv4 address to set (yes, no IPv6 for you peasants).
