That list hasn't been updated in ages. As a general rule of thumb any ADSL(or ADSL2 that supports ADSL) modem will work with our service. We prefer modems that come pre-configured as transparent bridges but modem that are functioning routers or wireless routers can work as well.
If you have a modem that is not in the list and would like to know if we can make it work, just let me know the make and model and I can tell you. -- Zak
