When the ISP provides a device that is multifunction all but the modem portion must be deactivated or turned off. It sounds like the modem is a multifunction device with router and WAP capabilities in addition to being a modem. The router functions and wireless functions need to be deactivated so that the device will only function as a modem.

You may wish to enquire if you can get a "modem only" type device.

I just ran into this very thing in 2 of my buildings. The existing equipment worked OK with the old firewall but refused to connect with the new 881W period. What I/we finally figured out, the old existing modem (service provider) required a username and password to logon to the ISP. The old firewall device knew what it was and could run a logon script. After all these years.... no one had a clue. If any you have ever tried to figure out who actually provides the internet and phone service in some of our buildings you will understand this can be almost a brick wall.
Huge problem #2 the old modem had a wap built in and was allowing open connections before the firewall. At one point, I recieved a call from that buildings Bishop that a fellow was picked up standing behind our building with a laptop... I'll quit there! Best I could do was remove the antenna to limit the coverage area.
What actually solved the problem... my FM group, upon being notified of the fellow in the alley thing.... switched service providers and went to broadband with NO Wifi built in at the head end.
I honestly think the GS people might be able to get the job done actually know the existing login info and you get lucky enough to get the right person on the other end when you call. This one is not going to be on any flow-chart.
