C3700 Wireless Gateway Radio Crashes

I've got a C3700-100NAS hooked up to my Mac via ethernet. This is the second time that the wireless disabled itself (the first time it seemed to randomly turn back on after lots of coaxing, and I don't remember what we did to have that occur). For some reason, when I go into router login.net, and either a) apply the wireless gateway that way or b) just try to access the advanced tab at all, the router restarts itself, and I have to start over again, but never getting past the point of just allowing myself to enable to wireless within the server itself. Of course, the button is useless to me, too, as it responds to nothing.

Is there some method that would allow me to force it to enable the wireless again? Does this make it faulty in some way? Also, should I try to reset it completely? I'm not sure how to find the reset on this device.

Thanks and let me know if this requires more information. I've been trying to get it to work via ethernet on Mac 10.5, but in the last time it had this problem, I also tried via ethernet on Mac 10.8.
