It's the backup battery that is getting you. Remove that and reboot, if you can. Or unplug it and let the battery run down. Might be a few minutes, might be hours.
Or force a reboot by unconventional means. A change to the router name "Motorola" to "Notorola", save. Should reboot. Then set it back and save again. Doesn't work on all units, but does for many. One Step Zup would do it from the MIB OID panel.
I'm beginning to suspect your landlord is blowing smoke and has no idea what his connection parameters are, and understands your situation even less. Most people deem something unimportant when they don't understand. So, keep an open mind. If you can't appeal to him, try to go around him another way.
