Seems to me the power supply in the truck is your best bet. The router
probably runs on DC at relatively low power compared to something like a
car stereo, and the truck's battery would make as good an all-weather UPS

consumption of the APs. If the APs are at fault, it's unlikely that we

about:
- 802.11a/g devices are getting scarce, but I've heard rumors that there
were 802.11g devices that required a basic rate of 6, 12, or 24 Mb/s.
It's possible that there are no such devices left, that driver
Be aware, the minimum rate question is far less straight-forward than the
