I setup and configured a Linksys WRT54GS v2.0 Router today to run HSMM-Mesh software version 0.4.3. Unfortunately there are no nodes in my area yet, and only two others registered in RI, but eventually this might become a high speed data backbone for Rhode Island.
At the moment the node is just in my house on the top floor, but eventually it will be mounted to a mast along with a 2.4 GHz dish and a 2.4 GHz omni antenna.
As a FYI, it pulls about 0.80 amps when fed with a 5 VDC source, or 0.23 amps when fed with 13.8 VDC. A 20 AH SLA would run this for more than three days of darkness, and a 25 watt solar panel would keep up with demand assuming 4 hours of full sun a day.
