I took the plunge and acquired two Linksys WRT54GL routers to convert over to HSMM. I followed the instructions from hsmm-mesh.org and the flash update was quick and easy. Was really amazed at how easy it was to convert them. Once they were updated and I put in my call sign they automatically connected to each other. I played with them for a few hours until I was comfortable with the firmware and setting. Then I took one next door to my in-laws house and found that the connection was pretty good with just the factory rubber ducks. After that, the ham in me took over and it was time to experiment!
