To answer your specific question: renumber the client router. if ahcp is working it should automagically pick up the nearest machines and 'route'. If not, tis easiest to set them up as servers routers for now. Depending on the density of your mesh and the relative need for failover you will want to use multiple 5 and 2.4 ghz channels in any given area. > > Very cool. > > 1) I spent some time this morning cleaning up and I hope vastly > improved the document > > http://www.bufferbloat.net/projects/cerowrt/wiki/Mesh > > Let me know if that helps. > > 2) Some changes in openwrt in late october in the startup scripts and > lua broke startup for AHCP. :( > > if the AHCPD process is not running after you configure it, then I > have to come up with a fix, but it can be made to go with a one liner > in /etc/rc.local and generating the 3 line ahcp.conf file > > I'll fix it for rc8 > > 3) I discovered that txqueuelen 40 was less buggy than 37, and of late > I've been working with some QFQ and SFQ based scripts > =A0 that make much longer txqueuelens feasible, and even desirable. > > 4) Getting the first two nodes to work is hard.
