Hi Xianghua,
cool, great that it works now :). Let us know about any findings and interesting results you get out if it. I'd be especially interested if you could confirm the results of the WBMv3 in Italy and maybe could pinpoint the more stable graph of channel alternating to less interference / packet loss for instance. (http://www.open-mesh.org/wiki/2010-06-13-wbm2010-bracciano).
And of course, we love to get any open feedback (both positive or negative), that's the big advantage of Open Source development :).
Cheers, Linus
