Guido, myself and a group of people are involved in a project to build community networks in small towns all over the country. It's a project[0] from the National Ministry of Education that involves not only the deployment of a number of nodes in each town in order to get the networks started but also a process of theoretical and practical training mainly targeted at young people in each town. The networks need to meet two important characteristics: 1) easy replication of the network design 2) very low per-node cost We have achieved the second goal with the hardware setup that Guido mentioned but we are having difficulty with the ease of deployment due to the increased complexity of designing mixed ad-hoc/infrastructure networks. We have tested a big number of usb wifi dongles but those based on ath9k_htc have proven to be by far the most stable. On the technical side of this issue, I can add to guido's report that in rev.29960 of Openwrt, with the same configuration, our WN722N dongles were capable of establishing 150Mbit/s HT mode links, although they did not behave as stable as the internal ath9k based radios from the MR3220 routers. With current revs of OpenWRT trunk, the behavior of ath9k-htc dongles in ad-hoc mode has become unusable (always running at 1Mbit/s) so we are forced to mixed mode network designs. We are greatly interested in helping out in any way we can to help solve this issue. We are in charge of three community network deployments that can be used as test beds; these are at your disposal, but please let us know if we can be of assistance in any other way. Cheers!
