I'm not sure if this is the right place to report/ask about this matter so I'll try to make it short and please ask for any additional information that could be important.
We are building a free network in a small town in Córdoba, Argentina. The hardware we are using for the nodes is: TPlink MR-3220 + usb wifi dongle WN722N So each node has two interfaces, internal + USB. The software is OpenWRT (trunk) and batman-adv as dynamic routing protocol. We have been using OpenWRT Rev.29660 for a couple of weeks, but after we updated to Rev.31077 (to test batman-adv 2012.0.0), the WN722N dongles (which use ath9k_htc) are always stuck at 1Mbit/s bitrate. This only happens in ad-hoc mode, infrastructure works fine. We have tested other dongles: WN7200ND, which use rt2800usb and this problem is not present (bitrate is 150Mbit/s as it should be), same thing with the internal (ath9k) interfaces in the MR-3220 routers. We haven't had the opportunity to trace down the problem to a specific revision, but we know it is somewhere between r.29660 and r.31077 Please let us know what information would be relevant in order to help nail this problem and we will report it. On a side note, we would like to ask if there's any wifi/usb chipset that's known to work well in ad-hoc mode. This community network[0] is the first of many we will be building during this year in the area. We are testing the possibilities of cheap multi-interface nodes because we are working with a very low income population.
