There were attempts to use them with 'alternative' EEPROM data supplied on the flash chip which seems to be 'intended' for running an unpatched driver. However, while this at least seems to work for the lower half of the channels, I had one device blown by using it on > 5.5GHz channels. Also sensitivity is apparently not as nice as with ubnt hance don't expect the same range as we enjoyed with ath9k-based ubnt hardware. @lynxis was involved back then and we still haven't finally concluded if the problem was a failure of that specific device or if it was caused by wrong power-offsets in that alternative EEPROM data. See also https://github.com/freifunk-gluon/gluon/issues/796 we backports those now-reverted patches from OpenWrt into gluon, as they are only using it on channel 36-44 and that has worked well for everyone till now. It'd be interesting to retry this now that we have DFS support in mesh mode (risking to burn the device(s)) :) I'd recommend using outdoor cases with built-in MiMo antennas and sticking eg. MikroTik boards into them with MediaTek MT7612E based mPCIe WiFi modules. That's not that ready-made and also a bit more expensive though -- however, the MikroTik board got 'real' 802.3 PoE and there ain't anything nicer than MT7612E until recently. Now that MediaTek themselves (!) is supplying support for MT7615E to the OpenWrt-grown mt76 driver this is also a very promissing hardware especially for mesh topologies as it supports MU-MiMo. So for the time after: https://patchwork.kernel.org/project/linux-wireless/list/?series=97033 This would be a good combination: https://www.mikrotik-store.eu/en/mikrotik-rbm33g https://www.aliexpress.com/store/product/4x4-802-11ac-Wave2-1733Mbps-MiniPC… (you have to modify mPCIe socket to supply 5V power!) Outdoor case around it and 4 differently polarized antennas... Cheers Daniel
