Hi! I remember that there is no external PA on Miwifi Mini so this patch may be useless :-( BTW There is no external PA and external LNA support in current rt2x00 driver. 2015-09-01 0:11 GMT+08:00 D.

I've been testing with this change for a few days now, and the signal levels are much better (roughly +15 in SNR). Also, someone on this ticket <https://dev.openwrt.org/ticket/20369#comment:3> has a similar experience. Finally, I've stumbled upon this change in @rssnsj's GitHub as well (this commit <https://github.com/rssnsj/openwrt-xiaomi-mini/commit/121d32edd2293259430aae6d1d58115dc064bb29> ).

Do you mean that our RT5390 is lacking this support? Either way, wouldn't enabling it on the board (if present) improve things regardless? > 2015-09-01 0:11 GMT+08:00 D.
