I've tried switching between firmwares 410.2160, 478.104 and 508.1092,
without any difference.

I've moved away from AP, the RX speed went down to 11.6 Mb/s (tested
for 5 minutes), but not visible problems (received 414 MB).

I guess Szymon can have affected BCM4318, will I don't. From
https://forum.openwrt.org/viewtopic.php?id=24208 :
> b43 in Backfire works on most BCM4306-BCM4318-based cards, included master (AP) mode. Unfortunately there are some models of BCM4318 which suffer from transmission problems and are unstable as a result, mostly noticeably when running as AP. Others models of BCM4318 seems to run fine.
