Swaped from rb433ah+r52hn to x86+r11e-5hnd and signal got twice worser or aprox.
is there any difference if the wireless card will be used via RB14e or directly via minipcie on mainboard?
Does change anything if you swap it back? Are the wireless settings really the same?
yep settings are the same, fun is that rb433ah+52hn perform way better that newer solution j1900 atom +r11e cards in minipcie slots.. thinking if its the power issue? or not
i have also rb14e in stock, but to waste or no the time it is the question
It may happen that the card is not powered enough by the slot. But shouldn’t be.
swapped to 922uag all fine… seems that r11e ac card has some trick and does not work on stock minipcie 
need to migrate to compex solutions, waste of money and time with no info from mikrotik about it
Tx power of ac is total sum of all chains while for n it is per one chain.
I have the same issue with rb11e (iamp1e) + r11e-5hnd, low tx power.
Will RB14E fix the issue?
