Radio config: http://pastebin.com/kRw4uTib

high ping!

Stock and D-Link DIR300 nru b5/b6 - ok ping!

HighScreen Boost - cyanogenmod and Mikrotik - ok ping!
Stock and Mikrotik - high ping!

Other devices are working properly. On Androyd tablet - ok (Android 4.4)! Other phones on android - ok...
Only problem with the phone for stock firmware. With other manufacturers of routers operating normally. (DLink, TP-Link, ASUS)
With firmware cyanogenmod problem disappears!

I would like to confirm that the issue happens with Mikrotik devices only.

Tested on:
RB951G
CRS125
mAP 2n

Going to test with:
RB951Ui
RB951-2n

I have attempted to change almost every option with no luck.

Any updates on the status?
This problem is pretty serious. It should be the Mikrotik Wi-fi fault and it need to be debugged!
