Turbo mode disappeared

I have MT in Nstreme-Dual mode. I want to upgrade my software from 2.9.51, to new version. I’ve tried MT 3.30, then 4.6, and even 5 beta1, and all the time I can’t see Turbo mode in my configuration. Previously on 2.9.51 Turbo worked fine. Now in “/int wir in pr” I see:
supported-bands=2ghz-b,5ghz,2ghz-g,5ghz-10mhz,5ghz-5mhz,2ghz-10mhz,2ghz-5mhz
I’ve tried to change county code, but nothings happend, Turbo is still not availible in options.
My card is:
interface-type=Atheros AR5213
chip-info=“mac:0x5/0x9, phy:0x43, a5:0x36, a2:0x0, eeprom:0x4006”

How cat I repair it now? Can I downgrade from 5 beta to 2.9.51 (I’ve upgraded my license to new version), without problems?

It should work with turbo too..

can you try to save the config and netinstall it?

I will try netinstall, but I think problem is in wireless driver.

what’s your minipci card?

My card is Atheros 5213 - sparklan compatible
MAC: 00:0E:9B:93:B9:A4

00:0E:9B Ambit Microsystems (DOCSIS cable modem), LAN-Express AS IEEE 802.11g

Strange thing is that in other machine with 2.9.51, the same card is showing Turbo mode in options.

Try to netinstall it and if it doesn’t work, send supoutput file to mikrotik support. We can’t fix the drivers.. : P! but it’s strange that this works in 2.9 and not now.

I’ve send supout to mikrotik support, and no response till now…
I try netinstall - we’ll see if it helps.

good luck!
