Ubiquiti SR9 won't on 2.4ghz-g mode

Hi,

I’m setting up a couple of RB133’s each with a a SR9 card and level 4 RouterOS 2.9.38 for tests on a NLOS link.

The problem is that Mikrotik refuses to put the cards in g or b/g mode, so I’m unable to tweak with faster rates and channel spacing.

Am I missing something very basic here or are those cards acting strange?

I’ve searched the forum/net but coudn’t find anyone complaining of a similar problem.

Bellow is the output of the “set band” and “info” commands.

Thanks for any help on the matter.

upgrade to the latest version of routerOS

I did upgrade to 3.0rc4 and yes, that did it.
With the added bonus of now seeing 900mhz frequencies directly without any need for translation.
Thanks
