5.4Ghz to 5.6Ghz bands not available anymore on Turbo

Hi,

We have (2) bridges set up using 5Ghz Turbo in the 5.4Ghz and the country set to “Brazil”. HOWEVER, on the new RB433’s we just received, when I program them the same, when I set the country to Brazil, it says

“Couldn’t change interface - bad band and/or channel, see ‘wireless info’ for supported channels (6)”

I have the SAME equipment, XR2 cards, everything. nothing gives, any thoughts?
