I should know the answer to this, but am not sure. We have one SM at a customer house that has been powered down for a year, so obviously it missed the transition to PALs and multigrants, and is still on 16.2.2 FW. Sector uses 20 MHz, so two multigrants.
I am guessing that a truck roll will be required now to upgrade the FW onsite. Or will it still connect to the AP and get a grant so we can upgrade it over the air?
