can't upgrade fr8.2.7

ok so i’m upgrading all my 900 aps from 7.2.9 to the latest firmware but i can only get as far as 8.2.7 when i try to upgrade to 8.4.3 using cnut3.0 won’t any thoughts??

8.2.7 is the latest for regular Canopy products.

8.4.3 is for the new Canopy 400 Series stuff.

9.0 is coming, but I would recommend waiting a minimum of 90 days before rolling it out.
