Firmware V2.2.1.212 requested by Release Notes but not avalable

Update: Its working after firmware upgrade to 2.3.5.26 and with wired backhaul.  It didn't go as planned and orbi upgraded on its own, and I have a new question.

Last evening i tried to upgrade a satalite with 2.3.5.26 but that failed with a message that the file was incorrect.  I craeted a post to the forum with that detail but it seems like i failed to post it correctly as I dont see it

Today when i went back to this and try again i see that the firmware had automatically been upgraded to the current for the router and sats.  Note that the router was not connected to the internet during this time when it self upgraded. The back haul status was listed as poor for both sats.  (distances of my set up are listed below). 

I then placed a tp-link unmanaged swtitch out of the router and connected the wired backhauls to each sat from the switch.  Sat 1 backhaul status is now Good and the other is Config Sync.  I attempted to address that status by deressing the sync buttom on each sat however that status of one sat remains Config Sync.  Don't kow if that is a issue.  HMMM, just checking backhaul status and both sats are now "good".  I have attached wired ethernet to PC from both satalittes and those connections work also.  Next step ther is to attach unmanaged switches to each satalitte

The router is in a basement.  One satalite is about 35 feet away on the first floor.  without the wired backhaul the satalitte wireless connection to this sat  varied between fair and good.  The other satalite is in an detached office approx 120  feet from the router and approx 105 feet from sat 1 to sat 2.  home construction is log home with metal roof.  I live in a very rural area and clsoest neighbor residence is about 1000 feet away and live adjacent to 250,000 acres of unihabited federal land.  the wireless siganl outside the home is very good in terms of distance and have not reached it's limits yet, but end to end exceeds 200 feet in one of the dimensions.

I have not chanegd and settings of teh Orbi system, but if there is something I should do be happy to know.  I have until Sept 30 to evaluate it before the return window to Amazon closes for this item  I will be evaluating it closely.

I Have now switched over to sole use of the Orbi vs the Dlink I previously

Thanks again all for folks advice.
