Odd iPhone 16 behavior after Orbi 772 FW update
I received a new Orbi 772 system (with FW 10.5.18.3) about 3 weeks ago and the system appeared to be trouble-free until a few days ago, when I finally took the latest FW update (10.5.19.5). While mo...

Hello @ donawalt and thank you for the very detailed reply! I wonder if you have an IT background...
Since there were no issues with this iPhone 16 before the latest Orbi FW update, and as you seem to suggest, I will try first reverting to the Orbi FW version before the latest, i.e. back to 10.5.18.3
However, after downloading the FW from the NG website, I ran into an issue. After unzipping the download, I noticed the FW file has an extension .chk, but the Orbi User Manual clearly states that "The firmware file name ends in .img" . I don't want to proceed, until I clarify this discrepancy, as I am afraid I could "brick" the Orbi system.
Do you know anything about this?

Yes Orbi only uses .chk files. The User manuals may need to be updated as .img was from 10+ years ago with older NG routers.
I use this all the time when manually updating Orbi systems:

@ FURRYe38 thanks for the procedure document. It was very useful, especially given that the User Manual is a bit out of date on the subject of FW updates.
I was able to re-install the old FW 10.5.18.3 in both satellite and router, and now I will do more testing with the iPhone 16.

Can disable Auto update to prevent any FW from happening automatically.

I already did at the very beginning. I like to be in control of what FW version I am using
