R6700v3 Firmware update V1.0.4.122_10.0.95 problem

Update: After doing a factory reset on my router, I was able to successfully access the Admin page via PC. Then, after restoring settings via backup from the previous firmware version, I once again lost access to the Admin page on the PC. However, I was able to access the more limited Admin pages via the iOS app (missing such key items as SSID config's, backup/restore settings options, etc.). Internet connectivity was actually fine via PC (wired Ethernet connection) as well as via WiFi devices (able to confirm all devices connected within the iOS app's Admin panel). Even though I was able to access Internet from that point on from all devices, being completely unable to access the full router Admin site from the PC was not going to be acceptable long-term.

I wound up doing another factory reset to the router (which, again, preserved the firmware update itself to ver 1.0.4.122_10.0.95) and then manually restoring all of my settings as best as I could recall from memory (*not* from a previous backup file), making sure to turn OFF the auto-update firmware setting (default setting was to ON) and resolving to never again initiate a router firmware update via the iOS app's Admin panel, as others have also suggested. Since doing this, everything appears to have been working normally in terms of Internet connectivity and access to full Admin page via wired PC, as well as the more-limited Admin panel on iOS app via WiFi.

Although those steps resolved my problem, it is still disappointing that Netgear did not proactively note this was a possibility before proceeding with the upgrade. Also, that it is, apparently, not possible for me to view my earlier backup file's settings in order to confirm that I've correctly set all of my router's settings manually to match the way that I had it configured before. 

I would suggest that Netgear disable the ability to update firmware via WiFi app (restricting firmware updates to be initiated from a wired PC only) or, at the least, include a warning that starting an update via WiFi app can lead to inability to access router's Admin page from PC going forward. Also, please set the default setting for auto firmware updates to OFF so that a user must opt-in for auto-updates or manually start update process when convenient for user to do so...

Thanks to all for your suggestions & attempts to help!
