Bizarre! Orbi sort-of loses configuration and won't let me log in

I just ran into a bizarre problem with my Orbi system this morning.

My router/satellite are running v1.4.0.34. My main PC is running Win10x64.

My ISP was doing work in my area, and my internet connection was going in and out for a few hours.

When I reset my cable modem after the ISP work was done, my internet connection was not working. So, I reset power to my Orbi router to clean things up.

And ... this is where things got weird ...

Our internet connection didn't recover, so I decided to go to the Orbi configuration to see what was going on.

I was able to connect once, and the Orbi status screen had a big red bar saying that there wasn't an internet connection.

I decided to reset the cable modem and the Orbi again.

Some of the stuff on my started to connect to the internet after this reset. However, when I tried going to the Orbi configuration page, it kept telling me that my username/password was invalid.

The Orbi eventually went to the password recovery screen where I was prompted with my two personal questions. I answered the questions correctly, and the Orbi brought up a screen that showed the access password ... which was the exact same as the password I was already typing in! After the Orbi brought up the password recovery screen, I was prompted to log in again ... And again, it failed!

I even copied and tried the password that was shown on the recovery screen, and that didn't work, either.

I did a hard reset with the pinhole. When the Orbi powered up, it said that it was changing my IP address to 10.0.0.1 to prevent a conflict with my ISP. (YUK!)

Again, when the Orbi powered up, it said that it didn't have internet connection, though this time I knew my ISP was working properly.

I reset the cable modem and Orbi again, and this time the internet connected, I loaded a previously saved v1.4.0.34 Orbi backup configuration, and the router seemed to be working fine. My devices were connecting with the right IP address, and everything seemed to be connecting to the internet.

Once again, I tried logging into the Orbi configuration page, and I was told again that my username / password was invalid.

What the heck. This is insane.

I did a soft reset this time with the pinhole, and now everything seems to be OK. I have logged into the Orbi a few times now, and I think I'm back to normal.
