Netgear Nighthawk CAX30 recent issue

We bought a Netgear Nighthawk CAX30 device within the last year, as our previous Netgear was a 3-4 years old. Since setting up the new device everything was fine until a few days ago. Normally we unplug/replug it if our internet seems laggy for no reason and never an issue.

Couple nights ago our tv (streaming) was pixely so I figured we'd do an unplug/replug and all would be fine. Except it took 3 cycles of that before wifi came back on all devices for some reason. Additionally I noticed our wifi name and password had changed, I looked on the device & figured out it had reset to the original name & password although we didn't do a reset to factory settings. I changed these back to what we had previously set, but there's been an orange 3 blinking on the front of the device now that I don't think was blinking previously.

Is this common for this device? I work from home 2 days a week and we need a reliable connection. Now I'm wondering if we bought the wrong device or if this was just a fluke.
