re: Linksys Velop router suddenly tells me my password was incorrect

I have a Linksys Velop set up installed not quite four years ago.

We have connectivity issues all the time. The app is complete crap. Routinely have to unplug and replug nodes to re-establish connection.

Really want to swap out to a different system but too much invested in this one. Need to let it crap out for good then upgrade.
