    Samsung Galaxy S7 on Verizon, Android 7.0

    Western Digital N750 Dual band router, with 4 networks set up (regular and guest nets on both 2.4 and 5.6). My normal wifi connection is to the regular 2.4 net.

    A week or so ago I was connected to my normal home 2.4 net when I had a popup saying something about some abnormal wifi activity being detected and asked if I wanted to block this, or words to that effect (wish I had kept notes on exactly what it said). I clicked the button to block it.

    Since then I have not been able to connect to that same home net. It goes through the motions, says I'm connected then immediately disconnects and reconnects to one of the other 3 home nets. None of my other devices have any trouble connecting to this net, so it seems to be a problem with the phone only. I cannot find anything about how to remove this block that I apparently added.

    I have told it to "forget" the problem net, but it still cannot hold the connection after I reconnect and add in the password.

    Elsewhere I've seen recommendations to turn off Smart Switch, but that hasn't helped.

    And of course, I've rebooted the phone a number of times.

    Any suggestions?

    In case this helps somebody else ...

    I fixed this by going into the router and changing the SSID for the problem net. This then necessitated reconfiguring all my wifi devices to connect to this "new" net.

    Later I found what I think is the culprit in a Verizon app called "Security & Privacy". Under "Wi-Fi security" it listed 2 blocked networks, one of which was the home net in question's original SSID. The description in the app for blocked networks is "Networks you always disconnect from", which sounds exactly like what I was seeing. I removed the entry for the original SSID, but now that I've changed the net's SSID, I can't easily go back and try connecting to the original SSID to see if that would have fixed it (but I'm 99.9% sure it would).
