Roku Express+ Suddenly Not Detecting Router

I've had the same setup in my house for at least a year.  Yesterday, my roku suddenly showed no internet connection.  Tried to setup internet again, but it doesn't display my router.  I have restarted router, modem, and roku multiple times.  Reset connection, factory reset router, and finally factory reset roku and still nothing.  Every other device I have is still functioning normally and displaying the correct router information.  Again, nothing has changed within my home setup for at least a year.  I have spectrum internet, SN is S012304LD6HA.

    Does it display other Wi-Fi networks?  It's quite possible that your router received an update that caused it to turn off the 2.4GHz Wi-Fi by default.  (Model numbers are better but I believe every Roku product labeled "Express+" was 2.4GHz only.)

      Model number is 3931X.  Yes, it does display other networks.  Before I reset my device, it said last check for updates was 8/23/23, last actual update was some time in May, can't remember exact date.

        Yes, the 3931 is a 2.4GHz b/g/n-only device. 

        Does "device" refer to router?  Or Roku?

        Does the router say it is broadcasting 2.4GHz?  Also, it’s good to make sure all modes are allowed: b/g/n.  Rokus don’t seem to play well with some routers if only g/n modes are allowed.  Some people have had luck with a simple reboot of the router, but if you’re already in there, you might as well check if 2.4GHz is enabled before the reboot.
