Changed Wifi password, 5G no longer showing up on Roku stick
Been running wifi via 2 Airport Extremes for many years. On one of them, we connect to our Roku devices. For security reasons, we recently updated our wifi password and had to change that password in a number of places throughout our home wifi network. Roku suddenly began losing the connection and buffering for a long time. I checked the available wireless networks and neither Airport Extreme had 5G available. They have always been there and I can see them on my iPhone but not in the Roku. I did a complete reboot of every device via the Airport Utility and nothing happened. Just for the heck of it, I opened up the 5G network from my Frontier router and that shows up just fine which makes me think that it is the Airport Utility. I have tried re-starting the Airport Utility and rebooting everything there, no change.
One more thing, I have a second Roku stick on a 2nd tv, and 5G shows up there just fine.
Is there anything that I can try to find that 5G network again?
