I tried the “Enable single SSID” option on my SBG7600AC2 and then realized what it did so I tried to undo it. When I undid it, it forced all devices onto the 2.4GHZ option and even if I connect to the one that is 5.0GHZ on my phone or computer, it says it’s not connected to it through SURFboard Central and also my WiFi sucks now when connected to it. I need it to game and watch streams but now it messed up the quality.
(Please don’t mind the WiFi names, it’s an inside joke )
