Hello, i'm facing a bug after the latest update, my router doesn't show the options to choose between 2.4ghz or 5ghz anymore and all my devices keeps disconnecting and reconnecting on it's own, in some parts of the house I get strong signal but without internet, i'm guessing that i'm connected on 5ghz and i'm not getting internet because i'm far from the router. I don't have any option to switch to 2.4ghz. any help?
