@David-TP on my deco x80 (not 5G), with iPhone 15 Pro Max, cant connect on 5Ghz band, always on 2.4 Ghz band. i tried manually on deco app to make specific connection preference, on my iphone 15 promax device, prefer 5ghz band, after that i tried to connect with my phone and phone keep rejecting it or unable to connect, i tried to restart the modem and do the same thing, same result unable to connect. but once i changed back to auto or 2.4ghz band, my phone can connect to deco. any solution david?

  @zcx I have the same problem. PX50. Both phones and iPhone 15 pro and iPhone 15 pro max only work on 2.4 and do not see 5. They connect to a mixed network, but are always in the 2.4 range. All other devices work well.
