This is probably a simple solve however, when I split the dual frequency to 2.4ghz and 5 ghz why about an hour later has the router combined the two frequencies into a single ssid and how can I stop it. It causes connection issues to equipment further away from the router which is why I need a single 2.4ghz ssid.
For clarification, you mean that you rename the 2.4 and 5 signals with separate names, and the Hub 3 is reverting to a default set up where they have the same name? And before it reverts, you have checked that your wifi devices can see and connect to the two renamed signals?
One thing you can try is a pinhole reset of the Hub3, then applying your preferred settings again. If that still doesn't work, then you have two options - wait for the forum staff to respond (no point phoning first line tech support, they're useless), or buying your own router or wifi mesh system.
Thanks for the reply, all the devices connect to the respective signals. The issues is the router reverts to a single ssid after about an hour. Your bang on about the Tech no help line, if it is not solved by turn it off and on again they are stumped.
