Devices only connect to guest network when connecting to super wifi booster

[Toweliechaos]

I've had this issue for a while now and have no idea what the cause is.

I have a number of devices that when they are connecting to one of the super wifi boosters rather than the router will only connect to the guest network, not the main. If I take one of the devices to the router and connect to that, I can connect to the main network but if I disconnect and then re-connect to one of the boosters upstairs, it's the guest network only.

It seems to happen most notably to laptops. Mobile devices don't seem to have the same issue. On my W10 laptops when trying to connect to the main network after putting in the wifi credentials, it spins and then says 'Unable to connect to this network'. 

It makes zero sense to me. Why would connecting to one of the boosters affect the ability to connect to the main network?

@ToweliechaosAre you securing the WiFi with WPA3? If so, and if you're happy to try it, down-grade the setting to WPA2 because there have been issues with variations in the implementation of WPA3 by some vendors.

This is a hunch, something else may end-up being discovered as the root cause.

That's not even an option I can see. My choices are WPA/WPA2 or WPA2.

I have WPA2 selected.

@ToweliechaosOh, strike one suggestion, sorry.

So, I don't have your kit at home so I cannot try some things and report back. I'm afraid that we'll have to just see if someone else can suggest something. If you haven't already done so, you could search this forum for "super wifi" as there have been some issues with it since its roll-out.

Appreciated. I'm curious to see if anyone else has had this problem really.

The list of issues with super wifi would leave me with a long, long list of posts to wade through!
