Sky Broadband not working with smart devices

[supercm]

I switched to Sky Broadband this week and now my smart plugs/lightbulbs won't connect with the Sky hub. 

I read it's because they only work on 2.4Ghz. I tried to disable 5Ghz only but that cancels the whole security and connection drops completely. How can I disable one but not the other?

I figured it out, I clicked the unsynchronize button! Works now 😁
