Wifi with wireless speaker

[Loobs72]

So how do you know which frequency the speaker is connected to?  I'm not very techy sorry

@Loobs72 You will need the Home app on your iPhone or iPad. 
once you have it, add your speaker if it isn't already there, then click on the settings cog

Scroll right down to the bottom and it will tell you which wi-Fi name you are connected to

@Graemew81  Is it in Home Settings as I cannot see in there which wifi it is connected to?    Which frequency are you using yours on?

[Graemew81]

@Loobs72  Open the Home app and in there you should see your HomePod.  Press and hold and it should open up, scroll right to the bottom or press the button that looks like a cog wheel. 
Scroll down to the bottom again and you will see the Wi-Fi name. 
I have my MiniPods on 2.4G and HomePods on 5G. 
it shouldn't really matter which, as long as you choose one. See my earlier guide for that. 
hope this helps
