My HomePod Minis won’t connect to new wifi network

Hello. I have 3 HomePod Minis that were connected to my wifi network. After some technical issues I had go get a new cable modem and set up a new wifi network with a different name (the previous cable modem had to have 2 separate wifi networks). Now the minis won’t connect no matter what I go. I tried: powercycling them, powercyclng and then holding down the top of the mini to get 3 beeps (I didn’t get any), tried holding my iPhone with the home app on it next to my he mini to see if it would identify and connect, but it didn’t, looked for a QR code on the original box,, but there’s nothing. And they no longer show up on the Home app. So what do I do? I depend on the minis a lot.
