Can’t print with new gateway

I have a Canon Imageclass laser printer. Before we upgraded in December, we could print from all our devices. Now that we have the new modem, it’s been nothing but a 🤬. 

I went to print and can’t. I went into my printer and connected it to the new network. When I go to print, it says it’s offline. I look in my xfinity app and it shows the printer under the connected devices. 

I’m using Apple devices - MacBook, iPad, Mac mini, etc. Worked fine before the new gateway. 

It’s the newest gateway, so there’s no ability to split out the 5ghz and 2.4 ghz.
