5G and now HP wifi printer has trouble connecting

[#1]

We just got 5G and everything seems to work fine.  However, the HP LaserJet isn't connecting  . . .

Can print sometimes from some devices on the wifi, but other times it times out.  It is VERY slow, like 10 - 15 minutes later.

I'm able to reach the printer on a browser via IP address only sometimes, other times it times out.

Is there a setting somewhere that is keeping this from staying connected?

Thanks!

For the helpers to help you better, it would help to know the brand and model of your Wi-Fi router.

Sure.  It is the big, white one that came with the Verizon 5G.  This information is on the bottom:

Wistron NeWeb Corp.

Model: Router LRV5-100

It is my understanding that with this 5G, there is no wired connection in our home any longer, it's all WiFi.

That question might be better answered at the Verizon Wireless forum.

This forum is for FiOS. We unfortunately have no experience using the 5G router.
