HP ENVY 5300 Will Not Connect to New White Gateway

Hello, I just got a new Xfinity Gateway on Tuesday and since then, I cannot get my printer to connect to my WiFi. It is on the 2.4 Ghz band and have reset it and restarted it. All my other items in my home have re-connected with no issue. Can you please assist? It looks like this is a known issue from others posting in the forum so wondering if there is a fix out there or if I have to get a differently-branded printer for it to work wirelessly.
