I had the same problem with my Epson WF-7520.  However, I was reading a thread on a Cannon connection problem and they solved their problem by changing the Gateway 5G default WPA setting to WPA/WPA2.  That person's complete explanation is below.  Hope that helps someone else.

For my Pixma MG5420, I had to change the WPA version on the Tmobile gateway app (Network tab, select your wifi network, under WPA version, change to WPA/WPA2 from WPA2/WPA3).  Then on the printer, go to Device Settings ->LAN settings, ->wireless lan setup, ->Other setup options, ->Standard setup,->select access point, → Directly enter the access point name, then manually enter your wifi network and the passcode.

I have an Epson ET-4800 that wouldn't connect to the gateway after 5-6 months. I read in the community about changing the WPA from WPA2/WPA3 which was recommended to the WPA/WPA2 and everything is corrected.

I tried the steps above many, many times and could not get my Epson xp 4100 to connect to the 2.4ghz network. I tried multiple passwords and lengths and still could not get it to connect. I couldn't even get my laptop, desktop computer or phone to connect to that 2.4ghz network. This was days of trying. Then I accidentally knocked the plug for the gateway out of the a/c socket. Then bam! the 2.4ghz network worked and the printer connected. Then I tried the computers and they connected to the 2.4ghz network too. So, with my experience here is that even though the gateway is saying it is saving and rebooting. It is not. After you make your changes, let it reboot and then unplug the power and plug it back in.  

This wasn’t mentioned on this thread but this was for the new G4AR white gateway
