TMO-G4AR gateway, Epson ET-2850 printer wirelss connection failure.
TMO-G4AR gateway, Epson ET-2850 printer. Tried everything but always get MAC Address failure during wireless setup. Everything else in house works fine and connected immediately at initial setup incl...
2.4 GHz + WPA/WPA2 almost always works for printers.
If you can connect your printer via USB to a computer that is connected to your Wi-Fi network, that will work too. (In Windows, turn on Sharing in the printer properties.)
Can you find an Epson forum to find other users with your specific model?

INSTRUCCIONES
You can have several Wi-Fi networks on the gateway. You want to leave the default network alone (2.4 & 5 GHz; WPA2/WPA3 security) and add a second, dedicated 2.4 GHz network.
Add the second network with the + sign at the bottom of the Network tab in the T-Mobile Internet app on your phone. For this new network, set the band to 2.4 GHz and set the WPA version to WPA/WPA2. Try connecting your printer to this second network. Use the default network for your other devices, as much as possible. Note that WPA/WPA2 (on the second network) is less secure, so I recommend setting this network to be Hidden.
Here are the T-Mobile support instructions for how to add the second network with the app.

Main instructions
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.
