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?
I do not have an Espon printer, so I can't help with that part. The first part is to create a 2.4 GHz network on your T-Mobile gateway.
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.
