disable MAC address filtering

If you are having trouble connecting the printer to the THMI gateway, you will probably need to create a second network (SSID) which is dedicated to the 2.4 GHz band.  I'll post instructions in the next post.

INSTRUCCIONES

Some devices, such as printers, have trouble connecting to the gateway’s default configuration.

You can have several Wi-Fi networks on the gateway.  You want to leave the default network alone (2.4 & 5 GHz; WPA2/WPA3 and AES security) and add a second, dedicated 2.4 GHz network.  This second network is for devices that can’t connect to the default 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.   (The encryption will automatically change to “TKIP & AES”)  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. You can hide it after you get your devices connected to it.

Here are the T-Mobile support instructions for how to add the second network with the app.

I was able to successfully set up a second network. Thank you for the explanation. Unfortunately it did not solve the problem with my Epson printer. I will try to get help from them.

Thank you again.

I also tried this but no luck. My printer is brand new i cant believe im having this issue 

Maybe WPA2/WPA3 instead of WPA/WPA2. A new printer should work with this.

Perhaps there is an Epson forum somewhere.
