assigning networks to ethernet ports

I have a wireless printer that has to connect via a WPS button (no apps available for this printer). I set up a 2.4 gHZ network on my t mobile modem, hooked a Ethernet cable into the back and ran it to a router. Tried connecting the printer wirelessly but it keeps failing

   I think the issue is that the t mobile modem is automatically sending the 5g network out through the Ethernet jacks, instead of the 2.4gHz one I set up. Is there any way to manually assign a network to the Ethernet jacks on the back of the t mobile modem?

Ethernet (wired) is not controlled by the wireless 2.4GHz or 5GHz bands.

Tell us your printer manufacturer and model number, and we may be able to help more.
