This is the Netgear 6100D, providing connectivity via Sprint’s network. Even though the software of this device is terrible, it’s pretty good hardware-wise. It even has PoE! (But only on the WAN port for some bizarre reason. That’s why it has 2 ethernet cables running to it; One is just for power.) There’s also a coax cable attached to it, connecting to a directional antenna in my attic! I did a whole video about that install.
