NETGEAR cable modem

Brand: NETGEAR (clearly visible on the side).

Connection: On the bottom right, you can see a coaxial cable connector (the threaded metal pin), which confirms this is for cable internet (e.g., Xfinity, Spectrum, Cox).

Design: It is designed to stand vertically to help with heat dissipation, as cable modems can get quite warm during high-speed data transfers.
