The Raspberry Pi Pico is a very capable board, but it’s still a surprise to see bit-banged 100 MBit/s Fast Ethernet implemented on one. [Steve]’s Pico-100BASE-TX library allows an RP2040 (or RP2350) ...

Ethernet isn't strictly a protocol in itself, as it only defines the Layer 1 (physical) and Layer 2 (data link) of a network topology. The seven-layer Open Systems Interconnection (OSI) network model ...

The technology started with 10-Mb/s coax cabling (10BASE5). Twisted-pair and RJ45 connectors quickly replaced that, while fiber optics was implemented for high-speed, long-distance communication.

The Ethernet port on your TV could be slowing down your streaming experience rather than speeding it up.
