That is one weird cable! I’m guessing someone took a regular ethernet cable and replaced the connector on one end so it could be used for ADSL.

Ethernet will still run on it, but only at like 10mbps. Which would be enough for your Phillips hub, but please just toss it and replace it with a proper ethernet cable.

I think meshtastic fills a different niche - it’s much longer range and much lower bitrate than Bluetooth
