Hi everyone,

I have a TP-Link TL-SG105-M2 (5-port 2.5G unmanaged switch) and I've been noticing a weird issue with one specific cable that runs from the switch to my PC.

Here's what's happening:

- Whichever port I plug this cable into, the port LED stays completely off

- Other cables on the same ports light up normally

- Despite the LED being off, the connection negotiates fine, and I get speeds well over 2000 Mbps

I'm planning to re-terminate the RJ45 connectors on both ends, or replace the whole cable run if needed, but curious to hear your thoughts first. Thanks!
