Hello
I use a Teensy 4.1 with the Ethernet kit.
Does anyone know, how to limit the speed to 10Mbps?
I didn't found anything in the NativeEthernet or QNEthernet lib.
Background:
The Ethernet cable is routed through a robot with rotary feedthrough and various connectors and soldering points.
This connection leads to 10Mbps speed when I connect something over this cabeling to my laptop (result from auto-negotiation). Then the connection works without any problems.
When I connect the Teensy Ethernet adapter to my laptop over this connection and set the Windows Ethernet Adapter to fixed 10Mbps, the Teensy can not be pinnged although the cable link LED is on and the connection is correct. So I think, if the Teensy Ethernet adapter speed would be fixed to 10Mbps it should work.
Summary:
1. Ethernet connection over robot wiring from my laptop to another PC with 10Mbps -> ping OK
2. Ethernet connection over robot wiring from my laptop to the Teensy Ethernet adapter -> ping NOK
3. Direct connection from my laptop to the Teensy Ethernet adapter with 100Mbps-> ping OK
4. Direct connection from my laptop to the Teensy Ethernet adapter with fixed 10Mbps in windows adapter-> ping NOK
