Ethernet problems with airFiber. May negotiate at low rates (10/100Mbps) across ports (e.g., DATA, CONFIG) or not transfer data at all. May also have issues with certain switch models but work fine with others (e.g., Cisco 3550).
Possible causes / recommended actions
- Firmware incompatibility.
Upgrade to the latest stable firmware on our downloads page.
- Fixed negotiation set on airFiber or switch.
Enable auto-negotiation on both devices.
- Line interference from EMI sources or AM / FM transmitters.
Isolate the radio from potential EMI sources or use ferrite beads with shielded Ethernet cables (e.g., TOUGHCable) to reduce potential interference.
- Cable run is beyond maximum recommended length.
Shorten the Ethernet cable used on the given port of airFiber.
