Check the female-to-female "RJ45" 8-pin modular coupler. It may not be
a true CAT5 "straight through" coupler that's used for CAT5 network
cables (Pin 1 on one side appears as Pin 1 on the other side), but a
phone company style "rolled pins" (Pin 1 on one side becomes Pin 8 on
the other) type of coupler.
Non-network/non-technical persons would switch the names around --
because if you put a VOM trace on one side of a flat piece of 8-wire
satin wire to the other side, you would call that "straight through".
But, if you put a pair of 8-pin module connectors properly on it, and
you study it, you'ld see that Pin 1on one side becomes Pin 8 on the
other -- where the wire pairs are "rolled".
Try swapping the beige plastic coupler between radios and see if the
problem follows the coupler. If it does, go to Radio Shack or Home
Depot and LOOK CAREFULLY at the couplers in the blister packs. Study it
for straight-through versus rolled.
Thanks for the suggestions, removed the Couplers altogether.
Eyeballed the RJ-45 this morning and noticed some of the plastic between the pins was slightly bent, straightened it up and then the ethernet port is being recognised. Radio was receiving from Ethernet Port and sending data over RF. However data directed at it's IP address wasn't making it out the ethernet port (looking at it using tcpdump).
Re-crimped the RJ-45 and still the same issue. So to discount the cable/RJ-45 being faulty. I think I'm going to swap that little pigtail with one from another radio (that I know works), as I have access to more than two radios.
