I was unable to receive a an IP address from my ISP. After some digging I assume that the problem is with the SFP transceiver or the cable or the Omnia itself.
I noticed that tcpdump showed no traffic on the WAN interface, even if I ran udhcpc on it.
cat /sys/class/net/eth2/carrier is always 0 no matter what I plug in.
eth2 is the wan interface according to /etc/config/network.
I have two SFP transceivers and patch cables. All of them I’ve tested with my old router and internet connection.
They are SFP-31W2ASM-10-DR and Siligence, SGA 441SFPO-1Gb, 1.25G T1310nm/R1490nm 10 km DDM.
Is it possible that these are incompatible with the Turris Omnia? I’m starting to reach my wit’s end.
