Ethernet port problem

MattQ · December 16, 2022, 3:01am

The MiFi device contains an ethernet port, when I plug in ethernet cable,
Realtek USB GbE Family Controller show "unrecognized network"

Ethernet can not get the correct IP
any suggestion?

eth0 Link encap:Ethernet HWaddr 1E:30:5B:64:46:3E
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0

RX bytes:0 (0.0 B) TX bytes:86565 (84.5 KiB)
Interrupt:45

Thanks

The best way to start is to evaluate your configuration:

Please copy the output of the following commands and post it here using the "Preformatted text </> " button:

Remember to redact passwords, MAC addresses and any public IP addresses you may have:

cat /etc/config/network
cat /etc/config/dhcp
cat /etc/config/firewall

What version of OpenWrt are you running? Please provide the output of:

ubus call system board

What are all these extra ports... did you add them? Were they there by default?

MattQ · December 16, 2022, 6:50am

The openwrt version is 21.02:

/ # ubus call system board
{
        "kernel": "5.4.179",
        "hostname": "OpenWrt",
        "system": "ARMv8 Processor rev 0",

        }
}

You should upgrade your device to 22.03 (latest), but at least 21.02.5 to ensure that you are up to date with the security patches and bug fixes.

Meanwhile, what is the device you are using? And did you add all those ports to the lan bridge?
