4200: System Update (24.11) to (25.07.1) caused WAN port to stop working

@Joe0x7F Have you tried a different ethernet cable for your WAN connection?

@Joe0x7F said in 4200: System Update (24.11) to (25.07.1) caused WAN port to stop working:
I plugged my WAN connection into (“1”)
...
PORT1WAN Interface (wan, igc3)
Status
no carrier'no carrier' mains that port 1 on the 4200 and the WAN could not establish a link on cable level. As @WN1X wrote could it be a cable issue but also that something changed in the driver for the ports that makes speed negotiations fails with the WAN device.
- What is the WAN device you are connecting to?
- If WAN is 1 Gbps you can try set the speed for port 1 of the 4200 manually in the Interface settings, 'Speed and Duplex' to 1 Gbps. If that doesn't help, try also setting the WAN port on the WAN device to 1 Gbps

Thanks for the ideas. That helped a lot to get it to work, but I had to set the Speed low in order to do that. Something must have changed from (24.11) to (25.07.1) affecting this area of the code. Autoselect is apparently not working.

Interfaces
PORT1WAN (igc3)
Speed and Duplex
10baseT/UTP full-duplex <---- !!!!!!
Explicitly set speed and duplex mode for this interface.I was getting these numbers in speed tests (https://www.speedtest.net/) yesterday morning:
Download Mbps = 94.31
Upload Mbps = 11.35Now, I’m getting these numbers:
Download Mbps = 8.94
Upload Mbps = 9.37 -
@Joe0x7F that is only 10 Mbps, way too low for any meaningful work. 1 Gbps didn’t work? Try setting pfSense to Auto and the WAN device interface to 1 Gbps fix.
There has to be a faster speed possible. -
Just a dump idea: if -for what reasons ever- a wire inside the cable is broken ar lost contact this will result in a fast ethernet (100mb / 10Mbps) connection.
So what is about the question about replacing the cable? Did you already checked this out?Regards
-
@FSC830 I already changed cables, and I already changed ports.
-
When you change - re assign - WAN and LAN on pfSense, the rpoblem goes to LAN ?
In that case, you're getting close to a 'broken port' on pfSense.Check the inside of the port, the 8 metal contact strips are ok ?

FWIW the 4200 has this note:
https://docs.netgate.com/pfsense/en/latest/solutions/netgate-4200/io-ports.html#networking-ports"The igc(4) network interfaces on this device do not support fixed speed operation. These interfaces emulate a speed/duplex choice by limiting the values offered during autonegotiation to the speed/duplex value selected in the GUI.
When connecting different devices to these interfaces the peer should typically be set to autonegotiate, not to a specific speed or duplex value. The exception to this is if the peer interface has the same limitation, in which case both peers should select the same negotiation speed."
Not sure if that's helpful at all. Maybe power off the ISP router?

Hi @Gertjan, I just checked them with a flashlight and magnifying glass. All 8 conductors in all 4 ports look the same and perfect.
-
Hi @SteveITS , the problem is I did not change or move any of the cables at all. They were working perfectly. Then, I did a System Update from (24.11) to (25.07.1), and it stopped working. That is all.
I don't see anything here that violates the text you have cited.
But, I think this was a good idea too.
-
Maybe I missed something, but what is connected to the other end of the cable plugged into the WAN port? Is it some kind of modem or what?
This is actually a known issue, and it’s unlikely that the pfSense version is to blame — it’s more likely a link auto-negotiation problem. It just happened to work correctly on 24.11.
Most likely, forcing the link speed on the upstream device connected to that port will help, or simply putting a cheap unmanaged switch between the WAN port and the upstream device. -
I was presuming Joe0x7F already tried several different devices on the other side of the cable.
