WAN interface changed speed from 1000 base to 100 on it's own.

Hello my WAN interface changed speed from 1000 base to 100 base on its own over night dragging down my internet speeds today. Any reason why it did this? I do see it can be set static but it said its advised not to. If I can, which option should I use? Thanks

Have you tried another Cable?

No, It's a pre molded cable and never had an issue on my old setup before I deployed this.. It's just odd it did this. It could be bad but easy enough to check.
Update: Cable seems fine. switched it out anyway. But could there be any way it did it if the cable is good. the cable checks out fine on my RJ45 tester.

Huge interference in the area? Port failing (at either end)? Realtek NICs living up to their reputation? All three....
What are you connecting the WAN port to?

A change from 1 Gb to 100 Mb usually indicates a bad cable. Even pre-molded cables can fail. It's easy enough to try a new one.

I noticed that also on LAN, although it happened once for me on Feb 10, 2020...I am on pfSense 2.5-dev.

Maybe It could be a network crash. I do remember plugging a live port back into the switch on the LAN side accidentally while testing last night. But that was the LAN side not the wan. Maybe it did soemthing.

Why don't you just try another cable? Cables are a very common cause of problems. If there are any broken wires in the cable, the connection may autonegotiate at 100 Mb, but not 1 Gb.
-
There could be a all kinds of reason for this to happen... But yes as mentioned cable could be an issue.. connection could be a problem.. Try resetting the connection - plug the cable in again..

@JKnott I did, see past reply's. I will not know till and if it happens again.
