Abrupt WAN Link down

Firewaller1

Hi team,

Anyone know the possible reason why PfSense WAN Link will abrupt be disconnected ?

Current Fix:

SSH and Manually reboot pfsense

Current Setup:

PfSense hosted on Zimaboard
WAN IP taken via DHCP from ISP

Error Message:
From system.logs

kernel: re0: watchdog timeout
kernel: re0: link state changed to DOWN
check_reload_status[413]: Linkup starting re0
php-fpm[19243]: /rc.linkup: Hotplug event detected for WAN(wan) dynamic IP address (4: dhcp, 6: dhcp6)

After that my internet just went down.

Just a suggestion: take a look if the driver for your NIC is up to date (Realtek I suppose):

pkg search realtek
realtek-re-kmod-198.00_3       Kernel driver for Realtek PCIe Ethernet Controllers

@fireodo Thanks. I've just updated it using re-kmod
realtek-re-kmod-198.00_3 Kernel driver for Realtek PCIe Ethernet Controllers

will test and monitor if the same issue occur again. the configuration doesn't store as backup right ? means i've to manually update it next time if i switch out the hardware installed with pfsense ?

The loader values to load the module that you added to /boot/loader.conf.local will survive an upgrade.

Because it's an installed package it will be upgraded like any other at upgrade too.

It shouldn't require anything.

Just for reference that is the error that indicates you should be using the alternative re driver.
