PPPOE WAN Dropping Randomly
-
Hello all,
ISP: BT
Country: Scotland
PFSense: 2.7.0For the past few days an issue has been occuring where my WAN interface will go down completely for around 60-90 seconds, before coming back online on it's own. This happens completely randomly, might not happen for 7 or 8 hours, might happen multiple times in the space of 10 minutes. I have changed nothing, my ISP, package, modemn, router pc, network switches, cables are all the same as they always have been and it has worked for years like this.
PFSense is running on an old PC I have, with an Intel nic to a switch for my lan. The setup is fibre to the house, modemn, ethernet cable from the modemn to the WAN port on the NIC in the router PC, then ethernet cable to switch for my LAN. I've rebuilt my PFSense software setup from scratch, setting up all my interfaces and firewall rules from scratch after resetting PFSense to factory defaults. But still the issue persists, I'm at a complete loss...
I've managed to capture the system logs from start to finish of the issue happening, but I don't understand enough to figure out what end this is happening on. (I've tried to remove IP's and any other sensitive information with REDACTED)
If there are any other tests, or information I can provide to assist, please let me know
Kind Regards,

Nov 10 22:39:03 check_reload_status 408 Linkup starting igb0 Nov 10 22:39:03 kernel igb0: link state changed to DOWNThat's not a PPPoE problem. The NIC is actually losing link. So I'd guess a failing modem, cable or NIC.
As a test try swapping WAN to a different NIC and see if the fault follows it or remains on igb0.

Hi Setephen,
Thank you for the insite,
When I rebuilt my setup software wise, I switched which NIC the WAN is in, so previously WAN and LAN were on the top nic, and WAP and DMZ were on the bottom, now it's reversed. The issue is ongoing so I assume the NIC's are fine.I have ordered a new ethernet cable to run from the modemn to the NIC so I'll see if that's the issue...
If not, it'll have to be the modemn in that caseI'll keep the post updated once the cable arives
Thanks again

Can you check the uptime on the modem? Maybe it's rebooting.

I made a mistake in my original post, I didn't know the difference then but I do now.
I don't have a modem, as we have FTTP, so we have an ONT.
I assume there is no web interface for a OTPI've checked the lights on the modem and it all looks fine, I'll try and check when it starts going dropping to see what status lights it gives off
-
Hmm, maybe not. At least not any user interface. BT can probably see if it reboots. Unfortunately fiber still has reached me here.

Well, we're at 48 hours without an incident after switching the ethernet cable that connects the ONT to the router, so it's pretty safe to say you were correct saying it was hardware
Thank you for your support, honestly I wouldn't have guessed a damaged cable would cause something so intermittent and short
Kind Regards,
Mylo
