Internet dropping randomly

noahbb89

Hello,

So I am having random internet drops, I have a new machine and am downloading my Steam game library, so heavy usage, drops seem to be between every few hours and the shortest one was 15 minutes between reboots. The link shows as up, but is not passing traffic, ping out etc, even in the console check for update is unavailable. My box is NOT hosting DNS, it is set as DNS forwarder pointing to my lab DC. This has not been an ISP Issue in the past (using my Buffalo Wireless Router), but I am on Spectrum cable. The only hardware upstream of the router is the cable modem. As soon as the PFsense box is rebooted, service returns. I have been using this about 2 months, and not had the internet drop for weeks on end (Granted not as heavily). And had been functioning fine since the upgrade a week ago, it seems to be triggered by the increased traffic, however the CPU is using <10% and RAM >20%. Download reported from Steam is maxing at 29.3 Mb/s.

PFsense Plus 22.01
i5-750
8 GB of RAM
Supermicro board with integrated Intel NICs

Any thoughts/experience would be appreciated.

What do you see logged in the gateway and system logs when this happens?

Do you have more than one gateway defined?
If you do and the system default gateway is still set to automatic it may be failing over another gateway as the default route. If that's not valid it can present like this.

Set the WAN gateway as default in Sys > Routing > Gateways if so.

@stephenw10 I'm not seeing anything out of the ordinary in logs (caveat, not a network guy, just my home lab is getting nailed by russia the last few months). I do not currently, 1 WAN/Gateway, and 1 LAN.

Ok. Well to start I would set the default gateway to the WAN anyway.
Then I would edit that gateway and disable 'gateway monitoring action'. There is no need to run the various scripts for failover there when you only have one.

But try get the logs covering an outage. Something should be shown there.

@stephenw10 I can definably try changing gateway. The only other I would have is a possibly a tunnel at some point. I did get a notification this morning:

"PF was wedged/busy and has been reset. @ 2022-02-25 10:00:37:"

The only thing I see in the logs is this nothing explaining the cause:
"Feb 25 09:58:23 rc.gateway_alarm 53463 >>> Gateway alarm: WAN_DHCP (Addr:PUBLIC IP REDACTED* Alarm:1 RTT:248.362ms RTTsd:108.131ms Loss:22%:"

@stephenw10 said in Internet dropping randomly:

gateway monitoring action

Right so when you see gateway alarms it triggers the gateway monitoring action. But when you only have one gateway it;s not really necessary so I would disable the action.

However the alarm will be for a reason. Usually and actual WAN issue but could be something just adding latency in firewall. That looks like a real problem though because it's packet loss.

Hard to say if the 'pf wedged' error is cause or effect.
