Lots of Errors in on lan and errors out on AP
-
Here is a screenshot of my statistics
For reference I am using a cisco switch and my AP is connected to the switch and then using a VLAN on the ports coming from the AP and into the pfsense. My modem is connected directly to the wan port on the pfsense box and my lan port is connected to the cisco switch. I've only been using pfsense for a few months but daily I have what seem to be high errors (to me at least). Not sure if its normal or not. I am using adguardhome for my dns which is on a separate server from pfsense. If you need any logs, firewall rules etc etc please let me know. I'm not getting any internet disconnects or devices not getting internet or anything like that. Just curious at to what is causing the errors in and out. Thanks

So two physical NICs in pfSense? What sort?
LAN and WIFI are sharing the same link to switch?
The first thing I'd try is using a different port on the switch. Then a different cable to connect them.
Is the switch showing errors too?

@stephenw10 no. its 1 nic but it has 2 ports. the card is a intel 82576 chip. the lan and wan are connected to that card while the AP is using the built in lan port on the motherboard. the lan and "wifi" port is connected to the switch and then one cable runs from the switch on another port to the AP. those two ports are on a vlan. This was so that the devices connected to the AP got a 10.0.10.x IP while the devices on the actual lan got a 10.0.0.x IP. I have also tried multiple different cables and different ports, all with the same issue of "errors." The switch shows no errors at all. Here is a crude draw.io diagram of a simplified version of what i mean. Its not really a complicated setup at all. The only vlan im running is between the AP to the switch to the pfsense box.

Is everything there using 1G ports?
Seeing some errors on any connection with WiFi is not that unusual. You're not actually seeing any connection issues?
-
@stephenw10 yea everything is running at 1G full duplex and no I'm not seeing any dropouts or anything like that. It's not just the AP port seeing errors though. It's also lan. It's errors in on lan and errors out on AP.

What NIC is the WiFi port?
-
so your 32500 errors amounts to 0.000027 of the almost 1.2 billion packets in and your concerned?
Your out is 0.0002 - I wouldn't be concerned with such numbers.
-
+1 on the counts are so low you probably don't need to worry.
Given that your errors are mainly LAN-In & AP-Out, it sounds like packets going from the LAN to the AP ?
If you really want to analyse them, maybe do a tcpdump or two on PfSense, and then look for error packets only in Wireshark ?
-
@johnpoz not concerned really. More of a hey I've been using this thing for like 2 months and curious as to why it's giving errors in the first place and wanted to learn now how to figure out where the issue could be so that if it does become a problem later I know how to find it
-
@pwood999 thanks. I'll start there. But wouldn't it be from the AP to the LAN?
-
From the firewall/NIC view packets coming into the LAN and leaving the to AP would be like a LAN side client uploading a file to something on WiFi.
If there's interference or just not available bandwidth you may see errors. Traffic over WiFi pretty much always sees some errors. But I would usually expect to see them on the AP interface only.
-
no idea if those happened like 5 minutes before you posted or 2 months ago, or a slow 1 packet ever million or something.
Could be anything - I would only be concerned if they were constantly going up at some rate.. And made up a serious higher percentage than your seeing - could be a blip that happened with application glitch, worried about .00002 seems like a waste of everyone's time
