packets lost in WLAN and LAN connection
-
Hi,
we are experiencing a difficult period in Italy right now, where most of the people is forced to work in home office.
Currently I´m experiencing issues with my internet connection resulting in annoying voip lags while chatting over MS Teams with and without screen sharing.
in the last day, I experienced some packets lost from my desktop client, while pinging 8.8.8.8 which i simply explained by a "general internet overload" in Italy.
Today the situation got worse, therefore I performed additional test. I have executed a ping to 8.8.8.8 from my desktop pc and the pfsense box over ssh at the same time, while running a speed test on my desktop´s pc browser.
Following unexpected result
- Desktop to pfsense ping: 100% fine, no packets lost. response time always < 1ms
- Pfsense to 8.8.8.8 (ping executed in ssh shell): 100% fine, no packets lost. response time around 40ms (normal for my radio relay provider). Ping increased to about 55ms while upload speed test was performed.
- Desktop to 8.8.8.8: Fine only by 88%, because I lost 12% of the packets :)
obviously all pings where executed at the same time from the desktop PC
My first Idea was that maybe my TPLink switches are rubbish (TL-SG108 and TL-SG105), so i switched my desktop from LAN to WLAN (TPLink EAP225) . Same result: some packets are lost.
Restart of pfsense box, nothing changed.
Performed another test with my MacBook pro. Packets lost as well.
Result: Pfsense box itself doesn´t lose any packets, but connected clients do.I´m running out of ideas now. I don´t expect pfsense to be so silly to lose packets. There must be an issue in my configuration which I´m unable to recognise at the moment.
Pfsense configuration overview:
WAN over pppoe
Igb0
VLAN 1 on igb0 interface for LAN
VLAN 29 on igbo interface for LAN IOT
Igb1
WLAN on igb1 interface for WLAN
VLAN 20 on igb1 interface for WLAN IOTFirewall rules:
- almost nothing, exempt IOT networks forbidden to talk to "trusted networks"
No traffic shaping.
- Traffic Limiter for WLAN IOT to limit the traffic to 3500 kbit/s down and 500 kbit/s up
Installed packages:
- Avahi
- openvpn client export
- pfBlockerNG (working with floating rules)
Any help is appreciated.
PS: Pfsense is running on an APU.4D4. CPU never goes above 20%
Thank you and best regards from Italy

Hi guys,
I don´t know why but I´ve overlooked following article from the official documentation:
https://docs.netgate.com/pfsense/en/latest/hardware/troubleshooting-lost-traffic-or-disappearing-packets.htmlCurrently it seems, that checking the checkbox is solved my issue.
I´m happy now, but i will continue monitoring the topicBest regards
