OPNsense cuts off one client every second hour or so

[guest26348]

Hi dear community,

I have been running OPNsense for a few months now but I have one issue that is driving me nuts. One client, Dell XPS 13 (2018) running Ubuntu 20.04, gets cut off every second hour:ish. It can still access other devices within my lan but not access internet or the firewall. We have like 10-12 devices at home and this is only happening to my XPS 13. So my setup is this:

1Gb/sec fiber via ethernet -> OPNsense, latest version, Intel NICSs -> Switch -> Devices like an Ubuntu Server 20.04, stationary computer with 20.04, AirPort Extreme and some Raspberry Pis. To the AirPort Extreme (only acting as AP) we have 1 MacBook Pro, 2 iPhones, 2 iPads, 2 Apple Watches, Dell XPS 13 and some smart home devices.

So what is happening is that every now and then - I loose internet on my XPS 13 while connected to wifi. First I think wifi issues - but nope, I can still connect to other devices within my LAN, so wifi is fine, but I cannot access the OPNsense FW at all. At the same time my wife is having video meetings on her MacBook Pro (also on the same wifi) without any issues at all.

So to summerize when this is happening, for maybe 1-2 minutes, then I can access internet and OPNsense FW again:

• I cannot access OPNsense (via http or ping) or the internet
• I can access any other device within my LAN via ping, http, etc
• All other devices works flawless during this time and no other devices have any similar issues

What I have tried:

• Updated OPNsense to latest version
• Update Ubuntu 20.04
• Same issue with IC turned off as on
• Set a reserved IP for my XPS
• New motherboard incl. cpu, ram, wifi card, etc for my XPS 13 (another reason, warrenty thing, but still, brand new hardware)
• Tried looking in the different log files but nothing*

*I am not a professional network engineer - I manage to setup OpenVPN, FW rules, etc but not on the same level as many on this forum.

Any pointers? I really want OPNsense to work for me - I really like interface and performance.

Big thanks in advance!

Some issue with OPNsense. Vanilla install with IC turned off. Some bug somewhere.

Installed OpenWRT and everything has worked flawless since then (exakt same hardware, network equipment, etc).
