Hello champs
I'm facing a strange issue, where whenever I am using qBittorrent and setting a speed limit above 5-6 MB/s, the LAN interface stops working.
I have an OPNsense box running on a Dell OptiPlex 3020 with a CPU Intel(R) Core(TM) i5-4570 CPU @ 3.20GHz (4 cores, 4 threads), 8GB RAM and 128GB SSD.
The WAN interface is assigned to the integrated NIC on the mobo while the LAN interface is a RTL8111/8168/8211/8411 PCI Express Gigabit Ethernet Controller
Running ifconfig down/up all comes back to normal.
When crashed, I am not able to ping the LAN interface or to ping the LAN from the opnsense box.
Anyone had similar issue or any clue where to look?
Thanks in advance
Vincent
most likely the usual Realtek problems.
Short of it if you're new to it, realtek nics fail under stress.
You could try to see if things improve a bit with the vendor driver instead of the os one, or -best if you can- replace the nic.
