Very slow upload on J1900 miniPC with 4x i211

[fezixaza]

I've just picked up a second hand mini PC with a J1900 CPU and 4x i211 NICs using the igb driver (motherboard name in BIOS is EC3-BT19D4L) - I thought I was avoiding NICs known to be problematic but it looks like these might be? Or at least in the current version of FreeBSD that OPNsense is based on?

I installed and updated a fresh install and set up Unbound. Everything seems to be working fine but speedtests will drop off quickly shortly after booting (after initially being fine). I'm on a WISP with a 50Mbps download and 6Mbps upload. There is no difference to the direct speed on download tests but the upload goes down to about 200Kbps or will time out. Booting a live Windows or Linux CD on the same hardware results in a full speed connection.

I've been trying to find a resolution but seem to be finding a lot of people hitting brick walls. Is this hardware just unlikely to work out under OPNsense?

Just thought I would try out OpenWRT on the same hardware, it also has very slow upload speed. I see this is mentioned at https://forum.openwrt.org/t/some-i211-weirdness/153385

I've just tried in 23.7 on the basis of the OpenWRT poster's experience, but upload is still woeful.

Hi
Running  Opnsense on similar hardware J1900/4xi211 with no issue.
Looks to me as a hardware problem on that unit.
Hope this helps

Could I ask what your connection speeds are vs what you would expect from your service? I didn't notice a difference browsing, it was only when running speed tests.

I have set up Debian on it to use as a router and I get the full upload speed there.
