Download limited at 100mbit. Upload unlimited. Would like help figuring out why.

[LesterCLL]

Hello all,

I have upgraded from 100mbit to 1gbit internet. As the title states I am having problems understanding why the download speeds are limited at 100mbit.

My ISP tells me they can see the connection as solid 1000/1000mbit. I have tested speeds on windows and linux systems, and all have the same issue.

Suricata is disabled, ClamAV is disabled, there is no traffic shaping active.

OPNsense 21.7.2_1-amd64
FreeBSD 12.1-RELEASE-p20-HBSD
LibreSSL 3.3.4

I've been at it for 2 days now, but I'm out of ideas. Is my ISP lying or am I too dumb? I hope someone has some suggestions on what I might be able to test to prove either way.

What's your hardware and how is it configured on the WAN side? PPOE?
More information please not just telling what the symptoms are.

I found the problem.

It's ISP side.

A while back we had connection issues and the ISP set our IP to the MAC. I created a new WAN with a Realtek NIC and the problem is gone. Changed it back to the Intel NIC and I have my old IP again, despite flush/renew/release. WAN configuration is DHCP btw.

Send a message to my ISP and we will see. I could also switch the LAN and WAN ports on the Intel NIC. Should also solve the problem.
