I just installed Opnsense on my Alder Lake N100 box, and out of the blue it went from 1000mbit on WAN to 100mbit...I rebooted my opnsense and resat my ONT, still "Media" was 100mbit....I selected the portspeed from "Auto select" to 1000 mbit full duplex", rebooted and got the right portspeed...all was good. I now tried to reverse back to "Auto select" and rebooted once more, and now it got it right, the port negotiation was correct, 1000mbit full duplex.
Is this a Alder Lake issue or??
My NICs are Intel 226V, 2.5mbit
Thanks
Cabling issue is more likely
Check your cables.
Thanks guys
I dont know why I didnt think of that, I changed the cable...just in case, It did work before after i did as I wrote before, but maybe it is a bad connection in the cable...thanks again 🙂
