Hi all, I’m in need of some help here. No idea what’s causing this bizzare issue.
I use to use OpenWRT on a variety of routers, but I wanted to gain a bit more networking knowledge with Pfsense and OPNsense. I went with OPNsense for the GUI.
For the most part it’s been a breeze. I wanted something low-power, so as many reccomended it I went with a thin client specifically the HP T620 Plus as I could put a quality gigabit NIC in it.
For my NIC I went with a HPE NC364T which I chose because it uses two Intel 82571EB controllers.
After putting OPNsense on it I was blown away, really great software and actually improved my connection speed despite the firewall.
That was until I restarted it and my modem after a couple of days, suddenly it didn’t want to pick up a WAN IP (DHCPv4).
What was weirder was that it also didn’t allow me to reach the router from the LAN. But the lights were on, on both ports and were occasionally flashing.
After much troubleshooting, the only remaining possibility was a bad NIC. This seemed to be correct as I bought an identical NIC and after installing it everything returned to normal for weeks.
Yesterday I restarted it and my modem and OPNsense for something unrelated. Exactly like last time it failed to pick-up a DHCPv4 WAN address and it’s unreachable over LAN.
The only thing it can ping is itself. Even with my PC directly connected into it. It still lights up and occasionally flashes the port.
I’ve even switched back to the old NIC and it’s doing the same (though with the old NIC there’s this odd whine sound).
What I don’t understand is why it has worked for literrally weeks until this moment. I’ve restarted just OPNsense (not the modem) several times for updates.
Do I just have the worst luck ever with NIC’s or is there possibly something else going on here? I don’t really want to have to buy a new NIC every time I restart my kit .
