Hello,

I recently changed my ISP and upgraded to 10gb fiber and ever since the upgrade every time I plug in the modem connection to my router, it becomes inaccessible and unresponsive from any web client. It was working briefly when it was first installed but about 30 minutes later my whole network went down. While troubleshooting the only times I have access to the web console would be when my modem is not connected to my router so my process has been mostly just fiddling with the WAN interface and checking the logs before I plug it in to see if it works. I have also tried completely resetting the settings but that also doesn't seem to have any affect on my issue. I have also tried lowering the speed and duplex to different speeds and at 100baseTX the web console is at least accessible but I am not able to reach any sites. I have basically narrowed down the culprit to be the pfSense router because my consumer Netgear router is able to communicate with my modem and it works when I plug the ethernet cable directly from my modem into my computer. I am unsure if my system logs are telling me anything relevant to my issue but on the occasion I see the gateaway logs pick up my public IP from the ISP it shows a sendto: error code 50 or 65. Given that the speed duplex change made an impact on the issue's behavior I am inclined to think maybe the NIC I have installed might be the issue bit I think I need some advice on where to go from here. I would preferably like to use the pfSense router I have built so I am trying to find answers as to what else I can do to address this issue.

For reference on what hardware I am using, its an HP T730 and my NIC is an Intel I350-T4.
