I had an Intel NIC to avoid the onboard Realtek but wanted to add a new GPU to handle transcoding and the GPU needed the slot. After removing the NIC, I switched the network settings over and had internet and LAN access last night. After waking up this morning, I restarted the machine and now internet access is gone. I can still log in to the machine on the LAN, but I do not have any internet. These are settings I know very little about, so I'm positive this is just something I need instruction to setup properly.

Remove the gateway from eth1, only eth0/br0/bond0 should have a gateway set

Under Routing Table? I’m only showing docker0 and eth0 there. Docker0 was not there last night when I removed the NIC but was there this morning when I restarted.

Edit: looks like the routing table reverted back from the changes I made last night. I’m unable to delete, modify, or add any new routes though. How do I make changes here?

Well, whatever changes I made caused me to lose LAN access.

You are on an old release; it has phantom settings for eth1 which no longer exists. This should not happen with the latest releases.

You can remove them by manually editing /config/network.cfg on the flash drive and changing this:
