Hello, I rebooted my server today to access it directly via gui mode. When it started up it didn't have a network connection. The settings haven't changed, but the network interface shows as down. I'm using a Dell R510 with 2 built-in gigabit NICs, but only one is in use. Ths lights are on showing a link and activity on the server and the switch. After trying a lot of things (new cable, different port on switch, tried using bonded mode, tried using DHCP, tried rebooting in safe mode) I tried the flash drive on another computer, I noticed that when setting a static IP address it creates an IP route. I was also able to manually add IP routes. But when I plug the flash drive back into my R510, there are no IPv4 routes showing and I can't manually add one. When I change the ip address and gateway of an interface, no ip route is added automatically either like it did when I was using the flash drive on the test computer. I've only been using Unraid for about a month and am not very familiar with Linux. Anyone have any ideas what's going on?
