so i found my wake on lan was having issues after i upgraded to 7.2.4 i found on my realtek card its not getting a dhcp address.. just 169 i figured was cable but tested with a laptop and cable is fine...

if i set the realtek to a static ip give it 30 seconds and i can ping that ip address... turn back dhcp and reboot... as if you dont do a reboot the dhcp doesnt try to get a new ip it just keeps the static ip;.. same with port down and back up

but when you reboot set to dhcp again it comes up with the 169

so something is wrong its not getting a dhcp ip

here is my diagnostics

Definitely not a general problem, so most likely a LAN config issue. Make sure there is only one DHCP server on the network and that the server can actually talk to it.

only 1 dhcp server.. pfsense can wol the server but it cant give the static reserved ip address.. or the dhcp server doesnt work.. but once i manually set ip and set to 24 then boom its back working..

i did notice after i upgraded from 7.1.3 to 2.4 version unraid reported corrupted network-rules... so i deleted and rebooted...

i did google unraid cant get a dhcp and the ai said there are issues with unraid 7.x and if things dont work delete the network.cfg and networks-rules.cfg and let it re reset itself havent dont that yet just the rules...

plus talked about bonding and binding of vms or dockers but everything set for fiber card... so cant figure it out?

the fiber card gets dhcp ip address.. but the onboard cant.. i figured it was a realtek issue and 2.4 version so i installed the realtek driver... but that didnt help then next sugesstion was to reboot the unraid twice after installing driver... but that didnt help

if i plug a laptop in the same port of the server i get a dhcp so i figured it was a driver issue.. i guess i should try the delete network.cfg and network.rules again and reboot and see if that helps?

so definitely something broken in unraid the dhcp is broken

dhcp works with a laptop running windows

when i deleted

network.cfg

network-rules.cfg

rebooted unraid couldnt get an ip on either network card

i restored network.cfg and rebooted

no ips worked just 169

i restored network-rules.cfg and rebooted

i was able to access server again

dhcp vlans dont work when i deleted the configs

when i restored the files the dhcp on vlan restored

so there is something funky going on.. the only difference i know of back prior to 7 is i swaped the interfaces of eth0 and eth1 so thats about it

so something is funky going on

You can try with a different flash drive using stock install, no key needed, to rule out a config issue. If it's still the same, it will be an external issue.
