Unable to Obtain IP

[jmail]

Hi,

I have a 4 NIC NAS. Suddenly one of my ports is not being assigned a valid IP address. The other 3 work just fine.

Things I've tried:
Router is configured to assign DHCP.
All 4 ports are plugged into the same switch.
Resetted the NAS
Reassign the NIC in Virtual Switch Manger.

Any help please?

Thanks

nas model and firmware ?

nic has a valid mac address?

tried fixed ip instead of dhcp?

Model: TS677
Firm: 4.3.4.0597

The mac should be valid. Especially so since I just reset it the system.

I assign a static IP but I still cannot reach the internet.

Thanks

anything visible on the router?

is the link up ? (change port or check cable)

dhcp log (cannot give lease to 00:00:00:00:00 .. for broken mac)

Changed cable?
