@Tom-Elliott No STP connection, however, I forgot to mention, that I’m using Proxy-DHCP as I cannot access the DHCP. It’s a Meraki setup and the networks are managed by a centralised OU. This, again, is not causing any trouble with any other device. I even got some legacy rom machines that are well-behaved.
I cannot see any power saving settings, that may interfer.

G’Day!

I’ve got problems with PXE booting a Dell Latitude 3500. This piece of … nice technology … is the last computer here that is refusing to register to fog.
Of course, I have used the search function and of course I did a thorough Google Search. However, none of the mentioned solutions did work for me.

So: The BIOS is configured with UEFI stack enabled, Secure-Boot off and Fast-Boot on thorough. When booting from NIC it is downloading the NBP file successfully and then it stops - no loop or anything, it just stands still.
I updated the bios to the current version. I tried any of the available boot files in tftpboot and tracked that the correct file was being downloaded. Then I tried to use an external LAN-adapter with which I successfully deployed a Dell Latitude 7430.
No success at all.

Anyone got an idea?

Thanks!
