RE: Dell XPS 13 9360 - BIOS v. 2.4.2 breaks UEFI Network Stack Ability
After speaking with support on this, we are having an onsite technician come and swap out 30 motherboards for us to get us back to the 1.3.7 version of the BIOS.
Seems like a waste of time and money for Dell rather than simply fixing the BIOS, but hey.....that's why we pay for support. If it takes him days to do it, then so be it.
So if anyone else runs into this, request a new motherboard be swapped in.
