1. A vehicle comprising:
a plurality of network controllers; and
a wireless local area network (WLAN) over which at least a first network controller and a second network controller of the plurality of network controllers are to communicate, the second network controller to store device profiles and credentials,
wherein a link between the first network controller and the second network controller through the WLAN is a synchronized link,
wherein the first network controller is to be powered off in response to the vehicle powering off, and the second network controller to store the device profiles and the credentials remains operational when the vehicle is powered off wherein the first network controller comprises a first clock to produce a first oscillating signal, and the second network controller comprises a second clock to produce a second oscillating signal, wherein the synchronized link is based on the second oscillating signal having transition edges that are aligned in time with transition edges of the first oscillating signal, and
wherein the first network controller comprises a first clock to produce a first oscillating signal, and the second network controller comprises a second clock to produce a second oscillating signal having transition edges that are aligned in time with transition edges of the first oscillating signal.
