Hi All,
 
Chromebook model: XE525QBB
 
I am in a high security environment where WiFi is forbidden, but LTE is not.
 
I know how to get inside these things.  Anyone know where the WiFi (not LTE) cable attaches, so I can unplug it?
 
If not, is there a way in software were I can permanently disable it.  The method must be difficult for the user to figure out, so please do not tell me about settings-->network.  Can I open a shell and mess up and ifcfg file?  A systemd command to disable the WiFi service?
 
Many thanks,
-T

One of the guys over on Chromiun OS Discussion found the WiFi card for me. Looks like all I have to do is remove the battery to get at it.

At 3:24, he removes the LTE radio card, which he incorrectly calls a WiFi card

 

The WiFi card is under the battery, shown at 12:11.

 

Samsung tech suuport told me the WiFi card was on the motherboard
