Is it possible to change the network name via SOTI?
Have you checked documentations related to Zebra MX for your CC6000 tablets? My gut feeling is that you probably could have higher chance to get such control with Zebra MX.
Maybe my friend and Zebra expert, Matt Dermody, who is very active in this forum, can provide you with more accurate and up-to-date answer. Just wait a few more hours and he should get on-line and respond very promptly.
