We have roughly 180 C710 Chromebooks in our school. In the last few months we have noticed a lot of connectivity issues with our network. Cisco is telling me that the Chromebook's wireless drivers are failing to respond to the M5 key which is used during the authentication process. This key is ratated every hour with the system. Does anyone know of any fixes for these Chromebook wireless drivers or is just the Chromebooks coming to end of life. They were purchased in 2013. Anyone else having an issue with wifi on these. Sometimes the Chromebook shows a connection but isnt really connected to the internet and sometimes it just drops the network completely.
