Hi,
I have been having the same problem as everyone else with the Intel 6235 Wireless Card on a Dell XPS 12.
At my work place we have Cisco AP's which have been setup to broadcast 3 networks first one is a guest network which is set as unsecured the XPS has no difficulty connecting to this network.
The second one is the main Staff network the majority of devices are set to connect to this which is set up with
- Security Type - WPA-Enterprise
- Encryption Type - TKIP
- Authentication Method - Smart Card or other certificate
802.1X Settings
- Autheticaation Mode - Computer Authentication
- Single Sign On - Perform immediately before user logon
The Dell XPS 12 connects to this network for a short amount of time but normally when moving a large amount of data from a network share locally to the PC it will drop the connection and will not re connect till 1 or 2 reboots.
The other network is setup like so
- Security Type - WPA2-Personal
- Encryption Type - AES
- Advanced Settings - None Selected
I am able to get the Dell XPS on this network and it is fully functional 99% of the time, when it does drop off the network which is rare it will reconnect to the network.
I have also removed the Intel software controlling the Bluetooth and the wireless adaptor so Windows is controling the wireless with the microsoft driver have changed power settings to what was advised in this forum.
I hope Intel find this information useful in some way!
Thanks
Lee
