intel 4239 WiFi card not working with iwlagn

[Ákos Maróy]

Binary package hint: linux-image

on a new HP Envy 15 laptop, the built in intel 4239 WiFi card is just not working. the NetworkManager UI says 'device not ready' (no, its not turned off, then it says its turned off)

lspci -v says:

03:00.0 Network controller: Intel Corporation Device 4239 (rev 35)
        Subsystem: Intel Corporation Device 1311
        Flags: bus master, fast devsel, latency 0, IRQ 35
        Memory at d3000000 (64-bit, non-prefetchable) [size=8K]
        Capabilities: <access denied>
        Kernel driver in use: iwlagn
        Kernel modules: iwlagn

this is on an 9.10 amd64

The Wireless hardware is an Intel Centrino Advanced-N 6200 AGN
