Hi,

I got report from people that on Intel Centrino N1000 wifi won't work after
updating to 3.17.8. I see in that release Fedora maints enabled POWERCAP and
INTEL RAPL. We got working wifi only after disabling powersave via iw dev wlp2s0 set power_save off.

How we can debug this?

lspci above.

What kernel version did you have before?
BTW - for this device, power save is supposed to be disabled by default, but I need to check
