Wifi card not recognized after reboot.

I've got a Lenovo X140e and an Intel wifi card. (Intel Corporation Wireless-N 7260) that I installed myself, since the support for the Broadcom card it came with was spotty.

If I reboot my laptop, the card won't show up with either iwconfig or even lspci. If I do a cold reboot (power down entirely and start back up), it will show up just fine.

What gives?

Relevant lspci output:

01:00.0 Network controller: Intel Corporation Wireless 7260 (rev 4b)
        Subsystem: Intel Corporation Wireless-N 7260
        Flags: bus master, fast devsel, latency 0, IRQ 38
        Memory at f1300000 (64-bit, non-prefetchable) [size=8K]
        Capabilities: <access denied>
        Kernel driver in use: iwlwifi
        Kernel modules: iwlwifi

Re: Wifi card not recognized after reboot.

When the card is recognized, rfkill lists it as unblocked; when it's not recognized, it doesn't show up at all.

I've got i3 installed; for connection management I've been sort of trying different things - netctl never works but wifi-menu has been pretty reliable. I haven't installed any special power management stuff at all - I'm not really sure how to find out what was auto-installed?

Re: Wifi card not recognized after reboot.

Info about your config is now OK (I was affraid it is Gnome or KDE with some power policies). Could you look through this topic and see if it is not Fn + Wifi ? https://bbs.archlinux.org/viewtopic.php?id=194239

Re: Wifi card not recognized after reboot.

I'm having some of the same issues on my Macbook right now,

00:00.0 Host bridge: Intel Corporation Broadwell-U Host Bridge -OPI (rev 09)
    DeviceName: SATA
    Subsystem: Apple Inc. Device 011b
    Flags: bus master, fast devsel, latency 0
    Capabilities: <access denied>

I don't why it's denied. It all happened as soon as I reboot my computer this morning. Any ideas on how to fix??
