Wifi Card Not Recognised by any interface.

I have recently upgraded my Motherboard (to the MSI Mpower Max AC) which came with an Intel 7260 wireless card.
This card appears in lsusb -v with the linked output. http://pastebin.com/mSP9w1A8

However, it does not show up in iwconfig (only shows eth0 and lo).
Wicd states that it is scanning, but does not finish.
rfkill shows the bluetooth component of this, but not the wifi.

Linux-firmware is installed. dmesg has no output, but journalctl | grep iwlwifi gives the following: http://pastebin.com/GFMdX7ts
I am currently running kernel 3.15.5-2.

I have no idea where to go from here. Any help would be greatly appreciated.

Thanks.

Re: Wifi Card Not Recognised by any interface.

The specs list both pcie and usb interfaces and your lsusb output only includes bluetooth.  Could the bluetooth use usb while wireless uses pci.  I don't know if this is possible, but it's worth checking `lspci -vnn | grep -i net`.

I found a different forum discussing this card about a year ago when it was brand new.  They had found that iwlwifi needed to be recompiled to include experimental stuff to get the 7260 included.  I see via `modinfo iwlwifi | grep 7260` that this is now included in the arch default build (it may have been for some time as that was a year old thread).  But this confirms that the card should work with iwlwifi.  Can you ensure that this module is loaded: `lsmod | grep iwlwifi`.

Re: Wifi Card Not Recognised by any interface.

Just took a look then, and found the following:

lspci -vnn | grep -i net gives no output.

The firmware is included in my system as well.

The module was not loaded, but now is. No change in it's ability to work.

iwconfig still only shows eth0 and lo, both with "no wireless extensions".

In regards to bluetooth, I have also not been able to get it to work. However, unlike wifi, it shows up when given a command such as rfkill list.

Thanks.

Update.

Still having trouble with it, however, I am now thinking it is part of a slightly different problem.

According to this post: http://forums.gentoo.org/viewtopic-t-98 … art-0.html
There is something else failing, which means that the driver isn't able to load. Though I have no idea what is failing, nor how to fix it. The issue is pci_enable_msi is failing.

Any help would be appreciated.
