Background Info, how the problem came about:


	I am writing on behalf of a customer/friend who I've wiped Windows 7 in yet another ugly mess that I come across often (Windows in general), backed up user files' and reinstalled with “13.10, Saucy Salamander”. I myself run Gentoo, but it's not for everybody. I will get straight to the point. He wants his Locomotive Train Simulation Games to work. I do not like the idea of him running Windows software under Linux (WINE), and know that can be buggy as well working half-*** or not at all.

        So what I did is, I took a Linux Live DVD (USB actually) and ran
Gparted, resized the only partition (1 Primary, no swap needed with the
amount of ram), and made the free space before the Ext4 Partition for
Linux, and placed an NTFS Partition that would be /dev/sda1. I am doing
everything possible to prevent the Windows installer from doing anything
to wipe out Linux.

        I then went to installing Windows 7. Upon reaching the
partitioner, it recognized the newly created NTFS Partition, and I had
it install there. Yes, knowingly, it would wipe out the MBR of Grub2
with it's own BS that I later fixed using some Gentoo skills (refer to
the Gentoo Handbook if interested).

Skip ahead...

Windows 7 and Linux are now both dual booting just fine with Grub2.
However, a problem exists with Wifi working under Linux. I have a couple
of options:

1. Solve the problem myself, reconfigure make menuconfig, patch if necessary, etc. etc., or
2. Make a bug report, so that when updates come in through Ubuntu Repositories, the issue is fixed and remains fixed not only for this customer, but all others that run into the problem and would run into the problem if a bug fix had not been made.


Problem in More Detail:


Boot Linux to GUI desktop. Automatic connecting to the WPA2 Wireless Network by Network Manager does not happen. Then go into Network Manager's Settings and find out 

Airplane mode is enabled. It will toggle off. Wireless is toggled off,
and refuses to toggle on.

Temporary workaround that gets around the issue:

Suspend the computer in Linux (did so through the GUI), and wake it from
Suspend. Now everything works and behaves as expected, but the problem
will persist after a reboot.


Troubleshooting:


Check dmesg!!!!!!!! # // /* Attachment of dmesg output below */
	sudo passwd root
	su -
mike-HP-Pavilion-dv7-Notebook-PC BugReport # rfkill list
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: Yes
	rfkill unblock wifi     # Check with list again, same results
	rfkill unblock all        # Same as above
	rfkill block all
	rfkill unblock all        # Same results still persist
	halt/poweroff/reboot
	# Booted back up in no time on this ssd drive, command line again
	su -
	dmesg > dmesg_before
	# Suspend work-around mentioned earlier
	dmesg > dmesg_after
	# Examine with the best editor known to existence, SORRY EMACS FANS!

Notice besides the huge backtrace of call stack (that can point right to
where the problem lays in code) that a specific firmware refuses to be
loaded.

mike-HP-Pavilion-dv7-Notebook-PC BugReport # locate rt2860.bin

Through Googling, as well as checking other bugs on launchpad.net
(Nothing of much relevance found), I came across this page as being the
most relevant with best given advice I've found with a few exceptions:

https://ubuntuforums.org/archive/index.php/t-2178085.html (renders
differently with ssl)

Gentoo:
https://forums.gentoo.org/viewtopic-p-7394590.html (deals with the same firmware rt2860.bin, rfkill probs, but rt2800pci is already compiled as a kernel with generic kernels such as Ubuntu's, different patches, Ubuntu patched craziness especially with drivers more so than debian from vanilla kernel, different kernel versions, no NetworkManager running on that Gentoo Box)

Conclusion:

Throw Windows out the Windows. See attachments I provided. I can provide
much more debugging info, apport if you want, but no sensitive
information. No problems are seen in the bios, set to default, reboot,
nothing, remove “splash quiet acpi=off” from kernel boot line, nothing
(but it'd only be used to more narrow down the problem anyways), did the
following

mike-HP-Pavilion-dv7-Notebook-PC BugReport # cd /etc/NetworkManager/system-connections/
mike-HP-Pavilion-dv7-Notebook-PC system-connections # rm -vf *

As well as:

service network-manger restart
apt-get install --reinstall network-manager network-manager-gnome
apt-get --purge remove network-manager network-manager-gnome
apt-get install network-manager network-manager-gnome

Right now the work-around is in place as I'm typing this and collecting
info. If you want same info while the bug is being reproduced, I can
provide that as well.

It's getting late. I'm sleepy. If you need more debugging info, I'll be
glad to provide it.

Thank you,
