So... I'm actually stumped atm. The tldr is that everything is just
stable now on wireless-n mode.............. on all kernels and the
default firmware! I'll go through exactly what I did.... I'm typing this
on on the default 3.19 kernel....

Keep in mind that I installed tlp (and the dkms's for thinkpads).

1. Commented out my workaround 'echo "options iwlwifi 11n_disable=1'" in 
/etc/modprobe.d/iwlwifi.conf
- I just added '# ' in front of that line which was on the last page

2. install the 4.1RC1 kernel:
- http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.1-rc1-vivid/

I restarted here.... Then booted into the 4.1RC1 kernel.

3.  Test the 4.1RC1 kernel with the firmware from the /lib/firmware/ git (the 
not standard ucodes!)
- Ran Speedtest: stable
- Watch Youtube Videos: stable
- open Connection Information fluctuates speeds between 77 Mbps and 150 Mbps
- Conclusion: Wireless N is stable

4. Test 4.1RC1 kernel with the standard /lib/firmware packages
- delete the git /lib/firmware/ reinstall linux-firmware
    - cd /lib/firmware
    - sudo rm iwlwifi-7265*.ucode
    - sudo apt-get --reinstall install linux-firmware
- restarted the computer
- Actual testing
    - Speedtest: success
    - watch youtube: success
- open Connection Information fluctuates speeds between 77 Mbps and 150 Mbps
- Conclusion: 4.1RC1 is stable with Wireless-N

5. Test 4.0.1 mainline kernel with stardard /lib/firmware packages
- speedtest: success
- watch youtube: success
- open Connection Information fluctuates speeds between 77 Mbps and 150 Mbps
- Conclusion: 4.0.1 is now somehow stable with Wireless-N

6. Test 4.0.1 mainline kernel with stardard /lib/firmware packages AND delete 
the workaround commented line
- opened "/etc/modprobe.d/iwlwifi.conf" and deleted the line "# options iwlwifi 
11n_disable=1"
- speedtest: success
- watch youtube: success
- open Connection Information fluctuates speeds between 77 Mbps and 150 Mbps
- Conclusion: 4.0.1 is now somehow stable with Wireless-N

7. Test the standard 3.19 kernel with standard /lib/firmware packages with the 
deleted workaround line
- speedtest: success
- watch youtube: success
- open Connection Information fluctuates speeds between 77 Mbps and 150 Mbps
- Conclusion: 3.19.x is now somehow stable with Wireless-N

So yes.... Apparently my wifi is magically stable! I cannot give you an
explanation at all, so I apologize why this would just magically
work......... Maybe the first install of linux-firmware was just messed
up? Or maybe installing tlp and its modules did something?

What else do you need here because honestly I'm stumped...
