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?
