[Kernel-packages] [Bug 1451246] Re: Intel 7265 Wifi instability workaround
XicoSM, please check the first comment. Do all the steps I did there by ensuring the latest intel ucode, kernel (I'm using 4.0.2 now btw), and the WORKAROUND which disables wireless-n. See if that stabilizes your wifi.. After that, read comment #6: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1451246/comments/6 tl;dr I commented out the line to disable wireless-n (which re-enables it) and somehow my wifi is 100% stable.

[Kernel-packages] [Bug 1451246] Re: Intel 7265 Wifi instability workaround
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?
