Would someone be so gracious as to detail the workaround for this bug until it is fixed? I disabled secure boot and tried to build Core18 using instructions from the wireless.wiki.kernel.org page but I still have firmware 16.242414.0 and my WiFi continues to disconnect. Here is a summary of the steps I followed:
cd /tmp/ git clone https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git -b release/LinuxCore18 cd backport-iwlwifi/ make defconfig-iwlwifi-public sed -i 's/CPTCFG_IWLMVM_VENDOR_CMDS=y/# CPTCFG_IWLMVM_VENDOR_CMDS is not set/' .config # see web page subheading "About vendor commands" make -j4 sudo make install # displayed lots of SSL errors # reboot It appears that I have the updated module but it's not getting loaded: $ sudo find /lib/modules/$(uname -r) -name iwlwifi.ko -ls 1244072 352 -rw-r--r-- 1 root root 359590 Oct 26 23:29 /lib/modules/4.4.0-47-generic/kernel/drivers/net/wireless/iwlwifi/iwlwifi.ko 1305660 536 -rw-r----- 1 root root 545328 Nov 14 18:55 /lib/modules/4.4.0-47-generic/updates/drivers/net/wireless/intel/iwlwifi/iwlwifi.ko -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1577800 Title: Frequent disconnects with Intel 8260 wireless NIC Status in linux package in Ubuntu: Incomplete Status in linux-firmware package in Ubuntu: Triaged Bug description: This issue has been resolved upstream and is described in https://bugzilla.kernel.org/show_bug.cgi?id=117391 The current Ubuntu Xenial Xerus kernel (4.4.0-21.37) is built with a version of the iwlwifi driver which supports firmware version up to iwlwifi-8000C-19.ucode. However, the matching linux-firmware package ships with the -16.ucode version of the firmware, which contains this bug. The next stable version of the firmware after -16.ucode is -21.ucode, but is not supported by the version of the iwlwifi driver in the 4.4.0 kernel. In order to fix this issue, either the minor version of the firmware (-19.ucode) needs to be included in the linux-firmware package or the iwlwifi driver in the kernel package needs to be upgraded with a backport of the iwlwifi driver new enough to support the -21.ucode firmware.
