[Kernel-packages] [Bug 1673344] Re: Ubuntu 16.04 doesn't recongnize wifi card after loosing signal completely (intel 7260) even when I try to restart network manager
Final update on this. It turned out that using the 2.4 Ghz band was much more stable than 5 Ghz, which got wedged within minutes, but conditions eventually worsened until even on 2.4 Ghz without much internet usage it would get wedged every few hours. I then tried out various kernel versions on 16.04 LTS going all the way back to 4.4.9 and different versions of iwlwifi ucode with no success and different variations of dmesg output, even though I recalled the wifi working just fine back before upgrading to 17.10. Looking through other bugs, this one is very similar https://bugzilla.kernel.org/show_bug.cgi?id=191601 and there is a script that worked for me to reset the wifi without having to reboot, which was a major improvement. Clearly there wasn't a specific recent software change in Linux that caused this issue. Other people reporting this bug have reported it cropping up at different OS/kernel versions. The wifi still works perfectly fine on Windows 10, and the script to remove/re-add the PCI card via sysfs can recover the wifi. Based on all of these facts, I believe this is a longstanding hardware-software bug in Linux where it can't recover from certain conditions when there is hardware degradation on the PCI card - perhaps some timeout deadlock - that Windows either shrugs off or can recover from. Based on that hunch, I ordered a new 7260 half height PCI-E card, replaced it in my desktop, and wifi has been working perfectly since (a week or so). At this stage, this card is very old and no specific bug can be easily pinpointed. Furthermore it requires a somehow hardware degraded 7260 card to reproduce so a fix will be unlikely. In my opinion it is your best shot to buy a replacement 7260 card to tide you over until you upgrade your PC. ** Bug watch added: Linux Kernel Bug Tracker #191601 https://bugzilla.kernel.org/show_bug.cgi?id=191601 -- 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/1673344 Title: Ubuntu 16.04 doesn't recongnize wifi card after loosing signal completely (intel 7260) even when I try to restart network manager Status in linux package in Ubuntu: Confirmed Status in linux-firmware package in Ubuntu: Confirmed Bug description: My wireless connection completely disappears and isn't recognized along with my NIC card and doesn't come back until I reboot even if I restart network manager.

Also now experiencing this bug after 17.10 upgrade - never had a problem before. Wifi still works fine on the Windows side of dual boot so probably software issue. Messing with swcrypto, rfkill, power management off, WOL off doesn't seem to have any effect. I tried different older ucode versions from https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux- firmware.git but the problem still exists, although the oldest 7260-17 ucode version on the git tree doesn't continually spam errors to dmesg after the initial failure, just once for the initial failure. One strange thing I noticed is that stability is much worse with an active deluge (torrent client) process, in which iwlwifi wedges after hours->a day. But with deluge off it can last for multiple days - maybe indefinitely - without wedging. -- 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/1673344 Title: Ubuntu 16.04 doesn't recongnize wifi card after loosing signal completely (intel 7260) even when I try to restart network manager Status in linux package in Ubuntu: Confirmed Status in linux-firmware package in Ubuntu: Confirmed Bug description: My wireless connection completely disappears and isn't recognized along with my NIC card and doesn't come back until I reboot even if I restart network manager.

I'm sorry, but this new kernel is much, much MUCH worse than the old one as now my system is completely unusable. With 16.04 when the Intel network adapter gave out I could at least switch to one of my other ones. But with 18.10 neither the Ralink nor the Realtek work. They are both "active" and can see various wireless networks, but they both completely fail to connect to ANYTHING So now when my Intel adapter goes down, I'm forced to reboot.

Against my wishes I've updated to 17.10 along with the kernel and drivers that come with it. And it still fails. Works for a few minutes then goes permanently to a "Device not ready" until the next reboot. But now it's even worse because it also trashes every single other wifi device I have. When that one fails, my Ralink 802.11g WLAN also becomes "Device not ready". And my Realtek 802.11n WLAN Adapter also becomes "Device not ready" However, running dmesg gives a completely different reading: "iwlwifi :03:00.0 Could not load the [0] uCode section" "iwlwifi :03:00.0 Failed to start INIT ucode: -5" "iwlwifi :03:00.0 Failed to run INIT ucode: -5" So...what?
