This is a well known issue with Intel WiFi adapters (on both Linux and Windows). The only reliable workaround I've found is to disable 802.11n: 1. Open terminal. 2. sudo vi /etc/modprobe.d/iwlwifi-disable11n.conf 3. Add this line: options iwlwifi 11n_disable=1 4. Save and restart. I've had this issue on 3 laptops, all with the Intel 7260. Disabling 802.11n made the connection stable on all of them (i.e no more frequent sporadic drop-outs). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1262388 Title: 8086:08b1 [Toshiba Satellite P55-A5312] Intel 7260 Wifi regularly crashes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1262388/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

penalvch, I've been running with the iwlwifi patch + the new 22.1.7.0 7260 firmware for the past few days, and I haven't seen a single error written to dmesg, ie. it's been running flawlessly! Therefore, unless you'd like to test further, please feel free to close this issue! Following adrien-loxq's success with the new 22.1.7.0 firmware in comment #36 , I would greatly appreciate it if both this 7260 firmware and the iwlwifi patch were pushed into an official Ubuntu release.

penalvch, thank you for your patience. The URL in your last post looks to be for the 3160 card, whereas I have the 7260. So I have instead downloaded the version from http://wireless.kernel.org/en/users/Drivers/iwlwifi?action=AttachFiledo=gettarget=iwlwifi-7260-ucode-22.1.7.0.tgz, and upgraded my driver to this version. I will report back progress in due course. Please note: despite there not being 100% success with just the fix applied to the kernel, it still appeared to make my wifi connectivity much more stable than previous. Therefore, in my view, it is still a valid fix -- and should be promoted into an official kernel release.

Keeping everything else the same, please do update the firmware to http://wireless.kernel.org/en/users/Drivers/iwlwifi?action=AttachFiledo=gettarget=iwlwifi-3160-ucode-22.1.7.0.tgz and we can see if it gets better or worse in comparison to your most recent test. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1262388 Title: 8086:08b1 [Toshiba Satellite P55-A5312] Intel 7260 Wifi regularly crashes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1262388/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1262388] Re: 8086:08b1 [Toshiba Satellite P55-A5312] Intel 7260 Wifi regularly crashes
penalch, I've been trying this custom kernel for the past 2 days, and I've yet to notice any wifi disconnects or errors in the log. NOTE: This is with the original 10/21/2013 firmware, too. I'll monitor wifi stability over the next week or so -- and will report it if I find further issues -- but so far this customized kernel's done its job and been a success! I'd appreciate it if you could coordinate the commit mentioned previously here into an official kernel release for 14.04.

penalvch, I apologize for the delay getting back to you. A couple days' ago, I tried making the wireless backport code for 3.12, but I immediately got several errors in the C compilation. I am sorry, but I can't give you the errors right now as I'm at work, but I remember they were to do with a set of undeclared #define's...? I'm being vague here, and I'll get you a listing of the errors later on. Because i could not build the backport, I did as Roman has done here and upgraded my 7260 firmware to 22.1.7.0. The stability of my wifi connection is much better now, and I have yet to experience another crash in ieee80211_reconfig as I got before. If you can help me fix the backport code, I am happy to revert back to the original firmware from 14.04, and then install the backport as you suggested. But I suspect the issue is with the 7260 firmware itself. Note that I discovered this bug fix made a month ago to the firmware driver to fix an interrupt issue in there: http://git.kernel.org/cgit/linux/kernel/git/iwlwifi/iwlwifi- fixes.git/commit/?id=6960a059b2c618f32fe549f13287b3d2278c09e9 It may be worth pointing developers at this link, so they are aware of the bug fix.

[Bug 1262388] Re: 8086:08b1 [Toshiba Satellite P55-A5312] Intel 7260 Wifi regularly crashes
I am sorry for the ambiguity. I initially installed an official 13.10 release (totally wiping over my previous 12.04 install). But the first time I checked for updates, it immediately upgraded me to 14.04 -- even though the System About box from the gnome desktop still tells me I'm on 13.10! I assume I am now on Trusty/14.04. Is there any way to 100% verify which release I'm officially on? As for a pure 13.10 install, I ran a 13.10 release from CD over the weekend for a number of hours, and I did not get any wifi disconnect or crash at all. However, the same could initially be said for my 14.04 install before I got the crash last night. Here, the wifi error just happened once, whereas before the error happened over and over again. Would you like me to temporarily try a newer version of the 7260 firmware? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1262388 Title: 8086:08b1 [Toshiba Satellite P55-A5312] Intel 7260 Wifi regularly crashes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1262388/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

JamesE, thank you for the requested information. It is understood that when you test the live environment of both 13.10 and 14.04 it works, but when installed and it crashes. Given that according to http://wireless.kernel.org/en/users/Drivers/iwlwifi your card is supported on kernel series 3.10.x+, it would be helpful if you tested the compat-wireless/linux-next development branch noted in https://wiki.ubuntu.com/Kernel/LinuxWireless#Compat- wireless_from_upstream .

I'm not sure I would say it 100% works in the 13.10 live environment. I just noticed that iwlwifi didn't crash while testing for a number of hours. Even when the crash did occur on my installed 14.04, I'd been running it without crashes for a significantly longer period of time than the live 13.10. I have gone to http://drvbp1.linux-foundation.org/~mcgrof/rel- html/backports/ (for linux-next upstream backports), and downloaded the tar file for backports-3-12.2-1. However, I notice most of it is .c and .h source code. I'd appreciate it if you could tell me how can I install this tar file into my system. Sorry if I seem a bit thick at this point!

Christopher, thank you for your reply and help here! My plan is to upgrade to the official 13.10 release, and check over a longer period of time whether I still get any wifi disconnects. If I find a problem, I will raise a new issue and notify you of it. Note I will keep with the 7260 firmware as installed by 13.10 -- at least for now. Please note there has been reported a recent spate of instability issues using the Intel 7260 board with Ubuntu, and at least in my case, my problem was fixed (or at very least, greatly reduced) by moving from 12.04, which does NOT support the 7260, to 13.10 which DOES support it. It may be worth recommending this course of action to others.

[Bug 1262388] Re: 8086:08b1 [Toshiba Satellite P55-A5312] Intel 7260 Wifi regularly crashes
I downloaded and tried (via the ISO image) Ubuntu 13.10, for about a few hours, and the wifi connection held up fine without any disconnects. Maybe 13.10 really does fix the issue -- or maybe I just need to try testing it more? But 13.10 uses kernel 3.12, whereas I have installed kernel 3.13 on my hard drive where I am experiencing the disconnects. It's unlikely kernel 3.13's regressed -- so maybe the problem really is in the 7260 firmware?? What's weird is that I diff'd a copy of 13.10's 7260 firmware against what the firmware I'm using on kernel 3.13 (that disconnects), and both appear to be identical. So, if the kernel's not regressed and the 7260 firmware is the same, I cannot explain why wifi connection appears to be stable under 13.10, but not under 12.04 with kernel 3.13... To make matters more complicated, I've just gone back to http://wireless.kernel.org, and now find someone's put up a new version of the 7260 release 7 firmware! The full 7260 firmware version is 22.1.7.0 whereas I'm sure it was 22.0.7.0 a couple days' ago... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1262388 Title: 8086:08b1 [Toshiba Satellite P55-A5312] Intel 7260 Wifi regularly crashes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-raring/+bug/1262388/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.13-rc4 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed.

Thank you , Christopher. As I noted in the bug report, I did install the mainline kernel 3.13 yesterday, and although the firmware crash still occurs, it appears there is restart logic in iwlwifi to restart the connection automatically. Beforehand, I would have to use rmmod and modprobe to reload iwlwifi manually. In fact, I noted this restart happening just before I reported the issue. My gut feeling (not very technical!) is that the root cause is probably in the 7260 firmware code. Please note that I am using the latest version -- version 7 -- for the 7260.
