please upgrade your firmware. You are not using the latest -9.ucode available. Please take the latest -9.ucode firmware from here, and let me know if it helped: https://git.kernel.org/cgit/linux/kernel/git/iwlwifi/linux-firmware.git/plain/iwlwifi-7260-9.ucode The issue persists with the latest firmware version 25.228.9.0. Please see new dmesg and journalctl logs attached. Hardware probe of notebook with updated firmware: http://hw.rosalinux.ru/index.php?probe=674fff14a9 Created attachment 168251 [details]

Ok - can you record a wireless sniffer capture of the issue? I'll close the bug in a couple of days if the required data is not provided. You'll still be able to re-open the bug once you have the data. Hi, I am having the exact same problem under up-to-date Arch Linux (same wireless card, Lenovo T440s): % uname -a Linux Phyks-laptop 3.19.2-1-ARCH #1 SMP PREEMPT Wed Mar 18 16:21:02 CET 2015 x86_64 GNU/Linux However, in my case, I can connect sometimes to network, and sometimes it fails. I did not find any special case in which this happens. What extra info would be useful for this bug ? I'll try to post them next time I have problems. please open a new bug and attach the full dmesg output. You should also make sure you have the latest firmware installed. thanks. (In reply to Emmanuel Grumbach from comment #7) > Ok - can you record a wireless sniffer capture of the issue? I've tried to capture the traffic with wireshark program (selected wlan0 in Capture/Interfaces), but it reported: "As no data was captured, closing the temporary capture file!" The wireshark works properly on other WiFi card. Are there other ways to capture the packages? You need to use Wireshark on another WiFi card - not the 7260 and you need to properly set the channel. You can look at https://wireless.wiki.kernel.org/en/users/documentation/iw?s[]=monitor for a few pieces of info. Before you do that, I'd recommend to use the latest firmwares that we have released: -10.ucode and -12.ucode. If you use 3.19, you can use -12.ucode. You can get them from here: https://git.kernel.org/cgit/linux/kernel/git/iwlwifi/linux-firmware.git/tree/ or from here: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi#firmware please re-open when you have the data. The card has accidentally started to work with the old firmware (25.222.9.0) after latest OS updates (the kernel is the same - 3.14.33). Unfortunately, I cannot identify the change that fixed the problem.
