[Kernel-packages] [Bug 1584533] Re: Lenovo X220 unable to wlan after resume from sleep
In the mean time, there was a linux kernel upgrade in Ubuntu 16.04, and whatever that kernel changed, I have not had connection failure ever since. I would therefore cautiously mark this issue resolved for now. About the suggested BIOS upgrade: there appears to be something messed up on Lenovo's webpage: while version 1.42 is stated as available, the download links provided on that page will provide version 1.40. One has to guess the correct download URL to access the most recent BIOS version: BIOS version 1.42: https://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/8duj27us.exe Description: https://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/8duj27us.txt -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1584533 Title: Lenovo X220 unable to wlan after resume from sleep Status in linux package in Ubuntu: Incomplete Bug description: I just upgraded to Ubuntu 16.04, and now whenever I wake up my laptop from sleep (hibernate doesn't work due to encrypted home directory), I am unable to connect to any wlan network.

Dear Christopher, thanks for your feedback. Following your suggestion I upgraded to the latest BIOS version provided by Lenovo, here is the output from this 'sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date' line: 8DET70WW (1.40 ) 05/14/2015 Sadly, there was no improvement on the bug, I still get situations where my laptop won't connect top WLAN and will refuse any attempts to force it to short of a reboot. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1584533 Title: Lenovo X220 unable to wlan after resume from sleep Status in linux package in Ubuntu: Confirmed Bug description: I just upgraded to Ubuntu 16.04, and now whenever I wake up my laptop from sleep (hibernate doesn't work due to encrypted home directory), I am unable to connect to any wlan network.

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. Also, you don't have to create a new bug report. Once the BIOS is updated, if the problem is still reproducible: 1) Please provide the output of the following terminal command (not perform an apport-collect): sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 2) Please make a comment specifically advising on if there was an improvement or not. 3) Please mark this report Status Confirmed.

[Kernel-packages] [Bug 1584533] Re: Lenovo X220 unable to wlan after resume from sleep
Thanks for your reply, before I followed your recommended steps I did a system upgrade as recommended by ubuntu update manager. Since this also updated systemd which is AFAIK pretty basic to the system, I tested both after the upgrade AND after the switch to this mainline kernel you recommended. Behavior became much stranger with the regular system update, and in both cases (i.e. ubuntu kernel and mainline kernel) the system behaved more or less the same, as far as wlan is concerned: - After a reboot everything looks normal, wlan comes on even before login, and stays intact after login. network manager applet in top bar shows wlan networks plus the one I am connected to. - After a sleep/wakeup, network manager shows loss of wlan connection. No existing wlan networks are shown in wireless network list. Opening "connect to hidden network" menu lists all networks I ever connected to, but will not allow me to hit connect with any of them in the list, connect button is grayed out. - Now here comes the freaky part: in SOME of these instances I am actually connected to my home wlan! This is not shown directly in network manager, only after opening connection information window one can see that there is a virbr0 device, and an active wlan0 device. After many reboots and sleep/wakeup cycles with both kernels (ubuntu and mainline), I can state that there is about a 50% likelyhood that wlan becomes active, and that if wlan is active after one sleep/wakeup cycle, chances are high that it will work in consecutive sleep/wakeup cycles. In two cases (one for each kernel) I could create a special case: wlan active after reboot, active again after sleep/wakeup, then inactive after next sleep/wakeup. Since these cases yield a very compact dmesg file, I post both of them here. I hope this helps pinning down the issue, please let me know if you need further data or tests.
