[Dell Alienware 17 R3] No network devices after suspend and resume

[adin]

I'm on an Alienware 17R3 on Ubuntu 16.04.

The wifi stops working after resume. The problem seems related to https://bugs.launchpad.net/ubuntu/+source/wpa/+bug/1422143, but the solutions proposed there doesn't work. Other seems to have a problem related with the network-manager stop working (like http://askubuntu.com/questions/761180/wifi-doesnt-work-after-suspend-after-16-04-upgrade).

However, in my case the network-manager restarts and stops after the resume. However, there is no device, and thus there is no list of available networks to join.

For example, doing

$ iwconfig
lo no wireless extensions.

while in a normal reboot the wireless card information is printed

$ iwconfig

lo no wireless extensions.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.7 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[adin (adin-rivera)]

I haven't done an upgrade. I tested on the 4.7 kernel and the problem remains.

[penalvch (penalvch)]

adin, to confirm a WORKAROUND, after resume are you able to recover the WiFi if you execute at a terminal:
sudo rmmod ath10k_pci ; sudo modprobe ath10k_pci

[adin (adin-rivera)]

It doesn't work. The network manager is working, but there is still no card.

[adin (adin-rivera)]

1)

$ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
1.2.15
07/07/2016

2) I don't notice any change on the situation. Tested previous suggestions with the new bios but the problem remains.

[penalvch (penalvch)]

adin, to confirm, if you stop network manager, then unload your driver, then load your driver, and then start network manager as per https://wiki.ubuntu.com/DebuggingNetworkManager does this allow it work after resume?

[adin (adin-rivera)]

I can confirm: it doesn't work either.

I needed to do a small change though:

sudo service network-manager stop/start

as

$ sudo stop network-manager
stop: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused

I guess the intention is the same. If I tested it incorrectly please advice.

[penalvch (penalvch)]

adin, could you please provide the missing information from https://wiki.ubuntu.com/DebuggingKernelSuspend ?

[adin (adin-rivera)]

I'm completing the log report:

Which part of the process does the issue occur with, the suspend to ram, or resuming from?
The network interface is not showing, thus no networks appear in the network manager. Consequently, there is no internet.

Please advise how you suspended specifically. For example:

    Shutting the lid of the laptop, which is set to suspend on close.

Please advise how you resumed specifically. For example:

    Lifted the lid

I'm going to attach the log files in the next posts (the interface allows one attachment and the instructions ask for not compressed files)

[penalvch (penalvch)]

adin, it looks like you didn't attach the files while using the latest mainline kernel (which is now 4.7), as the article advises.

[adin (adin-rivera)]

I installed http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7/ generic amd64

However, there is no /sys/power/pm_trace. Do I need to do something else? From the article, it seems that the kernel should have that already.

Any advice on how to turn it on? or install it? My google-fu didn't return any pointers on how to achieve it.

Updated to Ubuntu 16.10, and the problem persists.

[Derrick (gallifrey2017)]

Finally!!! After 2 plus years of having this issue with no solutions, this worked!!!! Thank you so very much! I have not been able to enjoy running Linux on this expensive Alienware laptop since I bought it. I am curious why this is still an issue.. this has been an issue since at least Ubuntu 16.04.. still an issue in 18.04. In any case, I can confirm this script fixed my issue!! Many thanks!

[penalvch (penalvch)]

adin:

1) To keep this relevant to upstream, one will want to continue to test the latest mainline release (now 4.18-rc3) as it is released. Could you please advise?

2) Could you please advise if https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1607571/comments/25 provides a WORKAROUND?
