Network adapter keeps on hanging up

[Gerardus]

Every hour or so, I'm unable to access the internet through this laptop. dmesg usually reports errors related to the network adapter, but not always. Disconnecting from the current Wifi network and connecting to another, usually works. Immediately connecting to the original network after that does not cause the problem to reoccur. At least, not for another hour or so.

I'm not sure how to better describe this bug.

The network also provides a nfs drive that is mounted on the laptop, if that is significant.

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 v4.10 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.

Hello Joseph,

That's not so easy to confirm (for upstream).

In the cause of confirming this bug - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1657907 - I've installed an upstream kernel and that bug was still present, and it also occurs every hour or so.

The difference between them, as far as I can tell, that that bug (1657907) logs a firmware crash, and this one (1668031) does not. I cannot, however, actively provocate the one or the other.

Are you able to see, if this bug is actually a different one?

My current workaround is, that I constantly have 2 terminal emulator windows open: one that is pinging google, so that I can see, when the connection is gone, and one in which I `sudo service network-manager restart`, when it is.

Let me know, if there is anything else I can do.

Gerardus,

Can you make a Zesty LiveUSB and test if this issue happens?

I just grabbed a Killer 1535 and seems like the issue does not happen on Zesty.

I'd like to make sure this issue is solved in 4.10, so I can bisect and backport needed patch.

Hey Kai-Heng,

Sorry for the late reply - we moved house and it was chaotic. Still is :)

To try to answer your question: I've got Zesty installed, and the issue is
still happening. I need to sudo service network-manager restart every so
often to get the data flowing.

Be sure to let me know if there's anything else I can help you with!

Many regards

Can you use latest mainline list and latest linux-firmware? If this issue still happens, please attach output of `journalctl -b`.
