Internet connection dies while WIFI is still connected

[Johon Doee]

Hello.

Experiencing the following problem:

My connection to the internet dies randomly. Usually if I max out my connection speed but also when just plain serving. Happens not within a specific time frame.

While the wifi is still connected I cannot ping/connect to internet-servers anymore. Other devices connected to the router do not have this problem, so it seems to be an ubuntu-specific problem.

Configuration:
Ubuntu Zesty 64bit
Linux ubuntu-201604 4.10.0-21-generic
Card-2: Intel Wireless 8260 driver: iwlwifi, IF: wlp1s0
Linux-firmware 1.164.1.

Cannot remember if the problem occured with Ubuntu 16.10...

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 v4.12 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.

Tried it with kernel 4.12-rc7 and iwlwifi-8000C-31.ucode. This combination seems to stop the problems.
