Bug Description

The new 3.13 kernel that came with kubuntu 14.04 creates some kind of issue with my internet connection. I get severe lag and stalled connections. I mostly noticed playing online games but also see package d/l progress pause/freeze during apt upgrades and sometimes my browser will not connect. The same day I upgraded there were no issues at all, now they are there. I found out it must be the kernel as i am currently using 3.11.0-19 and the issues have vanished.

Please let me know what other info to provide.

I thought I might also add that I had found another with this issue on AskUbuntu, http://askubuntu.com/questions/451724/wireless-connection-slow-inconsistent-after-fresh-install-ubuntu-14-04-realtek

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.15 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'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

I think that fixes it, I ran another ping test and saw nothing higher than 2ms save one random 20ms over a few hundred pings.

Thanks for the fix :)

rob loranger, the next step is to fully reverse commit bisect in order to identify the fix commit. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F ?

I have installed 3.15.0-031500rc7-generic following the instructions above. Leaving a ping running for 300 pings suggests that it does not fix the problem: 6% packet loss, which is how it was with 3.14.?? on a good day and while most pings are things like 2 or 3 ms, there are periodic occurrences of over 2s even 4s: very much the same pattern as another person reported earlier.

I am using an HP Pavilion laptop with Network controller: Realtek Semiconductor Co., Ltd. RTL8188EE Wireless Network Adapter (rev 01).

I first installed Kubuntu on this laptop in January (I think) using Kubuntu 13.10. That worked flawlessly (the first time I have ever had a Kubuntu/Ubuntu/Suse install go so smoothly!) The upgrade to Kubuntu 14.04 is when I started to notice wifi problems.

Sorry - of course I meant 3.13 not 3.14 when describing a good day.

Steve King (steveoldmanse-launchpad) wrote :

The recent upgrade to 3.13.0-27-generic seems to have fixed this problem completely. No packet loss, no pings taking longer than a couple of hundred ms and most in the 2-4ms range. It replaced 3.13.0-24-generic which did have the problem.
