Ethernet connection is extremely slow at times

[Matthew Nicolls]

I am running a Windows 10 with Ubuntu 14.04 dual boot. The internet on Windows works great and all sites load very quickly. On Ubuntu I am seeing spotty internet issues. At random times pages take ~30 seconds to load or I run a terminal command that downloads something and it hangs on a percent downloaded indefinitely. I can't seem to find a pattern to when it happens. Refreshing the web page or rerunning a stuck command usually will allow the file to download.

It happens in any application using the internet. I had Ubuntu 12 with a Windows 7 dual boot on the same machine previously without any problems.

I have tried disabling IPV6. Nothing changed.

I have been searching and I found results mentioning the Ethernet issues but they all talk about it not working at all. I do have an AS ROCK which makes me think it could be related (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1003297).

This has been happening since I upgraded many months ago and it is becoming unbearable.

Any help appreciated.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.5 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.

Also, do you recall the last kernel version that did not exhibit this bug?

[Matthew Nicolls (matt-m-nicolls)]

I am sorry I do not know any specifics on the version. I was somewhere on 12 and then I installed 14.04 and it has happened since it was installed.

And I am sorry. I have followed the tutorial to the best of my abilities but I do not see another boot option in Grub when I restart. I ran dpkg on the downloaded files, it ran without errors, and it appears that it is installed (I see them when running dpkg -l | grep "linux\-[a-z]*\-" ). I have done a few Google searches and I cannot find a solution.

What am I missing? How do I boot into the upstream kernel?

[Matthew Nicolls (matt-m-nicolls)]

I am also just having this issue when restarting since trying to install the upstream. Which is strange since it is from 2013. https://bugs.launchpad.net/ubuntu/+source/upstart/+bug/1174272

Maybe just a coincidence..
