Bug Description

This problem affects me on 13.04.
uname: Linux HTPC2 3.8.0-25-generic #37-Ubuntu SMP Thu Jun 6 20:47:07 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

Stable connection with good ping times, but throughput is measured in 10-20 kB/s.
Other linux machines on the same access point (NETGEAR WNDR3700v2) get 0.5 to 1 mB/s.

Additionally I noticed that attempting a data transfer over wifi on the effected machine has a detrimental effect on ping times for other machines on the same access point.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.10 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'.

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.
