[Bug 1591631] Re: Atheros AR928X Wireless Network Adapter has poor range


Jim Tarrant, in order to allow additional upstream developers to examine the issue, at your earliest convenience, could you please test the latest upstream kernel available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please keep in mind the following:
1) The one to test is at the very top line at the top of the page (not the daily folder).
2) The release names are irrelevant.
3) The folder time stamps aren't indicative of when the kernel actually was released upstream.
4) Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds .

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:

Where X, and Y are the first two numbers of the kernel version, and Z is
the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:

Please note, an error to install the kernel does not fit the criteria of

Also, you don't need to apport-collect further unless specifically
requested to do so.

Once testing of the latest upstream kernel is complete, please mark this
report Status Confirmed. Please let us know your results.

Thank you for your understanding.

Status in linux package in Ubuntu:

Bug description:
  My Atheros AR928X Wireless Network Adapter will only connect to my
  WiFi base station if it's very close to it.  When connected, if I move
  about 5 metres away, the connection drops.
