Hi Steven, I'm CCing Linux-wireless as they might be able to help and I'm running out of ideas =) On Fri, Aug 1, 2014 at 1:21 AM, Steven <whereissteven@xxxxxxxxx> wrote: > Julian, > > > On 07/31/2014 02:28 PM, Julian Calaby wrote: >> Hi Steven, >> >> On Thu, Jul 31, 2014 at 8:47 PM, <whereissteven@xxxxxxxxx> wrote: >>> Hello Tim, >>> >>> Thanks for your advice and sorry for delay.

Actually I didn't manage to make it work again. This really looks like a hardware issue. Maybe your ath9k_htc device is particularly sensitive to power supply noise or something like that. Have you tried a different power supply or connecting it through a powered hub? I really wish I could help out more with this =) I'd be surprised if it's a software issue, but if you're compiling your own kernels, it might be worth checking out the Linux Backports project: https://backports.wiki.kernel.org/index.php/Main_Page Which is essentially the latest kernel's WiFi drivers and stuff repackaged so it can be compiled with older kernels.
