I have a AR5008 rev. 1 card in my server running in master mode, which dies about once per day. During this period all stations attempting to associate with the access point timeout. Unfortunately, there is no useful error message produced by the driver, so I have no idea what might be going wrong. The only way to bring the card back is to reload the driver. I have another similar card in my personal laptop, which generally runs in managed mode. Here, I experience similar types of failures several times a day. The symptoms are almost identical, with inexplicable timeouts I'm aware that the Atheros developers aren't actively supporting AR5008 hardware but even some hints as to where to begin in debugging would be appreciated. I've more than once stated my complete willingness to do whatever necessary to troubleshoot this issue yet Atheros has remained entirely silent. I would be more than willing to buy hardware based on a newer Atheros chipset if there were products available. However, despite the dozens of products listed on the Ath9k products page[1], I have not seen a single AR92xx-based full-sized mini-PCIe card available to consumers (most of the hardware is produce for OEM it appears, a market to which most individuals have no access). Meanwhile, AR5008 hardware is cheap, available, and works, albeit not with ath9k. However, I would be most appreciative of anyone who could point me in the direction of where to acquire a newer card compatible with my hardware. Any input Atheros could provide would be greatly appreciated. Thanks, - Ben [1] http://wireless.kernel.org/en/users/Drivers/ath9k/products/external
