> Same issue as you described. Your messages offer more information than I
got. I also find that the outage event and client bridge death can be
found in hostapd debug logs. That is, when outage event happens all wds-
stations lost connections with wds-ap. Forget to mention I have about 6-10
stations and all connected to one wds-ap. Do you think by any chance this
is a hostapd related issue? If you have found the origin of the issue or
get a solution please send me an email. Thanks a lot.
Are you sure it's the same issue? Do you even have the same hardware?
I had thought about coming back and closing this. It is my opinion now
that what I am seeing is either a hardware failure or some kind of
fault/bug in the software for this wireless hardware.
The problem has nothing to do with bridging. I just started seeing it more
often on a bridged host, but I am able to reproduce the problem on non-
bridged hosts as well. It took a lot of troubleshooting to figure that out
though.
I started using a USB attached Realtek adapter and the problems on that
interface went away, so it's something specific to the built-in Atheros
hardware. It's either bad hardware or some bugs in software specific to
the hardware.
I had given up on this issue anyway. The hardware is old and I plan to
replace it.
