Comment 8 for bug 324213

I had the same issue on an Asus PC 1000HE with the same Atheros chip on 9.04, but the workaround gets the success rate of getting wireless up after suspend up to roughly 90% (estimated, not measured).

On 9.10 alpha 4, this is still an issue, though wireless comes up after suspend, but only works for a couple of seconds (say 10), before wireless network hangs for say 30 seconds, and then you get new 10 seconds of working wireless (and so on). This is progress from no networking, but still not usable.

The same workaround using /etc/pm/config.d/somefilename with SUSPEND_MODULES=ath9k solves this problem.
