I'm planning wifi card upgrade and I've decided to look for router targeted hardware because of better specs. I found MikroTik mPCI-E module that features Atheros AR9582. I also found that Linux driver ath9k does support this chipset. Does it mean this card should work under linux despite fact that It's meant for routers? Technically their hardware is as far as I know certified to work with OpenWRT. I'm not sure if OpenWRT uses the same drivers as ordinary linux distributions.
