_Really, there is no other good solution anyway, and using an adapter
let's you exchange cards/chips even more easily or maybe share them also
between Laptops and such, that's actually pretty great.

If you don't want to go for the Ubiquiti model, I can recommend the
SparkLan WPEA-127N card (AR9380 chip). Using it for about a month,
getting decent speeds and no problems/lockups/??? yet (but this
regulatory stuff, oh well. ;))

Uhm, that's totally harmless. I'd say local radio stations or phone
cells do affect your health a dozen of times more, but anyway, that's
plain overanxiousness. WLAN won't give you cancer or brain damage
(disregarding the already mentioned regulatory stuff, which may inflict
severe brain damage.)

I guess all ath9k supported cards are capable of reducing the transmit
power, so yeah.

Best regards,


Mihai
