In general, no. But depending on your setup and the card's EEPROM
(hardcoded world regulatory domain for instance), you may run into some
regulatory issues* and are required to patch the module, yeah.

However, if you live in the US and get a card with an US regdomain set
in its EEPROM, everything is fine. Unfortunately there is no way to
determine which regdomain is being used prior mounting it, so no
definite answer here.

Best regards,


Mihai

*) if I remember correctly, there are HT40 channels available on 2GHz in
(world_reg & us_reg), although not all US legitimate channels will work
with an unpatched version of ath9k if the card uses some world
regdomain, as regulatory restrictions are stacking. Ask Google for more,
I've had a thread on this mailing list regarding this as well.
