> Recently, it has been reported that D-Link DWA-582 cards, which use an

> The problem was solved once I learned that the internal country code was
> resulting in a regulatory set with only 2.4 GHz channels. With the RTL8821AE
> chips available to me, the country code was such that both 2.4 and 5 GHz
> channels are allowed. The fix is to allow both bands even when the EEPROM
> is incorrectly encoded.
