Some WiFi devices can have extra EEPROM-based restrictions if they don't
implement some features.
I have a WiFi card that I can't use as access point on the 5 GHz band
because it doesn't implement radar detection, which is apparently
mandatory on this band to avoid causing interference.
Luckily I have another device based on a different chipset where it just
works.
