The problem isn't there for the bits that Ivo sent, as the rt2500 devices don't support the a band.
For rt2500pci and rt2500usb there are chipsets which support 5GHz (they are rare, but they do exist),
comments for the Ralink drivers indicate they simply didn't add the regulatory domain definitions yet.
Based on the documentation from the EEPROM for all devices I read that its recommended
that the EEPROM *not be relied on for the regulatory domain*, instead it recommends the
windows registry be used.
Based on tests for the devices with only one band, do are you seeing an actual regulatory
domain in the EEPROM?
To deal with the issue of having two separate EEPROM values for a regulatory domain
and since the documentation indicates to not rely on it I would advise to allow users
to be compliant by selecting the country they are in. wpa_supplicant has support for
selecting country now, and so does iw. Eventually I see Network Manager letting users
select the country. But you guys are the maintainers and developers so you will know
better.
My tests indicate that there are devices out there that have this
information set in the EEPROM. Based on tests with my own patch, and my
own devices, I have been able to determine the following:
1. rt2400pci --> don't know, don't own a rt2400pci device.
2. rt2500pci --> don't know, don't own a rt2500pci device anymore.
3. rt2500usb --> my e-tech device (not sure which type; the device
doesn't say it) has an actual domain set for the bg band.
4. rt61pci --> my Sitecom WL151 device does not contain actual domain
information.
5. rt73usb --> my Sitecom WL113-002 device does contain actual domain
information, and the codes for the bg band and a band are the same.
6. rt2800pci --> my Sitecom WL182 device does contain actual domain
information, and the codes for the bg band and a band are the same.
7. rt2800usb --> my Sitecom WL181 device does contain actual domain
information, and the codes for the bg band and a band are the same.
So, there are devices out there that do contain "meaningful" regulatory
information.
Luis, the definitions for the a-band EEPROM codes only give the channel
numbers, it doesn't indicate a real "country". Is there any way we can
check whether these sets of channels are actually consistent with the
regulations of specific countries?
