Just for you (and others) reference, just because you're overriding the regulatory domain with a specific value doesn't mean the NIC has all the calibration data you need for operation on those channels. For example, just because you can configure a NIC to be in the japan country code, doesn't instantly give you access to the two 4.9ghz channels. :-) There's more involved then just overriding the regulatory domain. Hence, if it's an AR5416 or later, we can easily inspect the EEPROM calibration/channel edge values and see what the NIC is configured for. It's possible your NIC has channel edges which exclude > channel 11. At which point you won't be able to use those frequencies without (further) breaking all kinds of potential legal issues. Thanks, Adrian
