Your AP did not provide 5 GHz frequencies in its country information element. Because of this the intersection between what CRDA has for GB and what your AP provides does not include any channels in 5 GHz. This has been fixed in wireless-testing though, if your AP country IE does not have information for a separate band we lave that band to trust CRDA information instead. This should have been propagated down to 29 already, maybe it'll be in rc5?
