Removing the 80Mhz check entirely is not the right way to go IMO. The check is there because there are countries where VHT rates are not allowed, even on 20MHz channels. We use the fact these countries have no 80MHz-allowed ranges as a crude regulatory hint to disable VHT entirely. I'm not sure about the regulatory landscape in these countries regarding VHT in 2.4GHz, but please don't break compliance for the 5Ghz use-case. Arik
