It would, and thanks for the correction. This board's firmware carries Intel's wireless power methods and none of MediaTek's four. I put an MT7927 in it recently and the MediaTek ones did not appear, so they do not come with the card. > I don't think so (if this is the MTGS table above?), but I don't really > know how to parse the table contents. That is the right table, and nothing in it is padded.

Every line reads the same because the driver writes the same number into all of them: /* not used by fw */ rule->power_rule.max_antenna_gain = DBI_TO_MBI(6); rule->power_rule.max_eirp = DBM_TO_MBM(22); It is a placeholder rather than anything the card sent up, which is why the same twenty-two turns up under every country code and not only yours. So it is not evidence of what the radio will do in that band, in either direction. The card has a power table of its own, separate from this one, and debugfs shows it as txpower_sku. > The 5710-5735 range is also not covered, which results in 5 GHz channel > 144 being disabled (visible in `iw list`). That hole is in what the card replied with. The driver copies the ranges across untouched, so 144 goes with it. Devin
