/etc/config/wireless shows 11g and 11a (not 11ng 11na)

Description

Hi,
Not sure if this is a bug or expected but on /etc/config/wireless
on router WNDR3800, it shows 11g instead of 11ng, and 11a instead of 11na on 5ghz.

I used to use gargoyle which is based on AA, and it said 11ng, 11na.. and there was a choice to run 11g 11a.

In openwrt trunk, there's no choice in luci, just n+g and n+a, yet the wireless config file says as above???

Expected, config changed. 11g / 11a selects the band, htmode NOHT disables 11n, htmode HT20 / htmode HT40 enables 11n.

This keeps coming up. Maybe it should be made more clear, at least in Luci. Or add help text in Luci.

Same confusion here. Maybe some remark in Luci would be appropriate. Quite hard to look into the dev's brain, though my wife keeps telling me looking into other people's brain should be part of the standard configuration. Guess it's just me then... ;)

Is there any way to make it greenfield N-only and not G now?
Was there actually a working way before?

comment:5 follow-up: Changed 3 years ago by jow

As far as I know there is no greenfield support in ath9k.

Replying to jow:

As far as I know there is no greenfield support in ath9k.

Is that a driver thing or a hardware limitation?

This is a serious misnomer considering recent IEEE 802.11(#) specifications. The (#) part should not be used to specify a band. The (#) part specifies a protocol. Depending on country and drivers you can see exposure to bands other than 'traditional' 2.4GHZ and 5.2-break-5.8GHZ. You will see newer protocols specified on all bands. The current UCI/LUCI method is not forward portable to the future under our feet.

If you like to discuss this then discuss it upstream with the hostapd/mac80211 developers. Right now hostapd does use a or g to select the 5GHz or 2.4GHz bands, we merely extend that to the wireless configuration.
