Don't list 160MHz channel width availability in Luci if the hardware doesn't support it #24

Not sure whether this should become a bug against Luci, but the Wi-Fi config allows a user to select 160MHz on a WRT1900AC, even though the hardware itself doesn't support it. Is this something that the driver/package advertises to the interface? It seems to correctly report its capabilities in iw:

Driver does not report capability of 160 MHz or 80+80 MHz.

@yuhhaurlin I realised this, my question is why does the Luci interface think that it does?

yuhhaurlin commented 9 years ago

I have no idea about that.

jguerin commented 9 years ago

@kaloz any idea...?

It's a luci bug https://forum.openwrt.org/viewtopic.php?pid=275615#p275615
