Bug #278

Default to HT40+ mode on 5ghz

Added by Dave Täht on Sep 25, 2011. Updated on Apr 21, 2012.
Closed Normal Dave Täht

Description

5ghz is much cleaner spectrum than 2.4ghz, so defaulting to ht40+ makes sense.

History

This will be fixed in the first rc7 smoketest
Updated by Stephen Walker on Sep 30, 2011.
Broken on the latest rc7 smoketest:
rootOpenWrt:~# wifi up
[…]
Configuration file: /var/run/hostapd-phy1.conf
HT40 channel pair (40, 1) not allowed
Interface initialization failed
[…]@

Cerofiles’ mac80211.sh needs to use channel 36 or 44 when using HT40+ per the freq table at http://hostap.epitest.fi/gitweb/gitweb.cgi?p=hostap.git;a=blob;f=hostapd/hostapd.conf;hb=HEAD#l381.

OpenWrt’s mac80211.sh is currently using channel 36.

I will use 36 in rc7-smoketest4 (this is still broken in smoketest3). Thx for the heads up. I would prefer frankly to not use 36 or 44, but something higher, as to not conflict with other APs by default.

The much higher 149 or 157 are available.

has HT40+ enabled on channel 36. It’s also from openwrt head.

Seems to work well as a default
