-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi! I'm trying to use HT40 channels on a Rt3050 SoC. I already fixed some stuff in the rt2x00 driver to set the RF in the exact same way as the rt2860v2 driver does. However, hostapd somehow still doesn't setup HT40 properly, though the debug output of hostapd says: HT40: control channel: 11 secondary channel: 7 Completing interface initialization Mode: IEEE 802.11g Channel: 11 Frequency: 2462 MHz nl80211: Set freq 2462 (ht_enabled=1 sec_channel_offset=-1)
Still HT40- is not configured properly: root@OpenWrt:/sys/kernel/debug/ieee80211/phy0# cat channel_type no ht TCP transfer rates are then much lower than in HT20 mode (around 600kbit/s instead of somewhere around 25MBit/s), supposingly because hostapd announces HT40- capability but doesn't operate the WiFi hardware in that mode. When I -- just after starting hostapd -- manually set the channel to HT40- by root@OpenWrt:/sys/kernel/debug/ieee80211/phy0# iw phy phy0 set channel 11 HT40- root@OpenWrt:/sys/kernel/debug/ieee80211/phy0# cat channel_type ht40- This kinda fixes it a bit and I can at least reach the same bandwidth as in HT20, but that seems to be related to the way the rt2x00 tells mac80211 about the supported transfer rate (should just be doubled, from what i read in the code, but haven't fully figured it out yet). Any ideas?
