hostapd - slow [solved]

Hi all,

I am only getting about 20Mbps with hostapd on a Cisco AM10.  If I enabled 8011.n, I still only get about that speed, but only if wme_enabled=0.

interface=wlan0
driver=nl80211

# logging
logger_syslog=1
logger_syslog_level=3
logger_stdout=-1
logger_stdout_level=2

# Dump file for state information (on SIGUSR1)
#dump_file=/tmp/hostapd.dump
ctrl_interface=/var/run/hostapd
ctrl_interface_group=wheel

own_ip_addr=192.168.6.1

ssid=wireless
country_code=US
ieee80211d=1
hw_mode=g

# moved from channel 3 to 6 as most APs are on channel 1
channel=6

max_num_sta=16

rts_threshold=2347
fragm_threshold=2346
preamble=1

auth_algs=3
ignore_broadcast_ssid=0

# Disabled as 802.11n appears to slow wireless speeds down more ...
## 802.11n
ieee80211n=1
wmm_enabled=1
wme_enabled=0
##ht_capab=[HT40-][SHORT-GI-20][SHORT-GI-40]
##ht_capab=[HT40+][SHORT-GI-40][DSSS_CCK-40]
#
## settings for Cisco AM10
ht_capab=[TX-STBC][RX-STBC12][SMPS-STATIC][SHORT-GI-20][SHORT-GI-40][HT20][HT40]

If wme_enabled=1, then my 802.11n connection becomes very sporadic and I am lucky to get 5kbps.

iwconfig

wlan0     IEEE 802.11abgn  ESSID:"wireless"  
          Mode:Managed  Frequency:2.437 GHz  Access Point: 00:25:9C:FE:3F:09   
          Bit Rate=1 Mb/s   Tx-Power=14 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality=52/70  Signal level=-58 dBm  
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:242   Missed beacon:0

Any ideas what else to try?

Walter

Re: hostapd - slow [solved]

Hi all,

I figured this out in another post ... The solution was to not use Cisco AM10 and use TP-Link W722N.  I get much better throughput with it.
