I have debug USE flag disabled, I recompiled hostapd with that flag and now I can see log like your. You are right it's BSSs. Is there option to do not scan for overlapping BSSs? I know that it'll break some standards but that other networks are very week. I can't see them from my laptop. 2011/4/14 Christian Lamparter <chunkeey@xxxxxxxxxxxxxx>: > On Thursday 14 April 2011 21:36:05 Damian Lesiuk wrote: >> I don't have any more log. >> I dumped it by hostapd -dd /config/file &> log_file > > sure, this is what it looks like, your output is clearly "mangled". > > --- cut --- > # hostapd -dd /etc/hostapd/hostapd.conf.2ghz > Configuration file: /etc/hostapd/hostapd.conf.2ghz > ctrl_interface_group=0 > nl80211: Add own interface ifindex 7 > nl80211: New interface mon.wlanap created: ifindex=9 > nl80211: Add own interface ifindex 9 > BSS count 1, BSSID mask 00:00:00:00:00:00 (0 bits) > nl80211: Added 802.11b mode based on 802.11g information > Allowed channel: mode=1 chan=1 freq=2412 MHz max_tx_power=20 dBm > Allowed channel: mode=1 chan=2 freq=2417 MHz max_tx_power=20 dBm > Allowed channel: mode=1 chan=3 freq=2422 MHz max_tx_power=20 dBm > Allowed channel: mode=1 chan=4 freq=2427 MHz max_tx_power=20 dBm > Allowed channel: mode=1 chan=5 freq=2432 MHz max_tx_power=20 dBm > Allowed channel: mode=1 chan=6 freq=2437 MHz max_tx_power=20 dBm > Allowed channel: mode=1 chan=7 freq=2442 MHz max_tx_power=20 dBm > Allowed channel: mode=1 chan=8 freq=2447 MHz max_tx_power=20 dBm > Allowed channel: mode=1 chan=9 freq=2452 MHz max_tx_power=20 dBm > Allowed channel: mode=1 chan=10 freq=2457 MHz max_tx_power=20 dBm > Allowed channel: mode=1 chan=11 freq=2462 MHz max_tx_power=20 dBm > Allowed channel: mode=0 chan=1 freq=2412 MHz max_tx_power=20 dBm > Allowed channel: mode=0 chan=2 freq=2417 MHz max_tx_power=20 dBm > Allowed channel: mode=0 chan=3 freq=2422 MHz max_tx_power=20 dBm > Allowed channel: mode=0 chan=4 freq=2427 MHz max_tx_power=20 dBm > Allowed channel: mode=0 chan=5 freq=2432 MHz max_tx_power=20 dBm > Allowed channel: mode=0 chan=6 freq=2437 MHz max_tx_power=20 dBm > Allowed channel: mode=0 chan=7 freq=2442 MHz max_tx_power=20 dBm > Allowed channel: mode=0 chan=8 freq=2447 MHz max_tx_power=20 dBm > Allowed channel: mode=0 chan=9 freq=2452 MHz max_tx_power=20 dBm > Allowed channel: mode=0 chan=10 freq=2457 MHz max_tx_power=20 dBm > Allowed channel: mode=0 chan=11 freq=2462 MHz max_tx_power=20 dBm > RATE[0] rate=10 flags=0x1 > RATE[1] rate=20 flags=0x1 > RATE[2] rate=55 flags=0x1 > RATE[3] rate=110 flags=0x1 > RATE[4] rate=60 flags=0x0 > RATE[5] rate=90 flags=0x0 > RATE[6] rate=120 flags=0x0 > RATE[7] rate=180 flags=0x0 > RATE[8] rate=240 flags=0x0 > RATE[9] rate=360 flags=0x0 > RATE[10] rate=480 flags=0x0 > RATE[11] rate=540 flags=0x0 > Scan for neighboring BSSes prior to enabling 40 MHz channel > Scan requested (ret=0) - scan timeout 10 seconds > Interface initialization will be completed in a callback > nl80211: Event message available > nl80211: Scan trigger > RTM_NEWLINK: operstate=0 ifi_flags=0x1002 () > RTM_NEWLINK, IFLA_IFNAME: Interface 'mon.wlanap' added > Unknown event 5 > RTM_NEWLINK: operstate=0 ifi_flags=0x11043 ([UP][RUNNING][LOWER_UP]) > RTM_NEWLINK, IFLA_IFNAME: Interface 'mon.wlanap' added > Unknown event 5 > RTM_NEWLINK: operstate=0 ifi_flags=0x11043 ([UP][RUNNING][LOWER_UP]) > RTM_NEWLINK, IFLA_IFNAME: Interface 'wlanap' added > Unknown event 5 > nl80211: Event message available > nl80211: New scan results available > Received scan results (2 BSSes) > 40 MHz affected channel range: [2427,2477] MHz > Neighboring BSS: d8:5d:4c:c0:f8:e3 freq=2412 pri=1 sec=5 > 40 MHz pri/sec mismatch with BSS d8:5d:4c:c0:f8:e3 <2412,2432> (chan=1+) vs. <2462,2442> <==== > 20/40 MHz operation not permitted on channel pri=11 sec=7 based on overlapping BSSes <========= > Completing interface initialization > > --- cut --- > > Regards, > Â Â Â ÂChr > -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
