wifi-stuff Posted April 15, 2014 Share Posted April 15, 2014 I'm not sure if I'm missing something or if this is a change from 1.3.0. If I tcpdump on wlan1, everything seems fine. Here are a couple lines (tcpdump -nn -i wlan1): 23:40:57.953918 285009224us tsft 24.0 Mb/s 2412 MHz 11g -62dB signal antenna 1 Request-To-Send TA:00:25:9c:c4:17:0c23:40:57.981066 285035543us tsft 1.0 Mb/s 2412 MHz 11g -64dB signal antenna 1 Beacon (SSIDHERE) [1.0* 2.0* 5.5* 11.0* 6.0 9.0 12.0 18.0 Mbit] ESS CH: 1, PRIVACY23:40:58.002669 285057975us tsft 12.0 Mb/s 2412 MHz 11g -64dB signal antenna 1 Clear-To-Send RA:f8:1e:df:d8:e6:f0 But if I tcpdump on wlan0, I get nothing for the rate and frequency information, and there's some clearly placeholder data here (tcpdump -nn -i wlan0): 23:41:49.638470 1358326477292044288us tsft 0.0 Mb/s 0 MHz Turbo -123dB signal [bit 29] Request-To-Send TA:bc:85:56:8e:48:b723:41:49.638490 1358327280450928640us tsft 0.0 Mb/s 0 MHz Turbo -123dB signal [bit 29] Clear-To-Send RA:bc:85:56:8e:48:b723:41:49.639045 1358327984825565184us tsft 0.0 Mb/s 0 MHz Turbo -123dB signal [bit 29] CF +QoS Data IV:14bec Pad 0 KeyID 0 It appears to be reading actual packets, but most of the 802_11_RADIO headers are bogus. airodump seems to be having trouble decoding that information as well, and is showing PWR and rate both as 0 for all BSSIDs. Using wlan1 with airodump shows correct signal and rate readings. Is this maybe a result of the driver upgrade? This worked fine in the previous version, or perhaps I forgot to twiddle some setting after I upgraded? I made sure hostapd isn't running, and I made sure the interface is up and tuned to a channel. tcpdump seems to think things are fine: root@Pineapple:~# tcpdump -L -i wlan0Data link types for wlan0 (use option -y to set): IEEE802_11_RADIO (802.11 plus radiotap header)root@Pineapple:~# tcpdump -L -i wlan1Data link types for wlan1 (use option -y to set): IEEE802_11_RADIO (802.11 plus radiotap header) 1.3.0 seems great otherwise so far! Thanks for the frequent updates! Quote Link to comment Share on other sites More sharing options...
