SqueezeBox 2 not able to join madwifi wlan
Last modified: 2008-12-18 11:38:39 UTC
I have a debian gw which also functions as WLAN AP. It's running an atheros chip based wifi card in master mode. The gw runs a kernel.org kernel version 2.6.11.5. The output from dmesg when the card is detected and modules is loaded is: ath_hal: module license 'Proprietary' taints kernel. ath_hal: 0.9.14.9 (AR5210, AR5211, AR5212, RF5111, RF5112, RF2413) wlan: 0.8.4.5 (EXPERIMENTAL) ath_rate_onoe: 1.0 ath_pci: 0.9.4.12 (EXPERIMENTAL) PCI: Found IRQ 9 for device 0000:02:0d.0 PCI: Sharing IRQ 9 with 0000:02:04.0 PCI: Sharing IRQ 9 with 0000:02:09.0 ath0: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps ath0: 11g rates: 1Mbps 2Mbps 5.5Mbps 11Mbps 6Mbps 9Mbps 12Mbps 18Mbps 24Mbps 36M bps 48Mbps 54Mbps ath0: mac 5.9 phy 4.3 radio 4.6 ath0: 802.11 address: 00:30:4f:39:30:31 ath0: Use hw queue 0 for WME_AC_BE traffic ath0: Use hw queue 1 for WME_AC_BK traffic ath0: Use hw queue 2 for WME_AC_VI traffic ath0: Use hw queue 3 for WME_AC_VO traffic ath0: Atheros 5212: mem=0xf2800000, irq=9 The network is setup like this (SID, and wep key changed - problem also persists with these settings):auto ath0 iface ath0 inet static wireless_essid homewlan wireless_mode Master wireless_channel 11 wireless_rate auto wireless_key 1122334455aabbddff11223344 #[1] address 10.10.11.1 netmask 255.255.255.0 wireless_txpower auto up /sbin/iwpriv ath0 mode 3 I am using this AP from a linux based pc running wlan in managed mode towards the AP. The laptop is also using an atheros based card (if you find that relevant) but have been working with other cards as well. When I enter the network config, type in the key - it still wont join. If I remove the key altogether it will join (at least it doesnt complain) but it wont obtain IP from DHCP server for the WLAN net.

Lars & Robin: Do either of you have the ability to run ethereal and sniff the wlan packets. We've only got one machine here that's capable of being an access point as you describe, but it's also our sniffer! A trace of the negotiation might make the solution obvious.
I have a laptop but it's 11b only, running XP. I have run the Auditor CD on it that has wireless sniffer on it. Will lock the AP in that mode, and have a go with this later. Unless you can recommend any windoze based tools?
Created attachment 650 [details] airodump capture - open This is a capture with encryption turned off on the access point. The SB2 was able to connect but not gain an address via DHCP.
Created attachment 651 [details] airodump capture - wep This is a capture with 64 bit WEP encryption turned on. The SB2 was not able to connect.
I have attached 2 files. One with WEP on, and the other from an open access point. What I find perculiar is that the open file shows no transmissions from the SB2. Perhaps it thinks it's sent something and connected when that really hasn't happened at all. At least on with WEP on I see some packets transmitted by the SB2, although of course this didn't even manage to access the network. I used airodump (from the remote-exploit live CD) running on a centrino laptop to get this. If you would like me to try something else, please advise.
Created attachment 653 [details] airodump capture - open - no filter SB2 MAC: 00:04:20:05:ac:a1 AP MAC: 00:11:95:c3:ef:db The access point was in open mode. This is unfiltered traffic from my building. Lots of Wlan action!
Can you please try firmware 41 available in the nightly releases. In this version most of the wireless connectivity problems have been fixed. If you still are having problems please reopen this bug. Thanks.
