Forwarded to linux-wireless@xxxxxxxxxxxxxxx because of "decrypt failed" messages. -------- Original Message -------- Subject: [AirForce One 54g] working Resent-Date: Sun, 16 Sep 2007 23:12:55 +0100 Resent-From: Gavin McCullagh <gmccullagh@xxxxxxxxx> Resent-To: bcm43xx-dev@xxxxxxxxxxxxxxxx Date: Sun, 16 Sep 2007 22:45:02 +0100 From: Gavin McCullagh <gmccullagh@xxxxxxxxx> Reply-To: Gavin McCullagh <gmccullagh@xxxxxxxxx> To: bcm43xx-dev@xxxxxxxxxxxxxxxx Hi, I have a linksys WPC54GS pcmcia wifi card. lspci details below. I tried it with the latest firmware and Ubuntu gutsy's 2.6.22-10-generic and 2.6.22-11-generic kernels. With the former, I got WPA working intermittently, but not stably (ie it'd die and need the driver reloading). With the latter, I could only get it working unencrypted (I didn't debug in detail, but it seemed like it didn't associate so presumaby the link never came up -- I can give logs and more detail if it's useful). I went onto the IRC channel and noted the suggestion that I try the wireless-dev tree (2.6.23-rc4). So I did and I'm glad to say successfully. I'm using it now and have been for the past 6-8 hours on and off without any reboot or problems. I guess it's possible it would also work with the current 2.6.23-rc6 development kernel. Perhaps I'll try and check that in due course. A couple of things worth mentioning. 1. I've been getting tonnes of syslog errors like this: Sep 16 21:46:59 tilly kernel: [ 5171.869169] CCMP: decrypt failed: STA=00:09:5b:d2:f0:2f Sep 16 21:46:59 tilly kernel: [ 5171.872336] CCMP: decrypt failed: STA=00:18:84:11:78:d6 Sep 16 21:47:05 tilly kernel: [ 5174.178449] printk: 122 messages suppressed. which all seem to correspond to packets tranferred between my AP and a second netgear laptop with an atheros chipset. So it's not a worry. ifconfig shows a collossal packet drop count, which seems to approximately equal the number of packets sent+rec'd by the other laptop so I guess it's the same error as above. Perhaps there's a good debug reason for these printk statements, but they have their cost on the machine. 2. The quoted signal strength is 50% even when I have the AP and card right next to each other. It doesn't bother me, but I wonder if it's correct or not. I wrote up a howto for Ubuntu here as I suspect others might be interested to try it out. https://help.ubuntu.com/community/WifiDocs/Device/Broadcom_BCM4318_%5bAirForce_One_54g%5d_%28Native_Driver%29#preview Gavin gavinmc@tilly:~$ lspci -v -s 02:00.0 02:00.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02) Subsystem: Linksys Unknown device 0049 Flags: bus master, fast devsel, latency 64, IRQ 10 Memory at 24000000 (32-bit, non-prefetchable) [size=8K] gavinmc@tilly:~$ lspci -vn -s 02:00.0 02:00.0 0280: 14e4:4318 (rev 02) Subsystem: 1737:0049 Flags: bus master, fast devsel, latency 64, IRQ 10 Memory at 24000000 (32-bit, non-prefetchable) [size=8K] _______________________________________________ Bcm43xx-dev mailing list Bcm43xx-dev@xxxxxxxxxxxxxxxx https://lists.berlios.de/mailman/listinfo/bcm43xx-dev - 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
