Subject: NETDEV-BCM43XX BUG - Failure to associate AP with latest devscape
git pull..
Kernel = 2.6.19 SMP
bcmwl5 firmware = 4.10.40.0
Devscape bcm43xx_d80211 driver = Latest git pull
Wireless card = Broadcom Corporation Dell Wireless 1390 WLAN Mini-PCI
Card (rev 01) (PCI-E)
I seem to be having a problem associating with my AP--everything appears
fine and I can bring my wireless adapter up (the LED lights up
correctly), and I don't see complaints about firmware/IRQs in the dmesg
output. I am able to see operating APs with an "iwlist wlan0 scan", but
I am unable to connect to the AP, with or without WEP encryption enabled
(tried none, hex and ascii; nothing worked). This is with the latest
wireless-dev pull and a vanilla 2.6.19 kernel with "irqpoll" option
enabled, otherwise it misbehaves. I would be happy to give more
information if requested, or try different kernel/firmware options.
Here I have provided my dhclient connect attempt output with the
relevant tcpdump. Thank you greatly for your time.
