I also see in dmesg:-

I see the same on all other boxes with the latest vanilla kernels but
they all get associated, not the beagleboard. The dongle is on the EHCI
port.
I have both connman and avahi-daemon disabled.

Got a little further by changes to wpa_supplicant.conf, looking for
further clues.

[Sid Boyce]

OK, "ifconfig wlan0 192.168.1.7", now I can ping other hosts and the router.

0.0.0.0 192.168.10.103 0.0.0.0 UG 0 0 0 eth0

It's a work around, just need to figure how to do it via the scripts
without having to use the wpa_supplicant command and manually configure
the interface.

[Deepak Narayan]

For me this worked without so much issues!. I am using a Dlink which
has the same Ra-link chipset .

my recipe is,

plugin wlan module . you get some usb messages

kill the wpa_supplicant process after booting up. make sure it gets
"killed" for sure. kill and bury.

# wpa_supplicant -B -Dwext -iwlan0 -c/etc/wpa_supplicant.conf

Then,

# iwconfig wlan0

should give the link status

# udhcpc -i wlan0

should bring the interface up using dhcp

hope this helps.

[Sid Boyce]

Thanks, I shall give it a try.
What I've done to get it running is to use a script in /etc/init.d that
isn't using udhcpc.
#!/bin/sh
wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant.conf &
sleep 5
ip route add 192.168.1.0/24 dev wlan0
ifconfig wlan0 192.168.1.7

route add -net 192.168.1.0/24 gw 192.168.1.1

I've also done one for eth0 as the normal scripts seem to ignore
/etc/network/interfaces settings.
Regards
Sid.

Anyone here made the exact guide on how to get the wifi working on beagleboard with Android on top of it.

Many of us are facing problems and it would be good if experience ppl can document a little bit about the process.
