Thanks James. I ran md5sum against both the two files you provided in the above link and those in /lib/modules/2.6.38.8/kernel/drivers/net/wireless/ and the checksums in each case were identical hence I am now confident that I haven't accidentally replaced those files with ones for 2.6.33.x kernel.

Determination has set in - I will get to the bottom of this (and learn a nice lot more about the innards of Linux in the process).

Using my JTAG I have carefully looked at the console output after a cold boot (shutdown, disconnected and reconnected power) and can see the following errors after the DHCP lookups for eth1:

I'm unsure why it is complaining about uap8xxx as I thought I had blacklisted that one. Looking in /etc/modprobe.d/blacklist.conf shows:

blacklist libertas
blacklist libertas_sdio
blacklist uap8xxx

And then I can see wpa_supplicant not playing ball, which just isn't sporting

Here's some relevant files - anything strike anyone as not right?

# cat /etc/network/interfaces

Code: [Select]

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

(obviously XXXX masks the SSID and key)

[leighbb]

Try as I can I can't get Wifi Client working... hmmm... Idea!

Have you tried using the libertas driver?  It works very well for me.

Assuming the kernel you are using has the libertas modules, create a file called /etc/modprobe.d/dreamplug-client.conf, with the following contents :-

Code: [Select]

blacklist uap8xxx
blacklist sd8xxx
softdep libertas_sdio pre: btmrvl_sdio

Also, make sure sd8688.bin and sd8688_helper.bin are in /lib/firmware/

Perhaps give it a try and see if you get any joy?

[cikub]

Thanks leighbb - from reading around the interwebs libertas may not be stable hence I want to avoid it if possible.

Plus I've come so far and am learning a heck of a lot about how this all hangs together that to be honest although it's *very* frustrating not yet having wifi up I'm gaining a lot from the experience!

[Confusticated]

Do you still have init_setup.sh hanging around, being called from /etc/rc.local at boot ?

[cikub]

I do, but it's mostly commented out now:

Code: [Select]


# cat /root/init_setup.sh
#!/bin/sh

# This is called from /etc/rc.local to perform the initial setup.

#SSID=dream-uAP-`ifconfig uap0 | awk -F ":" '/HWaddr/ {print $6$7}'`

#ifconfig uap0 192.168.1.1 up
#/usr/bin/uaputl sys_cfg_ssid $SSID
#/usr/bin/uaputl bss_start

service udhcpd start

# Start bluetooth
#hciconfig hci0 up
#hciconfig hci0 piscan
#/usr/bin/mute-agent &

#blinkled >> /dev/null
# Set leds

#echo 0 > `eval ls /sys/class/leds/guruplug\:red\:wmode/brightness`

Hi cikub,

Blacklist uap8xxx in  '/etc/modprobe.d/blacklist.conf'

reboot, then

insmod /lib/modules/2.6.38.8/kernel/drivers/net/wireless/mcypt.ko
insmod /lib/modules/2.6.38.8/kernel/drivers/net/wireless/sd8xxx.ko

then 'iwconfig' should give you

I too have no wlan.sh file so i tried running NewIT_James recipe and got the same output ... but what does this mean 
I have the Dreamplug multiboot using Debian Squeeze on both cards and want to turn off the AP and turn on the Wireless Client.
How do i progress ?

[NewITMalcolm]

How to convert the Debian Squeeze image from Access Point to a WPA client configuration.

Comment out this line from /etc/rc.local to prevent the startup script from running.

Code: [Select]

#/root/init_setup.sh
in /etc/modprobe.d/blacklist.conf Uncomment the line below to prevent the Access point module loading

Code: [Select]

blacklist uap8xxx
Run depmod to find and allow modprobe on sd8xxx.ko and mcypt.ko

Code: [Select]

depmod -a
in file /etc/modules add a new line to load sd8xxx.ko and mcypt.ko at boot

Code: [Select]

sd8xxx
add to /etc/network/interfaces

Code: [Select]

auto mlan0
iface mlan0 inet dhcp
    wpa-ssid YOUR-ESSID
    wpa-psk "your-password"
you will need wpa supplicant

Code: [Select]

apt-get update
apt-get install wpasupplicant

and you will probably want to remove udhcpd

Code: [Select]

update-rc.d udhcpd remove
Now a nice cold reboot

iwconfig should show the access point connected.

Hi James

Unfortunately I was unable to get this to work with either previous, or your most recent instructions. iwconfig shows:

Code: [Select]


lo        no wireless extensions.

eth0      no wireless extensions.

eth1      no wireless extensions.

pan0      no wireless extensions.

ifconfig also makes no mention of mlan0.

/etc/network/interfaces contains:

Code: [Select]

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp
        post-up iptables-restore < /etc/iptables.up.rules

auto eth1
iface eth1 inet dhcp

auto mlan0
iface mlan0 inet dhcp
 wpa-ssid ****
 wpa-psk "****"
(*** obviously replacing my actual values)

wpa supplicant is installed
/etc/rc.local has the init_setup.sh line commented out
udhcp command as provided was run
sp8xxx added
proper cold boot done (shutdown command followed by pulling power cable after the shutdown)
etc

I'm not sure if it is relevant but in Webmin for Network interfaces I can see:

eth0   Ethernet   From DHCP   From DHCP   Yes
eth1   Ethernet   From DHCP   From DHCP   Yes
lo   Loopback   No address configured   None   Yes
mlan0   Unknown   From DHCP   From DHCP   Yes

ie: mlan0 is Unknown - shouldn't it be Ethernet?

lsmod shows sd8xxx

Really stuck still

[NewITMalcolm]

The instructions were tested over a fresh Squeeze install. It may be easiest to start there and try again.

Thanks James

I read this post: http://www.newit.co.uk/forum/index.php/topic,2741.0.html - could the issues relating to firmware, kernel, etc there-in be affecting me? How can I tell?

[NewITMalcolm]

could the issues relating to firmware, kernel, etc there-in be affecting me? How can I tell?

If your serial no. starts DS2-1139 or above then yes. None of the plugs sold by us are affected.

hi James,
i am also having the same issues as cikub, when i  upgraded my brand new guru plug to squeeze it would not load the module for Wireless access point, at this point i am stuff on how to rebuild my guru plug, i was successfully able to connect jtag to the plug and so at least i can get in, the plug can connect to internet too, but just cannot let any device to connect to its wifi as the uap module is corrupt,
how do i rebuild my plug?
