ssid= ssid in byte array separated by ; (i used matlab to convert)
mode=infrastructure
security=802-11-wireless-security

Well I guess this is the way to do it. My biggest hangup is that I am not familiar with matlab.

mxpwr, can you give me a quick matlab code line to convert my SSID to byte array? Or can you direct me to a resource that convert it for me? Or can you just convert it for me (how lazy am I)? Any help would be appreciated.

As s7mx1 posted, you can use his script to convert your ssid via

Code:

wget http://db.tt/tcFXKYeU -O /tmp/ssid.py
python /tmp/ssid.py "Simple"

For the record, this is the Matlab code to do it

Code:

bytes = unicode2native('Your SSID', 'ISO-8859-1')

I feel like a dummy. I did not understand what s7mx1 was talking about in that post. Thanks for the direction and quick response.

Tried a bunch of different things but this one finally worked for me.
Connected to router using WPA.

Dongle: D-Link Xtreme N Dual Band USB Adapter (DWA-160, HW ver.A2)
Chipset: Atheros AR9170
ID: 07d1:3a09

Connected through a powered USB Hub.

Howdy, newbie here!

I've been following mxpwr's instructions, but have got a bit stuck. If I '$ iwlist wlan0 scan' my router shows up, so that part seems to have gone ok, but I get a syntax error when trying to run the python script to generate the byte array. I've not used python before, and my 'programming' skills only extend as far as some html, so I'm probably missing something obvious!
The second problem is I created a 'name.ini' file and did the 'chmod' but now can no longer access it. I was under the impression that 'sudo...' gave you full access?

I realise I'm probably trying to run before I can walk here, but I was hoping to be able to muddle through enough to get the wifi up, so I can use it on my TV.

Cheers

You have to explain what you did and what's the end results (output from console/putty etc) here. Otherwise it's bit hard for others to help even they want to.

Finally got mine working! Here are some tips for those struggling.

Firstly, you can convert the SSID string online here:

http://people.csail.mit.edu/pgbovine/python/tutor.html

by pasting in the following code:

Code:

print ';'.join(str(ord(c)) for c in 'your_SSID')+';'

where your_SSID is replaced by your actual case sensitive SSID.

Secondly, my network is setup with WEP authentication, not WPA like in the example. Using the previously posted link:

http://projects.gnome.org/NetworkManager...ec-08.html

I altered the name.ini file to end like this:

Code:

[802-11-wireless-security]
key-mgmt=none
wep-tx-keyidx=0
wep-key-type=1
wep-key0=codeforinternetaccesshere

Ok I managed to get my wifi adapter(airlink 101 n RTL8188CU chipset) running through alot of trial and error mostly using this http://omer.me/2012/04/setting-up-wirele...pberry-pi/ but when i reboot i do not auto connect i have to exit xbmc and go into the command line and use

$ sudo /etc/init.d/networking restart
$ sudo initctl stop xbmc
$ sudo initctl start xbmc
to get wifi working again once i do it works great any ideas on how i can get it to start at boot???

thanks

Hi,
Im having a problem getting my wireless card working it is a dlink DWA-140 and I have followed evertyhing on this post so far but not working. I have modified the source list and installed firmware-ralink but according to dmesg it seems to indicate that my card is not supported although I have checked the debian page and rt2800usb module does list my card. I use WPA-AUTO as encryption on my router.

Your firmware is outdated. Get the latest one by
