problem with wifi connection

[ellecieffe]

Hello to all.
I have a A13 Olinuxino WiFi, booted with original 2GB Debian image and wired to the laptop trough USB-serial cable (with Putty on Ubuntu 12.04)

I'm trying to follow this guide to install Debian with graphical interface but I have some problems to establish a wifi connection.http://olimex.wordpress.com/2012/11/23/running-debian-with-xfce4-on-a13-olinuxino/

I have created a wireless network with ubuntu ...then on Putty I have typed:

Code Select Expand

ifconfig -a

indeed (like in the guide)

Code Select Expand

wlan1 Link encap:Ethernet HWaddr 48:02:2a:eb:21:1c
    inet addr:192.168.0.229 Bcast:192.168.0.255 Mask:255.255.255.0

    collisions:0 txqueuelen:1000
    RX bytes:31361 (30.6 KiB) TX bytes:1248 (1.2 KiB)

I have found

          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

However I tried to follow the guide and I've typed

Code Select Expand

vi /etc/network/interfaces

and then I edited like as follows

Code Select Expand

auto lo
iface lo inet loopback

auto eth1
iface eth1 inet dhcp

#auto wlan1
iface wlan1 inet dhcp

#auto wlan2
iface wlan2 inet dhcp

wpa-ssid **ssidname**
wpa-psk  **password**

#wpa-ssid OlimexAP
#wpa-psk Yourwifipassword
#    wpa-driver wext
#    wpa-ssid yourssidhere
#    wpa-key-mgmt WPA-PSK
#    wpa-psk encodedpskhere


I have rebooted and check again my connection with ifconfig -a but I have found again

Code Select Expand

wlan2     Link encap:Ethernet  HWaddr 48:02:2a:c5:f2:58

Where is the problem??
Thanks

[ellecieffe]

extra: at the beginning I typed

Code Select Expand

auto wlan2
iface wlan2 inet dhcp

wpa-ssid **ssidname**
wpa-psk  **password**
without #

So,when I rebooted it didn't found the connection,i think, and had entered  in a loop...  so I had to go edit again trough vi /etc/network/interfaces, modify that line (with the problem of check the line continuosly covered by the lines of boot) and reboot..wifi chip had become very hot !!

Also make sure you have the wpasupplicant package installed, which isn't by default. Or flash my image, and just modify the /etc/network/interfaces file with your information.

[ellecieffe]

hi jwischka, thanks for the reply!

I modified the code by removing the white space ( I will look the result at the next reboot). [ I used the more user friendly editor nano, instead of vi ]

The wpasupplicant package should to be installed on debian, on Ubuntu or on both ?

Unfortunately I haven't a microSD card reader,so I can't flash your image.
I'll do it just I can

[ellecieffe]

I have rebooted from the SD card but didn't work again,so I had to add # at the line one more time . However I've discovered that the same "loop" is generated if I type

Code Select Expand

ifup wlan2

wpasupplicant needs to be installed on the card that you're putting in the board. Try removing security on your router and seeing if you can connect then.

Do you actually have two wireless adapters installed? I would remove the second one, if not.

[ellecieffe]

I tried to follow this guide(in italian),http://guide.debianizzati.org/index.php/Configurazione_di_una_connessione_wireless   :

wlan2     No scan results

note   " Interface doesn't suppDriverStopped=1

btw at the point "Rete Wireless protetta con WPA" we have:

note that I have used wpa_passphrase and I've used WPA2-Personal (are key_mgmt,proto and pairwise ok?)
then Ihaven't used

pre-up wpa_supplicant -iwlan0 -c /etc/wpa_supplicant.conf -B

AARRGHHH 

help please

[ellecieffe]

Maybe I've figured out the  problem. I'm trying to use my acertravelmate 6592 as an access point but apparently the Intel Wireless WiFi Link 4965AGN is not suitable.
however,can I  still make an ad hoc network?

[iso9660]

Are you sure you have the required firmware wifi card file installed in /lib/firmware folder? Depending on the wifi card you use it might need a firmware.
http://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git;a=tree

[ellecieffe]

I've found this documentation http://wireless.kernel.org/en/users/Drivers/iwlegacy
.... so I can't use my acer in AP mode but only in IBSS (Ad-Hoc) mode .
Can you suggest me a Guide to do this,please ?

Hi guys...
Like you can see in the previous posts , I can't use my acer in AP mode but only in IBSS (Ad-Hoc) mode .

I've get a 8GB microSD and I've flashed the jwhischka image,R15....so, how I can configure the connection?
(I use USB to TTL Serial Cable to connect olinuxino to my PC,where I've installed PuTTY)

Thank to all

[JohnS]

If the info above is no good and google also isn't then probably buy an AP.

Have you edited /etc/network/interfaces in the image again? I assume you're trying to connect with the built-in wireless adapter on the A13-WIFI to an actual router? Or are you trying to connect it to your laptop?

If it's the second, I would echo what John said and just buy a real AP/router to use - they're cheap, and it will save you a lot of configuration headaches.

[ellecieffe]

I was trying to connect olinuxino with my laptop...ok, I will buy a router !!
thanks! good night all
