Roboard WIFI module problem with WPA2

[zaphod80013]

HELP!

I have a RB-110 using the VT6655 wifi module on a Debian 6.0.6 minimal LXDE install. I can get the card to the point where iwlist scan shows me the networks in my vicinity, so presumably the card and driver are functioning correctly.

When I try to connect to my home network (access point WZR-HP-G300NH running ddwrt v24SP2 with WPA2 Personal security [which I can't realistically disable]) I get the following error which repeats until the interface is shut down.

kernel: [ 1052.702751] SIOCSIWENCODEEXT:Enable WPA WEXT SUPPORT!!!!!
kernel: [ 1059.568373] set essid to myssid
kernel: [ 1059.569619] chester-abyDesireSSID=myssid

kernel: [ 1059.579619] chester-abyDesireSSID=myssid
kernel: [ 1062.802397] AP deauthed me, reason=2.


I've not been able to fine anything useful on Google, and at this point do not know if this is a driver, kernel or wpa_supplicant problem.

I also tried a Dlink DWA-131 usb dongle, compiling the latest drivers from Realtek (RTL8192SU chipset). the card only established a connection when I compiled the spa_supplicant version shipped with the driver (6.9) Debian installed 6.10.

from this I know the config is correct for my network but again the VT6655 failed with the same error. The kernel config file installed with the 2.6.34 vortex-sg kernel suggests all WEXT functions are compiled in. From this I suspect the problem is with the VT6655_stage driver but don't know what to try next.

Any help welcome.


thanks

Hi,

I am experiencing very similar problems trying to connect to my WPA2 secure Wireless network. Driver is successfully installed and "iwlist eth8 scan" shows the desired network (among others):

Code: Select all

I reviewed a lot of tutorials, blogs, forums, etc. which gave me information how to configure the /etc/network/interfaces file:

Code: Select all

auto lo
iface lo inet loopback

auto eth8
iface eth8 inet dhcp
wpa-driver wext
wpa-ssid GTBoekerFRA
wpa-ap-scan 1
wpa-proto RSN

wpa-group CCMP
wpa-key-mgmt WPA-PSK
wpa-psk f47029bf30710ed6007753e0122550ae71378f853433049e0f0ef1012adf75f8


The issue I am facing is that I cannot get a valid IP address from the DHCP:

Code: Select all

Anyone having a clue?

I made another test to verify that my RoBoard WLAN card works ok: I temporarily created an open WLAN Hotspot with my RAZRi mobile phone without security, i.e. no password needed. So I simplified the interfaces file to:

Code: Select all

auto lo
iface lo inet loopback

auto eth8
iface eth8 inet dhcp
wireless-essid RAZRi
wireless-channel 8
wireless-mode managed

..... and it works. I can ping (e.g. to google.com) and am connected to the internet.

So why does it not work with the WPA2 network at my home?

Marsman,

This is basically the same symptoms I was seeing, If I turn off WPA2 the Roboad connects fine and receives an address. You can verify your DHCP configuration by turning off WPA2 as a test, that will at least prove (or not) that the problem is in the wireless security rather than the DHCP configuration.

BTW: Unless you posted a dummy PSK here you may want to change your WPA2 key, admittedly low risk as somebody would need to know your location to use the key but It's probably not a good idea to post cipher keys or mac addresses.

If I have the time this weekend I was going to try to create a CrunchBang install for the Roboard (Debian 7 based i486 distro), If I have any better luck with the wireless I'll post here.
