WiFi Not Working on Udoo Quad

Postby LDighera » Wed Jan 29, 2014 9:48 pm

Hello,

After installing Arch Linux ARM on my new Udoo Quad computer, I find that WiFi is not operable. Below is the Linux release information:
$this->bbcode_second_pass_quote('', '/')root (mxc1) # uname -a
Linux Udoo 3.0.35-8-ARCH #1 SMP PREEMPT Tue Jan 21 17:32:55 MST 2014 armv7l GNU/Linux


1. I don't find /dev/wlan*.

Here is the output from iwconfig wlan0:
$this->bbcode_second_pass_quote('', ' ') wlan0 IEEE 802.11bgn ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=0 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:on


And here is the output from ifconfig wlan0:
$this->bbcode_second_pass_quote('', '
') wlan0: flags=4098<BROADCAST,MULTICAST> mtu 1500
ether 7c:dd:90:3a:47:21 txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

So, obviously wlan0 exists.

2. Udoo documentation fails to mention what wireless hardware is on the Udoo board, but here's a clue as to what driver might be required.

Here is what lsusb shows:
$this->bbcode_second_pass_quote('', '/')root (mxc1) # lsusb

I do find:
$this->bbcode_second_pass_quote('', '

/usr/lib/firmware/rt3290.bin

But I'm not knowledgeable enough to know how to test either of those firmware packages/drivers to see if they might enable wireless support, and presumably the appropriate one would be configured in the Arch Linux ARM distribution.

Systemctl -a shows this:

All else, including Ethernet connection, appears to work as expected. Wireless works as expected under Ubuntu, so the hardware appears to be functional.

I find Arch Linux runs circles around Ubuntu with Xfce4 installed. In all, Arch a dream to use on the Udoo board.

Any clues as to how to enable WiFi functionality very much appreciated.

Thank you very much for the prompt and informative reply. Although I thought I had read that page long ago, it appears to have been significantly updated, and will keep me busy for some time.

However, I was expecting Arch Linux ARM wireless networking to be functional by default in the distribution, as it is in the Ubuntu distro.

I've attempted: 'modprobe rt2500usb' with the result:
$this->bbcode_second_pass_quote('', 'm')odprobe: ERROR: missing parameters. See -h.

This error message implies that a '-h' option will shed some light on the cause of the error, however 'modprobe -h' yields instead: $this->bbcode_second_pass_quote('', 'm')odprobe: ERROR: missing parameters. See -h.

And 'man modprobe' fails to contain a '-h' option, so I've been using '-v', which suppresses the error messages, but fails to load the rt2500usb module as verified with lsmod.

At least I'm learning a lot about the system mechanics.

Many thanks for the help.

Best regards,
Larry

Just assume module is builtin to kernel and doesn't show in lsmod, and try wifi-menu

Many thanks for your assistance.

I've done a lot of testing and reading on the link your provided and the links in the pages. I've found that invoking wpa_supplicant with the '-d' debug option to be very informative.

Here's a copy of my wpa_supplicant .conf file with obfuscated ASCII text 'secret_pass_key' and wpa_passphrase generated 'hex_pass_key':

$this->bbcode_second_pass_code('', '/root (mxc1) # cat /etc/wpa_supplicant/wpa_*conf
##### wpa_supplicant configuration file: LGD Mon Feb 10 13:18:19 PST 2014

# psk=hex_pass_key
priority=2
}


network={
ssid="NETGEAR32"
proto=WPA WPA2
key_mgmt=WPA-PSK
pairwise=CCMP
group=CCMP
#psk="secret_pass_key"

}

group=CCMP TKIP WEP104 WEP40
#psk="secret_pass_key"
psk=hex_pass_key
eap=TTLS PEAP TLS
}
')
This wpa_supplicant.conf file works on the Raspberry Pi. My wireless routers do not broadcast SSID.

Here is the state of wlan0 before invoking wpa_supplicant:
$this->bbcode_second_pass_code('', '/root (mxc1) # ip link show wlan0
3: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DORMANT group default qlen 1000
link/ether 7c:dd:90:3a:47:21 brd ff:ff:ff:ff:ff:ff
')

And here is the output from wpa_supplicant with the -d option:
$this->bbcode_second_pass_code('', '/root (5) # wpa_supplicant -B -c/etc/wpa_supplicant/wpa_supplicant.conf -iwlan0 -d

')
This appears to suggest that wpa_supplicant isn't using the passkey in its .conf file for some reason.

Once wpa_supplicant is running in daemon mode, invoking dhcpcd results in:
$this->bbcode_second_pass_code('', '/root (mxc1) # dhcpcd -d -A wlan0
dhcpcd[3645]: version 6.2.1 starting

dhcpcd[3645]: wlan0: waiting for carrier

')

Any clues appreciated.

Re: WiFi Not Working on Udoo Quad

Hi,

I have installed Archlinux on my Udoo Quad last week and the wifi is working without having to install any additional driver.

My router is using WPA2, I used the "spa_passphrase" command to generate the spa-supplicant conf file as described here: https://wiki.archlinux.org/index.php/WPA_Supplicant

This is what my spa-supplicant conf file looks like:
$this->bbcode_second_pass_code('', 'network={
ssid="myssid"
#psk="passkey"
psk=hexpasskey
}')

My Linux knowledge is very limited so let me know what commands I can run to help you.
