…which I think is correct. I’ve got a little USB wifi thingy that works fine on a Raspberry Pi and plugged it into the USB port on the back of the Conduit.
When I try to start up the wifi – ifup wlan0 – I get:
Successfully initialized wpa_supplicant
rfkill: Cannot open RFKILL control device
Could not read interface wlan0 flags: No such device
nl80211: Driver does not support authentication/association or connect commands
Could not read interface wlan0 flags: No such device
wlan0: Failed to initialize driver interface
ifconfig: SIOCGIFFLAGS: No such device
Obvious question first, do you have a compatible wifi adapter? (Which adapter are you using? Run lsusb and post the output please)
Keep in mind the RPi supports different (more) adapters.
I know of someone that did get wifi working on mLinux. As far as I understood he had to recompile the kernel to get the correct drivers included and working.
Here’s the output from lsusb @kersing. Is there a list of compatible adapters?

To check if your dongle is recognized, try loading the modules by hand: cd /lib/modules/3.12.27/kernel/drivers/net/wireless/rtlwifi/rtl8192c modprobe ./rtl8192c-common.ko cd ../rtl8192cu/ modprobe ./rtl8192cu.ko ifconfig -a
If you are lucky the modules load and recognize your hardware. If not you’re out of luck and the dongle is not supported.
People report mixed results with the driver on desktop Linux systems (low speed, dropped connections) so even if supported the results might not be what you expect.
You can check the output of lsmod to see if the modules were loaded and dmesg to check for any output generated by the modules.
I’m not aware of a list of compatible adapters. You could ask MultiTech on their forum…
Thanks very much Jac,
lsmod shows the modules loaded ok. Dmesg gave an interesting clue:

I raised a query on the Multitech forum yesterday, and will pursue a list of compatible adapters. We won’t be the only ones keen to connect over wifi. I’ll update here and the wiki when I get an answer.
I have a Wi-Fi adapter based on the rt2870 chip. I had a similar error, it detected the card but said it couldn’t find rt2870.bin. I downloaded this bin file from the kernel git repo, placed it in /lib/firmware/rt2870.bin and was able to connect using the same wpa_supplicant.conf and interfaces file. I suspect if you find the firmware for your device and place it in the correct location it should work.
Hello,
I just bought a Belkin wireless USB device, with a Realtek 8192cu chipset inside.
After plugged in the Multitech mlinux conduit, I see that modules are loaded well.
It fails when trying to load the firmware files.
Snipped from dmesg:

You’r welcome.
In addition, note that in the config file /etc/network/interfaces, the “allow-hotplug wlan0” trick does not make wlan0 interface up while booting without manual intervention.
I must use the normal way: “auto wlan0” to make it working
Hello Louis,
I’m not sure the auto wlan0 is really needed as stated in the /etc/network/interfaces :
#Wifi client
#NOTE: udev rules will bring up wlan0 automatically if a wifi device is detected
#and the wlan0 interface is defined, therefore an "auto wlan0" line is not needed.
#If "auto wlan0" is also specified, startup conflicts may result.
hi Louis,
I have also a belkin wifi dongle seen as a “rtl8192cu” in the dmesg logs; (under mLinux kernel version 3.12.27 too)
I tried to put the FW files as you suggested (in /lib/firmware/rtlwifi) but no success in showing up the WLAN0 :-/
Actually when the module is loaded ,dmesg gives a “Firmware is too big” error.
rtl8192cu: Loading firmware rtlwifi/rtl8192cufw.bin
rtlwifi:rtl_fw_cb():<0-0> Firmware is too big!
i guess the firmware file is not the good one, or is altered. Try to cross verify other sources of download for the fw file.
When you remove the firmware file, what is the full path written in the error in the log file ?
Hi Mark,
sorry for not having replied to your question.
I didn’t succeded in making running the wifi dongle so I kept the GW connected to Eth cable.
yet I’m still interested in getting hints and from your side ? how did you solve it ?
