Problem: wlan0 does not exist / WIFI Linksys USB adapter
#1
Hi

Would anyone have some info to get a USB WIFI network detected?  
Basically wlan0 is not in the network interface undifined for some reason , although the device is present. 
Also i made sure the Access Point is not left blank,, added the SSID info
Eth0 is working good, and connected
Im pretty sure it has to be a simple step missed , my first time using Moode.
I have put as much information sorry its a bit long thread.

cat  /etc/wpa_supplicant/wpa_supplicant.conf

syslog  Moode kernel detects the USB but with other manufacturer name instead of Linksys.. 
mtp.probe notes its not MTP device which is ok i guess.

Also noticed the file is missing the wlan0 server which is controlled by the moode application.. not sure if i should edit and add what PI recommends the default for auto detect etc.

Currently AP-Mode feature is only active if LAN is disconnected.

The situation has been described here.

@tracks 

This sounds similar to the problem reported by @agaufres

By default during its startup Raspbian now blocks the WiFi (via rfkill) if it finds the country code hasn't been set. The moOde configuration process undoes that and sets the country code to "US". However, @agaufres reported that his WiFi was blocked with a similar moOde report of the missing wlan interface. He is in Switzerland ("CH") and I infer you are in Sweden ("SE"). It isn't clear to me how the country code could be the root cause but I've repeated built and configured moOde in the US without incident.

What is the output you get when you run rfkill? If you see something like the following

Code:
pi@moode:~ $ sudo rfkill list
0: phy0: Wireless LAN
    Soft blocked: yes
    Hard blocked: no

then try unblocking it 

Code:
pi@moode:~ $ sudo rfkill unblock wlan


and check again for the wlan interface

Let us know if this works for you. If it does, then we need to revisit the way moOde initializes WiFi.

Regards,
Kent

Would anyone have some info to get a USB WIFI network detected?  
Basically wlan0 is not in the network interface undifined for some reason , although the device is present. 
Also i made sure the Access Point is not left blank,, added the SSID info
Eth0 is working good, and connected
Im pretty sure it has to be a simple step missed , my first time using Moode.
I have put as much information sorry its a bit long thread.

The message "wlan0 adapter does not exist" in moode log even though an adapter is physically present suggests a broken Build.

Which method did you select when you built moode 4.1?

Thanks for the suggestion Kent, but there is no rfkill process in my case,, i think its because the wlan0 is not present at all 
I think i need to try a new re-install with the USB WIFI attached, i answered Tim with that.

Hi,

Found problem,, documented it for the forum.

It turns out that the USB Wifi from Linksys does not have a linux driver , the way to found out is from the syslog as follows:

Jun  5 14:01:44 moode kernel: [    2.623406] usb 1-1.5: New USB device found, idVendor=13b1, idProduct=0042
Jun  5 14:01:44 moode kernel: [    2.638528] usb 1-1.5: New USB device strings: Mfr=1, Product=2, SerialNumber=3
Jun  5 14:01:44 moode kernel: [    2.653897] usb 1-1.5: Product: USBWLAN
Jun  5 14:01:44 moode kernel: [    2.665690] usb 1-1.5: Manufacturer: Qualcomm Atheros
Jun  5 14:01:44 moode kernel: [    2.678787] usb 1-1.5: SerialNumber: 12345678
Jun  5 14:01:44 moode kernel: [    3.212926] NET: Registered protocol family 10

Note that Qualcom Atheros is not the driver for Linksys and its bogus, 

The specs from USB LINKSYS has no drivers for Linux,, so i have to be carefull when buying those USB WIFI to double check compatibility..

Case close ordered a new one.. my favorit ASUS..

cheers

Hi Hubert,

I was going to post regarding possibly no driver support for the Linksys adapter but you've already determined that. One thing to be aware of is that even if manufacturer specifies "Linux driver available" in some few cases the driver is available but was never submitted to Linusx kernel. You would have to compile it into the kernel by hand :-0

Would you mind changing [PROBLEM] to [SOLVED] in you OP?

Thx,
-Tim
