| Sep 16, 2015 at 19:08 | comment | added | Ionică Bizău | @DavidLechner But is the configuration correct (see the question)? | |
| Sep 16, 2015 at 15:56 | comment | added | David Lechner | It means exactly what it says: there really is no "wlan0" device. There is no "wlan0" device because the driver is not loading. | |
| Sep 16, 2015 at 9:22 | comment | added | Ionică Bizău | @DavidLechner So, any idea why this error appears? | |

@DavidLechner Probably that helps too–I had to run something related for starting the sound. But I think the problem is in the configuration too (I appended it into the question). When I run sudo ifup wlan0 I get some errors: Cannot find device "wlan0" Bind socket to interface: No such device Failed to bring up wlan0. Any ideas?

rtl8192cu in the output of ls /lib/modules/3.18.13-v7+/kernel/drivers/net/wireless/ tells me that that out have the correct driver. Not sure why it is not loading though. Perhaps it is blacklisted? You could try running sudo modprobe 8192cu.

What is your kernel version (uname -r)? What is output of ls /lib/modules/<kernel-version>/kernel/drivers/net/wireless/?

| Aug 11, 2015 at 6:39 | comment | added | WineSoaked | The drivers on the CD may not compile to an ARM target architecture. You would have to transfer all of the files over to the Pi and then run the install script from there, unless the CD includes a cross-compiler. I haven't done it myself, so I don't have direct experience with this adapter. | |

@WineSoaked But... I have a CD with the drivers. And it contains an install script. I tried it and it compiles some C/C++ stuff and then fails: recipe for target 'modules' failed.

| Aug 11, 2015 at 6:37 | comment | added | WineSoaked | The somewhat longer option would be to locate a driver that will recognize that USB ID and make sure that it's available on the SD card. This is not a beginner-level task. | |
| Aug 11, 2015 at 6:36 | comment | added | WineSoaked | Yeah, it looks like the adapter is being enumerated, but no driver is being loaded for it. So... the short version of this is that you might need to get a different wifi adapter, one that is guaranteed to run on the version of Raspbian (or whatever OS you've chosen). | |
| Aug 11, 2015 at 6:30 | comment | added | Ionică Bizău | @WineSoaked Sure! I don't think would be a good idea to post it here in the question... :-) I connected an ethernet cable to make my life easier and I'm connected from my laptop via ssh to raspberry. | |

Can you provide any dmesg logs that describe what wifi adapter is detected? I'm wondering if the kernel is recognizing the USB ID and loading any modules.
