That device is supported by rtl8xxxu.

Hi Xose,

I'm not sure, I have the latest version of Ubuntu on my laptop and I
had to use the DKMS -2 deb file to get it working as no driver claimed
it.

After Googeling (especially for the 0bda:818b USB device and vendor
ID), it seemed the driver supported most of Realtek's WiFi devices but
mine wasn't listed.

>From memory, I used this page mainly when I was first checking:

I didn't see any people in forums mentioning how they managed to get
this standard driver working, they all seemed to either have no luck
because code didn't compile, or link to source code that did compile.

If that mainline driver does work, then I assume there could be some
USB vendor and device IDs that it doesn't cover.

Here's the link for where I bought it:

Patches to add rtl8192eu support was pulled into wireless-drivers-next
recently and scheduled for the 4.7 kernel. It is not in Linus' tree
yet. You should be able to try it out by either building Kalle's
wireless-drivers-next or my rtl8xxxu-devel branch.

The Realtek 8192EU driver you referenced is not scheduled to get pulled
into the upstream Linux kernel.

Re: Realtek USB WiFi rtl8192eu

[Fisher Grubb]

Hi Jes,

Thanks for the info.

Ok, so I assume I just Google how to bring/compile a newer
"unreleased" driver into a previous kernel version.

Do I just need my current kernel's headers and typical GCC build toolchain?

This is for Debian 7.9 on the ARM based BeagleBone Black board (Texas
Instruments Sitara AM3358 CPU), which I uses kernel v3.8.13-bone79.

I'm asking in case there's a big difference between kernel 3 to 4 for
this type of driver to be compiled.

I'm pretty sure certain kernel customisations were added by Robert
Nelson for this board (I think he is quite involved with
porting/fixing stuff for this board and the raspberry pi) , so I don't
know how easy it would be for me to use a version 4 kernel.

Thanks,

Fisher

Bringing back the driver into an older kernel is an open question. No
idea if that will work or not. Also note that ARM support is very
lightly tested and I do not believe anyone tested rtl8192eu support with
ARM.

Note that the driver currently does not support MESH and AP mode.

Hi all,

The version of driver which I think came on my CD is
rtl8192EU_linux_v4.2.2_7585.20130524

Here's a page which may have the original code:
https://sites.google.com/site/easylinuxtipsproject/reserve-7

Here's another Github repository that claims to be more regularly
updated and links to a D-Link version of the driver (using same
Realtek chip):

Realtek USB WiFi rtl8192eu

[Fisher Grubb]

Hi all,

I don't know if this stick's driver is in the process of being
incorporated into the Kernel drivers, I havn't seen so yet.

I've put the full lsusb -v at end of email as its a lot of stuff.

Please let me know if any other info is needed about it, I'm not a
programmer but I have reasonable intermediate Linux knowledge.

I have been commonly using this stick with my ARM based BeagleBone
Black board, others commonly use it with their ARM based Raspberry
PIs.

lsusb gives:

Bus 002 Device 003: ID 0bda:818b Realtek Semiconductor Corp.

I'm not sure when Realtek released this version of their WiFi chip,
Linux source code comes on the driver CD, but usually doesn't compile
as it seems to be for older systems.

I've found 2 DKMS deb files that work, as well as somone's modified
source code on Github.

Its still buggy and I don't think gives signal strength etc.

Here's a link to modified source code on Github that compiled for me
and worked when the DKMS debs didn't:

https://github.com/bhuvanchandra/rtl8192eu

Here's a link to the 2 deb DKMS packages, usually one compiles and
works (the one with -2 at end of file name), it didn't compile on
Debian 7.9 on my BeagleBone Black board the other night,   the other
one did, though I couldn't get it to work with the wex driver using
wpa_supplicant, complained of ioctl "operation not permitted" etc.

http://laptopke.be/files/Debian/
http://users.telenet.be/x86_64/Debian/

Hopefully this can be properly incorporated and standardised with most
commonly used driver/extensions etc as I understand that Realtek
drivers don't conform properly with the Kernel wireless extensions.
