Edimax EW-7811UTC Raspbian

[AussieSusan]

I just want to say a very big THANK YOU for the work you have done and especially for the install-wifi script.
I was having all sorts of problems and this installed the drivers so simply.

Hi
Thanks for all your efforts MrEngman

Just to clarify,
Does this mean the RTL8812AU chipset is now capable of monitor mode in the latest version of Rasbian?

What are you referring to? I have no idea if monitor mode works as I only use the drivers to connect my Pis to APs.

Many many thanks to MrEngman, with your script (install-wifi v5), 3 usb wifi 5GHz below work like a charm on RPI2/Volumio 4.4.9-v7+:

- Linksys WUSB6300 (RTL8812au)
- D-Link DWA-171 A1 (RTL8811au)
- Edimax EW-7811UTC (RTL8811au)

But on RPI2/RuneAudio 4.1.20-1-ARCH, after follow many help on the web, I do not know how to make it work.

Please help me install Linksys WUSB6300 on RuneAudio 4.1.20-1-ARCH. I am very grateful for your help!

Thank you again!

MrEngman,

Can you provide the source you are compiling for the 8812au driver or point us at the repo you are referencing? While I appreciate the binaries you provide, I like to tinker and experiment myself. Thanks!

I am currently using the driver source from here https://github.com/diederikdehaas/rtl8812AU.

Hello Mr Engman,

Any chance you can include the latest driver for the Edimax EW-7811UTC (RTL8811au) running on OSMC?

Post the output of command uname -a and I'll see what I can do.

Linux Pi 4.4.27-4-osmc #1 PREEMPT Tue Nov 22 02:25:13 UTC 2016 armv6l GNU/Linux

modinfo 8812au | grep v4
version: v4.2.2_7502.20130517

In Kodi, video playback stops after a minute or so, otherwise all other network traffic seems to work ok.

Your help in getting me to try the latest driver would be appreciated.

[Lotus77]

Hi MrEngMan,

I tried your precompiled 8812au-4.4.34-v7-930.tar.gz and I see no change in performance; I still get stalls in data traffic and video playback stops.

Edimax pointed me to this location for an open source driver: https://github.com/gnab/rtl8812au

During compilation I get this error message below, any ideas what is wrong?

Unfortunately wifi module manufacturers don't seem to care to much about supplying drivers for Linux. Looking at the source Edimax pointed you to it does appear to be largely pretty old which may be why you have the problem you have.

You could try here https://github.com/diederikdehaas/rtl8812AU. There are several different versions 4.3.8, 4.3.14, 4.3.20 and 4.3.22-beta.

No idea what the issue is then.

I have no problems compiling any of the diederikdehaas drivers.

One thing I found a bit odd. You say you tried the driver I compiled 8812au-4.4.34-v7-930.tar.gz which is for PI 2B, 3B but the info you posted about the compile error would seem to indicate you are compiling it for a Pi 1, or B+

make ARCH=arm CROSS_COMPILE= -C /usr/src/rbp1-headers-4.4.27-4-osmc M=/home/osmc/rtl8812au modules

Just a bit confusing.

[Lotus77]

Yes, I used 8812au-4.4.34-v7-930.tar.gz on a Gen 1 Model B and it worked apart from having the same kodi stalling symptoms I can't seem to shake off.

Wondering if you can kindly compile me one?

I find that rather hard to believe as it is compiled to work with a Pi 2B or 3B.

I'll have a look at compiling a driver but it's not as easy as compiling for Raspbian so may take some time.

[Lotus77]

I was able to compile https://github.com/diederikdehaas/rtl88 ... ver-4.3.20 using apt-get install linux-headers-4.4.0-1-rpi however the Kodi video playback stop still occurs after a few seconds in 5 GHz .ac mode. I've disabled background scans in connman.

Sorry I didn't get round to creating a compiled driver as I've gone down with a really bad cold and I'm in no state to do much at the moment.

There are a couple of other versions of the code available but whether either of those will fix your problem I don't know. I would expect not. Mind you what if it is an issue with Kodi rather than the wifi driver.

I did some tests using iperf and had my Pi running for more than 24hrs with no apparent problems. Bandwidth was around about 94-95 Mbits/sec, transferring approx. 40 GBytes/hr.



MrEngman

[Lotus77]

In 5 GHz .ac mode I get the same 80-100Mbps throughputs with iperf and samba file copies. It is a peculiar situation however with Kodi where the first 10-20MB come through fast and then traffic just stalls forcing the video to stop. This issue with Kodi does not happen when in 2.4 GHz mode.

Hi,

I have DietPi installed on a Raspberry Pi 3, which just automatically updated the kernel to:

root@DietPi-2:~# uname -a
Linux DietPi-2 4.4.44-v7+ #2 SMP Wed Jan 25 23:12:28 UTC 2017 armv7l GNU/Linux

Is there an updated driver I could use to get my dongle working again?

Cheers...

[SteveDee]

In 5 GHz .ac mode ...This issue with Kodi does not happen when in 2.4 GHz mode.

This looks very similar to a problem I have with BBC radio streams: viewtopic.php?f=28&t=149242&p=981452#p981452

I've just picked this problem up for a second look, as 2.4GHz is v.busy locally and interference is a problem, but I'm the only one using 5GHz.

The Edimax AC600 works on my Lubuntu laptop at 5GHz with the BBC streams. So its not the dongle or the driver when compiled for x64. Sorry, I have the same problem on my laptop with the gnab driver. When I tested it, it just happened to run for a couple of minutes so I thought it was working.

Please post back if you find a solution.

[tbqnzdypdrkw]

I got my EW-7811UTC finally run on 5GHz (!) with the help of https://layereight.de/raspberry-pi/2016 ... 812au.html (THANKS!). Only with this how-to I could see 5GHz WIFIs. Afterwards I had to switch my WLAN 5GHz router settings to channel "36, 40, 44, 48" instead of "automatic". Of course less channels, but a almost all neighbours jumping around at 2.4GHz channels

[tbqnzdypdrkw]

I can run EW-7811UTC now with 5GHz WIFI!
Thanks to this great how-to https://layereight.de/raspberry-pi/2016 ... 812au.html I could find 5Ghz WIFI around, but in beginning to mine..
I had to switch to WIFI Channels "36, 40, 44, 48" instead of "automatic" setting in my router.

[bluenote]

Is the RTL8811AU chipset a good choice if I want to make an access point out of a pi? The other use would be with libre elec just as a client. thanks
