WIFI Dongle Edimax EW7811UN not working after last update

Sat Jun 25, 2016 11:34 am

Hi,

after I updated my pi with the latest raspian I can´t use my Edimax Wifi Dongle for creating an acesspoint.

Sirtting here now since three days and nights trying to get this little thing to work

I tryed now nearly every Driver file and hostapd-file for the edimax dongle I found in the web and every time it doesen´t work.
With an earlier raspain jessie Version and the special hostapd from Dave Conroy it works without any Problems. But when I try the 4.4.13-v7+ I got the problems.
I can create a local Network and I can see it with an other device but when I try to connect with the pis wlan then the device tells connecting....passphrase...getting ip-adress....and then connecting...passphrase...getting ip-adress....and so on (try to translate from german to english).
When using -dd hostapd.config I can see that the devices try to connect with the dongle but with no sucess.

Is it possible to put the edimax to the pi for wlan acess Point with the latest raspian and if so how??
Or must I build a edimax hostapd from source? If so how to do??
What is a suggestion for a small wifi Dongel working with the pi without any driver Problems?

Thanks and regards

Andreas

Hi,

the most useful (but not working) hostapd brings this when starting hostapd.config with the -dd option:

Hi Andy,

I have exactly the same problem with my AP. Could you resolve the problem already?

Taggin on to this is I did the stupid thing of updating a day before our rocket launch to get the new picamera and it took out the AP side of things.
Great fun having to dismantle everything between launches to get the SD card out to empty it. :x :lol:

That'll teach me :)

But would like to know a sulution.
I had it setup via http://raspberry-at-home.com/hotspot-wifi-access-point/ but removed the bridging if a WiFi could be created section to ethernet as it wasn't needed. I even used the ifup/ifdown part in the first comment.

Was working, now not and similar to aboves description of what happens.

Think I've found a fix for it.

Code: Select all

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install libnl-genl-3-dev libcurl4-openssl-dev 
git clone https://github.com/lostincynicism/hostapd-rtl8188.git
cd hostapd-rtl8188
cd hostapd
sudo make
sudo make install
cd ..
sudo mv hostapd /usr/sbin/hostapd.rtl8188
sudo mv /usr/sbin/hostapd /usr/sbin/hostapd.old
sudo ln -sf /usr/sbin/hostapd.rtl8188 /usr/sbin/hostapd
sudo chown root.root /usr/sbin/hostapd
sudo chmod 755 /usr/sbin/hostapd
Give that a try. It worked for me (along with http://elinux.org/RPI-Wireless-Hotspot and http://www.daveconroy.com/turn-your-ras ... s-chipset/ instructions)

Thank you.

Unfortunately, this is not working for me. Compiling and running the hostapd as you described, works for Jessi befor the upgrade (I did this to verify that the new hostapd is working for me at all).

The I did an apt-get upgrade and recompiles the hostapd again. But with the upgraded Jessie, even this hostapd does not work any more.

Any other ideas what the problem with the Jessie upgrade and the hostapd could be?

Dear Andreas,

Thank you for your post. Unfortunately I do not have a solution. But finding your post made me realize I wasn't the only one with this problem. I had my Pi running as an AP for about two weeks when "all of a sudden" it stopped working. Later I realized that I updated the system. Finding your post has made me stop tweaking and changing every little configuration item in "interfaces" and "hostapd.conf". Fortunately for me I have my Pi only acting as an AP and a simple samba server. I decided to re-install and reconfigure the system and not to do an "apt-get upgrade". I had to do an "apt-get update" though to get Samba to install. This took me about an hour. And indeed, the AP is running fine again. If I can be of any futher assistence, please let me know. For example, I can now see that (I a working condition) the bridge br0 shows both the eth0 and the wlan0 interface. Before the " downgrade" it would only show eth0. It seems that (part of) the problem is that wlan0 isn't added to the br0 bridge...

Regards,
Rolf

Code: Select all

[email protected]:/usr/bin# brctl show br0
bridge name	bridge id		STP enabled	interfaces
br0		8000.aca213665485	no		eth0
							                wlan0

Hi,

I am also stuck up since I did a rpi-update. Tried to compile hostapd from source with RTLxdrv patch as well, but no luck.

Anyone has any information?

Eshwar

I have the same problem. Using this wifi dongle for a long time, but after the last update it is not working anymore. Please note: When changing the hostapd.conf to make the access point open (without WPA2 or other encryption) it is still working. Turning on WPA2 creates the mentioned problem again.

I think the wifi-encryption is not all done by hostapd itself but relies on a kernel-functionality. Last update of raspbian brought a new kernel.

I just found this thread right now and I already created another thread about this problem (sorry!). Have a look there if you need more detailed informations about this problem: viewtopic.php?f=28&t=154347

At least I realise now, that I am not the only one with this problem. I really would be happy if somebody could find a solution, as I am really lost...

Best regards!

As far as we see in this thread, it seems like the problem is there since the new kernel. So it should be a good idea to ask the developers of raspbian for help. Thats why I posted a thread in the raspbian section of this forum (viewtopic.php?f=66&t=154413). Hope there will be a good discussion that leads to a solution of this issue.

Don't know which kernel you mean but 4.4 I'm sure it's been working fine.
The last updates that came down after which I noticed it was a bunch of firmwares for various things*. Which was a few weeks ago now.
I don't know where to look to see the order of updates to Raspian by time.



*I actually have a feeling these may have been a bunch of networking device firnware.

Andreas29 said, this problem occured after update to kernel 4.4.13-v7+. In my case it is also the same, after the update to kernel 4.4.13-v7+ the problems occurred.

You are right, it was not the only update. There was also firmware updated. But hostapd is still working very nice without encryption. Just if encryption like WPA2 is enabled, no client can connect anymore. Thats why I am not so sure if this could be caused by the updates of the firmware.

But anyway, I think the only solution is to get help or informations from the developers of rasbian. Lets hope they will reply!

I mentioned the firmware as that's all I remember, I don't remember anything kernel wise coming down.
I may be a new rtl8188 based firmware that came down with them? Who knows but at least all the posts are nicely linked :D

You can see this in /var/log/apt. Maybe you can check that?

No, there is no rtl8188 based firmware for access point (hostapd) delivered with raspbian, just the drivers for using this device as client (wpa_supplicant). The drivers for using the device as access point is compiled into your custom version of hostapd.

Will have a look, just need to find whichSD card I have it set on.
I'd have thought it would just use the dongle driver, guess not. Since you know how it all works I'll leave you to figure it out :D I'll drop to an insecure connection once I find the card as security doesn't matter here.

I have a working hostapd config that uses the Pi 3 internal wifi interface. I simply had to plug the USB key in and modify "interface=" in hostapd.conf to make the Edimax adapter work. WPA2, wifi-N speed. It all works with the standard hostapd package now.

That's great! epoch1970, I have tried and can confirm this!

The standard hostapd is working with driver=nl80211. No need for a custom compiled hostapd anymore.

Thank you very much!

@epoch1970

so reading through your solution, using a Raspberry Pi B+ ( New model ) and 2.

command

cat /etc/modprobe.d/8192cu.conf
Says 'No such files or directory'

You have to create this file (I did after I found my AP would go poof overnight, YMMV, maybe you don't need to create it)
What works for me is a file named /etc/mod probe.d/8192cu.conf that contains the following line:

Code: Select all

options 8192cu rtw_power_mgnt=0 rtw_enusbss=0 rtw_hwpwrp_detect=0 rtw_ips_mode=1
(cat is a command to list a text file. When I quote a bit of system config or message, I tend to include the command that produced it; this way others can run the same command and compare.)

Hi,

bad News. When using the newest Image (not updating a previous System) I don´t get this litle piece of junk to work as an acess point.
When I used an updated older System it worked. But when using the original Image, downloaded from the pi´s web side I didn´t get it to work.

He´s not able to connect to a client.

Now I bought a dongle with an other chipset (ralink 5370) and hope this works.

Regards

Andreas

Hi,

Interesting to hear now there some success with stock hostapd.
I'm trying to have same success with rtl8188eu which happens to depends on same nl80211 driver.

I see references about kernel versions, but can one of you mention which hostapd version you are actually running?
It seems nl80211 relevant changes happened in v2.5 and 2.6, so I'm curious to hear which version is successful.

Thanks!

The one in the raspbian (stable) repository, currently "hostapd 1:2.3-1+deb8u4". Basically, download raspbian and it will work.
rtl8188eu might be another kind of beast?
