slackware14 and wifi r8712u module

xspirix · 10-02-2012, 06:16 PM

Hi there,
I have installed slackware14 and my wireless card stopped working. in 13.37 was fine. Probably it is a problem with the module in the kernel 3.2.29 version. Using Networkmanager or wicd I cannot get connection. That's weird because using i.e. kubuntu live 12.04 bearing 3.2.0 kernel the wireless works properly.
My device is:
Bus 001 Device 002: ID 0bda:8172 Realtek Semiconductor Corp. RTL8191SU 802.11n WLAN Adapter

I cannot really figure out where to check the problem. I have compiled also the kernel version 3.1.10 and 3.2.x but nothing changed.

any help??

thanks in advance

Have a look at the answer I gave here to a similar question.

PS. That driver works fine (and happy pollute your dmesg and syslog) until the kernel 3.6.0, where it don't like your credentials to connect at any network.

Thanks to everybody. I will try later on. The module is loaded at boot and networkmanager and/or wicd are able to see my wifi connection. In fact there is an attempt to connect to it but it fails. No error in messages or syslog neither in wpa_supplicant.log
I will try the patch. I confirm that in the kernel 3.2.0.x in kubuntu it works like a charm.
In order to apply the patch I just copy that code and in source code of the realtek driver type
patch -p1 < file ?? is this correct?

Yes. This is the right way.

BTW, you need this patch because this driver doesn't compile beyond of kernel 3.0.2 without it. Still, you will have reported some debug and an trace warning into dmesg and syslog. However, it works fine.

xspirix · 10-03-2012, 06:06 PM

Hi,
the patch and the installation of realtek driver were both fine. however still not working. first of all at the boot of 3.2.29 slackware load the r8712u driver properly. so I remove it with rmmod and I have loaded the new driver 8712u. but not success. networkmanager is able to connect but the connection is kept for a few seconds.
Now following this thread https://bugs.archlinux.org/task/27996 I have dowloaded the kernel 3.2.14 and 3.3.1 and I will try them.

just wondering whether do I need to downgrande the firmware too.

thanks in advance

xspirix · 10-04-2012, 02:17 AM

Nothing changed. neither 3.2.14 or 3.3.1 worked for my realtek. I am really wondering now if I need to downgrade the firmware to the old one (13.37 version)

H_TeXMeX_H · 10-04-2012, 04:50 AM

Why 3.3.1 ? That's not even stable. Try 3.4.12, that's the one I know works. The firmware should already be installed, so it should work. Make sure you have the configuration set up properly.

xspirix · 10-04-2012, 04:52 AM

that was from the archlinux mailing list. are you saying that in 3.4.12 the RTL8191SU works?

H_TeXMeX_H · 10-04-2012, 05:32 AM

I have used the 8712u module with 3.4.12 and it works.

xspirix · 10-04-2012, 05:53 AM

Ok. so you are talking about the realtek official driver with the 3.4.12 kernel. Fine I will try it. The driver that you have used are the same shown in the previous post? and have you used the same patch for it?

thanks a lot

H_TeXMeX_H · 10-04-2012, 05:59 AM

I have only used the one in the staging area of the kernel.

Code:

CONFIG_R8712U=m

If it still doesn't work, make sure you have the most recent firmware (should already be installed in 14.0).

xspirix · 10-04-2012, 06:16 AM

ah okay. So you are using the r8712u module. the 8712u module is from the realtek official driver.

thanks a lot. I will surely try it

xspirix · 10-05-2012, 03:33 PM

Hi guys, 3.4.12 worked like a charm!!! the connection went fine through networkmanager in kde. The only thing strange is that the google webpage and similar (gmail, etc ...) does not work!! other sites works perfectly. in the same time using another computer (windows and/or) the google webpage are not visualized too. as soon I close the connection on my slackware workstation everything is back fine on the other pc!! I tried several time and it seems that when my slackware workstation is connected the google webpage is stopped.... it is so weird isn't_????

any help???

thanks agagin

Which module worked? The native r8712u or the Realtek 8712u?
