Re: Wifi drivers for RTL8191SE

I am logging in via GUI, more specifically Gnome.

I was just using the network manager that appears up by the clock and sound icons. When I right click on that and select 'edit connections' it takes me to the screen with wired, wireless, and VPN connection information. I then manually added the driver, but after that, no different functionality is available. I can take some screenshots if you want.


brad@moon:~$ modprobe r8192se_pci
FATAL: Error inserting r8192se_pci (/lib/modules/2.6.32-131.17.1.el6.x86_64/weak-updates/r8192se/r8192se_pci.ko): Operation not permitted
brad@moon:~$ sudo !!
sudo modprobe r8192se_pci
[sudo] password for brad:
brad@moon:~$ sudo modprobe r8192se_pci
brad@moon:~$ lsmod | grep r8192
r8192se_pci 509459 0
brad@moon:~$

Would it help to run the 'getInfo.sh' script? Or are the commands you had me run plenty enough info?

I am sorry, but I did not realize that I needed to run that command ( sudo modprobe r8192se_pci ) to enable the driver properly. What is the recommended way for this to automatically be done upon booting up? Since it requires root, wasnt sure exactly which file to add it to. (bashrc is the preferred file for non root commands correct?)

After running that I am able to get my wifi working properly! Thanks a lot.

Although I do still have one problem.... I can connect to my neighbor's unsecured wifi network no problem (I used it as a test), but am unable to connect my secured (WPA2) network. Additionally when I login to my router and look at the logs, I see no activity when trying to connect. Is it possible that the driver does not support WPA2 protocol or perhaps misses certain functionality?

If that is the case, it is not a huge deal, as I prefer to use wired/eth0 anyway, but nonetheless would like to understand why I can not connect to my wifi network, especially if its WPA2 related since that would limit me when I am in public areas with similar networks.


Thanks!

Did you reboot after installing the driver? It should not be necessary to manually modprobe. If it doesn't work after a reboot then it may be necessary to add an entry to /etc/modprobe.conf.

At least some results from a google on [url=http://www.google.com/search?q=r8192se_pci+wpa2&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a]r8192se_pci wpa2[/url] indicate success with WPA but not WPA2.

Yes I did reboot. I guess I need to add an entry in modprobe then. Would I add the command to that file (minus sudo) that I posted before?

Upon looking I see that I dont even have a modprobe.conf file in /etc/. I do however have a /etc/modprobe.d/

brad@moon:/etc/modprobe.d$ ls
anaconda.conf dist-alsa.conf libcxgb3.conf openfwwf.conf
blacklist.conf dist.conf libmlx4.conf rds.conf
blacklist-visor.conf dist-oss.conf ndiswrapper.conf
brad@moon:/etc/modprobe.d$

Actually I misspoke. For EL6 modprobe.conf has been depreciated in favor of /etc/modprobe.d/. Perhaps someone with that hardware can tell you the correct entry for a file in that directory. I would guess it should be of the form "alias ".

To [i]automagically[/i] load the module at system boot, one could create a file [b]/etc/sysconfig/modules/wifi.modules[/b] (owner & group [b]root[/b], mode [b]755[/b]) with the following contents --

[code]
[b]#!/bin/sh

modprobe r8192se_pci &>/dev/null[/b]
[/code]

Cool thanks, I have added that. Do you think that WPA2 functionality is something that will come over time and be picked up via 'sudo yum update' or is that something that I would need to update to 6.1 or 6.2 in the future for??

Also, could you please point me to the proper documentation that explains the config files in detail (like the one you just pointed me to) Clearly my understanding of linux config files is not up to par. I am much more familiar with FreeBSD and its approach. I am mainly concerned about which files do which and the various reasons you may want to modify each of them.

Thank you in advance.

Well as the driver source was provided directly by [b]Realtek[/b], I guess it depends upon whether they update the tarball and, thus, the [b]ELRepo Project[/b] update the [url=http://elrepo.org/tiki/kmod-r8192se]kmod-r8192se[/url] package [i]before[/i] [url=http://wiki.centos.org/FAQ/General?highlight=%28TUV%29#head-d29a2b7e61ffc544973098f9dd49fe4663efba50]TUV[/url] incorporate the driver module as part of the distributed kernel . . .

The best, published, reference material for anything EL6 related [i]has[/i] to be the Upstream documentation for [url=http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/index.html]RHEL 6[/url].

The other place to look is under the [b]/usr/share/doc/[/b] directory of your system.

Please let us know if you now consider that this thread's issue is resolved. If so, we (the moderators) can then mark it appropriately.

Thanks a lot. Yes I do believe it can be successfully closed.

Cheers!
