Was the wireless interface working before, under the previous OS you had installed?  You can try creating a live usb to boot from with one of the following fedora spins. A liveusb is a way of booting into a OS without having to install so you can see what you think etc.Then boot from the live usb  to check if you see a wirelesss interface via ifconfig and/or if you see any wireless connections via network manager. That way we'll know at least if the wireless interface is still working.


Try what helikaon said first, just figured your wireless was working before on your previous os http://www.madjacksports.com/forum/images/smilies/facepalm.gif

Hi

Thanks for the help. Here is the output of the commands:

[root@LizardoUNACH Lizardo]# lspci | grep -i network
04:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188EE Wireless Network Adapter (rev 01)
[root@LizardoUNACH Lizardo]# iw list
[root@LizardoUNACH Lizardo]#

For the dmesg command the relevant lines, in my opinion, are:
rtl8188ee: Using firmware rtlwifi/rtl8188efw.bin
rtlwifi: Firmware rtlwifi/rtl8188efw.bin not available

[root@LizardoUNACH Lizardo]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
TYPE=Ethernet
UUID=4615132f-d0f8-481b-8342-5535f6fa5ce8
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=dhcp
HWADDR=00:25:AB:6A:94:B5
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME="System eth0"

However, I must confess I dont fully understand the meaning of the output of the commands.
By the way, the complete output of dmesg is around 1000 lines. If you think I should post it tell me.

Kind regards,

Lizardo

Ok,
firstly, you have only one network adapter on your PC - the wifi adapter, or at least the lspci command is not showing any other adapter.
secondly, the 'dmesg' command revealed where the problem is. You have to install rpm package containing the missing firmware for your wifi card.

I'll try to have a look if i can find the rpm later today, too busy in office atm :-)


cheers,

Seems like you need this package: rtlwifi-firmware
try:

CODE

yum install rtlwifi-firmware


According to that post the kernel-it doesn't contain the actual firmware, but strange cause burakkucat located the kernel module in the kernel-it and it was loaded.

Thanks inittux.
btw i think it is right, yeah, module is loaded, because the module is part of the new kernel installed, but firmware is part of rpm package.
So yeah, you can have module loaded, but without fw it doesnt' work..

cheers

Hi guys

With the command suggested by inittux I get:

Installed:
rtlwifi-firmware.noarch 0:20131223git-1.el6.elrepo
Complete!

So seems Im improving step by step rolleyes.gif . What else do you think I should do?

Kind regards,

Lizardo

When you click on NetworkManager now, do you see any wireless networks? If not show the output of what helikaon asked you to do before.

CODE

dmesg | grep rtlwifi

Good, if I do dmesg | grep rtlwifi I can read:

rtl8188ee: using firmware rtlwifi/rtl8188efw.bin
rtlwifi: wireless switch is on

However, if I go to system -> preferences -> network connections I can't see any wireless option.

So seems Im getting close...

good,

do you see output when used:
CODE

iw list


if you do, than it works and only the GUI tool you use is not registering it

Do you use NetworkManager to display network connections?

cheers

On your desktop somewhere in the top right or bottom right you should have a network icon(two computers icon thing). If you click on it, wireless networks should be displayed. Sounds like you are manually trying to add a wireless connections via the the network settings in menu. See link

Yours will be an icon of two computers, click on that and wireless connections in the area should show up.

Hi guys

Sorry for coming back to this point, but I have the following related problem.
When I do yum update I get the following:

Transaction Check Error:
file /lib/firmware/rtlwifi/rtl8192cfw.bin from install of kernel-firmware-2.6.32-642.el6.noarch conflicts with file from package rtlwifi-firmware-20131223git-1.el6.elrepo.noarch
file /lib/firmware/rtlwifi/rtl8192cfwU_B.bin from install of kernel-firmware-2.6.32-642.el6.noarch conflicts with file from package rtlwifi-firmware-20131223git-1.el6.elrepo.noarch
file /lib/firmware/rtlwifi/rtl8192defw.bin from install of kernel-firmware-2.6.32-642.el6.noarch conflicts with file from package rtlwifi-firmware-20131223git-1.el6.elrepo.noarch

I thought it was related to the elrepo repository, but after disabling it, the problem continues. I have the same problem in two different kernels: 3.10.101-1.el6.elrepo.x86_64 and 2.6.32-573.26.1.el6.x86_64

What do you think I should do?

Thanks again for your help!

There's seems to be a conflict between something in the sl repo and the elrepo repo.

Do

CODE

rpm -ql   kernel-firmware


and

CODE

rpm  -ql  rtlwifi-firmware


That way you can see what firmwares is listed in the packages and compare to what firmwares that could cause the conflict. Your system is just protecting it's base repo by giving you this error

Hi inittux

Yes, with the second command I can see a list of rtlwifi-firmwares, among them the problematic ones: rtl8192cfw.bin, rtl8192cfwU_B.bin and rtl8192defw.bin ; what should I do with them? Should I delete them to avoid the conflict?

Cheers,

Lizardo

remove rtlwifi-firmware, then do a yum update and reboot and see if your wireless still works. I remember burakkucat mentioning that in SL6.8 the wifi drivers were available. When you reboot boot into the default rhel kernel, 2.6 something.After you reboot check what version of SL you are running

cat /etc/redhat-release

And also what redhat kernel you are booted into.

If it says 6.8 check if you wireless still works.

Seems I cant remove the conflicting rtlwifi firmwares. Even if I do

[root@LizardoUNACH Lizardo]# rm /lib/firmware/rtlwifi/rtl8192cfw.bin /lib/firmware/rtlwifi/rtl8192cfwU_B.bin /lib/firmware/rtlwifi/rtl8192defw.bin

and i re-try the yum update, I still get the error message

Transaction Check Error:
file /lib/firmware/rtlwifi/rtl8192cfw.bin from install of kernel-firmware-2.6.32-642.el6.noarch conflicts with file from package rtlwifi-firmware-20131223git-1.el6.elrepo.noarch
file /lib/firmware/rtlwifi/rtl8192cfwU_B.bin from install of kernel-firmware-2.6.32-642.el6.noarch conflicts with file from package rtlwifi-firmware-20131223git-1.el6.elrepo.noarch

Im using SL 6.7 and the kernel is 3.10.101-1.el6.elrepo.x86_64 because it is the only kernel where the wireless works.

Did you try? And what happens when you do this?

CODE

yum remove rtlwifi-firmware


And then if the previous succeeded:

CODE

yum update


Then reboot and, selec the SL default kernel to boot in not elrepo kernel. Once booted check what version of SL you are now running

CODE

cat /etc/redhat-release


Then check if you're wireless still works if you are updated to 6.8.
