Hello again, I'm having problems having SL 6.4 recognize my built in wireless adapter.

The relevant output of lspci -nn is:

CODE
07:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. Device [10ec:8179] (rev 01)


So I looked for the Vendor:Device ID pairing of 10ec:8179 on ELRepo but didn't find it in the list. Drat!

Googling on the Net I found that this particular network adapter should be managed by this particular driver by Realtek, as it appears that the adapter contains the RTL8188EE chip.

So, after downloading the driver, the README tells me to run the /compat/script/compat-install.sh (as a quick use of uname -r tells me that my kernel is 2.6.32-358.el6.x86_64).

Unfortunately, the script fails. I uploaded the output on a txt file that you can download here:
https://app.box.com/s/0jex7tqotpep1qoq4g67
(It's very long, and I deemed it would have been infeasible to put it between CODE tags: I hope it's the right way to post long outputs)
Suggestions?

I see that the rtl8188ee driver is included in the upcoming EL7. But that will not be out for many (?) months. You can try filing a RFE with ELRepo. There is no guarantee that it will be provided though.

Performing the following on my laptop system --
CODE

[Duo2 ~]$ rpm -qa kernel\* | sort
kernel-2.6.32-431.el6.x86_64
kernel-firmware-2.6.32-431.el6.noarch
kernel-headers-2.6.32-431.el6.x86_64
kernel-lt-3.10.23-1.el6.elrepo.x86_64
kernel-ml-3.12.4-1.el6.elrepo.x86_64
[Duo2 ~]$ grep -i 10ec /lib/modules/*/modules.alias | grep 8179
/lib/modules/3.10.23-1.el6.elrepo.x86_64/modules.alias:alias pci:v000010ECd00008179sv*sd*bc*sc*i* rtl8188ee
/lib/modules/3.12.4-1.el6.elrepo.x86_64/modules.alias:alias pci:v000010ECd00008179sv*sd*bc*sc*i* rtl8188ee
[Duo2 ~]$

So I would suggest that you consider using the kernel-lt package set to obtain support for that wireless adapter. smile.gif

I am ashamed to admit that I don't know what a RFE is sad.gif

I installed the kernel-lt and tried to run the script again, to no avail, same error messages.
Are there other steps that have to be performed? Please forgive my ignorance, I'ma bit of a newcomer to Linux sad.gif

Okay, problem solved!

I downloaded a set of packages called "backports", specifically from this directory, and issued the following commands (found on an Ubuntu forum, but whatever):

CODE
make clean
make defconfig-rtlwifi
make
make install


After rebooting the wireless adapter was fully functional:

CODE
wlan1    Link encap:Ethernet  HWaddr 70:18:8B:4B:8B:0D
         inet addr:192.168.0.104  Bcast:192.168.0.255  Mask:255.255.255.0
         inet6 addr: fe80::7218:8bff:fe4b:8b0d/64 Scope:Link
         UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
         RX packets:10519 errors:0 dropped:0 overruns:0 frame:0
         TX packets:7627 errors:0 dropped:0 overruns:0 carrier:0
         collisions:0 txqueuelen:1000
         RX bytes:7556322 (7.2 MiB)  TX bytes:4260173 (4.0 MiB)


Thanks anyway guys!

You did not need to "run the script again" as the kernel-lt package contains the relevant driver!
