Question Redhat 6.4 - Help with Wireless Configuration please


Dear Experts,

I've installed Redhat 6.4 on an Acer laptop.

uname -a
Linux acer8372 2.6.39-400.17.1.el6uek.x86_64 #1 SMP Fri Feb 22 18:16:18 PST 2013 x86_64 x86_64 x86_64 GNU/Linux

cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.4 (Santiago)

And I'm having trouble getting the wireless networking to function.

---

I navigate:
Menu, System, Preferences, Network Connections

Create a new wireless connection. Then Edit.


I've been looking at this link, but it doesn't show the commands to find the SSID
https://access.redhat.com/documentat...onnection.html


So I tried using the SSID from my wireless router.
Is this correct?

----


SSID: Belkin_N_8236
Mode: Infrastructure
BSSID: blank
Device MAC address: 52:54:00:B7:??:??
- what I found with ifconfig and ip addr, for virbr0
Cloned MAC address: blank
MTU: Automatic

-----

But when I reboot, it's not up.

ethtool virbr0
Settings for virbr0:
Link detected: no

-----


Interestingly, I have not been able to find a wlan0 in all the analysis I've done.


cd /etc/sysconfig/network-scripts
cat ifcfg-Wireless_connection_1

ESSID="Belkin_N_8236"
MODE=Managed
TYPE=Wireless
BOOTPROTO=dhcp
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME=Belkin_N_8236

ONBOOT=yes
HWADDR=52:54:00:B7:??:??
PEERDNS=yes
PEERROUTES=yes

-----------

ethtool -P virbr0
Permanent address: 00:00:00:00:00:00


ethtool -i virbr0

What is the secret to get wireless to work on Redhat 6.4?


Thanks a lot!

It doesn't look to me like you have a working wireless card. Have you verified that it's working? Drivers loaded? Done a scan? What wireless chipset do you have?

virbr0 is an internal interface for virtual machines, it has nothing to do with your wireless.

contact redhat
you will likely need a driver from the RHN repo

plugin the laptop to a eth cable and do a system upgrade ASAP
the current in the 6 series is 6.6


also rhel and laptops do not mix well

not all the hardware is supported in a SERVER centric operating system

first if you are going to use 6
USE THE CURRENT version
RHEL 6.6

or better yet the CURRENT operating system
RHEL 7.0

but not all laptops and hardware is supported
is ALL of your hardware on the redhat hardware list ?

Thanks for responding.

The wireless card works perfectly fine on Windows, on the exact same laptop.
But so far, not on Linux.

When I installed, I tried to install every package possible.
Over 2500. Lots of mouse clicks.
I sure wish that Redhat and Oracle would make a button to "Install Everything" on the DVD.

lspci finds the network devices ok:


lspci
...
01:00.0 Network controller: Broadcom Corporation BCM43225 802.11b/g/n (rev 01)
03:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM57760 Gigabit Ethernet PCIe (rev 01)
...


According to Redhat, wireless worked in version 5:

Good tip on virbr0!

How I get wlan0?

What are all the drivers or packages are necessary for the wireless to work?


Thanks a lot!

You'll need to load the broadcom wireless drivers.

that is normally NOT a good idea
you will have a ton of code and background programs running for hardware and software you are NOT using

just because the hardware manufacture made a windows driver for some "propitiatory" hardware .Dose not mean they made a linux or apple driver .

this IS RHEL
so you DID buy the required support contract
login to the redhat site with the credentials you set yo when you bought the license
and search the knowledgebase for that Broadcom card
