That said, what do you mean by "not working"? Details? What you've done/tried to make it work? Where you're getting messages? Run a lspci command and post the parts that reference the ethernet adapters. And is the device turned on? Most of those laptops are broadcom cards...do you have the broadcom firmware loaded? Any messages in dmesg about it? |

I don't see ifconfig recognizing a wireless device. What does 'lspci -v' output?
Edit Nevermind Edit #2: It would appear you have a BCM4313 wireless card. It would not appear however that it is using any drivers. What does 'modprobe b43' output? Try some of the instructions on this page: http://wireless.kernel.org/en/users/Drivers/b43 |
yes my wireless cards vendor is brodcom and from where I can download brodcom firmware
|
Quote:
http://wireless.kernel.org/en/users/Drivers/b43 You can do "yum install b43-firmware" and get the package. AGAIN...if you are NOT PAYING FOR RHEL, you should NOT USE IT. See previous comments about CentOS and server-distros on laptops, since you ignored them before. |
Also RHEL 6.4 is the current
the old 6.1 might not have any support for that card seeing as you are using the old 6.1 eather you ARE paying red hat an "arm and a leg" for support and the backports to 6.1 or this is an unsupported ,unregistered , and NOT paid for install if so you DO NOT install that driver !!! you must have a paid for support contract to install it ! or install the FREE rebuild CentOS 6.4 |
