Hi,
I'm very new to Linux, I have installed CentOS 6 on my new laptop (Toshiba Portege R830-M14K) in dual boot with Windows 7, I want to use the CentOS for my daily work, so far, the OS was installed successfully, however, I don't know how to get the wireless works in order to connect to wireless networks.
I have added the SSID of my wireless in "Network Connections" & the encryption protocol/password, however, it did not work.
I need help to check whether the Wireless NIC driver is correctly installed and identified by the OS, and is there anything else to be checked or installed.
Thanks

If you're new to Linux and trying to get Wireless working, CentOS 6 might not be the best distro for you.

I'd suggest looking at Ubuntu 11.10 or Mint

The reason for this is three-fold:

1. Those operating systems are geared towards novice users
2. Lots of people use them, and have faced lots of problems. Lots of known solutions exist on Google.
3. Given the above, your wireless will probably work out of box anyway. But even if it doesn't, you'll have an easy time fixing it.

crunchbang is also lightweight distro that comes with wifi drivers.

I have found a driver in www.intellinuxwireless.org for my Intel wireless adapter driver, it is iwlwifi-6000g2b-ucode-18.168.6.1.gz , I have extracted it to come with tar file, I extracted it again and came a folder with 3 files, 2 text documents (license & readme) and the third is: iwlwifi-6000g2b-6.ucode
I need help on how to install this driver and the steps needed.
Thanks.

As stated previously I would urge you to migrate to another Linux OS that is more oriented to your needs as a new user. Certainly, Ubuntu 10.04 LTS is one you cant go wrong with. Crunchbang has been mentioned too. You may try to load these onto a USB key as Live and try to see if the issue has been resolved prior to installation. Also, it is worth knowing exactly what networking /wifi hardware you are working with. Go to the command line and type lspci and that info will be listed (along with all the other pci hardware that you have on you machine). Learning the command line basics and even basic shell programming will help you in all of you Linux endeavours.

Regards

I'll have to agree on the 10.04 plus you still get another yearr of support for no more than it would take to install. Well worth the time.
