Step to setup wireless network

Below are some of the commands, which are used to set up a wireless network setup in linux machine or fedora. Follow the steps listed below to setup the linux network.

Steps tobe followed:

1) Identify the chipset of the wireless device
2) Choose the right driver
3) Install the driver

 # lspci 
 # lspci | grep -i net
 # iwconfig 
 # dmesg | grep wlan
 # dmesg | grep iwl
 # iwlist scan
 # ifconfig 

Try to figure it our whether the required modules are installed on your machines or not? If you are unable to find the required module for your kernal from the above command then install the required modules by using the below command.

 # modprobe -r intel_wmi
 # modprobe -r asus_wmi
 # dmesg | grep iwl
 # yum install iwl3945
 # su -c 'yum install iwl3945'
 # su -c 'yum search orinoco'
 # yum install iwl3945-firmware
 # cat /etc/modprobe.d/blacklist.conf 
 # dmesg | grep iwl

Once you install the required modules then try the below commands.

 # rfcomm 
 # rfcomm -a
 # rfcomm connect
 # rfcomm show

 # dmesg | grep iwl
 # iwconfig 
 # lsmod | grep iwl
 # iwconfig 
 # dmesg | grep wlan0
 # dmesg | grep wla
 # iwlist scan
 # ifconfig 
 # cat /etc/sysconfig/network-scripts/ifcfg-lo 
 # iwlist

All the above command are just copied from my history, when I tried to configure my wireless network setup. If worked fine for me and finally I was able to set up my linux wireless network.

 # cat /etc/sysconfig/network-scripts/ifcfg-lo 

OUTPUT:

 DEVICE=lo
 IPADDR=127.0.0.1
 NETMASK=255.0.0.0
 NETWORK=127.0.0.0
 # If you're having problems with gated making 127.0.0.0/8 a martian,
 # you can change this to something else (255.255.255.255, for example)
 BROADCAST=127.255.255.255
 ONBOOT=yes
 NAME=loopback

 # iwlist scan

OUTPUT:
