Assuming wlan0 is your wireless interface....

 
sudo iwconfig wlan0 essid <your_ssid>
sudo dhclient wlan0

Kind regards

Can you please explain this more.

I have the wired internet connection to my desktop and I want to share this internet connection via Wi-Fi to other devices like mobiles and laptops.

You have given no diagnostic information here. What did you do ? What happened ?

Actually Sir I have tried to typing the commands

sudo iwconfig wlan0 essid rushikeshtade
sudo dhclient wlan0

It took some time to complete execute the second command.

When it get executed I tried to search the network on the mobile and my laptop but these devices were not showing the wireless network. So I came to decision that these commands are not wortking.


At the same Time I have tried typing the command

ifconfig
