I have recently got a mtnl broadband connection. I am told that i can connect to any computer in the range of 30 mts using wifi. I tried with my laptop and it is working fine. My desktop is not wifi enabled. I was earlier using a reliance netconnect+ dongle to connect to my desktop. I have disconnected the same (the dongle remains with me). Can I use the same dongle to connect via wifi on my desktop? What else do i need to connect my desktop to the internet via wifi?
