Setting up a wireless internet connection without router is usually done using adhoc network. It is a latin phrase sometimes used to describe a quick fix which can be temporary. Small businesses generally establish ad-hoc computer to computer network, if they do not have access to a router. They use a wireless internet session to do different works like checking email, attending a web-based meeting or browsing the web for a short period of time.
Many are unaware that, if they have Windows Vista, Windows 7 or Windows XP installed in their system, they can build their own wireless network connection at home and even in office without having a wireless access point or wireless broadband router. This helps save money, building this kind of network is also referred as Ad-hoc network.
In the text box, labeled as “give the network a name and choose the security options” enter a name for your ad hoc network. From the drop-down list, select the “security type” either WEP or WPA2. Choose WPA2 instead of WEP as WEP is older security and it is less secure when compared to latter. However, there is a drawback that WPA2 may not work with older wireless network adapters. If one is unsure and wish to learn more about different security type, click on the button, “help me choose”
In the security key field, create a passphrase. This security key should either contain 8 to 63 case-sensitive characters or 64 alpha-numeric characters, you can choose letters A through F.
Once you get the confirmation, that your ad-hoc network is now available in your list of wireless network and ready to use, provide the security key as well as network name to all people, whom you would like to share it.
