| Why and when would you want to install a | | | | advanced tab. Check the box that says enable |
| wireless adhoc network? Well you would want | | | | ICS. Once you have setup your ICS, go to |
| to install a wireless Ad HoC network when you | | | | every computer and configure their wireless |
| do not have the equipment for a wired | | | | adapter like you did the first one.ICS will |
| network; you lack a wireless router and want | | | | act as a DHCP server and assign private TCP |
| to share an internet connection, or a | | | | IP address to your ad-wireless network |
| temporary meeting place where you need to | | | | clients. Each computer will receive a TCP/IP |
| share information.The first type of set up | | | | address from 192.168.0.1 to 192.168.0.254. |
| will be if you do have an internet connection | | | | ICS will also tell the computers on the |
| but you lack a wireless access point or a | | | | network the location of their default gateway |
| wireless router to share that connection. | | | | which is the computer you set up ICS |
| This could be a very common scenario at a | | | | on.Trouble shooting a wireless ad-hoc network |
| business meeting or during a classroom study | | | | can be a head ache. Make sure you set up the |
| session.First, each computer will need a | | | | ICS computer and one client computer. You |
| wireless adapter. Next click the advance tab | | | | will want to check to make sure that the |
| near the bottom right and click (computer to | | | | first client computer has the correct IP |
| computer ad-hoc networks only). Second you | | | | address so type CMD into the run box to bring |
| will need to add your ad-hoc wireless network | | | | up the command line. Next, type in ipconfig, |
| so click add. Fill in the network name (SSID) | | | | you should see a number of 192.168.0.2 or |
| and choose WEP encryption. You will want to | | | | something similar. Next type ping |
| use WEP if are using older adapters and use | | | | 192.168.0.1 or the number of your default |
| WPA if you are sure all the computers on the | | | | gateway. If you can ping it you should see |
| ad-hoc wireless network can handle it. It is | | | | four reply messages.Once you have the first |
| not a requirement to use encryption but just | | | | two computers connected correctly, just go to |
| remember that anyone will be able to join | | | | all the other computers and configure the |
| your network.Because we will want everyone to | | | | wireless adapters the same way. Other common |
| share our wired Ethernet connection you will | | | | mistakes are: leaving the firewalls on, wrong |
| need to enable ICS (Internet Connection | | | | encryption and just general typos.In my next |
| Sharing) on the wired network adapter not the | | | | article I will describe how to set up a |
| wireless adapter. This seems like common | | | | wireless ad-hoc network with-out a wired LAN |
| sense but I have seen many people trying to | | | | internet connection.Sign up for the most |
