NOTE: Some cards also provide an 802.11 Ad-Hoc mode. This really isn't just there to confuse you, but to accomodate the fact that there are different implementations of "Ad Hoc" networking supported by different manufacturers:
802.11 Ad-Hoc is the newer implemenation and requires cards to be set both to the same channel and have the same ESSID in order to communicate.
Ad-Hoc is an older implemenation and requires only that cards be set to the same channel and ignores the ESSID setting.
We recommend that you use the "802.11 Ad-Hoc" setting if your cards provide it, since it's slightly more secure.
If you are trying to set up a network of all wireless devices and do not have an "Access Point" to connect the wireless network into an Ethernet network, you will need to set your cards to operate in "AdHoc" mode.
When you install your client cards, set the wireless Properties as follows:
Mode (or Network Type)
(or ESSID [Extended Service Set IDentifier])
Encryption (or WEP)
If you've set all the above wireless Properties correctly and can't get a connection, check your TCP/IP properties. If you have a DHCP server available on one of the wireless LAN clients, you can use it. Just set the wireless card's TCP/IP properties to obtain IP info from a DHCP server (or obtain info automatically). Be sure that there is no gateway info entered and that DNS is disabled. Sometimes doing a manual Release All / Renew using either winipcfg or ipconfig will get things working, even after a reboot.
If you don't have a DHCP server available, you'll need to set your TCP/IP properties manually. If this is a brand-new network, the Client setup instructions on this page should work. The most important thing is that you have the IP address of each card set to a unique number in the same "Class C" subnet.
Example: If you choose to use the 192.168.0.X subnet, make sure your client cards are each set to a different IP address such as 192.168.0.2, 192.168.0.3, etc. Use a subnet mask of 255.255.255.0
Use ping to test to see if you have a connection.
