is the card for laptop och Desktop computer?
802.11g is the standard for wireless U have 3 standards 802.11a, 802.11b and 802.11g
and 11g is the most common and the most secure and easiest to use
11g is divided into channels from 1 to (I think its 16)
11b is more diffecult to use
and 11a you don´t wanna use
good luck with the wireless network

802.11 is the IEEE protocol for Wireless Ethernet.
802.11a was the first, and ran to 5Mb
802.11b came second, and ran to 11Mb
802.11g is the current standard and runs at 54Mb
In each case a single-vendor solution (i.e. the same manufacturer for the Access Point and WLAN card) can often double the data rate, hence your 3Com 108Mb solution. But to get 108Mb, you MUST purchase a 3Com WLAN card.
Obviously, if you have a desktop PC, you will require a PCI card. If you have a laptop, it's a PC Card that you need.
An 802.11g device is backwards-compatible. You may find that running 'g' at 108Mb is difficult out at the range extremes, and you need to switch down to 'b' or even 'a', as this will practically extend your range. This isn't as big a problem as some would make out, however, unless you're transferring lots of files between the wireless device and another wired device (at 100Mb) on the same LAN (Local Area Network - i.e. what's in your house). If you're using the wireless network to share your internet connection around the whole house, then any wireless connection is likely to be good enough as the limiting factor will likely be your internet connection speed, especially if you connect at at least 'b' level.
When configuring your system, you need to change from the default settings, and make sure that you configure the card and the access point in the same way. How you do it is up to you. I changed my access point's address away from the default, changed the "admin" password, changed the SSID, set Wireless Encryption on with a nice long key, set MAC filtering, and changed the transmission channel. All of this will be in your documentation.

Hey GilesGuthrie how about this one? http://www.3com.com/products/en_US/detail.jsp?tab=features&pathtype=purchase&sku=3CRDAG675
I think that's the only PCI card they have available for desktop.

Can someone please help me? I keep getting a IP Conlflict and I don't have a friggin clue on what to do.
I have SBC DSL and it's hooked up to my 3Com OfficeConnect Wireless. Yes I have a desktop with a wireless PCI card. My friend told me to enable DHCP on my AP but that didn't do anything.

Try changing your computer's IP address as assigned by the router? Go to Network Connections>Local Area Network>Properties>General Tab>Internet Protocol (TCP/IP)>(Highlight Internet Protocol)>Properties.
If it is set at obtain an IP address automatically, then change it to use the following IP address: 192.168.0.x. For x try different numbers from 2 on. Subnet mask use 255.255.255.0. Leave everything else as is. If it is set to "use following IP address", change it back to obtain IP address and obtain DNS server automatically.
Good luck and hope that helps

Looks like a good one. I like the antenna on a cable - means you can move it away from all the interferance your fans/psu etc generate.
IP address conflicts are caused by more than one machine on the network having the same IP address. Assuming you have a 3-node network (2x PCs, 1x Access Point), move the last sector of the IP address of the machine claiming a conflict by 4 up or down (ensuring you stay between 0 & 254). Then reboot.
When you're able to connect to the Router, configure it to act as a DHCP (Dynamic Host Configuration Protocol) server. It is probably defaulting to one of the private network adddresses, 172.x.x.x; 192.168.x.x., or 10.x.x.x. Set the "Scope" to lie within that range, and set it to "50 - 200". So, if your router's address is 192.168.1.1, set the Scope to 192.168.1.50 - 192.168.1.200.
On each client PC, in the network settings, set the TCP/IP settings to "Obtain an IP address automatically". This will cause each PC to ask the router for an IP address, which will then ensure that the router avoids conflicts for you.
