Question 2wire Wifi adapter not detected on laptop w/ubuntu7.04

HI, I am a Newbie w/windows-Dos and some Cisco router experience.
I installed Ubuntu Feisty on a Dell C610 Laptop including a dual
boot setup w/WinXP+Ubuntu.Works fine except 2wire 802.11b/g wireless adapter
is not seen--even w/iwconfig and sudo.The USB is seen but comes up as
"unclaimed".I suspect I need to identify,locate,download and install the
appropriate driver.I also need the step-by-step to accomplish all 4 tasks! The Wifi adapter works fine in Windoze.All other
equipment on laptop can be listed when I open a terminal window.
Need to complete install and put results in a hardware review for others.
Thx in advance!

If you open up a terminal and type (as root): lspci look for soemthing that looks like:
03:00.0 Network controller: Broadcom Corporation BCM94311MCG wlan mini-PCI (rev 01)

You can take that information and look for more detailed specifics on what driver you'll need to install, and how to do it. In the example above, the chip is the Broadcom BCM43xx. Another example could look like this:
02:00.0 Ethernet controller: Atheros Communications, Inc. AR5212 802.11abg NIC (rev 01)
which would be for the Atheros chipset.

lspci will show you alot of stuff, so you'll have to look through it to find the entry for your wireless card. With that information, you can search through the tons of tutorials and guides for getting that chipset to work

EDIT: After a quick search, I found another Dell C610 laptop saying this from lspci:
03:00.0 Network controller: Intersil Corporation ISL3886 [Prism Javelin/Prism Xbow] (rev 01)
So, you could now search for guides on installing Prism drivers and getting them up and running. (Here's a hint, use ISL3886 and Prism during your searching)

EDIT2: Another thought would be to try using it via ndiswrapper. This way you use the Windows drivers, and ndiswrapper provides a mash for them to work with linux. Personally, I'd look around to see if you could get it going with native linux stuff first off, before giving ndiswrapper a go.

I tried lspci -v, lsmod, ifconfig, route -n, sudo lspci -v and
cat/proc/bus/usb /devices and the Devices Manager in Gnome. This laptop has an eth0:3com corp 3c905c-TX, a USB controller:Intel Corp 82801CA/CAM USB(Hub#1),a PCI,a ISA,a IDE and an Intel Modem for dial-up. However, Ubuntu will not see the 2wire adapter in the USB port nor list a driver. When I switch into the XP partition the 2wire works perfectly using a Windows/System32/Drivers/wlanUIG.sys
driver instead of the Prism driver originally provided by the AT+T
CD.The 2wire is not mentioned on the Ubuntu Device Manager for networking purposes but the 3Com Eth0 NIC is detected and works when setup. I have heard something called an Orinoco works to make the 2wire work but know not if it does nor how to load and install such a beast if it does work. Suggestions?
