Thanks for reporting this bug and helping to make Ubuntu better.

Can you try this with a 10.04 live CD and see if it finds your wifi?

Also, I am going to move it to the linux project until we know more
about the issue.  gnome-nettool is for running tools like ping, whois,
traceroute, etc., it doesn't do any setup or discovery of network
connections or hardware.

Title:
  Wubi installed Ubuntu 10.04 can't use wireless network

Status in “linux” package in Ubuntu:
  New

Bug description:
  Ubuntu 10.04.03 LTS was installed recently using Wubi in WinXP home
  edition. I used a full partition (26GB) for Ubuntu. Wireless works
  well in WinXP on same laptop. So hardware has no problem. But no
  wireless network can be found in Ubuntu by network-manager or Wicd.
  Manually inputing wireless ESSID and password in network-manager
  didn't help. I have tried all commands related to wireless network I
  can find. The output are as below. It seems wireless card was
  disabled. But I couldn't find way to enable it.

  I may have disabled (reenabled later) wireless card in WinXP when
  installing Ubuntu. So I reinstalled Ubuntu using Wubi to check if it's
  the problem. But this time I kept wireless enable. The problem is
  still same in new Ubuntu. So disabling and reenabling in WinXP was not
  the problem. It becomes more like a bug.

  I have not find hardware switch on laptop and never use it. It should
  not be problem since WinXP works well.

  Commands outputs:

  $ rfkill list
  (no output)

  $ sudo lshw -C network
