Bug#615112: Reproduced with IPW2200BG

[Benda Xu <heroxbd@gentoo.org>]

Hi,

I can reproduce the bug on my laptop (Thinkpad X41 Tablet)

  Network controller: Intel Corporation PRO/Wireless 2200BG [Calexico2]
  Network Connection (rev 05)

Downgrading the firmware version to 3.0 gives a better wireless
connection.
