Hello, list!
I have IBM ThinkPad R40 laptop with Intel 2100 Wifi card.
# lspci -nn -k |grep 2100

It is uses non-free firmware which was installed automatically during
system setup from Debian tarball downloaded from here:
http://cdimage.debian.org/cdimage/unofficial/non-free/firmware/lenny/current/
Under continuous load (# apt-get dist-upgrade), wifi card is breaking
connection very quickly:

So, wifi connection goes up and down frequently. In addition, there is
not visible interruption during regular web browsing.
In Debian Lenny that wifi card works stable and smooth but I need
Squeeze for some reason.
Please, help to troubleshoot that hardware disaster.
Thanks in advance for your time and effort!
