Mmm... the only noticeable change I recall from lenny to squeeze 
regarding the network it was this:

http://wiki.debian.org/NetworkManager#NetworkManager_in_Squeeze

But this is for setups where N-M handles the wireless adapter and given 
you are manually configuring the network, you better try with tehse 
guides and manuals:

http://wiki.debian.org/NetworkConfiguration

Mu wild guess is that you first need to configure the wireless card 
accordingly to your setup, that is, by manually providing all of the 
settings.

Better if you can provide the syslog so we can review what's going on 
(you can omit any sensitive information).

I think this is well explained in the above referred docs :-)

(hint: each network interface can be set to auto/allow-hotplug...)
