what nwclient are you using? where is the roaming profile to be stored? have
you set policies so you dont end up with 2gig profiles (especially ie cache

this
list then come back if you have further issues. Yes, that means complete
this list .....

DNS setup properly
that speed/duplex on *everything* is hardset, & hardset correctly
latest drivers for everything (nic/chipset/controller/etc)
check cables, make sure everything is cat5e certified, not using flat
