samba - Apr 2005 - Problem using roaming profiles with wireless clients

Hello,
I have a Linux server acting as a Windows PDC and we're using roaming 
profiles. Wired clients connect fine and upload/download their profiles. 
Wireless clients do not. I also have RADIUS running on the Linux server 
and the Wireless AP is configured to authenticate against the RADIUS 
server as well, using the windows login information. I enabled verbose 
debugging on the RADIUS server, so I could see exactly what is 
happening. When the wireless clients try to login to the domain and 
download their roaming profiles, the client will hang at the login sceen 
for a few minutes, then report that it could not connect to the server 
hosting the roaming profile. Only after I click "ok" does the client 
send the username and password to the RADIUS server for authentication. 
The problem seems to be timing, so I was hoping someone may know if and 
how I can configure the XP clients to bring up it's wireless interface 
before attempting to download it's roaming profile. I know this isn't a 
samba issue, but was hoping someone might know a Windows fix.
