user ID help

I had to reset the router for my cable connection
after a power failure this morning. I happened to
choose a user name that has a space in it when
resetting the encryption settings. Something like
"wallyu DR" (minus the quotes). In any case, it works
fine for Windows, but I can't connect to the router in
Linux. 
  
I could reset it again, but what can I do if I choose
to keep the current user name?
 
I'm using a Linksys v. 2.8 WUSB11 USB wireless
transmitter.
 
Any ideas? I'm thinking that the naming convention
used in the command line might work, but I'm not sure.
(ex: $home> /mnt/windows/My\ Documents)
  
Thanks for any help. :)
  
Alex
