Linksys WRT54G router

[Charles Malespin]

Hi all.. This may be the wrong place to ask, but Im stuck.  I have a
Linksys WRT54G router that I would like to hook up to my wired desktop
running Breezy so that my macbook can have wireless access..  I cant use
the setup disc because it is an .exe file for windows.  I went to the
online setup(entering 192.168.1.1 in firefox etc)  But I have NO IDEA
what to input or anything like that for the DNS, DHCP etc values.  I
have never set up a wireless network, so I have no clue about this..  I
didnt see any real easy way to just use the default values to just "set
it up" and while Im setting it up I lose internet access for some
reason.  Any help or suggestions would be appreciate(the Linksys people
told me to call the "linux help line" because they dont support linux,
so they are obviously no use).  Thanks, 
CM
