any expert help???

i just brought the WRT54GL v1.1
do i need to 'RUN THE CD FIRST'?
wat is the purpose to do it?

btw, how am i get the original firmware of this wireless router?
if i flash to DD-WRT, it will void the warranty?

may i know where can i get the DD-WRT firmware?
how am i go to flash the firmware?





** my comment:
can MX510 gather all the necessarily info in the first thread?
like where to download the new firmware, guide and etc?

thanks for ur feedback..

btw , i brought RM220 only
it mean i flash to any 3rd-party firmware, i still got warranty right?

ok i try it first if i cant found it i ask again
