Do I need a firewall?



Hi,
I am running Windows XP (Home) edition and have a wireless network at my
home. I use the Netgear Wireless router MRF-814v2.

I have seen reports on Internet which say that Service Pack 2 adds more
security.However I don't want to apply Service Packs which I feel slow the
machine.

Do I need a separate firewall like ZoneAlarm or Norton Firewall installed on
my machine to protect my machine? Will the router firewall itself be enough
for protection?
My other home computer runs Windows ME. Does that also need a separate
firewall software?

Please post your comments.

Regards,
MK
