Yes the firewall can definitely get 'in the way' of communication...... what
firewal software are you using.
I presume the Linksys wireless router is assigning the DHCP address
correctly to both PC and printer?
Are you using a cordless phone in the same household as the wireless-g
network... if it's on the same frequency, this can also definitely cause
communication problems... as can a microwave. You might want to also ask in
the networking newsgroup, as this is a networking issue, rather than a
printing one.
