Hey, ATM I have my home network like this... Click to view full-sized image! Hosted by UGBox Image Store Now, I want to upgrade to Gigabit ethernet- seeing that two of my PCs support it (Server and my main Desktop) - so I can do my weekly backups a lot faster between these two. Currently my Billion 7402GLM assigns IPs via DHCP, and this seems to work fine through the, what I think is a 10/100 8 port Switch... all the PCs on the network get the necessary IPs and can access the internet fine. What I want to know, is can I just buy an 8 port Gigabit switch? Or do I need an 8 port Gigabit router? To summarise: * Billion 7402GLM w/DHCP * 10/100 "Switch" (pretty sure it's a switch) - allows all PCs connected to it to get an IP via DHCP from 7402GLM, and can access the net fine. * Want to replace 10/100 "Switch" with gigabit version... so do I need a Switch or a Router? Thanks.
