Currently using a Linksys WRT54GS v6, with DD-WRT firmware on it. I also have a WRT54GS2 v1 that I put DD-WRT on, and am planning on switching to that one over the summer at some point, after my room mates leave.
I also have a Netgear WN802T v2 Wireless N access point that I'll be using when I move to my new apartment at the end of the summer.
I like having a friend that gives me free networking equipment from businesses he upgrades lol.
I also have a 5-port D-Link gigabit switch. Can't remember off-hand which one.
