Motorola SB6120 Router to Cisco WRT610N, and a mini Cisco SD2008 8 port 1 Gig switch. I also have a Belkin Home Base and a Linksys WRT54GL - but those are more of clients on the network than network core devices.
I'm not thrilled with the Cisco WRT610N's performance. At times it's wireless side can seem to hang, and cause disconnects.
