stop reading if you're easily bored by computer network lingo: i've been using a spare wireless belkin router as an ethernet switch/hub in my bedroom for a few months now. previously i had a dedicated cisco network hub, but it was an old model that only had 10base-t ports. the only problem with the belkin hub was it was on a different network than my main linksys router, i.e. computers on the linksys had 192.168.1.x ip numbers, while anything connected to the belkin fell under 192.168.2.x. why is this important? because computers on different networks can't see each other (i won't be able to share files).
