I have a dsl connection coming in to my home. The dsl line will go into the modem then the ethernet connection on back of the modem will go straight to my hub and was able to share the connection will other pc's on my lan, but now im using a cisco 2924 switch and when i try to connect the modem ethernet port to the switch i get no activation lights at all. I try straight and crossover cable's but no luck. Is there something I need to enable on the switch to make it work. I got my hub to work by enabling mdix button which work fine, please help, thanks.
