Router is a Cisco 1840 Series. Our ISP controls the router, The router is set to 10 Mb's half duplex. Is this a common thing for the routers to come from the ISP's configured like this? If so, is there some reason why they do this? The half duplex setting really puzzles me. Why wouldn't it be set at full duplex?
I'm wondering if the reasoning is, well it collapses down to a T1 which is running at 1.5 Mb's, so 10 Mb's is fast enough, why run at 100 Mb's.
