So my brother in law has comcast Internet and he let me join his network and boy was it lightning fast. I could download movies left and right and I would get stable Internet connectivity and speed. So I got comcast too. The problem that I'm having is that when I download stuff, it doesn't download at the fast speed like his. For example he's paying for the 12MBs plan and so am I. When he downloads something the speeds range from 6mbs to 15mbs. When I download something the speeds I get are about 1.5-5mbps. Why is that? Is there a setting I should change on my time capsule to make it spit out the Internet faster? Also when my laptop is on my PC which is hard wired to the time capsule and my iMac which is wireless get slow Internet as well. Anything you guys recommend?
