Internet Help

ISP is SBC Services. We pay for 6 MB/PS download speed. I set up the modem so it goes to the router first, then then the crappy desktop, and then my laptop. My laptop confirms that the frequency is 802.11n. My dad and I called AT&T and they said they could not help us and that our hardware is the problem. I know for a fact it isnt. My laptop has Gigabit ethernet and the internet goes Modem -> Router -> Laptop -> 10/100 Desktop. Doesn't go from desktop to router to laptop. I can't even watch a YouTube video in 240p without buffering every 20 seconds. Please, anyone have an idea? We are going to replace the network card in the desktop to gigabit but that doesn't explain the speeds my laptop is getting.
