how to speed up my internet

Hello, I'm not exactly sure what category this should be listed under so feel free to correct. I am wondering how I can speed up my internet. On speedtest.com is says that I have a 10.71 mbps download and 1.34 mbps upload but for some reason my internet is always slow to load web pages etc. There a quite a few internet connected devices in my house (up to ten (iphones computers, xbox), but not all being used at once of course, with 2 Airport Extreme base stations.) Is this an interference problem or what? Is there a program that shows all internet activity throughout the network so I can monitor it. Please help and thanks!

 

Yes... but how? I have a good speed from my ISP.

 

ok thanks ill try that. Does anyone know of a program that can track what activity is going through my network from all devices to see if something with another device is going on?

 

So if my router was a Time Capsule, I couldnt do this?
