I am getting only 30 mps dl using a wired connection on desktop. on my wireless laptop it is up to the normal 200+. I have xfinity 200 service.

Some more details might help like what router you have? 

If you're using wireless you're not just using the cm700 as thats a modem only device. 

What router do you have? 

What wired speeds do you get directly connected to the modem?
