iMac has slower internet

Below are three screen shots from 3 different macs in my house. My internet should be 50 mbs, and two of the three get close to that. My 2007 iMac only gets in the 20's, and I was curious to know if anyone has an explanation for this.

Macbook Air, 2010

iMac, 2008

iMac, 2007

Put the MBA next to the iMac and run the test again on the MBA, unless this is what you did?

Plus, I don't know the exact iMac year, but there was a generation where you had to pay a little amount to enable the "n" radio on the machine. Check, maybe your '07 iMac needs this.
