To monitor your connection speed, you can use netmeter:

In another thread I read that Clearwire has told a customer that tests from irishisptest are unreliable. I don't know the background to this.
But if in doubt, I advise you to use netmeter instead.
It loads on startup and stays running in the task bar. I have been using it for a few months and highly recommend it.
Handy for saving screen captures and pasting them when sending those emails to Clearwire asking them what's the story with their speeds(and they usually don't respond!!).
Oh, and make sure you include the date and time on the screen capture graphic.
By the way I switched to a new ISP recently. The speed is supposed to be about the same(as what Clearwire advertise). But when I took a screen capture of the new ISPs speeds, it's about 6 times faster. Unbelieveable, the contrast!
