Why does my computer say that it's connected to the internet when I can't actually access the internet?!?

I am a Comcast customer - and I have a complaint about the customer service and the lack of ability to fix a problem that you are charging me for! Specifically - to fix our problem with the internet.

On Tuesday 9/1 my husband began having problems with connecting to the internet at home - when trying both the Wireless and Wired connection he was unable to connected to the internet even though his computer was showing all signs of being connected (ie, the small computer icons were blinking and said "Status: Connected" when they were clicked on/moused over). At this time (9/1) - I was having no problems of connecting to the internet at home on my work laptop - so we figured the problem was with his computer.

On Wednesday 9/2 - my husband called Comcast and spent 1 hour on the phone trying to trouble shoot problems to see if there was something he could do to fix the problem - and the end result was that they told him it was a problem with his computer.

Wednesday 9/2 evening - I come home from work with my work laptop that I'd be using all day in the office with no problems - and was unable to access the internet via our home wireless or wired connection EVEN THOUGH my computer showed all signs of being connected (ie, the small computer icons were blinking and said "Status: Connected" when they were clicked on/moused over).

All signs point to a Comcast internet problem - when NEITHER of us can connect to the internet even though both of our computers show signs of being connected at the time. Especially since my work laptop was working fine all day - and is currently working fine right now at my office. We called Comcast again on the evening of 9/2 and spent over 30 minutes of having someone basically tell us it HAD TO BE a problem with our computer.

How could that be the case if my computer is working perfectly fine today - even though it was "supposedly" broken last night? To top if off the customer service rep was unwilling to send anyone out to look at the problem before NEXT TUESDAY - and was very rude about how "we were causing the problem" and that "we'd be charged $50 if a service rep comes out and finds out nothing is wrong."

We should NOT BE PAYING for a service that doesn't work!! It's unacceptable that you are continuing to charge us for internet during the time that it's down and that you can't send out a service rep in BOSTON to fix this until next Tuesday. There has to be more than one service rep in the Boston area - I find it hard to believe that not one could come and take a look at this this evening or tomorrow morning.
