I have a new MacBook laptop.Even though my Airport is showing a full strength signal Safari keeps telling me I have no internet connection, Network diagnostics has not solved the problem. It will pick up the wireless network at work immediately but I keep getting the "your computer isn't connected to the Internet here at home. I have a netopia Router and my other Sony laptop can pick up the internet without any problem. i have been trying to fix this now for over a month. any help would be really appreciated !

AirPort signal strength is directly affected by things like concrete walls and metal ducting. You might want to change the physical location of the Airport to help with signal strength. Placing your Airport router in a central location based on computer usage location will help a lot.
Also changing your routers wireless channel thru Airport Utility can help. Think of it as a lot of people using the same street, it tends to get a little crowded. So changing the street means less traffic.
The antennas in the Macbook Pros have had an issue with reception due to the aluminum housing of the laptop but, should still receive decent reception just not as much as a plastic Macbook or plastic PC laptop. It could be possible that the antenna's cables have become disconnected from the Airport Extreme card inside your Macbook Pro, that the card itself is faulty or damaged or that the Antennas themselves have been damaged in some way. As always make sure you have the latest updates and have installed any driver updates from Apple regarding your Airport Extreme card. Here's an article that may help eliminate any wireless interference that may be affecting your signal strength.

Try turning off Airport. Your computer may be finding a wireless network and automatically switching to it, and getting an intermittent signal. Just a guess, but for a good ethernet connection you want to disable the Airport searching feature anyway. Open the System Preferences application, select "Network" and right on the top left of the resulting window there's a pretty big button that will either say "Turn Airport On" or "Turn Airport Off" - just turn it off if it's not already ...
Hope this helps!

Have you checked your system preferences, network settings? You have to tell the mac to use airport or ethernet. It may be setup to use the hard wire and not airport. You should see a link to turn on airport in the upper right corner of your screen. I think you can turn airport on there.
Check to be sure that your network connections are set to automatic(control panel->network connections then right click on your wireless connection go to properties- tcp/ip click on that and check there.
First of all... Unplug the modem, unplug the Airport (WiFi router) and turn off the Airport connectivity in your MacBook.
After 5 full minutes... Plug in the modem.
Wait 2 full minutes... Plug in the Airport.
Wait 1 full minute... Turn on the Airport connectivity in your MacBook.
After all of that...
If you're still not back up and running and you're using an Apple Airport, open the Applications folder, open Utilities, open Airport Utility.
If you're using any other type of WiFi router, use the Network Diagnostics button that should show up in the web browser window when you try to go to any website.
You should check to see if you have the connection set to static or to scan. Your computer could be set to scan, and so when it recieves a stronger signal, even if it is for a second, it will disconnect from the signal you have current. You can go to system preferences , select NETWORK, go to show, then AIRPORT, make sure your signal of choice is at the top of the list.
