Internet disconnect very often in using AirPort Extreme

Hey,

Last week I bought a brand new AirPort Extreme base station in order to improve my wireless network in my apartment.

I have D-link ADSL modem (model 2760u) that connected to the AirPort Extreme..

So the problem is very often I see that the modem is sync and the Internet is connected but in the airport network I see that I'm connected to the wireless but for some reason the AirPort Extreme report that the Internet is disconnected (again the flashlight is green in the modem)

Restarting the airport resolve the problem for few hours but its very annoying to do this over and over again.

The airport is now working in bridge mode because I get airport massage for double NAT)

Can I get any help please?

Thank you!

OS X Mountain Lion (10.8.2)

A "double NAT" condition is indicative of having two routers with NAT enabled in series. It appears that your D-Link modem is actually a combination ADSL modem & router. Typically, in this configuration, you would want the downstream router (in this case the Extreme) in bridge mode.

Once in bridge mode, the Extreme should NOT lose Internet connectivity periodically. If this still continues to be the case, I would suggest a complete power recycle of your networking equipment, and then, reconfiguring your Extreme as a bridge.

Please post back after doing so to let us know your results.

In addition to the expert advice from Tesserax, in order to configure the AirPort Extreme in Bridge Mode to work correctly with your D-Link modem/router.....

Open Macintosh HD > Applications > Utilitiies > AirPort Utility

Click on the AirPort Extreme icon, then click Edit

Click the Network tab at the top of the window

Make sure that the setting for Router Mode is set to Off (Bridge Mode)

Click Update to save the changes and allow 30 seconds for the AirPort to restart

Then, power cycle the entire network by powering all devices off

Wait a few minutes, then start the modem/router first and let it run a minute

Start the Airport Extreme next the same way

Continue starting devices one at a time until the network is completely powered back up
