Hey guys,

 

A couple of weeks ago, I bought a new AirPort Extreme and have been using it in combination with my MacBook Pro 15 (i7) for a while.

 

The problem is that the internet speeds seem to decrease over time. Normally I get 7-8 MB/sec download speed, but after a couple of days that speed just drops to 300-500 KB/sec. The solution to the problem is simple you can either turn off the AirPort and turn it back on or you can simply do a restart from the AirPort Utility. It always solves the problem and the speed goes back to its usual 7-8 MB/sec.

 

Can anyone tell me what is causing this issue?

 

Thank you in advance.

    There is a remote possibility that your new AirPort Extreme Base Station (AEBS) is not compatible with your ISP's service; however, in most cases this issue can be resolved by performing a complete power recycle of your networking equipment, as follows:

     

    I would recommend that you do the following as a minimum:

    • Power-down the modem, AirPort base station, and computer(s).
    • While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
    • After the base station resets, go ahead and power it back down.
    • Power-up the modem; wait at least 10-15 minutes.
    • Power-up the base station; wait at least 5-10 minutes.
    • Power-up your computer(s).

     

    In this basic configuration, computers connected to the base station, either by wire or wireless (as appropriate for the base station type), should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options.

    If the bandwidth decay is not on the local network, but on the WAN-to-LAN interface (that is across the modem/router interface), then the issue could be one of the following:

    • The Internet service connection between the ISP and the modem.
    • The modem itself.
    • The AEBS

    I would have your ISP run a line test between their office and your modem. If that proves out to be ok, ask them to replace your modem. I am assuming, of course, that they provided you with one.

     

    Once both of these have been tried, and there is still no resolution, either have the AEBS checked out at your local Apple Store or return it for another manufacturer's model.

    I don't think this is either a Snow Leopard or MBP hardware driver issue.

     

    It is normal to have some loss of bandwidth across a NAT router due to the overhead of performing IP address translations, but not as significantly as you are getting. Since you are experiencing this regardless of the router model, makes me suspect of which routers would actually "work" with your ISP's Internet service. Do they provide any recommendations?

     

    I am venturing to guess if you measure the throughput performance of either the prior Linksys or the current AirPort Extreme across the WAN-to-LAN interface and compare it to their LAN-to-LAN interface, I would suspect only a minor drop. One great tool for doing this is jPerf.

    You're very welcome! I'm glad you got it worked out ...
