    So i'm not sure if this is a hardware or software problem (on my macbook pro side or network side) but every 5 minutes or so my internet will stop working and i'll need to unplug the ethernet cable and plug it back in. I'm assuming it is having trouble renewing the IP as it is set up dynamically. Any advice would be appreciated, thanks

    That doesn't sound like a problem with your Mac. Are you using a router? If so, try bypassing the router and connecting straight into the modem. If the problems go away, it's safe to assume that the router has a setup problem or has hardware issues.

    What kind of broadband connection do you have?

    Cable - connect to modem like previous poster said

    DSL ? if you have 1) a newer modem with the PPPOE on it, then go straight to the modem

    2) if you have an older modem where the pppoe is on the router, you may want to try some other things before doing this check.

    1) change cables - its the classic "is it plugged in" ethernet cables can get flakey at the connectors
    2) plug into a different port on the router. Switch ports on a router canports go bad, if this solves your problem just leave it plugged into the other port
    3) try connecting wirelessly. If you have a router, its probably also a Wireless AP, so give that a try

    Other things to check. Look at the routers connection status screen. See how long its been up.

    And last, but really the FIRST thing you should do is reboot. REBOOT EVERYTHING. Router, modem, computer, ethernet attached printers.

    Then turn them on in this order
    1) modem
    2) when you get a green cable or dsl light
    3) turn on the router.
    4) then all the routers dhcp clients (pc, mac, printer)

    Hope this helps.

    Don

    p.s. another thing to do is to plug an old router in and see how it does. somebody you know must have an old B router around.

    For a Macintosh Computer, to release and renew your IP address, is this the method you are using?

    1. From the Apple Menu, click System Preferences.
    2. Click Network.
    3. From the Show pop-up menu, click Network Port Configurations.
    4. Click in the checkbox in front of the Network configuration you want to release to remove the check mark (Built-in Ethernet or AirPort).
    5. Click Apply Now.
    6. Click in the checkbox in front of the Network configuration you just unchecked to turn the configuration back on.
    7. Click Apply Now.
    8. Link to the Network page to login and register your computer.

    If you have not yet tried this, hopefully it helps!
