    I bought my iMac in summer 2009.

    This is my problem:
    The airport of my imac, running osx 10.5.8, seems to have a problem. It is connected wirelessly, via a D-link 2.4Ghz router, to the internet. But the internet runs slowly. Sometimes more slowly than other times. Sometimes the internet connection seems to just get dropped, although it still shows full bars, and it takes a lot of patience or the turning-off-then-on of the airport to resume.
    The imac is fully updated.

    What I don't undestand:
    I also have a macbook, running osx 10.5.8, and I don't have any problems with its wireless connection and speed. Even when I put the macbook right next to the imac, side by side, the macbook's internet speed is much better. Both with firefox or safari. The airport settings of the imac and macbook are identical. The DNS settings are the same.

    What I've tried:
    I tried switching to the open DNS addresses, and that has helped a bit, but the imac still lags behind the macbook and connection is still sometimes dropped or just horrible.

    What I suspect:
    When I bought the imac, it came with osx 10.5.6. Later I upgraded to 10.5.8. When I was on 10.5.6 I used a cable connection to the internet, and I only tried going wireless after the upgrade. So I can't say for sure whether something got screwed up in the upgrade, but I suspect that's the case from my reading of the experiences of others which I found through google.
    My macbook pro was bought with 10.5.8 pre-installed.

    What I would like:
    I would like the wireless speed of my imac to match my macbook's. I can't get a cable for the imac.

    Thank you!!!!!!

    It could be a faulty wireless card. The wireless card in my MacBook Pro that I purchased in 2009 went bad after about 18 months. Start a constant ping to your router and see what's going on.
