Hi There,

I have an Intel iMac and after updating airport i've been having problems with it. I'll be using the internet and all of a sudden it will just disconnect and cannot detect any network connections. Now, i've seen the other posting already about fixing this problem, and I have done what it says to fix the problem by moving the system configuration folder and the com.apple.systempreferences.plist file. After I do this, it works for a few hours but then i have the same problem again. The folder and the file is recreating and i have to follow the same steps and move them again, but then every few hours it keeps getting recreating. Is there something that i can do so i'm not constantly moving the files around and having to re-setup my network. Is there a way to reset Airport to the way it was before i installed the update?
Thanks

    "Is there a way to reset Airport to the way it was before i installed the update?"

    Of course you can erase your hard drive and reinstall up to 10.4.7, and not go any higher. The problem is the 10.4.8 update, or some part of it. The many other updates recently posted for different apps are not part of the cause, so those updates can be installed.

    "Is there something that i can do so i'm not constantly moving the files around and having to re-setup my network."

    Yes, once you've followed the "restart twice" instructions involving preference file deletion, it appears that by turning off AirPort before letting it sleep, restart, or shut down, those two files will not get the same corruption recreated. Afterwards, you should be able to turn on AirPort and after a slight delay of about six to eight seconds AirPort will be able to reacquire your network.

    If you forget to turn off AirPort before sleep, restart, or shutdown, then those files will again be corrupted and you'll have to go through the process all over again. I ran through it about 50 times, changing this and that, and that's all I could come up with.

    Hopefully someone else out there with a different perspective will be able to figure out what else needs to be done.

    The files will always reappear, because they belong there. You are only deleting them to get rid of the corruption.

    It looks as if you did not first apply this solution from the main page of Intel-based iMac Support:
    http://docs.info.apple.com/article.html?artnum=304482
    Ignore the title of the article and just follow the instructions - it got rid of my temporary disconnect problem, which in every respect was the same as you describe. After applying the solution from that article, but not before, I had to proceed with the process of deleting the two preference files. I suspect it just has to be done in that order.

    I have a similar problem and put up a new post topic before I read this one. My airport signal level seems to slowly die out over time (1-3 hours) until I have no signal at all. Turn it off or put it to sleep for a bit, and when I resume I again have good sinal again for a while. Seems to be heat related. Waiting for suggestions.

    Not sure if this is what's happening with you or not, but check in your router settings to see if you have a setting for "Client Lease Time". This is the amount of time your computer will have with the ip address asignment on the LAN side. The way mine works is in minutes. So I set mine up for like 425 mins, which corresponds to like 7 days. Anyway, once that lease time is up the router and your computer negotiates for an ip address again and during that time you WILL NOT have internet connectivity. Hope this helps.

    QuickDraw,
    Wow, which isp requires you to arrange for your own lease time? First I've heard of, I believe, or have I been missing something?

    If you look at my post a little closer you'll see that I was not talking about "Internet Service Providers" (ISP), but in fact I'm talking about the IP Address on the LAN side that the computer(s) negotiate with the routers. 192.168.1.100 <--- you know LAN side ip's, not the internet side ip address which the persons Internet Service Provider provides. If your router doesn't do this, then this is the first time I've heard of any router not doing it. There is such a thing as DHCP on both sides you know on the ISP "Internet Service Providers" side and the LAN "Routers" side. Unless a person chooses to use STATIC addressing on the LAN side, but that's a different story. I think static addressing is a BIG PAIN, and will never use it again. You mean to tell me your router doesn't have "Client Lease Time" feature on it? All of mine over the years have always had that feature.

    I just noticed in your post that the amount of time until you have a problem with signal is only 1-3 hours. If this is correct then my other post is probably not going to help you as the LEAST amount of lease time, with my router anyway, is 24 hours. I suppose it wouldn't hurt to check it out though.

    This post looks/sounds a bit defensive and argumentative. Sorry I'll try harder NOT to do this in future postings
