Periodically (about twice a month) I cannot connect to my Linksys router (WRT54GS)...the connection times out on my MBA or it says Unable to Join Network on my iPhone.

If I unplug my router and plug it back in- EVERYTHING works. Recently I found out on my iPhone that if I go into settings and I select to Forget this network and I then set it up again it works and is a better option than having to go to my router and plugging it out and back in.

My question is if there is a similar option to forget a network on the macbook air that completely resets it? I have tried going into the AirPort settings and clicking the minus button on that specific network but that does not do the trick.

Is there a way to forget all networks and completely reset the Airport on a macbook air?

Macbook Air, Mac OS X (10.5.4)

    I have been having a similar problem. I find that if I don't use my MBA for a while (like I put it to sleep for more than a day or so), when I boot up, I can't find any networks.

    After spending a while on the phone with AppleCare about this one day, we found that if I delete the network settings folder (sorry, I'm not at home to double check the folder name for you, but I believe it's HD>library>prefs and on mine it's the LAST folder in that list. You have to enter your password to delete it.) Then if I reboot, everything will work fine.

    Until I don't use the computer for a little while.

    This is obviously frustrating, and I'm at the point I'm about to reinstall 10.5.

    The last folder in my Library for Preferences is SystemConfiguration...it has a bunch of .plist files- is this the same folder you are referring to?

    I lost connection again recently and I am wondering if it is an interference issue- each time I am able to find the SSID I am just unable to connect because of a connection timeout.

    Recently I could not connect to both the iPhone and MBA at the same time...my PC's were unaffected- it must be an interference issue?

    ...and again, all it takes is for me to unplug my Linksys Router wait 10 seconds and then plug it back in and everything works. I am just looking for a better/permanent solution.

    yes, SystemConfiguration. That's it, I just double checked.

    I'm not positive your problem is the same as mine- but that's what worked for me. Can't hurt to try...

    Sounds like your router burps and chokes and until it is revived it won't accept connections.

    "Stuff" happens.
