Having same issue.
Keeping cordless phones away not helping.
All new devices anyway.
Still have three other Wireless connected Hp PC using linksys usb wireless gg devices and hey do not loose connections....so I am assuming no problem at Linksys router. Really getting annoying that the Network keeps auto switching to either ethernet or the Paralelles NAT.
I see many posts about this issue so I am begining to think that them their airport cards and not playing well for alot of people.
I've starting having this problem lately on my G5. I don't know what's causing it. It just seems to disconnect randomly. Sometimes, it'll be fine for 40 minutes..or an hour, then it just disconnects.
My logs include the following cryptic messages:
Jun 30 04:55:01 Macintosh kernel: AirPort: Link DOWN (AP deAuth 0)
Jun 30 04:55:04 Macintosh launchd: Server 0 in bootstrap 1103 uid 0: "/usr/sbin/lookupd": exited abnormally: Hangup
Jun 30 04:58:45 Macintosh mDNSResponder: Couldn't read user-specified Computer Name; using default “Macintosh-00145126A608” instead
I haven't been able to determine the cause, but it's getting frustrating. Hopefully someone will eventually post a solution.
I am experiencing the same random disconnects from my wireless station -- even when I am a few feet from the router. This is definitely a software issue and it started to occur after the 10.4.10 update or the Airport update. Here is what is shown in my system log when it occurs:

I am having the exact same issue with a brand new MacBookPro 2.2 ghz. Keeps dropping wireless connection. I must restart computer to get connected again. In addition, I am getting very slow response time with the internet.
I have a Dell I have absolutly no problems with. All support keeps telling me is to reload OS. This is getting so very frustrating. Is there a fix to this issue.
No, we are not by a microwave and only have new cordless phone.
About a page back there's another thread about this same problem.
I have the exact same problem. I suddenly have no internet connection, I have to turn AirPort off and then on again.
I have Windows bootcamped on the same machine, the disconnect happens there too, I have to rescan for networks to get it to reconnect.
AirPort has serious issues.
If it's happening in both Mac OS X and Windows, that means it's either something in your environment, your router or your machine.
The easiest way to eliminate the latter as a culprit is to make an appointment with your local Apple Store's Genius Bar and take your machine in. If you can surf without issue on the Apple Store's network and their diagnostics turn up nothing, it's not your machine, which points to either your router or your environment.
Make sure that your router has the latest firmware available from its manufacturer installed; that has cleared up similar issues for many people.
It may be an environment issue in that this latest Airport update broke compatibility with 95% of the routers on the market. Look at all the threads under the networking sections of these forums -- this is obviously effecting a lot of people and it is not due to a misconfigured router.
I am certain this is an Airport problem because I have had zero disconnects prior to this Airport update and no changes have been made to my wireless network. I have multiple Dell laptops and an iBook G4 that have no disconnect problems on my network. However, I have two MacBook Pro's (one 2.2Ghz and one 2.4Ghz) which exhibit this problem and it didn't start to occur until after this update.
Yup, this happens to me too. I have a MacBook Pro that I generally use plugged-in in the same room as our Airport (errr...don't know what type...it's a white Airport UFO). If I disconnect the MBP from the power to take it into another room, a few seconds later it drops Airport. One way to get it back is to turn off Airport via the menu bar, then put the machine to sleep. I then have to wait a while before waking it up -- I can't wake it up immediately, or this isn't going to work. After waking it, I turn Airport back on and get back to whatever I was doing.
Or, I just reboot, which is a heck of a lot faster.
What's strange is, this disconnect-from-power-and-lose-Airport problem doesn't seem to happen much if I disco from power in other parts of the house. Pretty much only from the power in my office.
