AirPort Slows/Drops Out. Anyone still having this problem?

I am creating a new topic in hopes of seeing if there is anyone else out there having some of the problems originally documented in the "Airport slows/quits, CPU usage high, restart necessary" thread. I do not have the power plugged/unplugged symptoms described here, but here are the symptoms I do have and what I have tried to do to resolve them:

- After ~4 hours of uptime, my airport connection will start slowing down, usually to around half a megabit of throughput, which slows not only the internet but also my local area network. Mounting a server over at around 70kb/sec downstream is unbearable!

- After ~24 hours of uptime, my airport connection will begin to drop in and out

- This happens on multiple AirPort Base Station networks, with graphite, snow, extreme, and express models of the base station

- This happens on both 802.11b, b/g, and g-only networks

- This problem is not RAM related in my case. I CTO'd my powerbook with a 1GB chip from Apple, and have added an additional 1GB chip from TechWorks. Pulling out either that chip or the Apple chip does not resolve the problem. Installing 2GB of Apple RAM or TechWorks RAM has not solved the issue.

- Turning AirPort on and off does not fix the problem, the only thing I have found that fixes it is a restart

- It is not related to Bluetooth being on or off

- The AirPort 2005-001 update does not help or hurt this issue

- OS X v10.4.3. I have tried reapplying the 10.4.3 combo updater to no avail. Ditto on the AirPort 2005-001 update.

I'm pretty desperate for some help here! Is anyone having similar symptoms and/or know of a solution to this problem?

Update folks-

I have tried checking "Internet Robustness" when I click on the airport icon in the upper right hand corner, and I have since been on airport without and faults.

Let me know if that solves ur problems?

Hi all - I am having a very similar problem. I have a Belkin 54g router. When my powerbook is using only wireless, surfing the web is terribly slow. Sometime after clicking on a link it might take 20 seconds before the existing page disappears and the new page loads. If however, I cable directly to the router everything is great. I have tried using my Airport Express router (instead of the Belkin) and have the same problem. Turning interface robustness on also has no affect. As for signal, that is not a problem as I am only 10 feet from the router. My windows PC using only a 11g wireless connection also works great so I have pretty much narrowed this down to my powerbook wireless.

This is a long shot, but sometimes IPv6 configurations can get in the way of DNS resolution working quickly and hence slowing down everything else.

Check to make sure that it is disabled in both the Airport and Ethernet panels of your current Network configuration (System Preferences, select Network, and then pick Airport and Ethernet from the drop down menu and click on "configure ipv6" then switch it off, for each.)

I woke up this morning with the same setting as last night, (internet robustness on, airport on, ethernet off) but it still hung. This *****!

Apple needs to get on the ball about this! This is proving to me that Apple does not care about their clients!
