Mysterious Airport dropouts solved?

Back in Germany I don't have this failures anymore. So it seems the connection of chinese internet provider caused them back in China. Here in Germany the airport express (The first edition) works perfect!

I too have having dropout/slowdown problems with my airport express. When pinging I was getting normal times with huge times every second or so. I had tried all the usual things like changing channels, and other airport prefs etc etc, but nothing seemed to solve the problem. Anyway, a few minutes ago I just noticed that in the console log I was getting an error every few seconds, saying 'JavaScript says: powerString is screwed up', after a search for this phrase in google I found out that it's a jwire widget problem, deleted jwire and all seems fixed. When pinging I'm getting normal times. It may be coincidence and this may not solve problems for other people but if you've been having airport problems, check your console log and try deleting jwire. Hope this helps!!! Ian

I've just been running into poor and dropped connections recently with my Buffalo wireless G router. I downloaded iStumbler on my Powerbook and walked around the house and found the problem. In the room where my router is located, I was getting 3 different neighbors signals all above 50% signal strength on channel 11 and another 3 on channel 6 and one on channel 1. My router was also set to auto-channel - and whenever it would switch to 6 or 11, my signal would be less than 60% at best only 6 feet from the router - and sometimes unable to connect at all. Upstairs near my daughters computer, I had 4 signals each about 70% on channels 6 and 11 and her connection would drop constantly. After some experimentation with manually changing the channel - I settled on channel 4, which now gives me 90%+ signal strength about anywhere in the house. So this problem isn't limited to Airport base stations, Leopard - or anything else really. Anyone who's got neighbors with WiFi could run into this.

Actually the problem with the dropouts lies in the IPv6 settings. Try to set it to "Local link only" instead of "Node" or "Tunnel" under the IPv6 tab in the Advanced settings of your Airport-tools.

I went from several droputs a day to none at all for the three months I've used this setting.

This explanation makes sense. I spent 5 years working on wireless-enabled applications awhile ago, using Cisco Aironet 802.11b cards in an environment which was largely outdoors. No buildings to bounce off of made for really annoying issues.

Anyway, one issue we found was that our applications had a high rate of lost network connectivity. It got to the point where I had to code in extensive debugging to correlate the issues: the Cisco drivers (not firmware!) had a low tolerance for AP switching.

That is, our debug pings dropped every time the wifi card felt it needed to "scan for a better network".

Once Cisco released newer drivers, we were able to turn that scan setting off. And voila -- problem gone. If we could get that kind of control over the Mac's wifi, that might do the trick.

I had constant dropouts, and I tried EVERYTHING. Then I downgraded my AEBS to 7.1.1 firmware and I have been 100% smooth sailing ever since. I run 3 computers (2 mbp & 1 PC via WDS Airport Express, an XBOX360 hardwired, and 2 iPhones)

I think it is an issue with the 7.2.1 firmware. I'm serious, as soon as I downgraded it everything was perfect!

I'm on 10.4.11 and have this problem, too. I tried setting a fixed channel in the past, that didn't help. I also changed addressing and am hoping that's it, 'cause it's been fine since then. Using 192. addressing now. But all this is questionable because my iPhone never loses the connection in the first place. Just my mac.

So i deal with this on a regular basis to say the least. what i have found works if all els fails is to isolate the issue. if you are using a newer mac with 802.11n and some non apple router and you get disconnected try turning 802.11n off on the router. if you are using WEP security step in to the new millennium and switch to a WPA security. also other issues i see with people that are using WEP is the pass key if you are using an ASCII make sure it is 13 characters and if you think that 10.5.2 seemed to make your computer all of a sudden stop working test from the install DVD (thank the engineers for this handy 10.5 feature) if it doesn't work chances are it is hardware, or your $49 router. or of you like many others are running VMware or Parallels chances are something didnt jive when they messed with the air port frame works and it hosed your system config file so head on over to /Library/Preferences/SystemConfiguration and drop that bad boy in the trash restart and try again. the cards are working it is most likely a setting on the router, or a whole lot of 2.4 GHZ interference, so get rid of that baby monitor and old school cordless phone. hope that help you all out

That makes sense, any time mine drops out another Network shows up in the menu, I thought they might be related.

The Azureus-AEBS thing is a function of the IPv6 support. Set it to Link Local and it should work.
