i have been having random dropped connection for the last few months but ths past week it has gotten MUCH worse. i upgraded to 10.5.2 but it didnt solve anything, and could have possbily made it worse.

now when i try to log on ichat it connects, disconnects, connects, disconnects over and over until i can no longer log on b/c its timed out.

also at times i will have full strenth from my wirless network but it will act as if i am not connected and not load pages or log onto ichat.



wtf is going on? this is seriously annoying...
 
having wireless probs here too.

Such a shame... I hope it's not my router..cos I do manage to connect, but there are times which the Macbook just refuses to detect my wireless and connect to it.
 
The keychain app...

In seeking more stability within my home network, In the keychain app I created a new keychain in my user field and in the login field, my main network keychain is located in the system section. In the new keychain I renamed the Kind of keychain to:"Wireless network password" while the "name" "Wireless" is the name of your network, and the location of the new keychain is the same of your system location, in the area called "where" you find the information to be copied over, in the Access Control tab add the following files: apple80211agent and systemUIserver located in core services and the system prefs app. save changes, do one for your Login section and another for your user section. see if this improves stability, so far its been days since I did this and I've trying it out and the machine connects after sleep and restarts quickly.

Even though I'm not an expert, I think this makes a lot of sense. I don't have any signal drop-outs on any of my 2 macs. I use a D-Link DIR-625 router (apparently known to be problematic with signal drop-outs) and there is only 1 other wireless router in my neighborhood...so as per this article, channel interference is not a problem for me and as I said, I don't have any drop-outs and never had (no matter Leopard version). It will be interesting to see people reporting on that.
 
ill add to this…

Wifi had been solid with 10.4 no problems but ever since i jumped to 10.5 wifi has been driving me crazy. Right now using 10.5.2 router wrt54g firmware tofu.

What i learned

When using network diagnostics (boy did apple bury this) when I had problems connecting to websites it would tell me I had a green connection between the my computer and the ISP but not to the internet or server which I find odd. Turning off the airport card and on again gave me all greens again until it fails. But no other computer is affected so its not my router or firmware it has to be something local that is affecting the connection.
 
im experiencing the same problems on my MBP.. i have spent weeks trying to fix it.. narrowing down every possibility.. new router, internet connection ect.

The way i get it working is by restarting the computer and router and the same time
 
Seems the above link is stating his connection issue was due to interference from other Wireless networks. I don't think that's the case with most of our connection issues. I know for sure there are only 2 networks in my area and we are on different channels (I setup both networks). I still have drops on my Mac while my wife has no problems on her Thinkpad.
 

I am also having this issue. The exact issue is that the connection slows down to almost 0 after using the slingbox for a while or copying a large file over the network.

I haven't tried the fix in this link yet, but I have noticed that there are 10+ wireless routers picked up by my MBP. I will try this when I get back home and see if things aren't better.
 
My new (refurbished) MBP seems to be having trouble with only secured networks. It usually takes a few minutes to load pages and I constantly get "page cannot be displayed" screens. I know the problem isn't with my network because my windows based PC works fine, as well as another windows based laptop in the house. But I took it over to a friends house the other day and it worked flawlessly on his unsecured network.

So I have narrowed the problem down to my MacBook Pro + secured network. Are there some airport settings that I'm missing that would help stabilize my connection?
 
I've had less and less problems with my MacBook and wi-fi dropouts since Leopard .1 and .2 updates
 
Is wifi dropouts a really common problem? If so, why not complain to Apple and, if dropouts occur soon after purchase, return a computer or demand a refund for the purchased Leopard upgrade.

That said, I have not had problems with dropouts in Leopard (10.5.1 or 5.2) on a G4 PB.
 
Although I still have problems screen sharing, Leopard to Leopard, the suggested switching off of IP6 has helped a lot. No connections dropped in the last 24 hours.
 
Makes a little bit sense as to why a drop out might occur to all network devices.

However, when a drop out occurs, it is just me that it happens to - my Windows based flat-mates stay connected.

Also, Tiger was fine.

That's also true with me, all the awful windows machines in my house have fine wireless.

does anyone know how to disable other networks from being scanned? (ie the ones you dont want to use, so that the one you do want to use will be the only one it tries to connect to). surely this would get rid of some of the interference.

It isn't the scanning that causes interference, it is the fact that there is two or more routers operating on the same channel and frequency.

Your Mac will only scan for available networks when you click the AirPort drop-down box or if you aren't connected to any wireless networks.
 
I switched...

I switched to channel 2, instead of 6 which is what most of my neighborhood is using according to iStumbler, and so far its been connecting without issues. But its good to go back on this big thread and READ some of the hints posted, I read some of the recent posts and it seems that some are posting as if this thread just initialized, so my advice would be to go back and apply or try some of the good info posted.

Last night, I tried some of the tips in the previous posts. After changing my security from WPA to WEP and changing the channel to a non-used channel, all drop-outs seemed to have stopped.

The one problem I'm still having is copying large files via the finder from my G4 desktop (wired) to my MBP (wireless). When trying to do this, the first 10 megs or so copy within a second or 2. After this, things slow to a crawl, copying about 5-10 megs per minute. As a comparison, I tried copying the same file via scp and the entire 400 MB file copied in about a minute. This points directly to Apple's implementation of network file sharing.

Has anyone else seen similar issues?

I'd still like to try turning off IPv6 and trying again. I'll try this tonight and let everyone know the outcome.
 
Dropped connections

I also faced the dropped connections -- but only after upgrading to the latest Mac OS X release. I have a new MacBook bought the day after Christmas with Leopard pre-installed. It worked perfectly with ATT DSL for 6 weeks. Then, I updated to 10.5.2. Immediately, my wireless started dropping regularly (DSL model is a 2WIRE790). So, off to the internet I went to find a solution.

I can't find it right now in a Google search, but earlier this week I found a post on a sight by someone named "Lori" so credit goes out to her for discovering this and I hope she's reported the bug to Apple.

She discovered that Back to My Mac was someone erroring and removing the "default" dns path in the dns route tables. Each time default is removed, the wireless goes out. Default shows up again after a recycle of the airport card in the computer.

Anyway, tonight, my Mac was dropping every 2 minutes or so. It was very annoying. So, I tried what she suggested, I turned off Back to my Mac -- something I never turned on in the first place! Sure enough, my Mac hasn't dropped a connection in over three hours now. From once every 2 minutes to none in 3 hours!

It seems -- right now -- to have worked for me. I hope it works for you as well.

Wait, so you never had back to my mac enabled but after the update it was already enabled? Interesting!

Where do you enable/disable it? I will go home and check if it's enabled on my machine...

Nope, I sure didn't enable Back to My Mac. So, my guess is that the Mac OS X update did enable it. I never use .Mac to back stuff up, and I always make sure with every new machine to turn these "features" off.

It's now been another hour with no drops.

You can find anything using spotlight. Just open system preferences, in the spotlight box type "Back to my Mac". It will highlight .Mac. You'll find it in a tab in there.

Now, if you're not a .Mac member, then this is not the solution to your problem because you can't be "Back to My Mac-ing" without .Mac. But, if you are a .Mac member -- give it a shot!

Good Luck.

This random disconnect/failure to connect issue is driving me nuts. I keep running into the following: Getting prompted to join my network, even though the keychain already has my network name and WPA password; getting disconnected for no apparent reason, even though my MBA is about 4 feet from my AirPort Extreme base station; "connection timeout" after about 3 seconds when trying to connect; and having to turn AirPort on my MBA on and off several times before it will connect. I've already tried adjusting virtually every network setting I can think of (I am not switching back to WEP), but only my MBA, with its Leopard 10.5.2, has issues connecting and staying connected to my wireless network; all of my other network devices, even 50 feet away, can connect to my AEBS and stay connected without any issues.

I just now added SystemUIServer and Apple80211Agent to both entries for my network in Keychain Access. Hopefully this will help.

Apple, if you're reading this: GET THIS FIXED NOW. You can't blame this issue on anyone else.
 
Clayj, that's exactly my problem, just as you described. It is very frustrating for iMac G5 that I just installed Leopard on today has Airport problems while the iBook running Tiger is just running as smooth as ever.

No matter what I change to try to get the iMac working, the iBook connects just fine. It's a challenge just to try to sync the settings because they switched certain things around (i.e. Interference Robustness in the menu bar).

I'm with you that they get a fix on this pronto!
