Upgrading to 10.5.5 breaks wifi?

...Can someone comment if they have had wifi issues since 10.5.5?

My 17" MBP works flawlessly when it comes to wireless issues.

Probably not the comment you wanted to hear...Are there any Apple Stores in Singapore that you can take your unit to?

1.83 macbook pro core duo.. wireless was working fine (dare i say flawlessly) up until i upgraded to 10.5.5 and the latest airport update (2008-004)... it is very annoying.. thousands of people complaining about the same thing for so long and still no fix or even so much as some acknowledgement from apple that there is a problem.. apple support gives a bunch of bogus fixes for the problem and acts like its something with my system and seems to not be aware of the fact that thousands of customer's wifi interruptions began after those last updates.. very frustrating

I have a new iMac and new TimeCapsule. Things were running OK'ish until I upgraded to 10.5.5 when network access started to deteriorate in an unpredictable fashion. The network would slow, and grind to a halt at times. Signal strength would vary markedly. At first I suspected the TimeCapsule and I had this replaced. the problem persisted. I bought a new MacBook Pro (I needed to transfer machines anyway) and after a brief honeymoon period of a day the problem returned. I trawled the internet and followed the tip to delete /Library/Preferences/System Configuration and indeed that would provide temporary relief but not for long.

The new MacBook Pro was installed and had the settings transferred from the old iMac. The TimeCapsule has been reset to factory settings. This has cost me days of work time.

There are countless reports of 10.5 WifI problems. Why have Apple not publicly acknowledged this and at least provided us with some reassurance that this is being addressed?

Same here, have exactly the same Wi-Fi issues with my MacBook Pro 15" (early 2008) after the system updates. Very very annoying to say the least, it almost renders my Mac useless as I am not able to use the Internet for more than 10 minutes every time I get a signal.

It's definitely not a problem of my wireless router because other devices (including my Apple TV) just works fine, and I experience the same issue with connections to another router at work.

I've read other posts on this forum and it seems that downgrading back to 10.5.2 is the only proven solution. However, I wouldn't want to do it as it would involves too much effort re-installing the system and restoring all my data and apps. This is my only Mac, and I use it at work and at home at least 16 hours every day.

Much appreciated if any one could share any other solution.

Hi belleliu,
I just wanted to warn you that reinstalling 10.5.2 may not be sufficient. I have installed 10.5.2 on an external disk and obtained nothing.

G.

I am experiencing the same problem - my MBP1.1 (early 2006 model) worked fine - Since latest update, the only way wireless works is if I sit next to my base station. If I move more than a few feet away from the base, the signal drops out. Intermittently, operation restored. Problems appears to begin when the laptop goes to sleep. On wake up, signal strength first appears good, then drops out. Resetting machine, PRAM, permissions, etc had no effect. Will try 10.5.2 after the holidays.

If I continue to surf the web as I walk away from the base station, the link is maintained. If the laptop goes to sleep, the link shuts down, and will not reconnect at wakeup.

I also having this issue.... is it possible to roll back an OS update or do I have to reinstall my whole system from my last TimeMachine backup?

If I do a fresh install from my 10.5 DVD, can I have it install the updates up to the last update release before 10.5.5, or can I only update to the latest release?

I was looking at the software update history on my Mac and I'm starting to think that the issue may not have been the 10.5.5 update but actually the 2008-004 Airport update as the date I installed the OS update predates by several weeks my wifi issue where as the update for Airport was much more around the time I started having issues.

Thoughts?

I am virtually certain it was the 2008-004 update for my MBP 2.2. The good news is I have turned off wifi encryption security on my access points and am using only MAC filtering and everything works great on my own networks. I try to connect to another network with WPA or WPA2 and the wifi thrashes and dies quickly. Try it. Go with caution that MAC filtering only is not secure, especially if sloppy network shares are used.

Beyond reinstall, I would like to know how to rollback 2008-004. I am stubborn and know its possible! LOL.

Apple, get your head out of your @#$! and fix this. I too have had problems with my early 2008 MacBook Pro. Wifi under Vista x64 on the same machine however works just fine. I've gone through many various routers, fixes, etc. and nothing has worked.

FIX THE **** PROBLEM APPLE! ****, at least acknowledge it.
