10.6.5 and wifi issues

Since I upgraded to 10.6.5, my MacBook Pro (Early 2006) cannot connect to my USR9110 (802.11 g) access point.
From 10.6 on, there's been always troubles when resuming after sleep, but now even at startup the connection goes timeout.

All other devices (an iPhone,an iPad and a MacBook Pro (Late 2006) with 10.5) work perfectly.

I tried rebooting, changing the wifi channel, updating the access point firmware, turning on and off airport, resetting the SMC, switching to WEP, switching to WPA, switching to unencrypted. Nothing changes, connection timeout.

MacBook Pro 1,1, Mac OS X (10.6.5), early 2006

I am having this exact same problem. I am new to the Mac Family since I just purchased a 13" MacBook Air on Black Friday and I love everything about it but this. I have been spending the last month researching this issue and have tried everything possible and had no luck. I contacted Apple and they acted as if it was just my specific computer with issues and told me to take it back to the store and exchange it which I did today and guess what... it is doing the same ** thing! They should know this is a serious issue that needs to be fixed immediately and it really upsets me to call and they just act like it is something wrong with our ISP or my specific MacBook with a faulty airport. I purchased my MacBook Air from Best Buy and I have until January 31st to return it and I am afraid that I might actually have to do so because I can't stand this much longer! If anyone figures this mess out, please let me know ASAP. I really do love my Mac and would be sad to have to return it. Thanks!

Have tried everything so far and finally decided on connecting #1 mac to DSL model via ethernet cable and setting internet sharing on my #1 mac. Have a PC and #2 mac connected via #1 mac for internal network and internet access. It appeared to be completely stable. However this afternoon, I'm finding that it's not. The #1 mac is disconnecting to the PC and #2 mac but is re-connecting very quickly again. My PC torrent downloader recovers OK. That's why I thought it was all working. Downloads on my #1 mac were working. However, general downloads that cannot survive an outage are all failing within minutes. The #2 mac is also failing when the application cannot handle a quick internet outage. Transferring of files on my internal wireless network is almost impossible as the connection is not stable enough to complete any transfer. Everything I do points to the wireless on the mac being the problem.

What does Apple need to have to take action on this? Given that you cannot contact Apple via e-mail with fully documented evidence, I'm becoming very 😟

Yup. Apple's ProKit 6.0.1 update was causing problems for me and I posted on an Apple forum. I got an email from an Apple engineer asking for more system details from my System Profiler.

However, to date, there has not been a patch to ProKit fixing the issue. But at least there was not the frustrating silence I have experienced with this wifi issue.

So when you took this in to the apple store they can try to surf on their wifi, I assume they did this. But if not you could go back and have them demonstrate that it works (or not). More than likely it will work fine. The reason they do an immediate swap is that this has to be the most time efficient for you and them.

So assuming this works at the Apple store, I would venture that your wifi router is not working well with the Mac. The standard suggestions here are to update your wifi router firmware. The N spec really just came out. Apple has programmed their wifi cards to follow (strictly?) the N spec as published. But wifi vendors started selling N routers well before the spec issued and I feel this is the root of many problems. Maybe time for you to get a new wifi router (depending on its age and your comfort with updating router firmware).

ctmurray,

I suppose it could be a faulty card or antenna connection as you suggest, but I think that would be highly coincidental considering the high traffic on this thread. Also, my Airport was working normally until the 10.6.5 update - no problems. Again it would be a huge coincidence that the Airport card decided to kack at the same time my 10.6.5 update was complete and my Mac rebooted.

But thanks for the suggestion, it can't hurt to rule out all possible culprits.

For those who are interested, I have looked into buying a new Airport card and installing it myself... check these links:

Coincidences happen so that is why I suggested checking the hardware. You could go to an Apple store where the signal is strong and really should work with you Mac without issues. Check the signal strength with a genius bar person, a bad card might show up weakness relative to new machines.

This link is to a post of mine where I list all the software / Mac side things to try. The ones on the top of the list have been confirmed by other posters to solve their problem. The issue of course is each case is somewhat unique so there are several things rather than one thing that have worked. You might have already tried them but it does not hurt to link you:

Yup, been there done that. The Genius was rather condescending about it really. He said "the card seems to be functioning normally." Now that I think of it he sounded a lot like the HAL 9000 computer just before the antenna array failed on the ship. Too funny.

Anyway, my trip the the Apple Store was a complete waist of time.

My guess is there will eventually be some sort of update dealing with this where the release notes say something like: "Fixes a issue with some Macs causing the Airport card to fail" or some some such language.

So here is the rub, I hope you are correct. Having followed these threads for a long time;


1. Every OS update results in people with the same problem (every 10.x update has threads along these lines). Their wifi worked and does not after the update. So there is something about an os update that seems to mangle something (the process of writing the update rather than some bad code in the update). So all the suggestions about repairing permissions (a known problem with updates), or tossing out preference files, or removing/restoring network locations...do seem to help many. Many who switched from WEP to WPA worked. Many who actually looked at their wifi network for conflicting routers, microwave ovens, cordless phones have found something new/amiss. So what I am trying to say is that with all these known causes (and solutions) how is Apple going to put this into the next OS update?

2. Several of the top posters on network connections will tell you Apple is not going to check their wifi compatibility with every model of router (and every age of router). So Apple will make their router compatible with the N specification. As we saw with antennagate with the iPhone, Apple has the test facilities to make sure they meet specs. But there is some evidence that non-Apple routers implemented draft versions of N or guessed at how to implement and thus might not be in perfect N compliance.

So you could be correct, Apple might including in an update some code to help. But I am concerned, so I keep following the thread and listing my list. The items on my list where I state they have been confirmed by posters means more than one person has written back to say that fix solved their problem.

Because the computer worked at the Apple store, the employee is correct, your card is working. In a known good N wifi location the computer and software worked.

Personally I have had an airport card go bad, and have had three routers just up and die. So hardware stuff happens.

Also, I have been trying to find other repairers of Apple equipment who might have experienced wifi issues and solved. So far no luck finding anyone like that having solved this problem. Usually known OS bugs arise in such large numbers that some of these more skilled people find the issue and get to Apple for a fix.

ctmurray,

Wow... lots of great insight in your post. Here are my thoughts...

*The Problem:*
After applying the 10.6.5 update, while I still get wireless reception, I have to be within 10-15 feet in order to connect to any router, any further away and the reception drops and disconnects. Previously, I was able to be anywhere in my house and get a consistent, strong signal. Also, before the update, I could see many of my neighbours' networks, whereas now I can only see my next door neighbour's. Since the update, something has changed the Mac's ability too see networks or has severely hampered the Airport's range.

Observations:
I agree that Apple can't be responsible for 3rd party routers and the quality of their firmware and age etc. However, I travel a lot for work and since the 10.6.5 update I have had very poor wifi reception on open networks where I have never had issues before. Many of the hotels, airport lounges, coffee shops I frequent have always had very reliable wifi connections, but after this particular update, at least in my case, I am not able to connect at those locations... and I mean this nation wide - literally! I find it hard to believe that all of these routers are not up to an industry common standard that Apple demands, especially since I see other people with a variety if different laptops having no connection issues.

Hardware:
So the next possibility, as you suggest, is some sort of hardware issue: Either a fault in the Airport card or the wireless router. I have replaced my 1 year old router with a new one, even though no other computers has a problem seeing and connecting to my network. I also took my Mac into the Apple Store where a Genius tested my Airport card (doing something in terminal) and concluded that the card is functioning normally. But, it may be that there is some kind of undetected fault, so if a patch is not forthcoming, I may buy a new Airport card to see if that fixes the reception problem. The purchase of a new router had ruled out a dead or dying wireless station.

*Interference & Attempted Solutions:*
I have adjusted the router settings to see if there is some kind of interference issue from a cordless phone or another router but with no luck. A have also applied the various fixes common to the multiple 10.6.5 Apple Discussion threads and other non-Apple sites. None have worked. I have yet to do a clean reinstall of my entire system becasue that is a big job and I just don't have the time at the moment. But the fact is, an update should never force a user to do a reinstall from scratch or break crucial functionality of the machine.

Conclusions:
I agree that there does seem to be problems with every 10.x update and not just with wifi... while updates solve known bugs, they also introduce new ones, that is just the reality of computers. And a simple Google search suggests that this is an ongoing issue. However, I am not sure if this is due to it being a new problem so there may be a flurry of new posts, but it does seem that there are a much higher concentration when it comes to wifi issues relating to the 10.6.5 update. This is why my best guess is that there is some kind of compatibility problem with 10.6.5 and some Mac/Airport card configurations. In the past I have had applications break due to bad drivers or due to updates only for a fix to appear at a later date (sometimes that even means waiting months). At this point I am pretty sure it is not a router issue; There are simply too many routers involved for all of them to be faulty or incompatible. If I decide to replace the Airport card, I will post the results here.

Dec 26, 2010 11:34 AM in response to Sweejak

I have a first generation 17" MacBook Pro (2.16 Intel Core Duo). I also had a problem with flaky wifi connectivity. I tried uninstalling and reinstalling my airport drivers, trashing my system configuration files, repairing permissions and voodoo rituals, but nothing would keep my internet connection from going down (airport menu would say it was connected, but pinging my router would reveal timeouts...)

The only thing that has worked for me was to run Disk Warrior to repair my directory. It was a measure I tried out of desperation. I don't know why it worked, but it did, and now my internet connection is as fast as ever. If you have a copy of Disk Warrior, you might want to give it a try.
