MacBook Pro drops Wi-Fi connection after upgrading to 10.6.5. Fixed!

MacBook Pro drops Wi-Fi connection after upgrading to 10.6.5. Airport says no IP is detected then suddenly reconnects?

This has been a problem I’ve been troubleshooting for the last month. I’m new to the Mac family and have loved my experience up until this point. I was under the impression that mac’s are supposed to be so user friendly that even your grandmother could use one with out having any technical knowledge. I mean I shouldn’t have to be deleting drivers or reformat my mac because of an OS update glitch? (That’s what the guy at the Genius Bar told me to do.) What I refused to succumb to was that I’m really good with computers. I get at least a phone call every other week from someone asking me for tech support. So I’d like to think that nothing I’ve done to the system would have caused this anomaly.

After numerous attempts of troubleshooting and researching forms I believe I’ve discovered a solutions that seems to be working for me.

Here are the steps I took to create a consistent connection to my Wi-Fi. I believe it was a combination of all these steps to create success.

1.) Changed my router to use G Wireless Only. (I’m assuming this removed any unnecessary frequencies to allow G to broadcast stronger?)

2.) Did a scan on the other networks in my area to find out what channel everyone else was broadcasting on. Copy and past the text below into a terminal window.

sudo ln -s /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resourc es/airport /usr/sbin/airport

This will allow you to simply type “airport” in the terminal window to execute the command.

Type airport –s

This will display all the networks in your area and what channel they are broadcasting on.

3.) Changed my router to use a channel that no one in my area was using. (This helped to make my network stronger and free of interference.)

The last steps will help your home network improve but these next steps I believe helped fix any install errors caused maybe by the 10.6.5 update on my mac.

4.) Boot your Mac into safe mode by holding down the shift key while booting.
5.) Open System Preferences and Click on Network.
6.) Click the drop down menu from Locations at the top of the screen. Click edit locations..
7.) Create a new location by clicking the + and give it a new name.
8.) Delete the old location by clicking on the old locations name and click the – to remove.
9.) Reboot
10.) Open System Preference and click on Network.
11.) Click on the settings sprocket next to the + and – and click on Set Service Order…
12.) Drag Airport to the top of the list of devices then click Ok.

Now this last step is what seemed to eliminate the issue. I hardcoded my IP address to my network. This way my computer will always use the same IP and not have to search.

13.) Click on Advanced under Network.
14.) Click on TCP/IP. Click on the drop down for Configure IPv4 and change it to Manually.

15.) Fill out the fields with your IPv4 Address: 192.168.1.1xx (x=whatever number) Subnet Mask: 255.255.255.0 Router: 192.168.1.1 (All of these settings are pretty standard for most home networks.)

16.) Click on the drop down for Configure IPv6 and change it to Off.
17.) Next click on the DNS tab at the top.
18.) Click the + to add a DNS Record.

To find your DNS Server open a Terminal window by launching Applications --> Utilities --> Terminal

Then Type cat /etc/resolv.conf

(There is a space between cat and /. Without it you’ll get no such file or directory.)

This should return two addresses. Your ISP’s DNS Servers.

19.) Add both records to the DNS and click Ok.
20.) Click Ok then under Network Click Ok.
21.) Reboot router then Mac
22.) Fixed my connection issue

The symptoms I experienced eluded me to believe that something with the DHCP is going into an idle then disconnecting. Before when DHCP was set to automatically assign the network signal would time out then searchers for a new IP resulting in Airport displaying No IP is detected. By setting my IP to a fixed address I still notice a slight drop in bandwidth at moments but because of the assigned IP I never loose connection. I can now stream video, play games, chat all without getting disconnected.

I believe this fix will work for my home network but I also noticed this issue at work so for each location that I connect for the time being I’ll create each there own location and hardcode the IP address to that network. I’ve been reading that 10.6.6 is coming soon so maybe this will be resolved for good in the next update.

Let me know if this helps or if you have any questions.

Best of luck.

Update...

After almost 2 weeks with no connection problems to my wifi by hard coding my IP address to my network my connect is now dropping again.

Troubleshooting...

I've added google's DNS sever 8.8.8.8 and moved it to the top of the the list of DNS servers. Appears to be working fast again with out dropping connection.

I'll see how long this lasts for but it does appears something with the DNS is causing this issue after a given amount of time it gets confused and starts disconnecting.

I have been having the same issue for the last two weeks. No real indication as to why it ever began other than I had turned off my router and Airport Extreme Base Station off for a weekend while I was away from my place.

iPad, iPhone, iPod Touch, all have no issues at all with my Airport Extreme Base Station. Can stay connected throughout my living room, bathroom, bedroom, no issues whatsoever.

My 5 month old MacBook Pro 2.66 GHz Core i7 Airport is sometimes perfect, able to connect, DHCP, and browse without issue. Then, for no reason, I won't be able to join my wireless network, or when I can join, I can't pick up an IP address. And then it will connect, pick up and IP, and then it won't browse. No real rhyme or reason to when this will happen, or when it works.

I thought that it was an issue with my MacBook Pro, but then my sister visited with her brand new MacBook Pro 2.26 Intel Core 2 Duo, and while a month ago she was able to connect, DHCP, and browse without issue, this weekend she had all of the same issues I was having.

My XBOX 360 and MacBook Pro have absolutely no issues with the wired connection. Only my WAN seems to have this issue.

Did you ever find anything more to this?

Hey CeeDub,

I haven't had a definite fix yet but I found hard coding my IP address and using Googles DNS server to help keep my connect pretty solid.

I also just did my System Update and notice there is an update for the Airport Utility. Could this be the fix we've been waiting for? I hope so....

I'll test and report back this week...

AirPort Utility 5.5.2
This update contains bug fixes and improvements, including the following:
Resolves an issue that caused the DHCP settings tab to display incorrectly
Resolves an issue that caused the application to quit unexpectedly when automatically launched
Resolves an issue that prevented the network password from being stored in the Keychain when the network on the 5GHz band was named differently

I have exactly the same problem as you CeedubH1, my Macbook Pro automatically drops out when connected to the wifi and must be restarted in order to have ity reconnect. While other devices such as my PS3 and N97 have absolutely no issue what so ever. Glad to know its just not my Macbook, does anyone recommend I take it in too Apple? When I called Apple Care the guy apologized and said it was a faulty network card and that it will promptly be replaced. Would they be able to fix anything if I took it in?

After the update to my AEBS earlier this week, I have not had any success in completely resolving the issue.

Restoring my AEBS to factory defaults helped for what seemed a day, and then drop-off's started happening again.

I haven't been at home long enough until today to attempt a hardcoded IP and a change of my DNS settings, but I also haven't had ay drop-offs today.

I haven't had time to talk to Apple or go into an Apple store, but knowing my experience with an Apple Genius that isn't related to software, they would only offer to replace the Airport card, which would probably take two or three weeks to have done. I use my laptop for work almost all day everyday, so this is obviously out of the question. And since I appear to not be alone in this issue, and seeing this happen with my sisters MacBook Pro, I really don't believe this is hardware related, at least not on the part of the MacBook Pro.

Hi Guys,

I have sort of the same problem since yesterday.

My Macbook pro 13"(10.6.5) won't connect to our home wireless internet connection. My Mac mini, iPod touch, Windows laptop work perfectly on the wireless network, but my Macbook suddenly doesn't.

- It keeps saying (while trying to connect): "Connection failed".
- Using an ethernet cable works instantly, but wireless is just important.

I don't know if it is the 10.6.5 firmware, but this really *****. I am afraid I can't connect to internet at school for example. This problem can only be my macbook because I cant just edit the prefrences, channels etc of the schoolnetwork...

Does anyone have a solution? Doesn't apple know about this??

Sorry for my english, I'm from the Netherlands.

Regards,

@CeeDubH1, @NJayasinghe I believe you guys are correct in assuming this issue is not a hardware issue and more of a software problem. Prior to updating my OS to 10.6.5 I had no wifi issues or drop outs. I am curious as to what model your MacBook Pro is? Did you purchase it within this last year? I'm noticing that this issue seems to be coming up more with the MacBook Pro 2010 models.

I did take my laptop into the Genius Bar and he suggested I try other networks to recreated it which it does. Then suggested to reformat. I don't believe a reformat is the solution in this case as I've read other people already trying this and still having wifi drop outs after upgrading to 10.6.5. They ended up reformatting again and not updating the OS. I also use my laptop for work and backing up, reformatting then reconfigure isn't really an option right now.

I have found ways to help keep my connect working but haven't found a permanent fix. (read previous posts)

*Latest Updated*

The update for the AirPort Utility 5.5.2 did not fix anything. Starting to run out of ideas on how to fix this. Need apples support in identifying what the issues is so they can create a fix.

Dec 20, 2010 11:43 AM in response to broeky

Hi Broeky,

I took my MBP into the Apple Store and the Genius guy was not familiar with this issue. The solutions he suggested did not fix my problem.

-Delete Wifi Account from Keychain
-Run disk utility to verify and repair disk
-Booted in safe mode (hold shift during boot)
-Deleted Network Location and created a new Location
-Moved Airport Extreme to the top of devices
-Reinstalled OS X 10.6.5 update
-Tried other Wifi Networks (issue still remains on other wifi networks)

The only suggestion they gave that I haven't tried yet is reformatting back to stock and updating the OS. I'm trying to avoid this suggestion as a final result as I've read other people trying this and still not fixing the problem. I don't want to waste a day reformatting everything to find out it does the same thing.

If anyone else takes there MBP to Apple please let us know if you find out anything new or if a reformat fixes this issue.

Best,

Eric

If someone can tell me how to reformat it back to stock, I would like to try it out.. I can't do any damage or anything right? It just makes the macbook completely stock, no files, no software only a brand new OS?

The only thing I have to do is backup my 'Home' and stuff? (Software I got on CD).


Btw, there are still no software updates available wich fixes our problem. Apple must not be familiar with this issue I guess...

Dec 21, 2010 11:39 AM in response to broeky

Well guys, sorry to say this but the clean reinstall didn't work for me either...
I'm out of ideas and apple told me that it only could be my airportcard, so I'm getting that fixed and hopefully I can work with my Macbook properly again.

Just now I have to figure out how to do my school and work assignments. Does anyone know how much time a repair will take?

Dec 21, 2010 10:14 PM in response to broeky

Broeky,

Having a full reinstall fail to resolve the issue doesn't really surprise me. The test that you should have done was to see if the issue went away under 10.61-4, and then to see if it came back under 10.6.5. This would have allowed us to see if the issue was in 10.6.5. Unfortunately, I do not have the time to format, reinstall, and then restore my MacBook Pro from my 800 GB Time Machine backup.

I think that what with the issues my sister and I have been having with our MacBook Pro's, and what issues Apple was having in the beta versions of iOS 4.2 on the iPad, Apple needs to have a discussion with their wireless networking team.

I just hope that enough people will be able to come forward about this and get Apple to resolve the issue in the next system update.

Dec 21, 2010 11:18 PM in response to CeeDubH1

Well if its any help, I've done the clean reinstall a while ago and found it unsuccessful so then got on the phone to Apple. They basically did some tests and came out with the conclusion that it was the Airport Wireless Card (their opinion).

Sorry for not quoting names but for the person who asked how long it would take for them to have your laptop back and ready for use, only four days which in my opinion is fairly good unless you need it everyday for work or school. Also they called me this morning to further enquire about the issue as they found no fault with the Airport Wireless Card (which was the conclusion we came too on this thread). While giving further details about the issue I also thought to enlighten them of this thread which the service technician had never been aware of in the past. In the meantime please pay attention to this thread until Friday, which is when I hopefully will be picking up my laptop from the service center and hopefully will be able to let you all know about what was done to resolve this issue.
