Question: MacBook Pro constantly losing wireless connectivity

Hi folks,

Well, I read a ton of posts regarding MacBook Pro wireless networking issues before buying a wireless router last month, and now it's "me too."

Our iBook has no problems whatsoever with dropped connections, but the MBP loses access every few minutes or so. I usually follow a sequence of "Turn AirPort Off"/"Turn Airport On" to cycle the connection, and sometimes this works. It's an almost constant problem. This is a standard configuration MBP.

The router happens to be a D-Link DIR-615, but I've seen enough posts about problems with the Airport Express and MacBook Pros to know it's not the router that's the problem--it's the MacBook Pro (I notice a few similar posts even on the first page of this forum).

Dear Apple: what are you doing about this issue?

Has anyone else somehow resolved this problem? If there was only a couple of posts about this issue, then it might be written off as problems with a specific router, or specific users. But when there's a ton of messages all complaining about the same problem, then it's more likely a significant defect that needs to be fixed by the manufacturer, and won't be fixed by standard troubleshooting procedures of the mundane kind (Tech Support Theater: "Is your router turned on?").

Dear Apple: where are you?

Amazing thread, Apple should address this properly.

After an awful lot of trawling forums I finally found this useful thread.


with tips that seem to of worked, basically clear your network settings, then clear passwords in keychain, then repair hard-drive permissions in disk utility, (mine seemed to fix about 300 airport problems).

or as the guy I now owe my thanks to put it said:

Name: "SouthernDoc"

I posted this in the other thread about this issue in the OS X forum.

This is what solved my problems with WiFi disconnecting randomly, not appearing after awakening, etc.

1. Open network preferences from your WiFi icon in the menu bar. Then click advanced. Delete the network that is giving you problems.

2. Open Keychain in the utilities folder of your hard drive. Find the passwords that are stored for your particular network and delete them. There may be multiple passwords for your network, so search carefully.

3. Repair permissions using the disk utility.

4. Reboot the computer.

5. Reenter your network data to log into the network.

This worked fixing my two computers and my parent's computer. All have been working well for a few weeks now thanks to this. I think the passwords somehow become corrupt with keychain because analyzing the logs of my AEBS, I could see that the computer was registering but the AEBS wasn't giving it access (I'm using WPA2 encryption).

Hi There,

I had the same issue as you, only I had a D-Link DGL-4500. It was initially set with the "Mixed 802.11g and 802.11n" mode, and I had the same problem as you and most others.

This is an AirPort issue with the MacBook Pro and the 802.11n wireless technology. Try setting your router to "802.11g Only" mode, and see if that works. It worked for me. As long as 802.11n is not broadcasting from the router, you should be able to get a stable and fast connection.

I know it defeats the purpose of an 802.11n router, but it's a temporary fix until Apple releases an update or something.

Hope this helps!

Hi there

I've been trying to fix this problem for months now.

It has to be something to do with the MBP as my girlfriend's win xp laptop connects to our wireless network and maintains its connection quite happily. This is an embarrassment to Apple's premium notebook.

Like many others, my connection drops although the wireless signal icon remains full. The MBP thinks it's still connected but will not load any web pages. I have to turn airport on and off to rectify this (until it happens again after about 10 minutes or so of inactivity).

I recently upgraded to Leopard, hoping that would fix this issue. NOPE. When I was tunning Tiger I tried a fix that I found on these forums which involved replacing a .kext file. This didn't work for me.

I only recently phoned apple support. They told me to remove the HD:Library/Preferences/SystemPreferences folder, which effectively reset my network settings. I thought this had fixed the issue, but later that day it happened again.

If you are having this problem my advice would be don't bother wasting your money phoning apple support. You'll just have to wait and keep your fingers crossed for a solution.

If anybody knows of a real solution to this problem, please let me know!

pmaccarone and mikeyrocks: thank you for responding.

pm: I've been putting off switching to g-only, but just did this morning and will report back on my results.

mr: Our little iBook works just fine; as in your case it's the MBP that's unhappy. I probably won't be upgrading to Leopard anytime soon.

The DIR-615 is my first wireless router (I'm an intentionally late-adopter to avoid problems such as the one we're discussing) and other than the MBP problem, I'm happy with the product and the comprehensive, browser-based configuration software. For $50 I think it was a good deal.

I am having similar network problems with my Macbook Pro. I'm pretty sure it is (gasp) a bug in Leopard because when I boot into Vista I haven't noticed this problem. Sometimes I can regain connectivity by turning airport on and off a few times. Other times it takes one or more restarts to start working again. This is a new problem. Seems like it started after Apple fixed the problem with the keyboard not working intermittently.

I'm connecting (most of the time) to an 802.11g only WPA home network.

This is my first Apple and every time I start to think I may stick with Apple, another bug crops up that prevents me from using my $2000 machine. Arrgh...

Using a WPN824 (Netgear RangeMax Wireless Router) and keep having problems with my wireless connection as well. I cannot find the root cause though as it happens sometimes, and sometimes does not. There is no special process or tool i run. It's just like dropping connection OR getting extremely slow (high latency - did anyone experience this as well?) just during and in the midst of normal operation. The Router is running in 54Mbit compatibility mode by the way just to avoid problems with proprietary speed settings.

To work around this i tend to switch to cable connection via the same router which works perfect then. I'm switching back to my wirless every other reboot or when i move the laptop .. until the WiFi connection gets bad again. Bad thing is at my second location there is no possibility to switch to cable so i have to cope with low latency WiFi every now or trying to fix it with some of the methods mentioned before (Airport Off/On, Reboot..)

I've called Mac support, because- like all of you- I too have issues with my wireless connectivity cutting out. I've noticed that as long as my system doesn't idle or go into sleep mode, the wireless connection seems alright. But if I walk away from my computer for 10 minutes or more- I generally have to re-start my computer. So, on to my support call...

THE GOOD NEWS: Apple already knows about this issue and their engineers are working on a solution.

THE BAD NEWS: Apple already knows about this issue and there is nothing you can do about it until their engineers figure out a solution.

I'm at my wit's end with this problem (the 1st birthday of my MacBook Pro is fast approaching), if they don't get it fixed within the next month, then I think it's well-withing my rights as a consumer to ask for a new computer with a wireless card that will work with the OS installed (by the way, I installed Leopard and constantly make sure I'm current with my updates- that didn't resolve the problem).

Just want to throw my hat (MBP) in the ring too. Have had my 2.2Ghz MBP since they were released and am having the exact same problems described here. I also have an iBook G4 800Mhz which NEVER drops or loses its' connection. Considering the iBook Airport is so good I tried Sharing the internet connection wirelessly from my iBook to my MBP (without router) and sadly continued to have the same dropout issues. As a control test I also tried this with my iBook and Mum and Dad's Mini and a friends iBook and all shared their internet directly - via wireless - to my iBook without a hitch... But my MBP continued to drop the connection (regardless of which machine it was wirelessly connected to) around the 9-10min mark. It's a most frustrating problem. For those whom are interested I tried sharing the internet connection with and without a password protected wireless connection. Didn't make a difference.

Oh, and this is all on top of the first letter often missing when I type. Blargh...

I'll throw one more "Me-to" into the mix, with a caveat - I sort of found a way around the problem.

I had a G4 powerbook, and an Aug' 07 MBP running Tiger, and a Buffalo blahblah 802.11G running DD-wrt v23sp2, using WPA personal, and for more than 2 years, it worked flawlessly. No wireless issues w/ the metal case of the PB or the MBP.

Then I upgraded to leopard, 10.5.0, then updated to 10.5.1. Now I frequently wake the MBP up from sleep, and it won't find my home wireless...tho it will find lots of other wireless networks...just not mine. Argh.

I've tried watching the "packets on the wire" so to speak. tcpdumping and using ethereal to watch wireless packet traffic - sure enough, the wireless is WORKING, but just not finding my wireless connection.

Maybe it has something to do with using WPA, vs a wide open network...I'm not willing to run an open access point, so I get to deal with the weirdness.

The solution that works for me 95% of the time:

1) Shut down all programs trying to do network stuff (Adium, firefox, mail, et al).

2) turn off wireless.

3) open up network pref pane. go to Airport -> Advanced

4) Delete my home network. Hit Ok. Hit apply.

5) Re-add the exact same network, same WPA password, tell it to remember. Hit Ok. Hit apply.

6) Turn on wireless again.

And my network appears almost all of the time. About 5% of the time, it doesn't work.

Hope this helps folks limp along until Apple comes along with a fix.

Good luck!

yup I too have been having this issue, my powerbook G4 experiencing no problems but my MacBook Pro's wifi playing up. I run a NETGEAR DG834 with AirPort Extreme (802.11g) base station.

It wasn't happening frequently enough to drive me totally insane until this week (i currently use my MacBook Pro primarily as a home music studio and my powerbook for email/internet/other work so i didn't actually need to be on the internet with my MacBook Pro very often anyway) . When I ran software update and installed the new itunes/front row/quicktime updates then restarted, it wouldn't connect to my home network at all! The network showed up in the list and kept asking for the password again (although its in my keychain already!), and despite entering the correct password it kept failing to connect. I don't know if this problem is actually connected to those updates, but I definitely wasn't having an issue like this before upgrading.

However, thanks to cerby, I have managed to connect and post here - hurrah. Deleting the network like you said and switching the airport back on brought back the connection instantly. Cheers!

Please apple hurry with a proper fix!

ah booger, although i'm connected to the internet now, the ruddy thing keeps cutting out on me! Its a painfully slow connection too, my powerbook is browsing at a much faster speed than my macbook pro.

I'll throw my hat into the ring here as another with these sorts of problems. I was blaming my wireless router (NetGear MR814v2) which is capable of 802.11b only. "Glad" to know I'm not the only one. My G4 Powerbook works fine, as does my G4 iMac, but the Mac Book Pro is having lots of problems maintaining wireless connectivity. Hope Apple gets it fixed up! As with others, I'm very disillusioned to be having these issues with my new, $2000 notebook! Sadly ironic that I have to break out the Powerbook if I want reliable wireless connectivity.
