MacBook Pro constantly losing wireless connectivity

I have a Macbook Pro from early 2011 and had experienced this problem without knowing it was a Apple issue and blaming it on the network, routers, etc. Changed several routers without solving the problem. A couple of days ago I bought a new large display and a bluetooth Magic Mouse and Keyboard. Since I connected those devices my internet connection went bananas!!! I can't use those devices and be connected to the internet. I turned bluetooth off and the problem disappeared. I can't believe Apple has had this issue around for this long and haven't come out with a definite solution. Very disappointing.

Andrew, I'm very happy to hear this helped you - I know what you have been going through - I was also ready to toss away the MBP.

This is really annoying, no real solution since years!

I really read through the hole thread because for a such an expensive piece of hardware its really disappointing.

Long story short, MBP late 2011 having occasional wifi problems. Connection loss with strong wifi signal and while still connected. But whats sligthly different to 99% of the posted problems here is. I´m having theses discs not permanentely. I can run my MBP 2 weeks without any issue, and the next day (nothing changed in MBP and router) it disconnects every few seconds. while having the same as the most: only MBP is affected no other wifi device. We shortly moved and live in a new flat (total change of wifi surroundings). After 2 weeks the problem occured again.

BUT I have the same problems in WIN 7 @ bootcamp. So this can´t be of any problem of the OS(X). WIN 7 is showing an exclamation mark with full wifi signal strength. Disabling and reenabling the wifi works for a short period of time. What sometimes helps for a longer period is rebooting and restarting the router.

So for my problem is the conclusion:

- not any OS problem

- has to be the hardware of the MBP or any combination of router+hardware

- some external trigger has to be the source (otherwise why can I operate over 2 weeks flawlessly and having problems the next day without changing anything?)

- didn´t had the chance to test any other router hardware

I will oberserve the problem and try wifi setting in the router (channel and band), because this is the only explenation that makes sense. And I think a special combination of router channel and external interference IS THE SOURCE!

Anyone?

Add me to this unfortunate list!

OS X 10.9.4

2.6 Ghz Intel Core i5

MBP 13"

I have this similar problem, I can connect to a public wifi, but not my home one. My wife is able to connect as well as my phone with no issue, my computer is the only one that can't. I have retried resetting the router, modem and the the connection my computer has.

Hello everyone. I too have been suffering from some oddities revolving around the airport. I have a 2009 Macbook. My wifi drops out soon after booting up and refuses to reconnect and only does so when I restart the computer. What is most odd is the signal bar is completely full but when I go to network preferences it appears that the wifi is off. I just upgraded from snow leopard to mavericks these problems surfaced. As an added issue, sometimes the signal bar is greyed out and show only an X indicating that I have no software. I have tried many of the solutions that others have suggested to no avail.

Any ideas other than going back to the two cans and a piece of string solution?

Hi all... I am on page 136, and I don't know if I have a solution that has already been said... so please forgive me for not checking.

I have been seeing with my newer MBP an inconsistency when connecting to specific WiFi access points. Some I have used for years fail me but other machines succeed where I could not. New access points as well would fail for this machine where other machines show no problems. I tried turning off bluetooth. I tried turning off wireless. I restarted the machine. I triple checked software updates. The problem was a mystery.

So I tried the following, and I have not had WiFi issues since.

1) Enter System Preferences (Click the apple and select System Preferences)

2) Enter Network Settings (Click the round Network icon)

3) Remove the existing WiFi setup (Select Wi-Fi in the left hand list of network options available, and click the " - " at the bottom of the list)

4) Apply changes for good measure. (This may have been an extra step, but just to be sure, apply none the less)

5) Click the " + " and add in a new Wi-Fi connection.

I don't know why, but my new wifi connection works as I expected it should. I am guessing that stored connections, or some setting stored in my old wifi setup was corrupted. I have been seeing months of frustrating wireless failures. I have been 24 hours problem free now. I hope this helps anyone else with the same issue. Sorry to others who have a different one that this can't fix.

Cheers.

Like the previous poster, I am on page 136 and apologize if I am suggesting something that has already come up. I had an incident with several MacBook Pros in one office (all running 10.9). I had installed a new wireless access point for the office, which is a mix of Macs and Windows-based laptops. The Windows machines all worked fine, but all of the Macs exhibited the behavior of dropping off of the network frequently. I noticed that the old access point was a b/g. The new one was a g/n. As an experiment, I unhooked the new AP (g/n) and put the old one (b/g) back in place. I did this as several of the MacBook users were in the office and complaining of not being able to stay on the network. Immediately every MacBook connected and none have experienced a single drop since. I submit this as another clue at the scene in hopes that it will help Apple figure out this issue.

WORKED LIKE A CHARM!!! THANKS SO MUCH!!!!!!

What worked?!

Amazing thread, Apple should address this properly.

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

http://forums.macrumors.com/showthread.php?t=518958

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).

Just curious to see if there was something new. This is an old many times posted "fix" that didn't work for me. That's the problem with these huge threads when someone posts and says "it worked!" and doesn't post what it was that worked. It could and has been a billion things.

The curious thing that has happened to me, is that I get WiFi after waking from sleep now. But once it's up, it's a toss up as to how long or how well it'll work. I can almost depend on WiFi returning after waking from sleep every time. Sometimes after start & restart. Now if it would only stay and work! I'm running 10.6.8, 10.9.5 and 10.10v2 and this behavior is consistent across all OS's. It's kinda like once you're "infected" it affects the machine as a whole no matter what OS. For me this started in Mountain Lion.

I have this problem too. I thought it was the modem or Apple router, paid for better internet service, and had service technicians come out to inspect modem and internect connectivity for them to tell me its my MacBook Air.

Hi,

Network fix Mac

Make DNS OPEN DNS - just lookup ip for opendns

In Keychain network logins - remove all network login - system will re-create new one.

Renew DHCP lease

Auto proxy discovery

I believe the most important part is in the Keychain part. Anyway, after these steps, mine has worked flawlessly until the next update and then I had to repeat it and then it works fine now.

This was brilliant advice! I just followed the first 2 steps, and all seems well now without even restarting my computer. I'm very grateful as my productivity was suffering greatly with this problem.
