Strange macbook pro wifi problems - selective wifi disconnection

I have 3 macbook pros, two iphones and an apple TV. My primary macbook pro has some very unusual wifi problems that are hard to pin down. It frequently disconnects and reconnects itself to the internet constantly throughout the day. I've been testing it in various ways and today I noticed the strangest anomaly by far.
While working today, my primary macbook pro could not connect to the internet through any of the 3 browsers I use. Airport Utility said the internet was down (internet icon was amber, airport icon was green). However during this disconnection, my p2p application (Soulseek) experienced no disruption of service and continued to download files. I opened my second macbook pro and strangely enough, the 2nd mac was able to connect to the internet through browsers without issue, and the airport utility on the 2nd macbook pro said the internet was connected. My Apple TV was connected too as well as my iPhone.
It is often difficult for me to troubleshoot network problems because there are so many variables (ISP, airport assembly, airport base station, OSX, airport utility, modem) but I guess in this particular instance, it seems clear that the problem has something to do with my macbook pro.
My primary macbook has always had wifi problems (and honestly, my last macbook--the one that actually worked today!--had similar issues back when it was my primary laptop). Last week, my primary macbook pro had the topcase, display and logic board replaced by Apple. When it came back, it had the same wifi connectivity issues it always had. Often, a restart will be a very temporary fix, but not always.
I am at a complete loss for what could be causing these lapses in service. In fact, right now as I was trying to access these forums, I could not even get my primary macbook to open the Apple Support Site on any browser. Every other website would open, except Apple Support. I opened my 2nd laptop and it opened Apple Support just fine. After 15 minutes, my primary laptop finally opened up an Apple support page in Firefox.
It is really hard to diagnose the problem. I find that Airport Utility has been so pared down and streamlined to the point that it is worthless. It is basically a blank window with 2 application logos inside. It looks very simple and user friendly until it has a problem, and then it tells me to do something very technical without an explanation for the layman (such as assigning DNS servers or putting the airport in Bridge mode). I always follow Airport Utility's advice, but I still have odd problems. I am often confused as to whether I should use Airport Utility or the Network button in System Preferences. They have the same options, but they're arranged under tabs with different titles.
Anyway, does anyone recognize these macbook pro wifi connectivity problems? Constant wifi disconnection on one machine (while all others experience no connection problems) coupled with instances of selective disconnection (like browsers not connecting while p2p is able to connect or browser connecting to some sites but not all?)
Thanks for any help or guidance

Same exact issue here. It happened once when I updated to Mavericks 10.9.2. It just happened again last night and I can't seem to fix it.
I tried all sorts of things like deleting the SystemConfiguration folder, PRAM, SMC, DNS flush, etc. Nothing helped. As I recall, the last time it happened it mysteriously fixed itself after a day or two.
Very weird problem. I have been troubleshooting computers my whole life but this one is tough to figure out. Other machines in the house connect up just fine.

Macbook Pro Wifi Issue

I incorrectly posted this in the wrong thread this morning.
I'm hopeful you might be able to help me diagnose a problem I'm having. I'll provide as much detail as possible.
I have a first generation MacBook Pro. As of this morning I was running 10.5.6 and up until this week was using a linksys router and a comcast cable modem.
I used to have a great wifi signal throughout the house (always full strength), and around 12-18 months ago noticed the signal would weaken. The best I would get would be minus the top bar on the signal, and usually only if I was directly above or next to the room with the router. There were no new phones or devices added that might adjust the signal. On the other side of the house, I would have no signal at all.
My wife has a nine year old ibook and has no issues connecting through wifi.
When I bring my laptop to her parents' house or to the Apple store, where they use Belkin on N or Airport Extreme, I get a full signal.
I've recently suffered a hard drive failure and had a replacement drive installed. The problem persists despite the software update.
Not knowing if it was a router issue or an airport card issue or a combination thereof, I went to the Genius Bar. The genius recommended I upgrade my router to Airport Extreme, and if that doesn't work to return it and he'd focus on the airport card or antenna. I could get the flat rate repair (no AppleCare at this point) for $320+ to repair the problem if Extreme didn't work.
I installed the Airport Extreme router and got a full signal in the basement, far side of the house, upstairs - everywhere. Until around 10pm. The signal died from the basement. If I walked into the room with the Airport Extreme router, I'd get a full signal. If I left the room, I'd get a partial signal. If I walked any distance (10-12 feet), the signal would die. I restarted both the modem and router with no change. I reinstalled the linksys router and got a depreciated connection. I restarted the Airport Extreme again and got a full signal throughout the night, morning, through restarts, and when I returned home from work.
Last evening after using youtube extensively it died again. Linksys would barely work if I switched back, and no matter how many times I restarted I couldn't get the signal to last outside of the area of the router. I left it in the basement overnight shut down, restarted this morning, and had a full signal.
I'm looking for any potential guesses as to what may be causing the problem. I don't want to replace the card if it's the antenna or sink too much cash into a machine if it's a heat related issue linked to Generation 1 syndrome.
During all of this the ten year old ibook works fine. I know a lot of macbook pros have issues with their wireless and don't want to sink in the cash if it's more complex than that. Any advice is much appreciated!

Hi nashie1002,
If you are having issues connecting to your WPA2 WiFi network after a recent update, you may find the troubleshooting steps and settings in the following articles helpful:
Wi-Fi: How to troubleshoot Wi-Fi connectivity

Apple Support: About Wireless Diagnostics
http://support.apple.com/kb/HT5606

It may also be worth doing a search for the specific model number of your router to see if anyone has noted any issues with Mavericks.

My Mid 2010 MacBook Pro wifi keeps disconnecting, and doesn't turn back on. Help.

*Mountain Lion 10.8.2*
Here's what's happening:
I'll be browsing the internet probably surfing reddit (because what else do college kids do right?) and I'll click one of the links I'm interested in:
The page won't load at all, as if I have NO internet connection.
Click the wifi icon in the status bar. Before several networks (not just my current network) would show up. Now ONLY the network I'm currently connected to shows up.
Turn off the wifi to try to "refresh" it.
Turn Wifi back on. Now it will say "Searching for network" and show that I'm connected to a network, but the bars never fill the status bar icon. If I go to System Preferences > Network and try to turn on the wifi there it lets me click the button, but nothing happens.
Get frustrated that the wifi WILL NOT TURN BACK ON and restart computer
Start browsing the internet again or doing whatever college students do on the internet until it disconnects again.
See 1
What I've done to try to aleviate this:
Made a genius bar apointment. I'm out of warrenty, but he did confirm for me that my wifi card is working as expected, and it's not a hardware issue, but more than probable a software issue. He did some cool trick where he went to Library>Preferences>System Configurations and deleted the entire contents (I think this is where the network information is stored according to some of the plists I looked through) then restarted the machine and everything seemed to work ok for a while, but the problem came back. I actually still do this sometimes when it happens but results seem to be the same every time (Plus I have to re enter network information when I do this).
Genius bar guy suggested that I try reinstalling Mountain Lion. Didn't want to get rid of my data, so I just did an install over my current build. This took some time, but it seemed to work for a while, but alas the problem came back.
Genius bar guy suggested (as a last resort) a fresh install. So That's what I did. I backed up my computer (Really I just coppied my documents folder and music folder to an external. I did not use a time machine back up because "ain't nobody got time for dat") and I then formatted my hard drive (Which is an SSD if that may have anything to do with anything), and installed mountain lion again. For a while things seemed good, but the problem came back.
For clarification:
It has happened on multiple networks, not just the same network.
On top of that, every time it happens I have other devices connected to the same network and they work fine.
It has not always happened, this recently started about 2 weeks ago.
I have not recently installed any software that could have possibley done this (I use mostly MAS store stuff with the exception of Bartender, TotalFinder, and xQuarts, but all 3 of those had long been installed before I had to format my machine)
I can't really force the problem, but it seems to happen sometimes after the machine falls asleep, but I know for a fact it's also happened mid use (as described above)
Can anyone give me any kind of clue as to what is happening, why, and how I can fix it?

Years of fine internet use via WIFI then randomly it starts dropping then one day (weeks later) it is no longer accessible at all and even saying "No hardware installed" when I click on WIFI icon at the top right on screen. Here is how I finally fixed it!:
For six months I wallowed in this problem and had to connect my macbook pro to the internet via ethernet cable which as you can image was very restrictive :/
I have had numerous laptop technicans befuddled by this WIFI problem and most concluding with how my WIFI card must be broken and that I will need to buy a new one. The last suggestion I had on the matter was to buy a USB wifi dongle.
So I ended up buying this one, http://www.asus.com/nz/Networking/USBN10_NANO/Unfortunately my macbook pro didn't want to read the install disc and it didn't autorun so it didn't work. After reading more forums I saw that you could download the program from the net and sure enough it worked.. BUT STRANGER when I took the USB dongle out the WIFI was still working!! The program appears to have reminded my four year old macbook pro that it is indeed WIFI capable.
So to find this miraculous program its located herehttp://www.asus.com/nz/Networking/USBN10_NANO/HelpDesk_Download/
Same link as above just under SUPPORT>Driver&Tools
You then click on a file when its downloaded and a file called MAC will appear, then click on install. Within 5 minutes you should have your WIFI back. My macbook pro crashed again today but without having to get the shortest ethernet cable you've ever seen out again - I was able to install the program again and WIFI was up and running once more. Moral of the story - didn't need to spend any money to fix this and not even using the USB dongle.
So happy!! Hope it works for you too!
This also worked on a MacBook that lost its WIFI when a user accounts password was changed and the keychain password wasn't known to them - another random way to lose WIFI apparently

Macbook Pro - WiFi turns OFF and won't turn back ON

Hello,
this is my first time posting something on this forum; I will be as detailed as possible. I bought a Macbook Pro back in 2011 and It came with Lion OS. Last year I upgraded it to Mavericks and so far it has been a nice experience. However, in the past week I have experienced a very strange and irrating problem with my macbook. While doing work all of the sudden the WiFi would turn off and lose all connection to the web. I attempted to turn it back ON by clicking on the wifi signal icon but something weird occured, it was still 'ON' according to my mac and the only option available was to actually turn it OFF, so i clicked on it and the icon would go empty with no curvy lines (i attached a picture). Then i clicked again on the icon to turn it back on, however, as was doomed to remain in this state cause no matter what I tried.. the wifi will remain off even after clicking on the 'turn wifi on' option multiple times. I tried going to the assist me option under network preferences and I obtained multiple results with no fix. I tried sending my mac to sleep though at first seemed to fix the problem.. the wifi inmediately went back to being off and wont catch a signal. The only thing that fixes this is a fresh restart which is annoying and unacceptable...this is really annoying and I need a solution asap because this problem is become very frequent (once every 2 hours)... any help will be appreciated it.
I attached 2 pictures and the console log when this happened.
1. A picture of my assist me window before i sent it to sleep, shows the WiFi on the left with the 'Failed' (which confuses me). it also shows the wifi icon empty ( like it was off) but the computer shows as if it was on and would ask you to turn it off... weird?
A second picture after I sent my mac to sleep. Though it seems like there was no wifi signal available, the router was on and literally next to my mac...but my machine wont catch up the signal. (other devices were connected to the wifi and have no problem with it).
Here is the console log right before and after my this problem occured:

Thank you for your detailed troubleshooting attempts. Very helpful. Sorry, I cannot read "logs." My eyes just glass over on those things. Hopefully, a knowledgeable user will come along shortly to decipher for you.
I noticed from the pics that your location setting is "untitled." Have you tried the "Automatic" setting? Run the diagnostic test? Results?
Try the basics first:
   Change your router channel number. Most times this works & is all you have to do.
Disconnect & reconnect your modem. unplug it for about 10 seconds. Plug it back in. Do the same for Apple’s routers. Wait for everything to reboot.
System Preferences>Network
Click the Assist Me button.
In the next window that pops up, click the Diagnostic button & do the necessary.

Macbook Pro WIFI connection slow and intermittent

I recently moved to a new apartment and had Time Warner install our internet/Wifi. My Macbook Pro will connect to the Wifi and work fine for about 30-60 seconds and then become extremely slow, even to the point of no connection most times. I have tried using both the new router and the old router that worked just fine at our old apartment but both behave the same way. I have reset the routers multiple times but that does not fix the situation and I do not believe the router is the problem since my two roommates (one of which uses a Macbook Pro) have no connection problem. My iPhone connects perfectly fine as well. When I am on other Wifi addresses, my Macbook works just fine. Also, my Macbook is only one month old. I called Apple to try and solve the problem and they believe it is an interference problem however the connection remains the same no matter how close or far from the router I am and all other devices don't seem to have interference problems. Any help is very much appreciated!

Might be corrupted network preferences ..
Type or copy paste the following:
/Library/Preferences/SystemConfiguration
Click Go then move all the files in the SystemConfiguration folder to the Trash.
See if that makes a difference.
Your Mac will generate a new SystemConfiguration folder for you.
If that doesn't help, try Wi-Fi diagnostics here > Wi-Fi: How to troubleshoot Wi-Fi connectivity

New Macbook Pro Wifi Problem.

Hi everyone,
I just recently bought a macbook pro. The same night I bought it, I started to notice that I would get disconnected everytime I go to certain websites, download something, etc. I would then be disconnected for about 5-10 minutes and then the Wifi would start working again. Whenever I got disconnected, all other devices on the network did as well. ( There is one other laptop and 2 iPhones that use the wireless connection, but not always at the same time.)
The reason I am posting here, however, is because the wireless connection always worked fairly well before I purchased and began using the Macbook.
My router is a Netgear WGT624 v3. While connected to an ethernet cable, it works fine. But when I'm upstairs I get disconnected very frequently. I realize that there are multiple threads concerning people getting disconnected with Macbook Pro, so I wanted to ask if there was a possible solution.
I always have a good connection and signal when I am connected as well. Any help is greatly appreciated.

Firmware update did the trick it seems. I feel dumb, should have known , thanks for your help.

Macbook Pro wifi and application issues, everything slow

Hey guys,
So my macbook pro has been giving me a lot of issues lately. It doesn't appear to be one particular problem and it's spread out across applications. Here's my situation:
The wifi connection in my dorm room wont work all of a sudden. It's the schools wifi, so I can't mess with. But my roommate, who also has a macbook pro, is having no problems at all. So I think it's just my computer. It SAYS I'm connected to the internet and has full connection, but it doesn't go through.
Here's the weird thing... I CAN connect to any other wifi on campus just fine. And all ethernet ports work fine.
I'm also having trouble with a variety of applications. My Twitter app, mail wont load anything, Itunes store is slow or doesn't work, the App store wont open, Celtx.....
I think it's all programs that require some sort of internet connection to function. And it's really strange how all these applications still don't work right even when I DO have internet connection (through ethernet or other wifi).
Few notes: I've tried reseting the permissions, and I have 40GB free on my harddrive. It's been happening for a week now, and I've tried rebooting many times. I did a large software update right before it started happening, but I'm not sure if they are related.
What do you think? Is this something I can fix on my own? Or is something damaged on my computer?
HELP!

Alright, Gryphonator, looks like you're being hijacked. Try the following:
1) Go to this webpage and download the latest stable version of Opera (in case you don't know, it's a Web browser, and if you don't like it, you can ditch it whenever you want); save it to your Desktop
2) Reboot your Mac in Safe Mode by keeping the Shift key down on startup until you get the Apple grey backdrop AND a progress bar. Once this shows onscreen, you can lift your finger from the Shift key
3) Once in Safe Mode, you are not connected to the Internet (unplug your Ethernet cable before you do anything), and only the basic OS X kernel extensions are running, so try and install Opera on your regular user account
4) Plug your Ethernet cable and try to connect to the Internet (you should be able to)
5) Unplug the Ethernet cable, and reboot normally
6) Once your Mac is up and running, try browsing the Web with Opera
7) Let us know of your progress (or lack thereof...)
The point of installing/using Opera is that it doesn't yet exist on your system, so it can't have corrupt plist preferences files and the like. Installing it in Safe Mode will prevent whatever is playing with your Internet connection from wreaking havoc with install.
Finally, for all its flaws, Opera is probably the safest Web browser there is. I've never been hijacked once in all the years I've used it, even when using Windows as my primary OS (see, you CAN turn to the Dark Side of the Force and come back!)
Keep us posted!

Macbook pro wifi symbol greyed out and will not recognize networks

My Macbook Pro has had an issue since this past fall of having its wifi symbol greyed out with an "X". It also does not recognize wifi networks as in simply no networks show up. Talked to Apple last week and they said to upgrade to Yosemite, but I am still having this issue. Help?

Have you used DVDs that have different region codes? It may be that your DVD drive is locked for a region code different from what Netflix is programmed for.
Ciao.

Macbook pro wifi security won't let me connect to public/login networks

I recently purchased a new Macbook Pro retina switching from Windows to Mac. One very frustrating thing I have found is that I am unable to connect to public wifi spots such as AT&T in Barnes and Noble. I read that a security udpate requires that the mac "phone" an Ip address at apple.com to inquire about the hotspot certificate in order to determine its legitimacy. The problem is I can't gain network access until I agree to the login/authentication page for the public network. Does anyone know a work around/way to connect to these public wifi spots? I get that security is important but it is very annoying not to be able to use wifi in places like Barnes and Nobles and Starbucks.

Macbook Pro Wifi Keeps Disconnecting

Ever since I got my new BELL Router, I've been having these constant WIFI disconnects. It would stay on for about 30 minutes and disconnect by itself.. anyone have any solutions to this problem?

Since it started when you replaced your router that sounds like a router problem.
Have you contacted your router manufacturer?

This is the Mac Pro desktop forum. I requested your post be moved to the MacBook Pro laptop forum.

Macbook pro wifi disconnects

I have a new macbook pro and use a dlink 2310 b/g router. Wifi drops out about twice per hour. If I go through network diagnosis it will reconnect. At the same time my new iPad in the same location does not disconnect.
Any suggestions?

Late 2013 15" Retina Macbook Pro - wifi connection timeout with one router

Hi,
I've recently purchased a new Macbook Pro retina 15 inch late 2013 model. Everything is fine at home, but at work I cannot connect to one wireless router (Netgear WAG102). The computer tries to connect but I get a connection timeout error after a few seconds for every attempt.
I have tried every suggestion for wifi issues that I can find on the forums, and have reset the router.
A colleague has also recently purchased the same computer except 13 inch model - he has exactly the same problem.
Any suggestions? I suspect given that two of us have the same problem that there is an incompatibility with the MBP and this particular router. I notice that there are quite a few discussions about similar issues with the macbook pro.

I too have a MBP Retina, 15", late 2013, and am having wifi connection issues. I've tried several fixes suggested on these discussions and by Apple. Nothing corrects the problem. I've been told it's my router, but I find that difficult to believe give that my wife has a MBP 13" 2012 (non retina), that has no issues at all, nor do our iPhones. It's just my MBP Retina.
My issue seems to be when waking from sleep, I lose the wifi connection. I have to turn wifi of then on again, and it reconnects. The only thing that corrects the problem for me is when I disable bluetooth. I have the magic mouse and it's basically useless becuase I need bluetooth on for it to work.
I find this to be an annoying problem. This is my first MacBook, and I really like it, but this wifi thing is bad. Never had this problem with my Windows machines.
