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:

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.

Retina MacBook Pro Wifi Issues

Hey guys, I just got my rMBP today and the wifi is terrible on it. I have the 2.6, 16gb, 256gb ssd model with mountain lion. For some odd reason, when I'm at home my wifi connection constantly drops. I'm using a cisco WAP4410N AP, if that helps at all. I called apple but they weren't of much help. I also tested wifi at a relative's house, and, for some reason, it worked perfectly for the hour and half I used it. At home, even when I restart my modem, router, and ap, I can only get a max of 15 minutes before the connection drops. WiFi works perfectly on every single other device I have (Android phone, iPhones, tablet, other laptops), and I've tried switching wireless channels and broadcast type settings to no avail. I've deleted all the AirPort preference files (as the apple rep asked me to) and booted in recovery mode, and nothing occurred. I think of myself as being tech savvy, and I am confused as **** right now.
Any ideas?
Thanks,
Krad

Well, give this a shot:
1) Go to: http://www.cisco.com/cisco/software/release.html?mdfid=282414137&softwareid=2824 63166&release=2.0.5.3&relind=AVAILABLE&rellifecycle=&reltype=latest&i=rm
2) Download the 2.0.5.3 firmware
3) Open your access point's configuration page. I'm not sure what your gateway is, since I had to modify mine to match my network. The default should be 192.168.1.245, with the username as admin and password as admin. If you haven't changed any of the default settings, you'll have to connect through ethernet, as the AP doesn't allow you to configure over WiFi out of the box.
4) Click the administration tab, and you should see firmware upgrade under that.
5) Upload the new firmware file, and click upgrade. It takes a few minutes so just wait for the AP to restart on its own.
Hope this helps!

Macbook Pro Wifi Issues with WPA2 Enterprise key

I have a MBP 13" mid 2009 model. There is usually no problems connecting to home networks. It remembers the passwords and connected seamlessly. However, I have problems connecting to networks with WPA2 Enterprise settings. I had tried it in NYU and I am trying it at my current school too. It keeps forgetting the WPA2 key from time to time and although I have tried all ways to get it to remember the key it still fails. I have used other MBP from the same time frame and they seem to be working perfectly. Even my iPod touch works perfectly with these WPA2 enterprise networks. Can anyone suggest a workaround?

The networks do support WPA2. It works perfectly on windows 7 and other MBPs. There it doesn't keep asking the password and stores the password in keychain. But on my MBP it keeps asking me for the password from time to time

My Macbook PRO wifi freezes in some minutes.

My Macbook PRO wifi freezes in some minutes. I have to disable and enable again several times.

Start with these:
Troubleshooting Wi-Fi issues in OS X Lion and Mac OS X v10.6
If you have been using the same settings since forever, open
System Preferences > Network > Wifi > ( Assist me ) ...
... and use the Setup Assistant to set it up again from scratch, including a completely NEW "Location".
If yopu still have problems, downlaod iStumbler to look around at what other devices are around you, what channels they are using, and what the signal levels and noise levels of thi=ose devices versus your Router might be.

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.

Can't install windondows 8.1 on my macbook pro - format issue

Can't install windondows 8.1 on my macbook pro - format issue
Running latest version of Mavericks.
Followed the exact bootcamp proceduce.
Have official window 8.1 version on cd.
All goes well until I have to format the 65Gb partition. Disk=0 and partition=4
Can't get over it. Altough I formatted it via a hint found on the internet with "dislpart" in NTFS. Wich also went weel and give the labelname "BOOTCAMP". But still no luck.
I have two questions:
1/ How to start my mac again in normal mavericks mode?
2/ How can I overcome the windows installation issue?
Tried already a lot of hints found on the internet.

First, make a time machine backup. You will need to erase ands reformat your hard drive. I had the same issue. The issue is that you can't install Windows using bootcamp without having the hard drive formatted as Mac OS Extended (Journaled). Do this from disk utility or recovery mode (hold down command and r at startup). Then you have to restore the backup to the hard drive. Then make a usb installer drive with bootcamp and then partition and install. Here's a tip: after you install bootcamp and are in the Windows desktop, go into the installer drive and then go into the bootcamp or support folder, then find a installer that contains the Apple bootcamp drivers. Also, you will need to convert the disk to an iso file. TO MAKE THE USB DRIVE FROM A DISC, USE THIS LINK

Macbook pro shutdown issue

Macbook pro shutdown issue when I push the power button it immediately goes into sleep mode

Hello Marrio22,
Thank you for the question. With OS X Mavericks, the power button has new functionality:
OS X Mavericks updates the power button behavior on Mac computers.
Using the Power Button to Sleep & Wake
Tap the power button in Mavericks to put your Mac to sleep or to wake it up:
Tap the power button once to put your Mac to sleep.
Tap the power button again to wake your Mac.
Press the power button for less than a half a second to sleep or wake your Mac. This duration is similar to pressing the Space bar or Return key to wake your Mac. The power button works this way across all Macs using OS X Mavericks, including both notebook and desktop computers.
Accessing the Shut Down Dialog
Press and hold the power button for 1.5 seconds, to bring up additional options:
Forcing the Mac to Turn Off
Hold down the power button for 5 seconds to force the computer to turn off. Important: You may lose unsaved documents if you force the computer to turn off this way. Use this method of turning off your Mac only if it has become unresponsive for an extended period of time. Normally you should shut down the computer by selecting Shut Down from the Apple menu, or from the shut down dialog pictured above.

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 connectivity issues since updating to Mavericks

I upgraded to the Mavericks OSX 10.9.1 and started seeing WiFi issues. The issues seem to happen when I have to wake up the system after closing the lid. I have an Airport Extreme router

I have been having the same problem. When my MacBook Pro running 10.9.1 (Mavericks) wakes up from sleep, whether from shutting the lid or inactivity, the Wi-Fi seaches for a network, but won't reconnect to my known home Wi-Fi network. When I try to select my network from the menu at the top-right of the screen, I get an error message after about 10 seconds saying that the network is unavailable. If I turn off Wi-Fi and turn it back on twice, I can then reconnect to my home Wi-Fi network. This is a very annoying problem. Please fix it in 10.9.2.

Macbook Pro WiFi connectivity issues

Hi there - planning on contacting Apple directly tomorrow but thought I'd put this question to the community before I run up my phone bill!
For the past few days I've seen my WiFi connectivity go severely downhill, I've had my new Macbook Pro 2012 (non-retina) for a little less than a week, and I haven't had a problem with my internet since a few days ago.
This is DEFINITELY an issue with my computer. I have other computers and an iPhone which work perfectly well with the same network - in fact, my girlfriend was next to me running on her laptop for 20 minutes whilst I sat there pulling my hair out to the messages of "You are not connected to the Internet" and "Network timeout".
The computer was originally installed with OS X Lion, but I updated to Mountain Lion after 2-3 days. (Perhaps it's a problem with this? Is this an ongoing thing with the range or the OS?). I have tried reinstalling the OS X, a frustrating ordeal as I actually needed an internet connection to do this! This, however, doesn't seem to have done too much...
I've tried deleting all information about my network (in the advanced wifi tab, and in Keychain), and also tried entering the wrong password in when manually adding the network, I'd heard that works yet clearly not!...
I feel like I'm using a mobile phone with bad signal when I have to hold the pc in the air as if i'm looking for that "sweet spot" (strangely enough this usually works for a minute)
Any ideas? I feel like I've exhausted all means, I'm at the end of my tether!

Macbook Pro Retina issues with Wifi Speeds

I have one of the new Macbook Pro 15" Retina models and have been having issues with Wifi Speeds. Apple has replaced the computer but have the same issue with the new one. When doing a side-by-side comparison with older Macbook Pros and PC's I'm seeing around a 10 megabytes per second difference. Is anyone else experiencing the same issue?

So an update on what I've found. After testing two different MBP Retna's basically hourly for 4 weeks I found a few interesting things, but ultimately resolved my issue. The first thing I found consistently between both MBP Retina's both on my network and in the Apple store on their network was the first thunderbolt port closes to the screen is slower than if you try to use the LAN cable adapter on the second port. I saw about 10 GBps between the two ports. The second thing i found was these new MBP Retina's aren't really compatible with older Apple networking technology. I have a single band Airport Express and a single band Time Capsule. Using either router they only worked on the 2.4 5Ghz setting and even with that the speeds constantly fluxuated. Most times I got between 2 - 10 GBps. After hours of troubleshooting it was recommended to update either my Time Capsule or Airport Express to one of the newer dual bands, which I did. After purchasing and setting up a new dual band Airport Express and spliting the networks to have one band constantly on the 2.4 5Ghz setting and the other set to automatic both with differing network id's this solved my problem. I now consistently see download speeds of around 35GBps and upload around 6GBps. So connecting the dots and drawing logical conclusion, these new MBP Retinas are really only compatible with newer dual band Time Capsules or Airports. Even though my single band was also set to 2.4 5Ghz, the same as the dedicated network used now on my dual band Airport Express, this MBP Retina had issues maintaining WiFi speeds.

New Macbook Pro Wifi connection issues

I just bought a new Macbook Pro. When I try to connect to my wireless router I get a "Connection Timed out" message. It won't connect. In order to connect I have to go to Network Preferences and Select "Diagnostic". After following the steps I can type in my password. It says the password is "invalid" though I know it is correct and then it connects anyway.! I must go through this process everytime to log on. Very annoying. Any solutions?

After taking it in to the tech department, I gave up on them and opened it myself. Re-seated the connection from the Superdrive to the main board, and it works fine.

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
