Apple MacBook Pro dropping wireless connection

Hi,
We have many MacBook pros that are having a hard time staying connected on wireless.  Often times a user can be connected for only minutes at a time.  Our wireless environment consists of 1142s and 3502 series access points.  We use WPA2 Enterprise for authentication via ACS server 5.x.
The Windows 7 machines usually never have an issue.  Can someone please provide some insight.?
*we use Lion OSX on our Macs.

  • Macbook keeps dropping wireless connection

    Hi 
    this is my first post so be gentle with me LOL
    I have had many issues with BT over the last 8 months, mostly due to the speed I had in my area (was 0.45MB when wired at one point), but I recently started to have an issue with the laptops in the house.
    I have 2 teenagers and luckily for them we all have Macbooks as I have given them my old ones when I have upgraded I am using a macbook pro (less than a year old & wireless N) and my eldest boy is using a Macbook (about 6 years old with wireless G) you might see where I'm going here....
    the problem is the older macbook keeps losing connection on the wireless, I have called and spoken to the 1st line support guys in India but it's a bit of luck if you can understand them let alone find someone who knows what they are doing. As I work in IT I completely understand and normally ask them to read my notes before advising me especially as I had so many issues last year when I was given a number to get through to the priority care team LOL , so far I have tried the following:
    moving the Hub 3 to several locations around the house
    reinstalling snow leopard 
    using a wireless dongle 
    I live in the middle of nowhere so there are no other houses around which have a hub3 sp none can be affecting me and I've checked this by using programs like inSIDDer.
    Finally I thought I'd take it to work to see if I could get the model number of the wireless card and order a new one and guess what it works fine!! So I thought I'd check at a friends and again it works fine for the whole time I'm there.
    Brought it home and it won't stay connected GRRRAAA!!!!!!! 
    I've heard that the hub3 doesn't like having a wireless N & and wireless G laptops on the connecting at the same time is this correct? Has anyone else heard of this?
    finnally I do have windows machines in the house and none of them  (2 laptops and a desktop which is wired) are having an issue but the Sony TV which is wired directly in to the hub will also drop connection randomly between 8 PM and 10 PM every day so I'm leaning towards the hub being a rubbish router instead of the problem lying with my Macbook

  • MacBook Pro's wireless connectivity with ZTE 531 ADSL modem using BSNL broadband

    I have tried to connect macbook pro with BSNL broadband internet connection using ZTE 531 ADSL modem. The connection using both wireless mode and ethernet mode failed repeatedly. Using the same modem, I am able to connect to internet through my Sony Viao running Windows 8 and HP630 running ubuntu (both in wireless mode and ethernet mode). I have tried the 'assist me->diagnostics' option in Macbook's network diagnostics. The first 4 indicators are green, but the remaining 2 (ISP and server) remains yellow. Repeated attempts were made by restarting the modem.
    Surprisingly, the Macbook works fine with a newly purchased Dlink N150 ADSL2 modem.  I have used the same WIFI settings ( as in the ZTE modem) in Dlink modem also. What could be the reason for this ?

    Hello jayan_a_r,
    From what you are talking about, it seems like you have done some good troubleshooting to attempt to sort it out. Try using a different Network Location as sometimes that could be an issue when trying to access the internet. Also make sure that modem is using the recommended settings for the wireless access.

  • Lexar USB plugged into Macbook Pro stops wireless connection from working

    Just purchased a Macbook Pro recently.  Noticed today that when a USB stick was plugged in (Lexar 32 GB USB 3.0) was plugged in, the wireless networking could not connect to any network services. 
    Finder kept trying to get to the network storage and failing or timing out.  Time Machine failed to reach the server.
    Unplugging the USB stick fixed the problem.
    Anyone seen this before?

    Thanks again for your help Rod!
    One of the first things I tried was different combinations of devices to see if it may have been the device just not powering up. The main device I use is an official Apple wired keyboard, because at home I connect my MBP to my monitor and use a separate keyboard and mouse. I have tried other devices too with the same result, they only work when the dock is connected. I have tried connecting my iPhone via USB cable, i have a 16GB SanDisk Cruzer flash drive, which only lights up if the dock is connected, and I have a 4 port USB hub with a power LED on it, which again only lights up when the dock is connected.
    I looked in system profiler, and it says the USB ports are there, but doesn't recognise any devices plugged in, other than the dock. However, when the dock is plugged in, for example, it recognises the Apple keyboard in the other port.
    I took two screen shots, one of system profiler without the dock plugged in (USB keyboard still plugged in but not showing up), and another of when I plugged the dock in.
    Without Dock:
    With Dock:
    It might be worth pointing out that the HDD dock has two USB ports on it, which is what is highlighted in the second pic.
    I have also tried rebooting the computer with devices already attached but with the same result again. I've tried booting it with the dock and the keyboard attached, with just the keyboard, with just the dock, but either way unless the dock is connected, nothing else will work via USB.
    I just want to say thanks again Rod, it's very kind of you to spend your time trying to help me, and it is really appreciated!
    I'm going to contact Apple support shortly and see if they can offer a solution, or see if I can send it in for repair, which I am reluctant to do seeing as it's my only computer
    Cheers!

  • MacBook Pro Retina Wireless Connection problem

    I recently purchased a MacBook Pro Retina (late 2013) w AC wireless capability, and I have not been able to connect to my wireless network at work. Other computers, including my previous MacBook Pro (mid 2008) and my iPad 3 are able to connect to the work network without problems and I have no problems connecting my new MBP to my home or other networks. I have Windows 8 on a Boot Camp partition, and when my MBP is booted under windows, it still does not connect. My MBP is running OS X 10.9.4. My work wireless network uses a Linksys Wireless G Access Point model WAP54G v.2. Rebooting the router does not help. When my MBP tries to connect to the work wireless network, the status in Network Preferences says "Wi-Fi has the self-assigned IP address 169.254.216.147 and will not be able to connect to the Internet."  Any help or suggestions would be greatly appreciated.

    Hi Jackso,
    Welcome to the Apple Support Communities!
    For troubleshooting a self-assigned IP address, I would suggest reading over and using the following article as a reference and resource.
    Internet connection does not work with an IP address space of 169.254.xxx.xxx from ISP, router, or manual configuration

  • Mac Pro Drops Wireless Connection to Airport Extreme

    I have a Mac Pro and every time I leave the machine for several hours when I return the Airport signal strength indicator is blank and I have to re-choose my network name to get back on the network.
    As background, my Mac Pro is setup to never go to sleep as it is hosting some web sites, the only thing that sleeps is the display, so I don't think it is any kind of issue on wake from sleep . . . it just drops the signal at some point.
    Has anyone ever heard of this kind of issue? It has always been this way and I just moved my Mac Pro to a location in my house where a wired connection is no longer feasible so I really want to try and resolve it... THANKS
    Mac Pro   Mac OS X (10.4.9)  

    Slow connections, weak signal, dropped, lost signal after sleep...
    While Apple has a good "troubleshooting networking" the Mac Pro using Wireless has had more of its own. I would pick up a Netgear router, go wired.

  • How can I fix my MacBook Pro losing wireless connectivity with Epson Stylus NX625 printer.  It will work once and then I get an error saying the printer is not connected.

    I can connect to my Epson Stylus NX625 through my wireless network and print a page or two, but then the next time I go to print it says that the printer is not connected.  Any fixes?  I have tried deleting the printer and re-adding it to my MacBook Pro OS X version 10.9.4, but sometimes it doesn't even find it, and other times it says it is connected, but when I go to print it says not connected.  Very frustrated.  I have also installed the latest drivers, etc.
    What now?

    Your computer is going to run hot while playing CPU/GPU intensive games - it should heat up and the fans should be noticably loud. As to why it's 'crashing' - can you post a kernel panic log? You may have some third-party kexts that are causing the problems.

  • MacBook Pro dropping bluetooth connection with HP Officejet 100

    I've recently started developing problems with my MacBook Pro (OS X 10.7.4) maintaining a bluetooth connection with my HP Officejet 100 Mobile Printer.
    The problem I'm seeing is that when I send something to the printer, everything starts out okay, but then after about 10 seconds, the bluetooth icon in my status bar indicates that it is no longer connected.     The printer pauses for a minute or so and then spits out the half-printed page.
    Anybody else seeing this?   Any suggestions on how to fix?

    I have a similar issue, albeit a different bluetooth printer from yours.
    According to a review on CNET's website, the dropping of bluetooth connections seems to have been introduced in the 10.7.4 update and did not exist in the 10.7.3 version of the Mac OS X Lion software.

  • Time Machine Causes MacBook to Drop Wireless Connection

    The fix was to turn off Time Machine.

    This affects my computer no matter what network I am on. As soon as Time Machine starts the backup I lose the connection to the wireless router.

  • Orange Livebox & MacBook Pro Slow wireless connection

    Hello,
    Looks like we are a lot experiencing a slow or sporadic wireless connection.
    I have done all updates, the MBP finds the livebox and connect properly but I have a very slow connection.
    Lan connection is working fine and quick.
    Please could somebody help me, this is my first Mac, if there is any tips or tricks to get a normal wireless speed.
    Cheers.

    What kind of wireless router or access point are you using?
    Are you getting full signal?
    Is the wireless router or access point around anything with a lot of metal or..
    since you said that when you connect to your modem via ethernet then you could have a problem with your wireless infrastructure... if you have tested your wireless network with another computer and it works fine or if you went somewhere that has a hot spot then you can determine if there is an issue with your home network or an issue with the wireless card in the laptop...

  • Can not get MacBook Pro to wirelessly connect to Deskjet 2512

    I have installed the software 3 times and I still can not connect to the printer wirelessly. The directions for converting from USB to wireless instruct to go to Finder/Applications/HP then choose my printer. The file only containsDevice Utilities, HP Scan, HP Uninstaller and HP Utility so I can go no further with the instructions. I installed the drivers again just to make sure that I hadn't missed something. Still no connection. Help. I have two of these printers and need them both connected.
    Thanks

    Hi sbritt,
    The Deskjet 2512 does not supports wireless printing.  You will need to either connect directly to your computer with the USB, or purchase a wireless print server.

  • 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.

    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?

    How do i go about connecting my Apple MacBook Pro 13'3 to the interent with an "Huawei Mobile Broadband E367 HSPA+ USB ROTATOR" on the MTN Network

    If your USB port is working now, you didn't damage it and have nothing to worry about.
    The behavior you saw in your bus-powered Fujitsu drive is normal for a drive that needs more power than the USB port can provide.
    If your USB ports ever do shut down, resetting the SMC may bring them back online again quickly and easily.
