MacBook Pro and Leopard knock out my wireless network

I am new to Mac, just having purchased the MacBook Pro with Leopard 10.5.1. installed. I have a Netgear WPN824 router that works perfectly with windows based computers. I use WEP 64 bit security. The MacBook connected with no problem and surfs the web fine until I try to download certain files on the MacBook (such as the HP drivers for my all in one printer) or try certain video feeds online , such as a cnn video. The download not only stops midstream but actually knocks out my entire network causing me to have to unplug my cable modem and router and restart everything. This is a real problem. Does anyone have a clue why this is happening? I can download the same files on a Windows laptop with no problem. Help.

Hmm. It might not be the MBP. Are you using Safari? I've noticed that Safari at times is incompatible with many websites. Try downloading Firefox and try the same downloads.

    If both your MacBook Pro and iPod are unable to "see" the Wi-Fi network provided by the AirPort Express, it is most likely NOT that you are missing an "airport card," but the Express may be the issue instead.
    One quick test is to see if either device can "see" other Wi-Fi networks. If they can, then you can definately rule both of them out as the issue.
    By default, the AirPort Express will broadcast an unsecured Wi-Fi network with a network name of something like: Apple Network NNNNNN. Can either device see this network? If not, then I would recommend that you perform a "factory default" reset on the Express, and then, check again.

  • MacBook Pro will not connect to Cisco Wireless Network

    I have just bought a brand new MacBook Pro, running Leopard (OSX 10.5.1) and I just cannot get it to connect to the Wireless Network at my workplace.
    The MBP connects to wireless network and authenticates just fine, but will not obtain an IP address from the DHCP server.
    The wireless network consists of 16 Cisco Aironet 1200 Access Points controlled by a Cisco Wireless Network Controller. It does not broadcast its SSID and is WEP 128-bit hex protected.
    Changing the network from WEP to WPA is out of the question for me as this is under the control of my customers IT Department and they do not have any problems with their PCs connecting to the network. It appears to be an Apple issue.
    For reference, my old Vaio PC, my Nokia N95 and my iPod Touch ALL connect to the same wireless network without any problems whatsoever, first time, every time!
    If I boot into Windows XP from my Boot Camp partition, XP can connect wirelessly to the network without any problems, so it is not MacBook hardware related...
    It has to be a bug in Mac OSX... doesn't it?!?
    Things I have already tried (following suggestions on many forums):
    * Switching Airport off/on
    * Deleting various network-related Plist files and rebooting
    * Manually assigning an IP Address (not really permitted but doesn't work anyway!)
    * Disabling all network adaptors except Airport
    AP Grapher shows that the MBP is connected to the wireless network, at good strength, and packets are being sent and received, but Internet Access is not possible as no IP Address has been assigned. Instead, my MBP shows a 169.* IP Address (self-assigned). It should be a 10.1.255.* address.
    Can anybody please help? Thank you.

    i posted this same reply elsewhere because it worked for me for my Buffalo wireless router: try manually setting your IP address instead of relying on DHCP, which sometimes (I don't know why) doesn't work well with Macs. It's a good get around. I am a happy Mac user but nothing is perfect on earth, and when the Mac gives problems, it does give a lot of frustration. Macs are not as easy to troubleshoot as Win because a Mac is built to be user friendly(and it works most of the time), meaning a lot of the background computing stuff is hidden away from users to avoid user accidentally upsetting some settings.
    Unfortunately, the highly automated troubleshooting wizards provided by OS X are not perfect so when these software wizards fail to resolve the problem, like my Network Diagnostics, I have to spend more time tinkering around. There's "Terminal" of course but then most of us, especially PC converts to Macs, don't know how to use it.
    You should also try updating your MBP, see if there are any new updates being released.

  • MacBook Pro and Leopard updates

    I got a MacBook Pro in January with OS X 10.5 installed. Soon after I got it, I started having a variety of problems.
    --After sleeping, it would wake up but the screen would be turned off. Sometimes the screen would turn on if I pressed the power button. Sometimes it wouldn't, and I'd have to shut down by pressing and holding the power button.
    --If I plugged it in while sleeping, it would wake up, even if it was closed.
    --It unexpectedly went to sleep a couple times.
    --When I opened it after l sleeping, it sometimes would shut off rather than waking up.
    --The sound turned off completely--iTunes indicated that it was playing, but there was no sound.
    --It froze frequently.
    Other people have mentioned several other problems on MacBook Pros, especially with the keyboard, trackpad, and airport. See this thread: http://discussions.apple.com/thread.jspa?threadID=1432781&tstart=0
    I took it to an Apple store and they reset the power manager. That didn't solve the problems, so I went back. The second time he advised me to uninstall the 10.5.2 update, which came out in mid-February. Apparently there's something about this update that messes up the hardware on certain models of the MacBook Pro--specifically the 2.2 GHz models. I ran an "Archive and Install" (reinstalled Leopard from the install discs) and then didn't install the 10.5.2 update. I did that a week ago and haven't had any problems since.
    My only problem now is that OS X 10.5 is not as good as 10.5.2. 10.5.2 fixes some of the annoying features of 10.5, like the translucent menu bar. Does anyone know when Apple will release a new Leopard update that doesn't cause these problems?

    I have an MBP 2.2 purchased earlier last year and have applied updates since. I've had none of the problems others refer to. So to your problems.
    1) Always run Disk Utility after an update and do the Repair permissions. If the window indicates that some permissions have been repaired rerun the program until it's all clear. Some advise to repair permissions both before and after an update.
    2) To upgrade to 10.5.2 download the combo update for your machine from Apple/Support/Downloads. This is more reliable than Software Upgrade for your situation. Again do a Repair permissions after the restart(s). Don't interrupt the restart process. I think in this case there is a double restart before the machine completes the update.
    3) After all this run Software Update to see how many more updates are required. Probably these can be done through SU. Again repair permissions after.
    4) Check your Energy Saver preferences in System Preferences to either set them to default values or as you want them. If at some time these were changed this could explain some of the unexpected behaviours.
    There are all sorts of issues arise for different people but I have found Apple products to be very reliable since I bought my first Mac in 1984. Perfect - no.

  • ProjectMix with Logic 8.01, Macbook Pro, and Leopard.

    The subject line gives my set up. It is pretty hopeless to get this to work. I have a few questions that I would love to have answered.
    1. When I hook up the ProjectMix to my Macbook Pro, it is hooked up via the firewire connection. Do I need to also hook up midi cables? I thought the ProjectMix would work with just firewire between the mixer and the computer but when I read the section of the manual about control surface hookup, it seemed to suggest that I needed to hook up bidirectional midi cables.
    2. I realize that part of my problem may be that M-Audio has not released drivers for Leopard yet. But there seem to be a few posts on this forum that the latest 10.4 drivers work with Leopard. Is there any consensus on this matter?
    3. Most troubling is the fact that when I hook up a firewire 800 external drive to my MacBook Pro, the computer locks up when I try to access the drive while running Logic Pro with the Project Mix hooked up. I searched the M-Audio web site for any possible FAQs about this and found one that said, in effect, hooking up the ProjectMix and an external firewire 800 drive to a computer may cause conflicts and create distortion and drop outs because both ports are accessing the same port within the computer. Their solution was to get a PCMIA firewire interface card for the computer and hook the ProjectMix to that. No dice with the MacBook Pro since it doesn't have a PCMIA slot. Holy mackarel! Has anyone managed to use a MacBook Pro, the ProjectMix and an external firewire 800 drive either under Tiger or Leopard system software? Should I be looking for a different interface?
    I realize this is quite a ball of wax but any help would be appreciated. I hate to think that my ProjectMix has become a doorstop since I tried to change over from ProTools to Logic. After all, the ProjecMix has a setup specific to Logic that I set when I booth up the ProjectMix.

    I cannot really comment on this except to say that other posts on the websites I mentioned on my previous post show that you are not alone. I have successfully run a Focusrite LiquidMix on one FW400 port and the ProjectMix on the other FW400 port on my iMac. At the time I built my external drives (from my own choice of case, interface and hard disk) I opted to go USB2, partly because of concerns about FW audio and FW disks not being compatible and partly because I wanted to put two drives in each case, one of which was for use on Windows machines. Windows is cr*p at handling FW drives, so USB2 was essential for me.
    EDIT: maybe, just maybe you could either change the interface in your external drive case OR if you are really lucky maybe someone somewhere sells USB2 to FW adapters so you could plug your FW drive into a USB2 port. I can't say I've ever seen one, but you never know....

  • 2010 Macbook Pros and Leopard 10.5

    I've recently found out the hard way that you cannot run Leopard 10.5 on a new Macbook Pro (2010 models). I sold off my old MBP (17" - 2006 model - Core Duo 2.16) and recently purchased a brand new MBP 17" Intel Core i7. I tried installing 10.5 on the internal hard drive. I tried booting from external hard drive with the 10.5 OS installed. Yesterday, I confirmed (after calling Apple Support) that the new 2010 MBP models will not run any old version of OSX - they will only run 10.6.4 and higher.
    The reason why I would like to be running Leopard 10.5: so I can use some ExpressCard/34 adaptors I have - namely, the Duel Adaptor (a Panasonic P2 card reader). It is quite frustrating to find that the tools I've been using in my video work flow for years have come to a complete halt because I bought a brand new computer - a brand new computer with the same ports and connectivity as my previous computer... but with a newer, incompetent OS.
    My questions:
    Is there a list of ExpressCard/34 devices that DO work on the 2010 MBP's with Snow Leopard 10.6.4 (even if you have to download the drivers)?
    Is there a version of Leopard 10.5 that has been reprogrammed to work on the 2010 Macbook Pros with the Intel Core i5 and i7 processors?

    Murat Lahur - Thanks for the research. That's all I could find as well.
    rkaufmann87 - Thank you. I've heard rumors of hacked and/or manipulated versions of OSX, however, I've never seen one.
    OrangeMarlin - Incompetent only in the sense that the Apple motto we love, "plug and play on a mac", seems untrue with so many drivers dropped, unsupported or unavailable for Snow Leopard. I have all the available drivers for P2 installed. I can read P2 cards by plugging the camera into the computer via firewire. However, plugging the camera into the computer to download footage means that the camera is tied to the computer. It was wonderful having a ExpressCard P2 card reader that downloaded the cards faster than firewire and kept the camera free for shooting on busy days.
    As far as my research has shown, there is no 54 to 34 ExpressCard adapter that works with Snow Leopard. Therefore, Snow Leopard has seriously slowed my work flow and left me with useless devices.

  • Imac and Macbook Pro suddenly stopped connecting to my wireless network

    I am having the strangest problem. I've had a linksys router for years and my network has worked fine. I have a 2008 iMac, a new Mac Book Pro, Xbox 360, and a PS3 connected to it. Yesterday, the Apple products stopped connecting to the linksys, however the Xbox and PS3 connected fine. I thought it was my router being the problem so I went to Apple Store and bought an airport express to just set that up as my primary router. I could not set it up the normal way wirelessly as neither my iMac or MBP would pick it up via the Airport Utility tool. I had to hardwire it to my iMac to get it set up. It seemed to not be working however the green light did eventually come on. My xbox connected to it fine, however the iMac and MBP would not connect. Both did end up connecting but only for a short time and now neither can find the Airport Express. Does anyone have any suggestions as to what my problem is? It just doesnt make sense that both mac computers stopped picking up the linksys at the same time, and neither will really pick up the Airport express either. I'm just so distraught over this because I had everything working fine such as sharing files, wireless printer, Apple TV, etc.

    Hi there, I have exactly the same problem, one year with imac and a few months ago my wireless network disconnected and kept disconnecting and connecting on and off, it's not the Internet because laptop and other aps are ok
    Today I tried contacting Virginmedia to see if they could help and they told they are not trained for mac! Anyway they suggested to try to use the "renew DHCP lease" button in the TCP/IP page in network settings and it seems it is working better now, lets see if it lasts...

  • MacBook Pro only can't find home wireless network

    Hey guys!
    I purchased a 15" retina MacBook Pro by July. It brought Mac OS X Lion with it: I had no problems.
    However, more than a month later I upgraded to Mountain Lion, and I started to have the same problem ALWAYS: sometimes I would be connected to my home wireless network, perfectly fine. However, after shutting down, sleeping, etc, whenever I would turn the Mac on again, it wouldn't find my home network wireless anymore, but it would find e.v.e.r.y and other network available. Also, my phone, iPad, and every other equipment, would find it and work perfectly. After several restarts and wake ups from sleeps, the Mac would eventually magically find it and stay connected for an unpredictable amount of times (sometimes it could find it continuously for some days after some sleeps, and sometimes it wouldn't be found again after some hours of it being found again (assuming the computer went to sleep)). But if I try any other of the available networks it connects with no issue!
    And I've been in this game constantly! I've tried (almost) all the Mountain Lion wifi-related posts in the Internet, but none seems to solve it.
    I have only found a few posts with my related issue, which I recall: the Mac won't find, ONLY, my home network, while any other equipment can, and it can magically find it occasionally, lasting its connection until the next sleep or shut down.
    Help would be really appreciated.
    Thank you,
    Juan

    Hum, good point, the problem may lay with the router compability. My sister, who has ML as original OS has been having the same problem of not finding only our home network, so it seems that the problem lies on Mountain Lion compatibility with the router. I just restarted the router several times and we both got internet at the same time. The question is, as always, how long will it last until it won't find it again.
    Now, focusing on the router.
    Here, in Portugal (as for the rest of the world I don't know), the Internet provider companeis offer their own modems. Not only that, as those modems are both: modems and routers ( http://imageshack.us/scaled/landing/149/ofibrasjaestaabombar.jpg ).
    After writting the above, and re-reading what you said, you lighted me up the idea of entering the modem domain (you know, that url you put and have access to every definiton of the router?)
    Well, the password "type" was selected to "WPA and WPA2". What I did was selecting "WPA2" only. So far it seems that it is working. I'll do some restart tests etc etc and I'll let you know! (Maybe the problem may persist, but I'll only know days from know as it may seem, for know, that it is solved.)
    I'll let you know, and thanks for the help so far, Sig!

  • MacBook Pro is shutting off my home wireless network

    I've been reading through some of the other MBP wi-fi issues but couldn't find anyone discussing what I'm dealing with so I wanted to put this out there. 
    I got a MBP earlier this week and, it seems like after powering down or shutting the MBP and reopening it, my wi-fi network at home shuts down or isn't recognized.  When this happens, I have to unplug my airport extreme and turn the internet on and off on my cable router so the wi-fi signal can be recognized on my wireless devices.  It's not just the MBP (running Lion 10.7.3) that can't find the wi-fi when this happens; my MacBook (running OSX 10.5.8), my TV with wi-fi and my wife's iPhone lose their signals also.  The airport extreme and my cable router still are showing that they're running when this happens (green light on airport).
    It only seems to happen when the MBP has been powered down or closed.  Not sure if it has something to do with the airport extreme router that's in the MBP.  It doesn't seem that anything is actually turning off the airport extreme but none of the devices can recognize the wi-fi signal after this happens.  Turning off and on the airport from either of the computers doesn't seem to do anything.  It requires a reboot to the airport.
    Any thoughts on this?

    linc davis - the MBP does connect to the wi-fi network.  I haven't had any issues yest with MBP automatically disconnecting from the wi-fi (as i've read other people have had). 
    I've really only noticed it as an issue when the MBP was shut down or closed.  in those times, it seems that the wi-fi network is being shut off for everything in my house (not just the MBP).  for example, i left my MBP on while i was out of the house.  it went to sleep but i didn't shut it so everything was fine when i woke it up to get online just now.

  • How can I connect my macbook pro to printers on my windows wireless network, How can I connect my macbook pro to printers on my windows wireless network

    My Macbook Pro running lion 10.7.2 is connected to my wifi network, which also has a PC, an hp photosmart and an hp laserjet connected to a server.
    I have been able to set up printing from my mac to the photosmart by entering the ip address, although it can be tempremental.

  • How to prevent a MacBook Pro from connecting to a certain Wireless Network

    I just got a new AEBS for christmas, and i have noticed after restarting it to apply new settings, my macbook will automatically connect to the 2.4ghz wireless G signal, instead of the 5ghz wireless N connection. I have tried removing the SSID from the preferred networks list, changing the password in my keychain, and even removing the info from the keychain, also i put the wireless N connection SSID name at the top of the preferred network list, and after trying all of this, my macbook, will still connect to the wireless G connection. Any Suggestions? Thanks Much!

    Welcome to the discussions!
    Your computer will automatically connect to the strongest signal. 5 GHz signals are absorbed by walls, ceilings and any obstructions far more quickly than 2.4 GHz signals and that may likely be causing the issue that you see there.
    Unless your computer is close to the AirPort Extreme (AEBS) and/or you have close to line-of-sight between your computer and the AEBS, the signal from the 2.4 GHz band at your location is probably stronger than the 5 GHz signal.
    You do want your computer to choose the best signal possible, correct?
    Or, are you asking if there is a way to force your computer to connect to the 5 GHz network, even if the 5 GHz signal quality is not as high?
    Please confirm if that is the case. You won't be able to try to force this connection unless you have assigned different network names to your "main" and "guest" networks. By default, they both have the same name. Have you made these changes by clicking Wireless Options in AirPort Utility?

  • I just upgraded to CC (from LR 5) on Macbook Pro and can no longer import to Network Drive.  New version is LR 5.7.  Help?

    Just like the title says: MBP, retina works great with LR 5 installed from CD.  Added CC, upgraded to LR 5.7 and now import "hangs" with no activity.  Have been using LR since version 2.
    More info: the problem is writing to my network drive (which has been working since LR 2...  It seems a Temporary Folder is created with permissions 755 (owner=rw, group=r, others=r),
    then nothing more.
    Has something changed with respect to LR handling of network drives.  This is a Linux CIFS/SMB share (again, been using since LR 2).  Catalog is local on my MBP.

    This is my post and I'm new, so I may not be providing the answer in the "usual" manner.  (Feel free to educate me!)
    Solution:
    The mounted volume on MacBook is /Volumes/photowork.  Notice the lowercase 'p' in photowork.   In LR I had selected a mount point
    with *uppercase* 'p'.  See screen shot.  Summary: The already-selected mount point was /Volumes/Photoshop.  LR had no complaints.  When
    I changed the mount point to /Volumes/photowork LR imported as expected. 
    This only became an issue since the upgrade, as I simply never tinkered with mount points and so on.  This archive
    server has files back to 2000 on it.    Thanks so much to those who responded.

  • MacBook Pro and Time Capsule after adding new wireless router

    I have a MacBook Pro and Time Capsule (which functions wirelessly to router and computer). I added a new wireless router (netgear, not my idea) and had to change name of wireless network. Now Time Capsule flashes amber and does not show up in Airport Utility.
    Do I have to set up Time Capsule from scratch? If so, if you can aim me to directions I won't have to waste tech support's time.
    My additional question on a similar vein: I also have a Time Capsule (second time capsule) which is plugged into the wireless router using ethernet cable for use with a windows notebook running windows 7 which backs up wirelessly. Do I have to change anything on this Time Capsule (second Time Capsule) as a result of change in name of network (I've already adjusted computer to connect to network)?

    Hi DD,
    If you don't get answers here, try posting in the Time Capsule forum (http://discussions.apple.com/forum.jspa?forumID=1253) and/or the Time Machine forum (http://discussions.apple.com/forum.jspa?forumID=1342).

  • I have a Macbook Pro and a HP 5510 printer. And suddenly a problem printing.

    I have a Macbook Pro, fully updated et cetera, and a HP 5510 printer, with all the updates as well. When I lived in my old place, I never had a significant problem getting the computer and the printer to work together. But I moved in January and even since then I haven't been able to successfully print anything. I've run every diagnostic on the printer, and it is connected to the right wireless network. The macbook pro is connected to the same wireless network, but will not connect to the printer.
    Of course at first I blamed it on the printer, but since January I've been trying everything - I even got a friend to bring over her Macbook pro, and it connected and printed just fine. So obviously this is a problem with the computer.
    So what can I do?
    Terribly sorry if this has been answered somewhere else, but I've been searching and no one that I've found has the same, or similar enough, situation going on.
    Thank you, and help me please!

    Care to share which OS you are using?

  • I have a MacBook Pro 15" and my warranty just ran out! I partitioned my harddrive into two partitions, one with Snow Leopard and the other with microsoft.This morning I turned on my Macbook Pro and it will not boot into Snow Leopard.

    Good Morning,
    I have a MacBook Pro 15" and my warranty just ran out! I partitioned my harddrive into two partitions, one with Snow Leopard and the other with microsoft.This morning I turned on my Macbook Pro and it will not boot into Snow Leopard. I shut it off took out the battery, reinstalled the battery. Then I put in the Snow Leopard CD and booted up to disk utility and The Snow Leopard partion would not show up?? I do see the microsoft partion.
    I also rebooted holding down the shift key and still no Snow Leopard
    Could you please tell me what I can do, what keys do I press on restart any advice to get Snow leopard back.
    thank you.

    Have you restarted holding down the Opt key?  That procedure should give you a gray screen with all of the partitions that exist.  Then select the SL partition for boot.  Also go to System Preferences and Startup Disk, unlock the lock and select the SL partition as the default boot partition, then relock.
