Macbook Connecting Problems

I am trying to connect my macbook pro (2008)  MAC OS X- Verizon 10.6.8 to my Panasonic Viera (http://www.bestbuy.com/site/Panasonic+-+VIERA+-+32%22+Class+(31-1/2%22+Diag.)+-+ LED+-+720p+-+60Hz+-+HDTV/4837516.p?id=1218540194899&skuId=4837516)
I have a VGA Cable from my TV to a VGA to DVI cable into my computer... I have it all hooked up, turned my TV on to PC, and then my screen goes blue on my mac, like it is connecting, then a "No Signal" message pops up on my TV... I have tried restarting my mac a thousand times, and enter FN and F7 at the same time.. Nothing..
Any idea how to fix?

Have you enabled Airplay mirroring in >Settings>Hardware>Display ?
Perhaps also go to the Color tab, and Calibrate.. often incompatible displays will refuse to send a signal through...

  • Macbook connection problem WRT54GS v6.0

    I have a problem on my macbook running OS X 10.4.8
    My airport connects to the router but does not receive a valid Ip address. I can even access admin screen from the macbook, but I cannot get on to the internet.
    I am running a WRT54GS v6.0 router
    I have turned on MAC address filter on my router on purpose. I have my macbook's MAC address stored as an "Allowed client" on my router
    also, I have ristricted the maximum number of DHCP leases to 4 clients [ i have 2 pc's and a macbook]
    I am using wpa personal security setting. I tried both TKIP and AES modes. neither worked [currently using TKIP]
    Although the Airport shows that It is connected to "myNetwork", it does not have an IP address assigned
    please help me

    I changed some settings [which I forget now] in order to join the windows workgroup. It did not work.
    I did a clean reinstall of Mac OS X today
    I did not import anything from the previous install. So all network properties must have been deleted.
    So i was expecting that starting all new would work. but it hasn't yet.

  • MacBook connectivity problem

    I just purchased a new MacBook today. I was going through the initial set up while NOT a home where my Airport Express net work is. While setting up the machine asked how I connect to the internet, (wireless, dsl, cable, etc.) or "This computer does not connect to the internet". I had no choice in order to continue the set up than to check "This computer does not connect to the internet".
    When I got home I tried to connect assuming the computer would see the Airport Express and connect, but no luck. The MacBook does say it is connected, but I cannot open a page in Safari. I have an iMac currently connected with no problems.
    Anyone have any ideas?
    Thanks in advance.

    Have you gone through the Airport Utility? That'd be where I'd start first, otherwise you should be able to manually join your @ home WiFi network via the Airport icon (select "Join Other Network.") Also make sure there isn't any sort of filtering (MAC Address or Static IP) that may prevent a good authentication to your access point.

  • Black Macbook connection problem

    Hello
    We have 4 Apple computers in our household. We're connecting to the internet using an airport express. Three out of four computers (G4 Titanium Powerbook, late 2008 MacBook Pro, late 2008 Alu Macbook) can connect to this AE very quickly and the speed is fine. One computer (black Macbook 2.16 Core2Duo) has problems. When starting up or waking up from sleep it takes about a minute to find the AE, and then when finally connected it's very slow. I tried to set up the AE from this computer and interstingly, then all other computers can not find the network at all.
    Anyone any ideas ?

    I had a very similar problem with a PowerBook G4 that I inherited. The final resolution was to do a complete flatten and reload of OS X, but there are a few steps you can try first that are a bit less drastic:
    Try the following, and check to see if the problem disappears after each step ...
    1a. Delete Preferred Network(s)
    o System Preferences > Network > AirPort > Advanced > AirPort tab
    o Under "Preferred Networks," delete the network(s) you regularly use from the list.
    1b. Delete AirPort Keychain Entries
    o Launch the "Keychain Access" application located in Applications/Utilties.
    o Click on the "Kind" filter at the top, and look for any "AirPort network password" entries...and delete them.
    o Restart, or log out then back in.
    1c. Add Preferred Network(s)
    o System Preferences > Network > AirPort > Advanced > AirPort tab
    o Add the preferred network(s) using the "+" button.
    o Restart or log out then back in.
    2. Run the Disk Utility to repair Disk Permissions.
    3. Turn off the Mac OS X Firewall
    o System Preferences > Sharing > Firewall
    o Click the "Stop" button.
    4. Move System Configuration Files
    (Note: You will have to reestablish your network connections settings.)
    o Go to /Library/Preferences
    o Move the SystemConfiguration folder and com.apple.networkConfig.plist file to the desktop.
    o Restart your Mac. (Note: OS X will rebuild the files that are now sitting on your desktop. If this doesn't resolve the issue, you can move the folder & .plist file back to it's original location.)
    5. Create a New User Account
    o System Preferences > Accounts
    o Click "+" to add a new account
    o Log off, then log back on with the new user account.
    o Try connecting with the AirPort.

  • Resolved my Airport/MacBook connection problems

    So I changed three settings on my base station and now my connection doesn't drop every couple of minutes:
    1) Turned SSID broadcast ON (I did have it off)
    2) Changed to allow 802.11 b AND g (it was set to just g)
    3) Changed encryption to WPA AND WPA2 (it was set to just WPA2)
    So I'm not sure which of these was the real culprit or if it was exactly this combination, but I'm thrilled that my problems are over.

    I am 99% certain it is this:
    1) Turned SSID broadcast ON (I did have it off)
    This is down to chipset incompatibilities between the Airport and the MacBook.

  • Strange Macbook connectivity problem

    I have the latest Macbook with 802.11 a,b,g and N installed and enabled.
    I also have an Apple AirPort Extreme (802.11n) with an Apple TV connected to it.
    Strange thing is that when I enable 802.11n only (5GHZ) on the wireless router,only the Apple TV will connect.
    Nothing I do to the Macbook will allow it to connect at 802.11n. If I reconfigure the Airport to 802.11 g ,a and n the Macbook will then see the wireless network,and connect.
    This defeates the object,as I wanted to seperate the Apple TV and the Macbook from the rest of my 802.11g devises.
    The Airport is connected via a wired connection to a router.
    It opperates in Bridge mode.
    Can anyone help.
    Cheers
    Eli

    If you have the newest MacBook then the following link can help: http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/wa/RSLID?mco=36A 3C0EC&nplm=D4141ZM/A
    You need that update to make your MacBook n compatible. But only the newest one will work. Or if you got the AEBS, and installed the CD, then it should have put it on so you don't need to buy that.

  • Wrt100 and apple macbook connection problem

    We have a WRT100 and having problems getting the mac to stay connected.
    No problems with a Dell laptop. 2 Sony PS3s, Tivo HD, but after a few minutes
    online the mac just loses connectivity. Any suggestions?

    I was having the same problem. This is what I did to solve the problem. Went into the Basic Wireless Settings and: 1. changed Network mode to G only. 2. Which disabled radio band and wide channel options 3. Set Standard Channel to 11 instead of Auto. Not sure which one of these fixed the problem but my powerbook stays connected now.

  • Ipod/Macbook Connection Problem

    Hello Everyone! I recently purchased a 120 GB Ipod Classic off of Craigslist and I think I've been duped. When I returned home, I plugged the Ipod in and connected it to Itunes and reset the unit. I then proceeded to transfer my media (I left this overnight as I have close to 20,000 songs). I checked on it about an hour later and everything seem to be tranferring fine. I woke up this morning, my ipod still plugged into my computer but it wasn't recognized in Itunes. I unplugged it and none of my media transferred. I then tried to connect it to my computer and.... the Ipod shows the screen that it's connecting to my computer do not disconnect, then it flashes and resets. It repeats this loop over and over if I leave it connected.
    I've disconnected it, held the middle select button down to reset it but still nothing. Any help is much appreciated.

    Hey anamorphose13,
    If your iPod displays the "Do not disconnect" screen indefinitely, I'd follow these troubleshooting steps:
    Put iPod into Disk Mode.
    iPod should appear in the iTunes Source pane and on the desktop or in a Finder window, or in the My Computer window.
    If a message appears that says the volume could not be mounted and asks if you want to initialize the disk, choose to initialize iPod's disk. Use Mac OS Extended format (HFS Plus) if you have a Mac, or FAT32 if you have a Windows PC.
    Warning: This process cannot be undone. All of your songs, videos, and other files will be deleted. Always make a backup of your important data.
    Follow the steps to update or restore iPod. If you manually put iPod into Disk Mode it may need to be resetbefore you can use it.
    If you cannot put iPod into Disk Mode after performing these steps, it may need to be repaired. You can arrange for repair at the iPod Service Website.

    iPod only shows an Apple logo and doesn't start up

    Who can shed some light on my ongoing connection problem.
    After upgrading my iPad Air with IOS 7.06, I could no longer connect to the internet.
    I have 2 MacBooks Air, 1 ipad mini and one iPhone 4S running on the same network, and they are all connected to the net and function well.
    So I cleaned up the ipad completely, installed the latest firmware and reinstalled my apps : no connection.
    I tried all things of resets and forgets. No result.
    I have been fondling with my Airport Extreme 5 , but that did not help much.
    This morning I went to a neighbor , hooked my ipad air on his network, typed the password and the thing all worked fine.
    I have tried to connect the ipad air as an ethernet client, but that did not work. „Not enough power“ was the statement
    Ideas anyone ?

    Yes I tried this manyfold. But did not work.  Reading on, I took Tesserac's advice. Shut down router and computer.
    Start router after 15 minutes and wait another 10 minutes before starting the computer.
    Et voila.... everything is back in working order,

  • New retina MacBook Pro - WiFi connectivity problems

    Dear all,
    I've recently purchased the new Haswell 13" retina MBP, and I'm having exactly the same WiFi connectivity problems the 2013 Airs had. I have a solid connection for a short time, and at irregular intervals it just drops out. All of my other devices are still connected and have no problems. I've tried with two different routers/modems, but the problem persists.
    Is this a known problem - with hopefully a software fix in the forseeable future, or do I need to return the MacBook?
    Many thanks in advance for your help,
    Nic

    I haven't got a Retina, but I do have the same wifi problem. And if you've looked at these forums, you'll see it's been going on for years and no one seems to have a handle on what the issue is. All I can say is if I were in your place I'd take it back and exchange it. You have the chance now, so take it.

  • Interne connection problem with Macbook

    I have a new 13 inch white macbook . It keeps on disconnecting with the internet . My PC laptops dont have this problem . I am using AT&T Gateway wireless modem . The macbook would show no connection and then after the diagnostics are run and the browser is closed and re-opened it connects with the internet, it is annoying . I am using safari and firefox both . The problem is more with online banks and online apparel stores not with yahoo or google.Seems the browsers are not compatible with these websites.
    Please help.
    Thanks

    Yes, there are a few sites that are not 100% compatible with Safari OR Firefox, and work ONLY with Internet Explorer. Do the help files or instructions for your troublesome bank or merchant website(s) specify what browser(s) version(s) and operating systems they support?
    Airport (wireless internet connection) problems to your network and/or wireless router are different, and 99.9% of the time, not related to browser compatibility issues.
    Unpredictably connecting or disconnecting from a wireless router is a wireless networking problem, not a browser compatibility issue.
    *Wireless troubleshooting:*
    Can you also connect to your Mac directly to your AT&T wireless router with an Ethernet cable?
    That will help you diagnose what are connectivity/network issues, versus what are browser compatibility issues. If your browser(s) work fine with the troublesome sites when directly connected by wire, then you're NOT having browser compatibility issues. Macs are picky about wireless connections. My original inexpensive 'b/g' wireless router worked fine with my older Windows XP computer and Nintendo Wii, but my MacBook kept dropping the signal every 10 minutes or so. I upgraded to a famous brand 'n' wireless router, and my problems disappeared.
    *Browser Compatibility Troubleshooting*
    Indications of browser incompatibility are:
    Fonts that don't display correctly, such as overlapping or missing letters or words.
    Wrong colors or colors that obscure some parts of the screen.
    Text that displays line by line at the left margin, over colored backgrounds, instead of as a web page.
    Screen display design elements are wrong, such as a color box that seems too large or small for the text displayed on it.
    Some or all of the 'button' elements of the website do not respond to pointing the cursor and clicking, even after refreshing the screen, and the only solution is to closing the browser.
    Look carefully at the Status Bar at the bottom of the browser so see if it displays an Errors count. (Then choose Window, Activity, to see what errors are occurring.)
    If you MUST have 100% Internet Explorer compatibility on your Mac, you can always purchase Windows and IE and install it under Bootcamp, Parallels, VMWare Fusion or similar programs.
    Let me know what you discover.

  • MacBook Pro Network Connectivity Problems

    Hi everyone!
    I am baffled with an issue connecting my MacBook Pro to the internet.  My wifi worked okay until about two or three months ago, when it stopped being able to automatically connect to networks.  I simply used my phone to pick up the IP/DNS information, and then entered it manually into network settings.  Then, last month, that solution stopped working, and I am unable to connect to any network via wifi or Ethernet, even when manually entering IP information.
    I have restarted my laptop and router multiple times.  Reset the PRAM.  Created a new location.  Deleted and added the network again.  Deleted network settings in Library.  Symptoms are not present on other wifi devices – other laptops and devices connect fine. 
    I am running OS X 10.8.
    Any help would be much appreciated!
    Thanks!

    If you're still on 10.8, then you need to update to 10.8.5 (which, itself, has some bugs) in order to rule out the bugs found in 10.8 through 10.8.4. Use the Combo updater -> http://support.apple.com/kb/DL1676.
    If, after updating, your connection problems persist, call back. There's no guarantee that updating is going to 'fix' your problem.

  • Macbook Pro Wireless Connection Problems

    I bought my 13 inch macbook pro 1 week ago and I've had wireless connection problems from day 2 (I think after the updates).
    Problems include:
    - Safari cannot connect to the internet for 5~10 minutes after I turn it on, whether it be from sleep mode or completely off or restart (the fastest connection I got after turning it on was about 40 seconds)
    - Loading takes ridiculously long and eventually Safari cannot find the server
    - Airport signal (on the top right hand corner) is always full when it is not working
    - Sometimes internet works but it is ridiculously slow
    However, when the wireless connection stabilizes, Airport Signal is 2~3 bars full and internet works SOOO well and I love it so much when it does. But the problem is that it stabilizes like 30 minutes to never after I turn it on and it makes me so mad I want to explode this piece of crap in the microwave.
    So I've called apple support, and they made me try four things:
    1. Reset modem, router, and computer
    2. Delete caches, reset Safari
    3. Putting Airport first on the Service Order and resetting DHCP Lease
    4. Connecting with Ethernet Cable then resetting the computer
    None of these worked, and I'm suspecting that the cause of the problem is the hardware (not the aluminum body that's just bs) because my router and modem are working fine (my other samsung laptop is working perfectly). I don't think the problem lies in my network settings either because I did exactly what the Apple technicians told me to do. So after Appleguy made me try all 4 of those diagnostics, he told me to contact my router company NETGEAR because he thinks nothing is wrong with the mac hardware, so I did. The NETGEAR lady told me if one laptop is working and another isn't, there is nothing wrong with the router. So if nothing is wrong with my hardware, software, router, modem, ISP... Why do I have wireless issues????!?!?!?!?!?!?!?!?!?!
    I'm going to return this <edited by host> or get another one with my warranty

    Same thing here.
    I've got a Macbook Pro 15" bought 6 weeks ago, airport express bought about a year ago. All updated with latest software/firmware, etc. Problems include:
    -Sometimes when i pull down the network list, my network isn't even there, yet i'm still connected to it. My airport is appx 10 feet away in an open area.
    -usually after opening safari or firefox for the first time upon sleep, restart, or just opening the program after i had quit it, it is miserably slow. it takes about 2 minutes for pages like msn.com to load. finally when they do, its faster than you can imagine. that lasts for about a minute. then its slow again.
    -when logged into ichat and i send messages, i would sometimes get a "connection timeout" message. my buddy would end up getting the message about 5 minutes later.
    My iphone and dell laptop work fine. i haven't tried running parallels, but if bootcamp works, so should prlls.
    I've reset the modem about 20 times. i've reset the airport about 20 times. i even re-installed my OS on the mac and nothing has done it.
    Weird thing is that i've had my mac for 6 weeks, and this problem surfaced only 3 days ago.
    Clearly its not an issue of any of our ISP's. Due to the fact that this only started for me 3 dyas ago, i'm hopeful that its only a software problem and not something else. Hopefully apple will a) ADMIT THEY HAVE A PROBLEM HERE and b) FIX IT.

  • Macbook Pro (Leopard v10.5.8) connectivity problems

    Computer:
    Unibody Macbook Pro 13" from August 2009 (running OS X 10.5.8)
    Problem:
    Randomly, my AirPort card will turn off and occasionally the computer will freeze up. This issue arose after Apple replaced the Logic Board for a faulty audio-out port. After trying various methods to reset the network, Apple replaced the AirPort card. I am still experiencing the issues.
    +I have recently noticed that the issues have only ever occurred when the computer is running on battery power. The computer is able to be problem-free for days (until unplugged).+
    _*What I've tried to do already (if you're having similar connectivity problems, these may solve your issues):*_
    1) I have cleared out all networks saved onto my computer under "Advanced" settings in the "Network" section of "System Preferences".
    2) I have reinstalled all current updates for my version of OS X Leopard
    3) I have attempted to reset the PRAM (turn on the computer by holding "command" + "option" + "p" +"r" and the power button). Sometimes this will turn the network back on and sometimes it won't. However, even if it works, the connectivity issues still come back.
    4) When the computer has frozen up, I have reset the SMC:
    +For early '09 Macbook Pros and later:+
    +Shut down the computer.+
    +Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.+
    +On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.+
    +Release all the keys and the power button at the same time.+
    +Press the power button to turn on the computer.+
    +Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.+
    Obviously, this also has not solved the problem.
    5) I have gone into Macintosh HD -> Library -> Preferences -> SystemConfiguration and deleted the following Plists:
    com.apple.airport.preferences.plist
    com.apple.nat.plist
    com.apple.network.identification.plist
    com.apple.PowerManagement.plist
    Networkinterfaces.plist
    Then restarted the computer. Just like #3 and #4 this sometimes solves the issue, but only temporarily.
    This problem has become very frustrating because every time I think I have it fixed the issue pops up again. If anyone has suggestions for something I haven't tried, I am more than happy to welcome your input.
    Thanks,
    Mark

    Hi g,
    Software Update will update, but will not upgrade the OS. To upgrade the OS to Snow Leopard 10.6.8 you need to purchase the disc for $29 and install it, then run Software Updates.
    I have no idea if this will resolve your issues.
    Do you have at least 15% free space on your HD?

  • Any wifi connection problems with new Macbook Pro 13" models?

    I currently use a 15" Macbook Pro (about 3.5 years old) that has intermittent WiFi connection issues (intermittently loses signal). This seems to have been a very common problem with this laptop model. My kids, who use Macbooks, have no connection problems. In any case, I'd love to buy one of the new model 13-inch Macbook Pro's but hesitate because of my many issues with WiFi connectivity on my older Macbook Pro. Just wondering if anyone is experiencing connectivity problems with the new model?

    I've never had Wifi connection problems with a Macbook and now with the 13" MacBook Pro I was flabergasted when I took my MacBook down the street to a coffee house with free WiFi. I went to connect to their WiFi and found my own WiFi connection listed. I thought this odd even though I was on the same block as my apartment, my apartment is six stories up. I connected to the Coffee Shop WiFi but it was really slow so I wondered if I could connect to my own home connection. I switched it over and lo-and behold I did connect! It was a good 300 feet away! I NEVER saw this with previously owned MacBooks including the black MacBook and the MacBook offered just before they moved the MacBook up to the Pro series.
    So I'd say they have improved the WiFi nicely.
