MBA drops wifi when using an external monitor

My MBA 1.6 GHz has an issue when using only an external monitor. That is when re-awoken after a sleep, with the portable's monitor closed and using both an Apple external keyboard and mouse, my wifi connection to my time capsule drops. It does this consistently and I suspect a hardware issue as the same thing happened under leopard.
Is anyone experiencing this issue? Does anyone know of a test I could preform to establish what is failing? Does this require a hardware repair? Any help with this would be appreciated!

I am having an identical problem with my Mac Air.
It seems we aren't alone either: http://discussions.apple.com/thread.jspa?threadID=1401466&tstart=60. Seems to be some sort of interference issue.

    I think I found the answer to my own question (no thanks to Verizon)!
    I found this article online which was written recently (2012) and explains the WIFI - Bluetooth interference pretty well. Here is the link:
    http://www.ecnmag.com/articles/2012/03/wi-fi-and-bluetooth-coexistence
    The way it has been explained is that if the WIFI & BT radios are on the same chip and using the same antena to send and receive, they WILL interfere no matter what. Having them on two different chips is the best way. But Frequency Isolation (Adaptive Frequency Hopping (AFH)) is a way to reduce interference when they are both on the same chip (as it is in Galaxy Note 2 & S3 - they have Broadcom BCM4330 for wifi/bluethooth/FM) which I guess needs to be addressed in a software update (or may be it already has and is not working well). The last solution is to use 5GHz band for WIFI.
    There you have it. But please let me know what you think and if you have found out anything else.
    Thanks

  • My macbook has problems streaming video when using an external monitor

    I have a MacBook from 2007.  I have a converter so that the MacBook can be connected to an external monitor, and have connected it to my TV.  This works fine, but if I am streaming videos and trying to watch on the TV, the streaming becomes very choppy, almost like the wireless connection is too slow.  If I unplug the computer from the TV, however, the streaming returns to normal.  I previously connected to a TV with an S-video connection and the problem did not seem as prominent.  Now I am connecting to a HD tv using an HDMI connection.
    Any suggestions for how to alleviate this?  I haven't updated or upgraded the memory or RAM, possibly that would help?  Would the amount of files I am storing be causing the problem?  I currently have 50 GB available.
    Thanks for any help!

    Make sure your Mac is set to a resolution and frequency that your monitor supports.
    The other possibility is that your graphics card is fried, but that seems unlikely since your computer is new. Before too long, you should make sure your graphics card is OK using the Apple Hardware Test, but I'm not sure how reliable that is because it claims that my partially broken graphics card is OK.

  • HT3131 how to sleep a macbook pro when using an external monitor and a wireless keyboard and mouse

  • X201 Keeps Dropping Wifi When Using A MiFi Device

    I have a Verizon 4G LTE MiFi device that I use with a variety of devices including a couple of Thinkpads and an iPad. I have absolutely no connection issues with the iPad and Thinkpad T500 but when I connect using my X201 (with the Intel 6300 AGN card), it loses the connection to the MiFi device intermittenly. This ONLY happens when using the MiFi. It does not happen when connected to the router at home or at work.
    Anyone else experiencing this? What is causing this? What was your solution?

    If you are using an Access Connections profile to connect to the MiFi device, make sure that the Advanced Configuration setting (on the second screen of the profile) is set to Maximum Performance (in fact its good idea to check all your profiles and make sure its set to Maximum Performance).

  • Dock doesn't realign when using an external monitor (an HDTV in this case)

    After upgrading to Snow Leopard, I've run into a new problem.
    I hook my MacBook Pro 2.2 up to a 32" Vizio HDTV often. I keep the MBP in sleep mode until I plug my DVI->HDMI cable into it. I wake it with my Logitech M555b bluetooth mouse. Normally everything kicked in fine, under Leopard. Now, under Snow Leopard, my dock does not line up right. I have it positioned to the left side, and when first displayed on the TV, the bottom portion of it is not shown. I have to move the dock to the right or bottom for it to completely re-appear, then I can move it back to the left, where I prefer it.

  • When I close my laptop lid and it goes to sleep so that I can use an external monitor, monitor does not turn on when I hit a key to start laptop

    When I use my external monitor, I cannot get it to work after awakening my laptop using any key.  My monitor won't light up although laptop keyboard is backlit showing that it has come out of sleep mode.  Why does the monitor not get the signal from the laptop?

    I still cannot figure out why it doesn't always work.  All parameters were met and my bluetooth keyboard is set correctly to wake the computer.  My keyboard becomes backlit, but my LG monitor does not pick up a video signal and is black and my laptop monitor is off.  The only way I can get out is to hold on button on laptop until it shuts down and I can start up again.  This happens on an intermittent basis.  Sometimes it works and other times I get black screens.   I need to know if I can use command F1 to get the laptop to detect the display or is their another key combination to send the signal to the external monitor when I can't see anything because I hate to do a hard shut down to get out of this mode!  Please advise!

  • Can I use an external monitor as an extension to my workspace

    Could anyone please tell me if I can use an external monitor such as an apple 20” or 30” display as an extension to my workspace. I am using an apple 17”1.5 power book & I would like to drag & drop[p photos etc. from one monitor to another etc.
    17"powerbook 1.5   Mac OS X (10.4.6)  

    yes, when you connect an external display you can either mirror the laptop display, or have it act as an extended desktop
    this needs the mac to support extended desktop rather than just mirroring, for instance i think ibooks can only mirror but powerbooks can do both

  • How do I use an external monitor with my MacBook??

    Hi,
    I recently purchased my MacBook, but when I am at home, I want to be able to use my MacBook like a normal computer, by plugging a keyboard, mouse and my existing LCD monitor to it.
    What do I need to purchase to enable this and what system settings do I need to adjust to get my monitor to work?
    Could I have my laptop closed while i am using my external monitor? How do I do this? I don't want my MacBook open, while I am using my monitor!! Can someone please give me a simple step by step guide on how to turn on and use my laptop which my external monitor plugged in.
    Thank you very much for your help.

    Can you read it ? http://discussions.apple.com/thread.jspa?messageID=3510076&#3510076
    Shortly,yes,if your Display connected,just close it and than click the mouse it'll wake up in external display.

  • MBP logs out randomly when connected to external monitor.

    My early 2011 MBP laptop (OS Yosemite 10.2.2) recently started logging itself out.  I narrowed the problem to the external monitor which is connected with a Thunderbolt adapter. I installed Thunderbolt firmware update 1.2, that did not correct the problem. When I disconnect the external monitor, the problem went away. Is there something I can do to be able to use the external monitor again?

    I know that both displays will turn blue when it is connected, but it turns blue and comes back after the display is connected. It will become blue during a Keynote presentation, while Front Row is on, and while nothing is happening. It doesn't matter if it has been connected for five minutes or two hours, they both change to blue screens and happen very often and in no particular time interval.

  • Garbled display at startup when connecting to External Monitor - MBP Early 2011.

    Hi,
    When i connect my Early 2011 MBP to an external display i get a garbled display at startup.
    I then have to disconnect the hdmi cable to the external monitor, after which the display clears up (on the laptop) and then when i reconnect the external monitor, it works fine. The problem with this process is that i have to do it each time i start/boot my laptop with the external display connected. The display mode is currently set to mirror displays if that helps.
    Would appreciate any advice users with this kind of set up can provide. Thank you in advance.

    Welcome!!
    It could be that you are using the external in "mirrored mode" with the res set above the max res for the MBP screen. On my Late 2007 MBP, the F7 key toggles between mirrored mode and "spanning" (or "extended desktop") mode and System preferences will let you set the two displays independently. I use an external monitor in spanning mode and have not experienced a problem as I have the internal display prefs set to a comfortable res for its hardware.

  • OSX Mavericks Keeps Restarting at Random Times When Connected with External Monitors

    Starting today, my MacBook Pro started crashing with the below panic report. It appears to only happen when I connect external monitors to the Thunderbolt port. I've been using multiple monitors for the last 6 months without issue.

    Starting today, my MacBook Pro started crashing with the below panic report. It appears to only happen when I connect external monitors to the Thunderbolt port. I've been using multiple monitors for the last 6 months without issue.
    Thanks in advance.

  • Can macbookpro be used with the lid closed while using multiple external monitors

    I want to use macbook pro with external monitors and be able to close the lid on the laptop, but can't figure out how to make that works with multiple monitors.  I currently use two external monitors with the laptop monitor as my third.  All are independent monitors and I accomplish this using the matrox diamond bvu-195 product (one for each external monitor).  Now I would like to add a third external monitor and be able to close the laptop lid - kind of like you would do with a docking station for a Windows laptop.  Anyone have any suggestions as to how to accomplish this?

    Connecting your present two external displays via USB has left your MBP's Mini-DisplayPort available for a third. Depending on the monitor's available inputs, buy a mini-Displayport-to-VGA, MDP-to-DVI, or MDP-to-HDMI adapter and the appropriate cable to make the connection. I would expect that adding a third monitor to your GPU's workload might cause your already slow USB-connected monitors to slow down farther, but you'll have to see whether that's true and, if so, how tolerable it is in your work.
    As for what will happen when you close the built-in display, I suspect that what happens if you do that now will continue to happen if you do it with a third monitor connected. If you can now close the display and run the machine in closed-clamshell mode, I expect you'll still be able to do so after adding the third external screen.

  • How do I use two external monitors with my laptop?

    I have a new Pavilion dm4-301 d cl Entertainment PC.   My OS is Windows 7.   I am used to using two external monitors with a docking station.   This new laptop does not have a docking station.  What do I need to get  to use two external monitors?

    Certainly not without a dock but even with, HP laptop docks pretty well limit you to one of the external monitor ports, even if there are two on the dock. We have used a device called an Atlona AT-HDPIX2 which is a usb to hdmi adapter. It provides a third monitor capability for a laptop....use the native external monitor port and the internal laptop display and then this device gives a third monitor which is full configurable from the Windows 7 display interface...clone, extend, etc. It allows full HD resolution and is responsive enough for even light gaming.  HP makes no true docking station for your laptop. 

  • I've got a MacBook pro 15' running 10.6.6. I want to use an external monitor for my graphic design work running Adobe software and thought I'd try an HD TV. I ran a Mini Display to HDMI lead to the TV but the picture quality was disappointing.

    I've got a MacBook Pro 15' running 10.6.6. I want to use an external monitor for my graphic design work using Adobe software and thought I'd try an HD TV. I ran a Mini Display to HDMI lead to the TV but the picture quality was disappointing. I also tried a Mini Display to VGA lead and that wasn't much better. I tried all variations of resolutions in System prefs - Displays but nothing helped. Am I getting something wrong? Thanks all.

    In addition to pixel density, you are up against the translation driver card in the TV.
    If you read the fine print of computer-resolution-capability in the TV user guide, you will see a chart as tall as the manual page.  At the top is the smallest resolution capable, at the bottom is the full use of the 1080p in the TV.
    Mac falls into the top 25% of the page, maxing out at 1366x768 often.  This is because the TV control card is expected to do too much of the work, but is not designed for computer-monitor processing.
    I looked at the resolution charts on 2 TVs before deciding to buy a 1080p LCD monitor that has a TV interface/connector.  Computer monitor first, TV second.  But the thing is only 27 in.  Good thing TV is not as important to me as it is to others.
