Wireless connecion issues using a macbook

Hi,
RE: Wireless connecion issues using a macbook
After doing some google searches, I have come to understand that there is a bug with OSX power management when running on battery which impacts the wireless connection of the macbook, though Apple geniuses are unaware of any such issue. Please see: http://kristopherjohnson.blogspot.com/2006/08/macbook-wireless-connection-drops. html and type in "macbook wireless connection problems" in google for many other discussions on this issue.
For all those who are having wireless connection issues with a macbook:
Plug in the macbook to use mains power (not the battery) to verify that you are impacted by the same bug (I even find sometime unable to connect to the router when on battery so have resorted to starting the machine with mains power plugged in). If that is the problem then here is a work around (taken from above blog):
Open the terminal window and type in the following command: ping -i 5 google.com
(this will ping the google domain every 5 seconds and maintain the wireless activity thus a connection).
I am surprised that Apple are not acknowledging this well known and widely reported bug and fixing the issue. In my case, I dont mind plugging the machine into mains most of the time and that has resolved the problem, otherwise I hope the above pinging works for you.
I discovered the workaround after ditching my old DLink router (though it had done its time) and buying an Airport extreme (£120), a trip to the Apple store (40 miles drive), trying several different people's machine on my network (frustration) and finally google to rescue, more specifically Kristopher Johnson's blog.
NOTE: My macbook worked fine in the Apple store while on battery power which was frustrating but apparently the problem only arises when connecting to consumer grade networks and not commercial ones, which I dont understand technically.

you can use but you will not get full screen on HDMI output.
Sometimes width or height of the screen was not completely used by ur mac other then that everything would be good.
You need to buy HDMI Output cable for mac something like this

  • Wireless networking problems using iMac, Macbook, airport extreme & express

    Here's my setup:
    iMac in study has 100+ gigs of music on an attached hard drive
    iMac running 10.5.8
    Airport extreme in study
    Macbook in living room that I use Itunes to connect to hard drive in study
    Macbook running
    iTunes on Macbook has it's Media Folder as the one that's on the hard drive in the study.
    Airport express in living room, with direct connection to stereo
    To play music on the stereo, I prefer to use the Macbook to connect to the iMac/hard drive in the study, as I don't want to keep walking into the study to change music.
    Once I get a connection it's usually ok, but the problem is in getting a stable connection in the first place. Sometimes I have to go through a rigmarole where I turn off all the computers and then turn on iMac, hard drive, Macbook, before connecting to the iMac wirelessly before playing music. Sometimes I might need to do that twice before it works.
    If I don't, I get the message in iTunes on the Macbook: Connection failed - The server "macintosh-2" may not esist or is unavailable at this time. Check the server name or IP address, check your network connection and try again.
    Sometimes I'll have access to most songs, but a certain few will get the message above.
    Is my setup the thing that's causing this 'slippery' network connection?
    I'm wondering whether my hard drive isn't fast enough - it's a no-name brand which I got cheaply about 5 years ago. Maybe it's just not up to it? Or is it the fact one puter's on Tiger, one's on Leopard?
    Any advice would be greatly appreciated.

    have you checked for _*wireless interference*_ ?
    download iStumbler (may not work on 10.6) or AirRadar (it has a trial period) and note the channels other networks in your vicinity are broadcasting on. change the channel(s) of your network as far away as possible from those.
    any improvement ?

    possible but i doubt it. in my iTunes test environment, i have a cheap USB drive connected to my TC. iTunes fetches tunes from it via the network, then streams the music back via the network. i have no issues streaming even HD movies in the 10 gig range.
    i assume the extreme is your main router ? what you can try is hardwire as much as possible, i.e. run ethernet cables from the extreme to all Macs. if physical cables is no option (due to location), you might consider *powerline adapters* _*such as these*_.
    here's an interesting read on the subject.
    Or is it the fact one puter's on Tiger, one's on Leopard?
    as long as all Macs are current on the software side, it shouldn't matter.

  • Can I use my Macbook's internet connection on my iPhone?

    Hi
    I am going away to India and we only have wired Internet in our office.
    I want to be able to still use my iPhone to send and receive data
    I don't want to pay roaming fees for this data
    Can I (either wired or wireless) connect and use the Macbook's internet connection??
    It is iPhone 4 (5.1) and latest Macbook Air
    Thanks
    Gareth

    Yes by creating what is called an ad-hoc wireless network with your Mac acting as a wireless router providing internet access for a device such as your iPhone or with another computer via the ad-hoc wireless network created.

  • MacBook and MacBook Pro with 10.6:  Wireless Airport Issues with Cisco

    Long Story but please bear with me:
    Loaded SL on my daughters MacBook and my MacBook Pro. Internet worked flawlessly at our house (WEP encrypted) and on other public wifi. When my daughter went back to her sorority house at college 24 hours later, she could not access the internet using the sorority house network (Cisco Aironet 1800 router and Cisco Airo Access Points).
    Her Airport on the MacBook appeared connected at full strength yet no internet. Two calls to Apple support (they were very nice) did not help. All the following were tried:
    1. Reset PRAM
    2. Deleted Airport and Safari plists
    3. Edited locations
    4. Removed Battery
    5. Others I cannot now remember
    Still no net. However, she could 'pirate' and hop on line with other identified public wifi adjacent to the sorority house. I drove to the sorority house today and tried to get on the network wirelessly using my MacBook Pro with SL. Same identical results to hers. Another MacBook without SL works great and gets right on the network.
    Is this some SL influenced issue with the Airport card and the Cisco system? Weird that both of our laptops work great with several other wifi networks but not the one at the sorority house.
    Could much of what we all our seeing with the internet access problem lie not with issues within our software or computers but with the routers and access points not being compatible? I have very little understanding of this stuff (as you all can probably tell) but the Apple Support people acted like it was a old firmware issue with Cisco and not with SL. Not actually what I wanted to hear.
    Any ideas or suggestions?

    Your description there, particularly the last part, sounds like my problem. At home, we connect using Airport and ADSL which was OK, once SL had sorted out passwords.
    At my office, where there are two wifi systems, I could not get on either, although did have IP numbers on both. The link to the outside world is via a proxy which uses a PAC file. Network Diagnostics reported each time (whatever I did) that the link to the server was OK, but the Internet was not.
    I created a new Location with identical settings (typing them in and not copying) and the only visible difference is that the new location has no DNS numbers -- I had not noticed that before. The moment I pressed, Apply, the computer was online.
    I was guessing that there was a conflict in a .plist file somewhere; but now I wonder if DNS might have been the reason (the DNS number usually used is the one from the router itself).

  • 17" MacBook Pro to 30" HD Display issue using Mini DisplayPort to Dual-Link DVI Adaptor.

    Just replaced the Western Digital hard drive on my MacBook Pro with a SSD now running Lion 10.8.2, (updating from Snow Leopard latest version).
    I have a 30" HD Apple display monitor and very much love using it.
    The issue.
    The MacBook Pro will only allow the 30" Monitor to display its top resolution when the unit is closed, when it is open it shows either 2 screens or mirrored screens depending upon the settings, but not at the top resolution capable by the monitor.
    Now, when I was using Snow Leopard on the previos hard drive, I could close the MacBook Pro and put the computer to sleep also putting the 30" Monitor to sleep, I could then wake the computer while it was closed with my external keyboard and the screen would wake showing the FULL resolution possible on the 30" Monitor.
    Then I could open the lid of the MacBook Pro and the screen would stay black allowing ONLY the 30" HD Monitor to be used effectively as a desktop computer, without the complication or need to display 2 screens or mirrored screens but most importantly the fans wouldn't need to work overtime due to the MacBook Pro being closed cutting off vital ventilation through the 2 air ducts to the left and right of the keyboard.
    For some reason I cannot do this with Mountain Lion, the compluter needs to be closed in order for the 30" Monitor to display top resolution, and the fans are working overtime and the unit is getting really hot.
    My concern is that the MacBook Pro will overheat, the screen will be damaged as the MacBook does get exceptionally hot when running design and audio packages, even Adobe Flash sets the fans off, and lastly the computers speakers are muffled which is more of a moo point.
    If anyone could shed some light or offer a solution I would be most appreciative.
    My specs:
    MacBook Pro 17" Mid 2009 3.06 Intel Core Duo, 8GB 1067 MHz DDR3, NVIDIA GeForce 9600M GT 512 MB, OS X 10.8.2 - connecting to an Apple 30" HD monitor with a Mini DisplayPort to Dual-Link DVI Adaptor.
    Thanks

    Thanks for your quick reply! I want to think I'm not technically challenged, but... are you saying to go from minidisplay on macbook directly to the firewire in the back of the monitor? Or should I try to attach it to that ugly bunch of cables at the end of the monitor cable (dvi, usb, firewire and the power adapter thingy)? Either way, it seems like I might need yet another cable? Like Mini-display to... ?
    I feel like my mother asking these questions... At any rate, when I called the guy at apple support last time he acted like it was a Miracle that I had anything on my cinema display at all if I had a minidisplay cable plugged into the thunderbolt port. He said that didn't work (but obviously it did, at least a little) I DID get a picture, it just wouldn't display at the 2560x1600 resolution. More like 1680xsomething. fuzzy and big. I want my pretty picture back.
    Thanks so much for your help.

  • I have just acquired an iMac desktop. I want to sign on to my airport wireless network, but cannot remember the password. How can I access the password or reset it. I already use a MacBook Pro and an iPad on the network.

    I have just acquired an iMac desktop (about 4 years old). I want to connect to my Apple airport wireless network, but cannot remember the password. How can I access the password or, if necessary, reset it. I already use a MacBook Pro and an iPad on the network and don't want to jeopardize what already works well. I am not all that computer literate.

    How can I access the password or, if necessary, reset it.
    Read the user manual that came w/your Airport router or you can cross-post in one of the  AirPort Forums for instructions. 

  • Using my MacBook as a wireless hub?

    I've had my MacBook for a couple of months now and I love it. I recently got a next-gen video game console with internet capabilities. The problem is that my router is all the way on the other side of my apartment. I could buy a 100' ethernet cord, but I really don't want to have to deal with that wire every time I want to use the internet for my console.
    I know the MacBook is capable of a lot of cool stuff, and I was wondering if it's even possible to connect an ethernet cord between my console and my MacBook and use my MacBook's wireless card to connect to my router. That way, I could bring my MacBook out to the main room, and no one will trip over any wires. Is there maybe some software that can facilitate such a connection, with the MacBook as a middle man for a wireless connection? Does such software even exist for a personal computer?
    Obviously there are some sort of wireless availabilities offered for my console, but I'm skeptical of the expense and reliability.
    Probably a stupid question, but worth a shot, right?
    Thanks in advance.

    I don't know about that - but you could try something like the Netgear XE102 Powerline Ethernet Adapter. You can plug in one near your modem, and then one near your video game counsel and just run a short ethernet cord. This is a cheaper option than buying the 360 Wireless Adapter, and you wouldn't have to run the cord through your house.
    They go for about 50 bucks on Amazon.
    Sorry I couldn't help more specifically - but this could be a good option.

  • Issues using macbook with bootcamp and external apple monitor

    I am having issues using an apple external monitor connected to my macbook with bootcamp - in particular, if i connect the monitor to the computer when the computer is already on, it won't work. Also, when i disconnect the monitor fromt he computer, the computer screen will go black and I'll have to re-start
    Anybody experienced the same and can help?
    Thx

    just make sure that while its standing on its side there aren't any plugs or cables on that side. I'm not familiar with the mb port setup, but having power, two usb, and a display cable could prose a problem for sideward standing if they are on separate sides of the machine.
    as the first commenter mentioned the orientation of your computer is irrelevant, but you wouldn't want to have the weight of the laptop sitting ontop of a usb or video plug that's coming out the side.

    Thank for the quick response, is there any way of syncing video files wirelessly from IPhone to Macbook or can this only be done by connecting IPhone to Macbook using USB Cable.

  • Using Apple Bluetooth wireless keyboard/mouse with a MacBook

    What is required to use a MacBook with the Apple Wireless Bluetooth Keyboard and Mouse?
    -- i.e., what 'setup' is required to get the MacBook to recognize those devices and respond to input from them?
    Thanks.

    To be able to use the mouse and keyboard to full effect, such as key combos on boot and all the mouse buttons, its best to install the drivers from the cd that came with the mouse and keyboard.

  • HT4245 i use a macbook pro which came with facetime i have an iphone 4S as well. whenever i use the wireless on my iphone i can facetime with ease however when i use the same wireless for my mac to facetime the call always gets disconnected.

    i use a macbook pro which came with facetime i have an iphone 4S as well. whenever i use the wireless on my iphone i can facetime with ease however when i use the same wireless for my mac to facetime the call always gets disconnected.

    To use factime on your Mac, I believe you will need to use your email address to do so instead of your wireless number.  Since you can't make calls on the Mac.

    Got it. Thanks. I deleted the mouse (not an apple, but a logitech which has worked fine for me) and then re-discovered it and it's working. Appreciate the advice.
