2.4 ghz MBP and a 2.4 ghz cordless phone

I just got my Macbook Pro 15 inch 2.4 Ghz and found out that my 2.4 Ghz cordless phone was interfering with my Airport Extreme Base Station and MBP wireless connection. I had to go into the Airport utility and change my settings. I have a Mac Mini 1.5 GHz as my server (so to speak).
You have to change the Airport Utility settings to another channel and change the response frequency to 5 GHz to avoid competing with a 2.4 GHz cordless phone. I direct wired my Mac Mini to ethernet and all problems are solved.
Thanks,
Tim

While I've never had this problem, I always was under the impression that both the cordless phones and the 802.11a,b,g,n (2.4GHz) systems 'channel-hopped' automatically to avoid this. The only unavoidable major exception was something like a nearby microwave...then again I'm not an electrical engineer.

  • Airport Express and Cordless Phones

    I have tried a radio shack and a panasonic 5.8 GHz cordless phones and both do not work in the same room as my airport. Any thoughts on brands or other options?

    This is an interesting discovery.
    Airport runs on 2.4 GHz not 5.8 GHz, so there should be no problems between the two.
    Does the Airport work when they are not in the room?

  • Cordless phones and airport express

    I know that 2.4 Ghz cordless phones interfere with the airport express. Does anyone konw if 5.8 interferes with it. Is 5.8 just a different frequency or is it more powerful that 2.4 and would therefore interfere more.
    Thanx

    Most 5 GHz phones do not interfere. However there are some 5 GHz phones that use 2.4 GHz for some signalling so those devices can interfere.
    ...or is it more powerful that 2.4 and would therefore interfere more.
    No it operates at a different frequency.

  • New MBP and existing network

    Hello All,
    I've just migrated from a G4 PB 1.5 to a new MBP and, while I can log into the existing WiFi, I can't see any of the other nodes on the network. I have my wife's MP Black and a Mini acting as a HTPC/Server. I just migrated through using the assistant and didn't change any of the settings yet.
    The Mini is sitting headless downstairs so I used to log in remotely using Chicken of the Sea VNC. Now it no longer is visible, nor do the computers show up via network.
    It's been a while since I set this network up and I know that 10.4.8 has altered some of the security. What do I need to tweak??
    Cheers,
    JC

    A router separates two LAN networks and creates two broadcast domains. The standard Microsoft workgroup browsing will only list what is inside your LAN and never something outside or across a router.
    If you want to access what is on the other side you must manually enter the share with its IP address. If the computer you want to access has IP address 192.168.100.12 then you enter \\192.168.100.10\share.
    But as you want to be able to share freely inside your LAN anyway, I would suggest you set up the WRT as wireless simple access point. That way, you only have a single LAN and a single broadcast domain and thus you can find all other computers if you check for other workgroup computers. Instructions how to set it up as access point are here.

  • Moving Library to New MBP and restored iPhone

    Shortly after I acquired a new MacBook Pro, I had to restore my iPhone 3G and lost all of the media stored on the phone. What is the easiest way to copy my iTunes library from my PC to both the MBP and iPhone. First inclination is to 1) sync the iPhone with the PC to get the music on it, then 2) sync the iPhone with iTunes on the MBP.
    Does that sound doable?

     

  • Put SSD in new MBP and it's slower

    Alright guys so this is something I've been trying to figure out but haven't had much luck.  Previously I had a mid 2010 15" MBP that I put a crucial M4 SSD in.  When I installed the SSD I was getting a read speed of 268 Mb/s and a write of 239 Mb/s.  So yesterday I upgraded slightly to a late 2011 15" MBP and I pulled the SSD out of my old laptop and placed it in my new.  I did completely wipe the SSD and reinstall yosemite.  But when I run a speed test now my write is only 120 Mb/s and my read speed increased dramatically to 390 Mb/s as it should since this is sata 3 capable.  My questions is why would the same SSD be slower in a newer laptop with better specs.  Thanks for any help on this one!

    If you run your car into a tree, do you expect the manufacturer to repair it for free?  Using a MBP and drinking at the same time is hazardous multi-tasking.  Don't do it.
    Ciao.

  • Upgraded to new MBP and now I can't bounce?

    I recently upgraded my MPB and now for some reason, when I bounce, the file is empty/silent. I am using all the same gear and the same templates I used on my old computer. Nothing has changed except the computer. I went line by line through every setting with the old computer and everything is the same.
    Any insights? I tried bouncing in every format both offline and online. Same results. I also opened the file on my old computer and it bounced just fine.
    Help?

    Have you tried trashing logic prefs? Or perhaps copy the prefs from your old computer to your MBP, and substitute the current prefs there.
    Have you looked in System Preferences... and checked the sound settings?
    As a last resort, you can try zapping the PRAM, although that resets every system setting to defaults. Before starting up, press shift-option-p-r (a 'chord') and lift after the second chime.

  • Just Got New MBP and need to reinstall Software

    I just got a 15inch MBP and installed Final Cut Studio 2 which I did not know was 55 gigs. I want to install it on an external HD so I want to reinstall Leopard with my disc I received when I bought my MBP from Apple. Will I still get all of my extras such as ilife with my install disc and will it restore it to factory (as I received it when I first bought it?) Thank you!

    An 'erase and install' will remove EVERYTHING from your harddrive, and if you've already got Leopard installed, that's your only option.
    Reintalling Leopard will NOT install iLife; to my knowledge there are no Leopard+iLife 08 install DVDs. . . just Leopard DVDS. I may be wrong, as I have an old Mac and not a new one, which may come with a software package I've never seen (but I'm getting my GF a new MBP for Christmas!!). I think you need to (and should have) a seperate iLife 08 disk with which you can reinstall iLife.
    A couple of questions and some advice:
    -I assume you have at least a 120gb harddrive. Why do you want to install FCP2 onto an extrnal DVD? If you plan to use that space to store media, it would be a better idea to store the media (i.e. the video footage, etc) on an external drive and keep your FCP application on your internal HD.
    -Also, if you are going to run FCP on an external HD, get a FIREWIRE 800 external HD. They are quite a bit more expensive, but I had a LOT of problems just using FCP1 to edit footage stored on an external USB HD . .. I can't IMAGINE the problems you would have running FCP2 off of a USB external HD.
    -Thinking about it again, where are you going to store your footage? On the same external HD as FCP? I think that will work . . .
    Looking forward to hearing more!

  • Help with new MBP and iTunes

    I need some help fast. I bought my wife a new MBP and in setting everything up we inadvertently setup a new and wrong iTunes account. We haven't transferred anything yet, I want to get this account off her computer before I bring everything from her Win 7 machine.
    Can't find any specific instructions, can somebody help me out?
    Thanks!
    Mark

    It's late so this will be rather short:
    1.  Make sure you update the older version of iTunes to the latest version
    2.  Go into iTunes Settings and Authorize iTunes with your Apple ID and Password
    3.  In settings, turn off Automatice sync
    4.  Connect your iPad and once recognized, right click the device from the left side of the the iTunes screen
    5.  Transfer purchases
    6.  You can then sync
    A lot to digest and I don't have the time to walk you through every step.  If you need to, google the points and you'll find lot's of information on where to find these in iTunes.

  • Got a new MBP and old external hard drive is too full for backup

    I just got a new MBP and got all my data migrated and everything. I plugged my external hard drive in to run a backup, and it apparently is too full to run a backup of the new computer.  Even though all the files are the same (mostly), I guess it's not going to overwrite anything because it's a new computer.  Should I just get a new backup drive and start fresh for this computer.  Should I reformat my old backup drive (and if so, how?)?  Advice?

    You should always have two backups of all vital data in any regard. A good 1TB Toshiba USB is $65
    If there is NOTHING on the external HD you cant lose, format in disk utility > erase > format MAC OSX extended journaled.
    then apply a Time Machine backup to the old HD of your new computer. That will free of a great deal of space.
    However you should still have a 2nd backup of data.  2 backups is 1, and 1 is none.

  • Help!  Brand new MBP and Mid '04 23" Cinema Display cable issue!

    Just got a new MBP, and I can't figure out which adapter I need to use my trusty 23" display. The mini display port to dual-link DVI adapter doesn't look right, and I already know the mini display port to DVI adapter doesn't work.
    Will the dual-link version work? If not, what do I do?
    Thank you kindly in advance!

  • Brand new MBP and the user directory is corrupt?

    hi, i just installd my new MBP and did a sync of my G5 settings (all except bookmarks) added a few things to my desktop and when i rebooted the desktop was cleared and the home directory was missing "Movies" "Music" "Pictures" in the left most column. all that is left is "Applications" and my user home symbol.
    i tried to create a new user and when i did so was given a message that the "home" folder could not be located. weird.
    anyway. i also installed a canon IP4300 driver. can anyone tell me what may be going on? do i need to erase the drive and do a fresh install?
    UPDATE: i see what happened! the User directory somehow got into the Applications folder! no idea how. but i can't seem to get it out. can anyone help me out?
    thx
    Message was edited by: Frank Jacob

    Open the Applications folder and drag the Users folder inside to the top level of the hard disk; you may need to press the Command key when dragging the item and/or provide an administrator username and password. When done, log out and back in. If only the home folder is present in the Applications folder, move it to the Users folder. Rename existing items as needed.

  • New MBP and Boot Camp

    I just got my 15" MBP and am trying to install Boot Camp on it. I updated the firmware from the website with the most recent update and OS X from software update, but the Boot Camp Assistant still says that I need the firmware update to install. If I try to run the most recent firmware update again it says that I'm up to date. So, any pinters on what to do next?

    If the issue is with the firmware update not taking then the procedure at the bottom of this page may help.
    http://docs.info.apple.com/article.html?artnum=303364
    Also make sure you are downloading the 1.0.1 firmware and not just the SMC update.
    http://www.apple.com/support/downloads/macbookproearly2006firmwareupdate101.html
    As someone pointed out in another thread the SMC firmware update does not supercede this, they run hand in hand and the 1.0.1 is still needed for bootcamp to install on the 15"

  • MBP and 24" monitor

    Hi,
    I am getting a 15" MBP and a 24" glossy monitor. When I connect the MBP to the monitor what happens? Where do I type and what do I use as a mouse? Does the $999 monitor come with a mouse and keyboard or are those extra? Do I just plug the MBP into the monitor close the MBP and put it off to the side, then attach a keyboard and mouse to the monitor,or does the MBP need to remain open and if so isn't it going to be distracting? Also would I need to use the MBP as a mouse and keyboard?
    Sorry for the stupid question...
    Thanks

    Where do I type and what do I use as a mouse?
    The keyboard and trackpad on the computer, or one connected to any USB port. The display needs to be connected to the computer through USB to use any of the display's USB ports.
    are those extra?
    Yes.
    Do I just plug the MBP into the monitor close the MBP and put it off to the side, then attach a keyboard and mouse to the monitor
    Yes. See the note about USB above.

  • I have a 15in MBP late 2013 w/ Mavericks installed.  At work, I was hoping to dock the MBP and connect to dual Dell P2414H monitors.

    To do so I purchased (2) DisplayPort to HDMI cables and (1) Thunderbolt to HDMI adapter.  As for setup, I have one monitor directly connected to the HDMI port on the MBP and the other monitor connect to the Thunderbolt adapter. 
    I am getting no signal whatsoever on either monitor.  I've ensured that each monitor is set to DisplayPort.  I can understand a signal issue existing between the monitor and the adapter, but I cannot understand the issue with the monitor connected directly to the MBP via the HDMI port.  I checked System Report > Hardware > Thunderbolt and my Thunderbolt to Ethernet adapter shows, but port2 contains no connected device (this is where the Thunderbolt to HDMI adapter is plugged).  Does anyone know where I can check the status of the HDMI port?
    I'm hoping that the issue isn't as blunt as the monitors not being compatible with the MBP.  I've used my previous MBP with another, older, Dell monitor via a Thunderbolt to VGA adapter with no issue whatsoever.  I've scoured the interwebs with the hopes of finding someone with a similar issue, but I've found nobody.

    When the dock is defined as on the bottom, it will appear on the screen of the extended desktop that is lowest.
    Move the second monitor where the bottom edges are equal or the Dell is lower and the dock will move there.
