    WiFi signals get stronger the closer the machine is to the router and the less interference/blocking of the signal like via walls with metal in them or of thick concrete.
    Since the signal emanates outwards in a sphere, your supposed to place the wireless router in a central location in the building so it covers all areas.
    The power of the router also has a affect, if your router is old or something not that powerful like a Airport Express, it doesn't have the ability to filter out other signals or enough punch to get through walls etc. or cover a large area as effectively.
    If you buy/have a powerful router of newer make and have issues where there is metal in the walls or thick concrete, then you can buy something like OpenMesh and by using Ethernet cables from the back of the router, extend the WiFi signal into other rooms and areas past the blockage.

    Have you tried booting from the Recovery HD to reinstall Lion?
    Boot to the Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    You will need the Apple ID and password used to purchase Lion. If you have not purchased Lion, then you will need to purchase the Snow Leopard DVD and install Snow Leopard then update it to 10.6.8 to access the App Store where you can purchase and download Lion under your own Apple ID. Or you can purchase the Apple USB Lion installer flash drive at any local Apple retailer or the Online Store.

  • HT1544 how can I reinstall the Mac OS X from scratch?

    I have an early 2008 iMac that came with Mac OS X 10.5 leopard. I have bought all os's since then, and Today I am using the most recent one, mountain lion. My question is, how can I reinstall the Mac OS X from scratch? Is there a quick way ? Or do I have to:
    Find the leopard CDs that came with the iMac
    And go through the cd installation.
    Then, can I jump from leopard to mountain lion?

    If your goal is to just reinstall Mountain Lion, you can restart the computer holding the Command and R keys, then choose the reinstall OS X option from the utilities choices presented to you.
    That restarts the computer using the recovery hard drive that was created when you installed Mountain Lion...but note you must have an internet connection when you do this reinstall.

  • I don't know how to reinstall the Mac App Store after I deleted it on my Mac!

    HELP! I deleted the Mac App Store because it hasn't been working for a few days now, every time I tried to download an app it said "Connection Failed" my internet is working and connected properly, I type in all the correct info for my apple ID/Password, it wouldn't let me download any apps and this has gone on for a few days already, so I decided to delete the Mac App Store and reinstall it, but I can't reinstall it, I have to download the whole latest version again, which I can't because you download it thru the Mac app store! By the way i have the latest version for mac, i think heres my version: Mac OS X version 10.9.4, now i don't know what to do..... I'm i gonna have to take this to the apple store and ask? If so what will they say? Or does anyone have a solution? Please leave a response has this happened to anyone else?

    OS X Mavericks: Reinstall OS X Heres the link if anyone else had the same problem!! This is if you deleted not only the Mac App Store, but iTunes, Calendar, whatever came with the Mac (Apps that came already installed on the Mac), if you deleted one of those then you have to reinstall the Mac OS, Note: This one is for Mac OS X (Maverick) my version is 10.9.4, go to that link and follow the instructions if you have Mac OS X (Maverick). Other help: Common Mistake: If you delete the app from the dock then just go to finder and applications folder and drag the app back onto the dock(it was just deleted from the dock NOT your system/computer). Hope that helps others who had the same problem.

    I have a real problem, and I could use anyones help.

  • Why my screen is keeping black screen when i leave the mac book with few hr

    when i leave the mac book pro on a few hours, it kept black screen. i try to press any key and open button, it kept no response. after 3 mins, i press open button again. the mac book appear off. so i press the open button again , it open.
    do i need to change a new mac book pro in this situation? because this is my new computer, i can change a new one within 10 days.
    plz give me some suggestion, thank you!!!

    In actual fact this seems a bigger problem than I thought. Linking the two computers via the Thundernolt cable and selecting cmd F2 no longer shares the screen at all and Apple say it may not be able too in Mointain Lion - What are they playing at, hundreds of customers link computers together and share the screens - Lets hope they are wrong and tell us what we need to do other than move back to Windows.

  • Itunes 10.6.1.7 problem: when I change the file "media type" from 'Music' to 'Podcast' the file disapears from ITUNES. I do this via (1) right click, (2) select 'Get Info', (3) select 'options' tab, and (4) change media type. What is the problem?

    Hi Memalyn
    Essentially, the bare issue is that you have a 500GB hard drive with only 10GB free. That is not sufficient to run the system properly. The two options you have are to move/remove files to another location, or to install a larger hard drive (eg 2TB). Drive space has nothing to do with SMC firmware, and usually large media files are to blame.
    My first recommendation is this: download and run the free OmniDiskSweeper. This will identify the exact size of all your folders - you can drill down into the subfolders and figure out where your largest culprits are. For example, you might find that your Pictures folder contains both an iPhoto Library and copies that you've brought in from a camera but are outside the iPhoto Library structure. Or perhaps you have a lot of purchased video content in iTunes.
    If you find files that you KNOW you do not need, you can delete them. Don't delete them just because you have a backup, since if the backup fails, you will lose all your copies.
    Don't worry about "cleaners" for now - they don't save much space and can actually cause problems. Deal with the large file situation first and see how you get on.
    Let us know what you find out, and if you manage to get your space back.

    Install Mavericks, Lion/Mountain Lion Using Internet Recovery
    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
    Boot to the Internet Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
    Partition and Format the hard drive:
    1. Select Disk Utility from the main menu and click on the Continue button.
    2. After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
    Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
    Note: You will need an active Internet connection. I suggest using Ethernet
                if possible because it is three times faster than wireless.

  • There is a problem when i click the "+" tab to "open a new tab" nothing happens. It use to open new tabs and now it does nothing.

    There is a problem when i click the "+" tab to "open a new tab" nothing happens. It use to open new tabs and now it does nothing. Even when i go to "File" and "New Tab" it still does nothing. The only time i can get a new tab to open is if i go to "Help" and click "Firefox Help" then a new tab with firefox help opens.

    Hi, were you able to resolve your problem? If so, please mark this question as '''Solved'''. Thanks !

  • I updated my iMac to Mountain Lion. All the files were deleted. I have Time Machine backups. When I restart the mac pressing Command R to restore from backup it shows the previous OS X (Leopard) beside the date of the backup. Will it go back if I restore?

    I updated my iMac to Mountain Lion. All the files were deleted. I have Time Machine backups. When I restart the mac pressing Command R to restore it from the backup it shows the previous OS X (Leopard) beside the date of the backup that I want to select. Will it go back to Leopard if I restore it from the backup?

    No, it won't revert to the prior OS X but you you may have third party apps installed that were compatible with Lion that may not be compatible with Mountain Lion.

  • I have a problem when I run the DTP

    hello
    the day before , I load  data in a PSA "MASTER DATA" mode full,
    then in the morning  I load data again this "MASTER DATA."
    I can see  that the same lines do not not present a problem but the lines were changed, i have a problem when I run the DTP?
    I get this messages errors:
    .« the time interval & (from/to) for the data
    ecords 1 & and 2 & overlaps in characteristic 0COSTCENTER &.u201D
    u201CMessages for data records saved; request is red acc. to configurationu201D
    best regard
    francoise dinatale

    As this is a master data load, the attribute change run is mandatory before performing the next load.
    The probable reason for this is in the master data table there is an entry for a characterisitic value and the load resulted in another value. The difference between these two records is the object version. Exisitng record will have A version and the changed record has M version.
    So when we active master data(attribute change run ) then M version overwrites A version and hence on a net we have only one record in master data table.
    Post the above task if we again load master data, as is in your case, then the record will find its place in M version.
    As the activation is not performed(probably), the system finds it difficult, with previously loaded M version and currently loaded M version and hence the reason for the message.
