After yosemite update, my wifi periodically runs very slow and sometimes disconnects

Hi there,
After the yosemite update my iMac's wifi has been running super slow, nothing to do with my own internet connection as it's fine, as other computers and devices works fine on the internet.
Recently the only way that I have fixed it is to turn my wifi off, and then turn it back on again, this fixes it for a short amount of time before I need to do it again.
Any suggestions?
this was a screenshot during the time that it was running slow, during the test it went down to about 0.02 mbps download, then spiked to 2.5mbps, causing the average of 0.19mbps.
Upload speed seemed average for my internet connection.

Please look over and use Troubleshooting Wi-Fi

  • Query runs very slow and sometime freezes

    Hi Experts,
    I have just installed SAP GUI 710 but when i open a query in analyzer it runs very slow and  if the variables are set for more than 6 months it just sits there and finally times out. It takes at least 5 minutes to open the query if it opens at all. Can you please advise me on how to resolve this issue??
    Thanks, point will be awarded.

  • Hello, I just bought the apple Airport Express, and I am suffering from lots of difficulties. It is in the middle of out apartment and from a bedroom, it runs very slow and sometimes doesn't even load. I would like to know what might make it stronger.

    Hello, I just bought a Airport Express, and on the first day it has a a weak signal. It is very far from my working space and my apartment has very thick walls that might be blocking the signal. I would like to know if I can do anything to make it stronger or faster. If you know please reply.

    You need to move the AirPort Express closer to the bedroom.
    You can leave the modem at its current location and purchase a longer Ethernet cable to move the AirPort Express virtually anywhere that you want. The closer that you can locate the AirPort Express to your working space, the better the signal will be.
    Standard lengths of Ethernet cables are 6 feet (2 meters), 25 feet (8 meters), and 50 feet (15 meters). Any computer / electronics superstore will have a selection of Ethernet cable from which to choose.

  • After update to Lion Numbers became very slow and clumsy.

    After update to Lion, Numbers works very slow and clumsy. Any solution to fix this problem?

    Don't know about being "slow" - I've always felt it was slow.  I could run Office XP (maybe 2000 - not sure) on an 133 mhz Pentium and it was faster than Numbers on my late 2008 Aluminum MB.
    But I've had other issues under Lion with it.  It seems whenever I first go to my spreadsheets after the computer has been asleep - even if it is some time after waking it up - and start to enter some numbers, I'll get a beep and see that what I tried to type didn't come out right and I have to do it again.
    I was wondering if it was something to do with the auto-save versions maybe kicking in when I first start to enter info, but before I finish the first entry.

  • I have mac, desktop v. 3.6.16 will not update to 6. My mac laptop is updated to 6 but runs very slow. How do I get my laptop back to 3.6.16

    Desktop is an imac is 10.6.8 running firefox v 3.6.16 and runs well. My mac laptop also 10.6.8 automatically upgraded to 6.0 and runs very slow, and I do not like the layout of the toolbar. How do I get my laptop back to 3.16.6

    Now it is clear which it wasn't before! We can't see what you have done or not so a good descriptions does help when communicating.
    If you have done all you say and some restarts too I would advise you to do the install of 10.6 from the installation disc. Restart the computer and then install the 10.6.6 Combo update. You just install "on top" of what you have. No archiving or formatting.

    Things That Can Keep Your Computer From Slowing Down
    If your computer seems to be running slower here are some things you can do:
    Boot into Safe Mode then repair your hard drive and permissions:
    Repair the Hard Drive and Permissions Pre-Lion
    Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    Repair the Hard Drive - Lion
    Boot from your Lion Recovery HD. When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
    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.
    Restart your computer normally and see if this has helped any. Next do some maintenance:
    Suggestions for OS X Maintenance
    For situations Disk Utility cannot handle the best third-party utility is Disk Warrior;  DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
    OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep.  Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger.  These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
    OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
    I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
    For emergency repairs install the freeware utility Applejack.  If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line.  Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
    When you install any new system software or updates be sure to repair the hard drive and permissions beforehand.
    Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
    Carbon Copy Cloner
    Data Backup
    Deja Vu
    SuperDuper!
    SyncTwoFolders
    Synk Pro
    Synk Standard
    Tri-Backup
    Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
    Additional suggestions will be found in Mac Maintenance Quick Assist.
    Referenced software can be found at CNet Downloads or MacUpdate.
    Additional Hints
    Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
    Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
    Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
    Check for applications that may be hogging the CPU:
    Open Activity Monitor in the Utilities folder.  Select All Processes from the Processes dropdown menu.  Click twice on the CPU% column header to display in descending order.  If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar.  Click on the Force Quit button to kill the process.  See if that helps.  Be sure to note the name of the runaway process so you can track down the cause of the problem.
    Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.

    1. upgrade to lion, which should over write previous software and the reasons for it being slow.
    No, you don't want to upgrade over a buggy system, Lion has issues of it's own that will only complicate matters, plus Lion is slower than Snow Leopard.
    Learn all the pitfalls before you upgrade to Lion, like all your Rosetta/older programs will no longer work and more.
    Leave Lion for a new hardware purchase is my advice, it's still got plenty of security and other issues.
    For your performance, your likely better off replacing the hard drive with a 7,200 RPM model and maxing the RAM, download the free MacTracker to find out your specs, and OtherWorld Computing is good for videos, tools and parts.

    2. Format the hard disc and reinstall snow leopard.
    That will work, provided your data is off the machine first.
    Now how do i reinstall snow leopard as it was an online purchased upgrade from leopard.
    The 10.6 Snow Leopard disk that you upgraded 10.5 Leopard from actually has the full OS X 10.6 on it.
    All you have to do is stick the disk in and hold the c key down while booting, use Disk Utility to erase the entire drive, quit and install 10.6.
    Of course your not going to get the free iLife that came with the 10.5 grey disks, see if you can first install 10.5 with the same methods, then setup with the same user name as before, then upgrade to 10.6
    I think Apple nulled booting off the 10.5 disks, but it won't hurt to try.
    Another method would be to install 10.6 fresh by itself, then use the program called Pacifist to extract iLife from the 10.5 disks.

  • HT1338 Is there a Mac System Clean-up? My computer is running very slow and freeze all the times

    I don't know why my computer is running very slow and keeps freezing all the times.  It would take at least 2-3 min to load up after the not using it for 5 min.  For instance when I type my paper or doing anything on the computer and leave for a fews min after come back it would not start and the icon keeps on spinning.
    Thanks

    Pretty much all "clean-up" utilities will just make things worse.
    You need to determine what it is that is causing the problem.
    How much RAM do you have?
    For the following, report what you get when the system is running slow and beachballing.
    Open Activity Monitor (Utilities folder) and click on System Memory tab at the bottom of the screen. What does it say for Page Outs?
    Also, at the top of the window, select All Processes. Click on the %CPU header until the arrow points down. Anything pop up at the top of the list that is using a very high percentage of CPU?
    What you describe can be caused by incompatible third-party software. Boot into Safe mode and see if the problems still exist. Safe mode will be a little slower than normal, but you shouldn't see the system freeze up.

    wen6275,
    It looks like you're actually using a camera or phone to take a photo of your monitor.
    That's not what is commonly known as a "screen shot". 
    It looks like you're on a Mac.  Hitting Command+Shift+3 places a capture of the contents of your entire monitor on your Desktop; hitting Command+Shift+4 will give you a cross-hairs cursor for you to select just the portion you want to capture.
    I'm mentioning this because I fear I'm not construing your original post correctly when you type "I am working with a large files [sic], currently it has 149 layers, all of which are high resolution photographs", so I'm wondering if there's some similar use of your own idiosyncratic nomenclature in your description of your troublesome file.
    Perhaps I'm just having a major senior moment myself, but I'm utterly unable to imagine such a file.  Would you mind elaborating?

    My Mac book Pro is running very slow and the rainbow ball is appearing all the time. Any suggestions for clean up?? I have the OS X Lion system.

    As well as what a brody asked :
    - do you need more RAM? (run Activity Monitor and see how much free RAM - green - is available)
    - do you Restart fairly regularly, e.g. at least once a week, to clear out any swap or temporary files?
    - do  you need to do maintenance, e.g. clearing out caches and unused logs, etc?
