Updated to 10.9.5, now I'm losing my wifi connection.

My iMac(7,1) has been running 10.9.4 since early July with nary a problem. A few days ago I finally updated to 10.9.5 and since then I keep losing my wifi connection to my router. One of three things will happen:
1. My wifi connection is intact, but I can't reach any network resource — not the internet, not my home server, not even the router itself. I have to turn off Airport, then turn it back on again. Once it's back on again *sometimes* it will automatically reconnect to the router, other times I have to manually reconnect it to the router.
2. My wifi connection will simply drop. Where I would normally have full signal strength shown in the menu bar, I would suddenly show no signal at all — and not be connected to the router. I have to manually re-select my router to reestablish the connection and get online again.
3. Same as #2, except that after manually re-selecting the router I'm dumped into #1 where I can't reach any network resource.
During any/all of this, none of my other network devices — printers, video game consoles, iOS devices, other computers — are having any problems.
I've tried repairing permissions, cleaning out caches, zapping PRAM, reinstalling the 10.9.5 combo update, repairing the keychain, removing my router password from the keychain, "forgetting" my router connection, resetting the Mac's network connections and re-adding them, switching from DHCP to static, and making a sacrifice to Cthulu. Nothing helps. I *have* noticed that when I boot my Mac from a 10.9.4 clone that I made about a week ago, I have NO wifi problems whatsoever. Whatever problem I'm having is a direct result of 10.9.5.
Any ideas?

I had a lot of connection drops and hangs after 10.9.5. It seems there's some compatibilty problem with the Router / Airport / 10.9.5. Did everything, on my computer and airport with no luck, but what worked for me was to reset the router to factory settings and start from 0.
Some 3rd party routers have compatibity issuses with Mac, if the above doesn't work I will recommend to go back to 10.9.4 if you if a Time Machine, and wait a bit for Yosemite launch in a few days. Becasue I don't think there will be a new 10.9 update available soon.

  • I downloaded a software update on my iPhone. Now it's asking me to connect to iTunes, but I don't have my computer with iTunes to connect to and won't be able to for a few days. What can I do to use my phone now?

    Hi,
    Thank you for your reply, I did go to my general settings, but for some odd reason I don't have a restrictions setting, or a reset setting. I thought I could reset all the setting to see if it could be that, but as I said there aren't any.
    My husband also has the iPad 2, and also did the software update and hasn't had any problems at all. I took both iPad's and compared the settings thinking maybe there could be a setting that could have been changed when the update was done.

    Have you jailbroken either of these devices? Have you used the computer you are trying to update with to jailbreak a device? Have you tried using another computer to do the update? You may have to make an appointment at the Genius Bar to have the device checked, or send the device off to Apple care.

  • Any news on ios 8.0.3 update? Been waiting for it coz of my slow wifi connection after i updated my iphone 5s to ios 8.

    Any news on ios 8.0.3 update? Been waiting for it coz of my slow wifi connection after i updated my iphone 5s to ios 8.

    I have heard rumours of an 8.1 update for developers. I just found another bug in 10.9.5. I am beginning to think that nobody should touch any update from Apple until they can get their very serious Q/A problems sorted out. This is getting bad.

  • I updated my ipod 5 to ios 7 and now it having issues with wifi connection

    I updated my ipod 5 to ios 7 and now it keeps saying my wifi password is incorrect. Ive reset my network settings and it is still not working. any ideas?

    Does the iOS device connect to other networks?
    Does the iOS device see the network?
    Any error messages?
    Do other devices now connect?
    Did the iOS device connect before?
    Try the following to rule out a software problem:                 
    - Reset the iOS device. Nothing will be lost
    Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Power off and then back on the router
    - Reset network settings: Settings>General>Reset>Reset Network Settings
    - iOS: Troubleshooting Wi-Fi networks and connections
    - Wi-Fi: Unable to connect to an 802.11n Wi-Fi network
    - iOS: Recommended settings for Wi-Fi routers and access points
    - Restore from backup. See:
    iOS: How to back up
    - Restore to factory settings/new iOS device.
    If still problem make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

  • Recent update to Snow Leopard. Now itunes missing any device when connecting..

    I have a Macbook Pro. I recently upgraded my OS to Snow Leopard 10.6.3. Now when I connect any device (Touch, Ipad, Iphone 3gs) via the USB cable, itunes no longer automatically starts nor does it have the Device shown on the left side of the screen. iPhoto auto starts and sees the devices. Have I somehow "hidden" my devices? Any advice would be much appreciated. Along with my devices (phone, ipad and ipod), I manage my kids ipod touches and they want new apps.

    Quit iTunes. Open a Finder window and go to User Name>Library>Preferences. Find the file com.apple.iTunes.plist and take that out to the desktop. Open iTunes. iTunes will act like its the first time that you're opening it but your playlists, play counts, ratings will be intact. See if iTunes recognises the iPod now.

  • Now Phone Forgets/Can't Make WiFi Connection?

    Beyond all of my other app issues and operating system force close issues with my Droid Charge (almost paperweight) phone unit . . . Starting two days ago it is now UNABLE TO ESTABLISH A WiFi CONNECTION!!!
    Nothing has changed with the router or password (all of our other WiFi equipment works just fine) and I have even 'removed' the connection from the phone and re-added it. NOPE.
    I am not one who 'Cries Wolf' or takes to conspiracy theories (just a normal professional business person) - And have had cell phones since there were in a bag with battery . . . BUT THE DROID CHARGE IS AN ABSOLUTE PIECE OF JUNK.
    Any VZW assistance is always appreciated.
    ALL ANYONE WANTS IS A PHONE (that's still under contract) THAT WORKS.

    Jim,
    Your problem sounds like it's the phone but do check these things.
    Recheck to see these things:  Go to Wireless & Networks and touch WiFi settings.  It should start scanning.  Go down to Add Network and again add your SSID and Security passphrase.  I say this because it sounds like your phone is not keeping (holding) your SSID and/or security passphrase settings so entering them here may work as opposed to entering then when a network is found through scanning.
    Then go down to Advanced and set the Wi-Fi sleep policy to NEVER and also make sure Use Static IP is checked. Leave IP address and Gateway unused. 
    If this does not work then do a more than 10 Minute battery pull.  This is NOT like a factory reset.  Remove your battery for more than 10 minutes.  Then re-install the battery and reboot your phone and again recheck or reenter your SSID and passphrase.  If that doesn't fix your problem I am fresh out of ideas.

    That message means that you have to restore the iOS software because something went wrong. Follow the instructions here. I hope that you have a backup.

  • I have just sought  to update my lightroom and am now unable to access the develop function and get a note stating that I have reduced functionality what it this about and how do I get my product back

    I have just sought  to update my lightroom and am now unable to access the develop function and get a note stating that I have reduced functionality what it this about and how do I get my product back

    Hi there
    I have version 5.7 and every time I opened it I was told that updates are available and to click on the icon to access these.  Instead it just took me to the
    adobe page with nowhere visible to update.  I then  sought to download lightroom cc and this is when I could not access the 'develop' section due to reduced
    functionality  It was apparent that my photos had been put in cc but no way to access them unless I wanted to subscribe. 
    I have since remedied the problem as  my original lightroom 5.7 icon is still available on the desktop and have gone back to that.  I do feel that this is a bit
    of a rip off and an unnecessary waste of my time though.
    Thank you for your prompt reply by the way.
    Carlo
