  Hello

  Remember to make changes to the computer before the show?

  You can follow the below methods:

  Method 1: Restart Windows and try to start the Security Center service.

  If you still receive the same error, make sure that the WMI service is launched and running:

  (a) click Start, run , and then type Services.msc

  (b) double-click Windows Management Instrumentation

  (c) set its startup type to Automatic

  (d) click Start to start the service, and then click OK

  (e) restart Windows.

  Method 2: Restart the service

  Windows logs an error if the service IKE and AuthIP IPsec Keying Modules or the driver does not start, or suddenly, they end.

  To restart the IKE and AuthIP IPsec Keying Modules service:

  To perform this procedure, you must have membership in the local Administrators group, or must you have been delegated the appropriate authority.

  (a) restart the service. You can do this from a command prompt or in the snap-snap-in Services Microsoft Management Console (MMC). Do one of the following:

  ·         Start an administrative command prompt. Click Start, click principally made programs, Accessories, right-click guest, and then click run as administrator. At the command prompt, run the command net start ikeext.

  ·         Click Start, type services.msc in the Search box and press ENTER. In the column name of the Services snap-in, right-click on IKE and AuthIP IPsec Keying Modulesand then click Start.

  (b) if the attempt to restart the service fails, restart the computer. This forces all related and dependent services to restart.

  (c) if the error persists after restarting the computer, then the executable files for the driver or service may be damaged, and the operating system must be reinstalled.

  Note:

  You can check that the IKE and AuthIP IPsec Keying Modules (IKEEXT) service runs by using the Component Services Microsoft Management Console (MMC) or the net start command line tool.

• Mid 2010 MacBook Pro could not be repaired

  Hey guys,.

  My MacBook 2010 Mid Pro unfortunately has a problem with the logic board and fits in this issue:

  https://www.Apple.com/au/support/MacBookPro-videoissues/

  After a match with apple care (which was extremely helpful and friendly), they determined it was a vintage product and could not be fixed by them. So, my question is that since the program is still in business and my problem is a known issue, are there options for me?

  I don't know, but this applies to the 2010 Ant models the way that I read it. This program is for units from early 2011 and so would not apply in a mid-2010.

  I turned my MacBook Pro yesterday and when I went to start it up again today, I pushed the powerbutton comes the startup sound and clear grey screen with an Apple comes up with a progressbar under. about a cm from the bar gets full and then a code appears on the screen for a few seconds, then the computer tries again to restart and it circulates in a loop. I took a photo of the code that is displayed for a few seconds and attached to it.

  What should do?

  I have timemachine copies the MacBook on my TimeCapsule, but I have no idea how to use when the computer refuses to start.

  Try:

  Try these in order to test your system after each see if it is back to normal:

  1. a. reset the PRAM and NVRAM on your Mac.

  b. Macs with Intel processors: reset of the controller (SMC) system management

  2. restart the computer in Safe Mode, and then restart again, normally. If this does not help, then:

  HD recovery start: restart the computer after the ring, press on and hold the

  COMMAND and R keys until it appears the Utilities menu screen. You can also restart the

  computer and after the ringing, press and hold down the OPTION key until the Boot Manager

  the screen appears. Select the Recovery HD and click on the arrow pointing down.

  3 fix the hard disk and permissions: at startup, select drive in the Utilities menu utility. Repair hard disk and permissions as follows.

  When the recovery menu appears, select disk utility. After that the charges of THE select your entry from hard drive (mfgr. ID and car size) in the list on the left.  In the 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 faulty or has failed. (State SMART is not reported on external drives Firewire or USB). If the drive is "verified", then select your OS X volume in the list on the left (subentries under the entry for the road), click the first aid tab, then click the repair disk button. If THE reports any errors that have been corrected, and then run repair disk again until no errors are reported. If no errors are reported, click repair permissions. Wait until the operation is complete, then exit FROM and return to the main menu. Select restart from the Apple menu.

  4 reinstall the 10.10.5 update: OS X Yosemite 10.10.5 Combo Update.

• WAG300N: could not start correctly after power failure

  Hello

  After AC power interruption, I tried to turn on my router Linksys WAG300N, but he won't start properly. I will describe what it looks like and what I've tried:

  I push the power button / stop, all 4 Ethernet LED simultaneous light for about a second, (if there is LAN cable connected, one or more led lights permanently) and power the LED will blink twice at normal speed. After that, both voltage and wireless, led simultaneously for about 1-2 seconds, start power LED flashes quickly, after seconds wireless LED stop light, wireless flash LED again and stop two LEDs for lighting. Second later power LED flashes two times normal speed and the process begins again but without flashing of the LED Ethernet (loop).

  I tried to download the firmware using TFTP, but it does not work. Router did not respond to a ping. After many tests, I noticed that the only time where I can ping router is during normal those two blinks of the power led. I've got 11 times waiting and the response of 1 or 2<1ms, 11="" timeouts,="" 1="" -="" 2="" responses etc... (response="" waiting="" time="" for="" a="" ping="">

  I've tried a few ways to reset the router (based on this forum). It does not help, sometimes after the reset I power the router problems or flashing process stops after a few loops (only one Ethernet LED lightning or router turns off). At the end of a day all supports them to the previous behavior of closure with power LED and wireless LED blinking.

  In the end, I tried utility upgrade Sercomm 2.07 mentioned in this topic: http://forums.linksys.com/linksys/board/message?board.id=DSL&thread.id=52

  This software detects only router after reset, when the router is in unknown mode, Internet and power LED flashes alternately.

  Software detects the device as MAC address and visualize correctly the version of firmware loaded into memory. Looks like it works and flashing memory. While flashing memory, power LED, LED Internet and Ethernet LED flashing at the same time very fast. I tried all versions of firmware available, but it does not help, I still have the same behave after flash.

  I think it could be a problem with the bootloader, maybe that part of the memory is broken, but I did not how to fix it. I found information on the JTAG interface, but I don't know if it will work for router WAG300N and where I can find the appropriate file with bootloader.

  Maybe someone can help and give me the idea what should I / check. Theoretically, I should have left 1 year warranty, but I lost the proof of purchase required for the RMA process. I can't find the place in Poland where professionals can help me, so I think that should do it myself with your help

  I think that's the problem with the power adapter... You should try a different power of the specification of the same card...

• Mackbook does not start even after trying disk external bootable

  Hello

  I have been using macbook for four years until I started face to boot problems with the laptop. The details are given below-

  MacBook Pro 13 inch (middle of model year 2012)

  Latest OS installed - El Capitan (worked very well without any problem since release)

  Upgrade RAM - 16 GB

  Given that I have used to keep macbook in mode 'sleep' while I don't use it, sometimes, the battery runs out and the mac stops. But the last time when he stopped this way was a week back, and since then he has failed to initialize.

  Tried troubleshooting steps-

  1. Try and boot into safe mode - gets stuck during a progress bar
  2. CMD + R in recovery mode - I am able to access the recovery options. Disk utility doesn't show any problem with the default player. Fails to start when the computer reboots
  3. Reset PRAM-start fails.
  4. External drive bootable - an external drive to use for the resettlement of the fresh OS x. Installation complete installation. Data and other settings copied successfully to the new disk. Is stuck on a blank gray screen.
  5. Reinstall a new copy of OS X. Installation complete. Takes awhile to achieve 100% on the progress bar, but then gets stuck there constantly.

  If the default drive would have been corrupted macbook must be able to start with disk utility or external drive would have shown some bad sectors. Your help would be very appreciated

  Thank you
