• WAP Error Message received invalid key EAPOL MIC (msg 2/4)

  Hello

  can someone help me with this error message received invalid key EAPOL MIC (msg 2/4).

  Timestamp	Gravity	Service	Description
  November 5, 2012 15:11:27	warn	hostapd [4365]	Received invalid key EAPOL MIC (msg 2/4)

  Only, I get this message of a device when connecting to the WIFI network.

  This only happens from time to time. Sometimes it connects without any problems.

  Appriciate any help.

  Sincerely

  This is an error when the STA (the computer) built the package. 2/4 is to indicate the negotiation process where it sends a value for single use with his own microphone. A microphone is a verification of the integrity of the messages (or code).

  Basically, this error is said, everything that this computer is sending is not valid. You can try to make the AP behave differently as force the use of side effects instead of TKIP + AES depending on which product you have. About removing 'mixed' wireless network. As example, try using WPA2 (AES) only.

  These errors are more frequent with TKIP, since it is the nature of TKIP to send one key per package.

• Halo 2 Vista Error Message "invalid product key".

  I bought Halo 2 for Vista last week. I installed, updated with the latest patch and connected with my Live account. When the program tries to download my Live profile it gave me the error "invalid product key". I contacted the seller on Amazon and told him my problem. He contacted Microsoft and verify that the product key was valid and he told me to reinstall and make sure that all software is up-to-date. I grabbed a spare hard drive and install a new copy of Vista and done all updates to Windows. Then I installed the latest drivers for video card, I installed Halo 2. I downloaded and installed the latest patch for Halo 2 and the last program of Windows Live. After all this (about 3 hours), I still get the same message. Anyone at Microsoft have a solution to this? I get the message after logging in to my live account inside Halo 2. I googled the question and it seems to be quite common, however, I have yet to see a fix. Help, please.

  I bought Windows Vista Home Basic in April 2008. Order number: 1000831652. I have the electronic invoice and original original DVD. I had also activated my product then. Later, I installed SP1 and SP2, and regular updates.

  Three months ago I formatted my HDD and reinstalled Windows, SP1 and SP2. However, could not activate my windows. Error message says "PRODUCT KEY ALREADY IN USE. So I re-formated and reinstalled Windows - but received the same error message while activating. I repeated the format routine - install three times during the last three months, but the same result while activating - "PRODUCT KEY ALREADY in USE.

  I also tried activating by phone but no results there either. Kindly help me to activate and register my product.

  Kind regards

• Could not load any websites. I don't get any 'error message', the 'enter' key has no effect in the address bar. Works fine in FF and IE search box.

  Entering a URL in the address bar and pressing on enter does nothing. Or the 'enter' key or 'address arrow bar', to go to the site function. Web site does not load and no error message appears. 'Enter' key works very well in the FF and IE search box, is not my keyboard.

   Tried most of the recommended fixes under the "Error loading websites" article with the exception of "DNS refetching", as typing "about:config" in the location bar does no good as the "enter button" won't function. I've removed and re-added FF back into the windows firewall, removed ZoneAlarm from my system, edited proxy settings, deleted and reinstalled FF several times. NOTHING WORKS!!! I'm a die hard FF fan and this is KILLING me. Please HELP!!!
  

  Start Firefox in Firefox to solve the issues in Safe Mode to check if one of the extensions or if hardware acceleration is the cause of the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > appearance/themes).

• Windows Mail is not refreshing since 09/02/2012. When I try to update using the F5 key, I get the error messages.

  Windows Mail is not refreshing since 09/02/2012.  When I try to update using the F5 key, I get the error messages.  The only way I can see me new emails is to sign on the web page of my Internet service provider, which I don't like.

  original title: windows mail is NOT refreshing

  It would be useful that Microsoft has put a notice to have several products access our email accounts so that us non-technical people could avoid these problems.

  Maybe it's something that Apple should warn the consumer. I have three e-mail accounts and I receive and send all the accounts on three different computers at the same time and have never had this problem. Your case is the first.

• error message saying that it is the wrong key when you use a sticker

  Product key

  I have an OEM version of vista Home premium. I'm trying to load on an acer extensa 5420 using the product key on the bottom of the laptop. When I enter the key, I get an error message saying: it's the wrong key. How can I use this disc to reinstall windows?

  Hello

  The OEM recovery disks are the brand and the specific model

  You can't use a disc from another manufacturer

  How to reinstall Vista

  Contact the manufacturer of the laptop computer and ask them to send you to vista recovery disks to reinstall the operating system back as it was when you bought it

  they do it for a nominal cost of $

  also ask them if you have a recovery partition on your hard drive to get back to the way you bought

  you would normally press F8, F9, F10 or F11 or Alt + F10 or 0 to start to start the recovery process according to the manufacturer

  Ask them of the exact key sequence

  or borrow a vista microsoft dvd; not a HP, Acer recovery disk etc

  Make sure that you borrow the correct 32-bit or 64-bit microsoft dvd to your computer

  they contain all versions of vista

  This is the product key that determines which version of vista is installed
