  My problem:
  
  1. I enter invalid text
  2. an error message is displayed, saying that that text I put in place is not valid.
  3. I press the Add - button the popup is closed. Why? The component is not valid. Shouldn't the blocked popup until all text entry are valid?
  
  How to achieve this.

• Z10 blackBerry network connection problems

  Good evening

  I have a BB Z10 with which I have a few questions... networks shows the device it is connected to the WIFI and data services are on etc, but it seems that the thought system is not connected.  Internet does not work and my email addresses are also kaput.  A message in the e-mail says in written Red settings "device not connected to the network" even if the network connection settings showed that it should be.  I can still make calls and BBM. Any ideas/suggestions please?

  Hello and welcome to the community!

  With a strong carrier network (for example, not only WiFi), I suggest the following steps, in order, even if they seem redundant to what you have already tried (step 1 should translate a message from your BB... Please wait just before moving on to the next step):

  1) register HRT

  • KB00510 How to register a BlackBerry smartphone with wireless network
  • Please wait message "registration" happen

  2) restart

  • Pre-BB10 ONLY devices. With power ON, remove the hood back and remove the battery. Wait a minute, then replace the battery and cover. Power on and wait patiently through the long reboot - about 5 minutes.
  • Peripheral BB10. Hold the top button until the counter reaches zero. Wait for the unit to be completely stopped (for example, nothing appears on the screen, no lights, etc.). Hold the top button until the red light. Wait through the entire boot process. IF this fails, you can try the method of battery-pull above, but it is normally NOT recommended unless nothing else works.
  • See if things return to functioning. Like all computing devices, BB suffers from memory leaks and others... with a hard reboot is the best remedy.

  I hope that will move things again for you! If this isn't the case, then you should contact your mobile provider for formal support.

  Good luck!

  Then, as I have also said, tell me your location (country) and I look at the number of calll activate manually.  Remember, the product key is an alphanumeric code 25-digit 5 sets of 5 digits separated by hyphens: everything else is something else and not the product key.  If you use the product key on the label on the computer, then it must validate even if you must do it manually.

  The start menu is opened using the round ORB in the lower left of the lower task bar on the desktop.  You can not access the screen activation without going through the start menu as I know - although I've never let my computer lose activation, so it may work a little different when that happens (but I have understood that it reduces the features but still allowed what what need to activate the system).  If you get only an activation dialog box, and then continue through the automated process and you must be transferred to the manual process where you can browse the guests until you talk to a human being who willl help you.  Remember, the code that appears in the start menu / computer / system properties / Activation once the machine is turned on is NOT the product key - I don't know what it is, but it has no value in the reactivation of the product.  And the code that is produced by the activation system is not the product key and cannot be used for activation.  You need the code that I described above.

  If the iis code not authentic (maybe not on a label or simply wrote down, - may - with a mistake - or be misread on several occasions), then you will have trouble activating manually or automatically.  When you say it "does not activation" you mean you can not activate automatically or that you contacted the Group activatition by telephone, gave them the code, and they told you that it was not authentic?  If the first case, do it manually as described above. If you are unable to start, then you are wrong about something else with your system and more of a problem with the activation.  Use the computer that you are to get the number and then go to the computer of the problem to talk to them.  If this last, then post it on the genuine advantage Forum listed above and provide him with what they ask and they will test your product key and what they ask and will tell you if it is or is not genuine/valid (and why this isn't if it's not) - so if that is the case, you will know why, it's that you cannot activate.  If this is the case, you have a problem, because without a genuine product key, you cannot activate.  At this time, contact you and discuss the problem with the computer manufacturer and see if they can do something to help.  Sometimes, the recovery disks they sell does not require you to enter an activation key and who can fix the problem (even if it will cost a small fee and you must confirm that before buying the records and you will need to do a clean install to fix the problem).

  There is no deception going on here.  I suspect that you could use an incorrect code (maybe read incorrectly - use a magnifying glass if necessary) or there may be another problem with your system.  If you use a software to get the product code of the system (such as Belarc) rather than the code on the label so if the operating system has been installed by the manufacturer, the code in the system is probably their master image code and not the one assigned to you and you need to use the speciiquement that you are assigned.  If you installed a retail OS version, the system is the same as that supplied with the product and something like Belarc can get it back (if you can get the program installed and running with reduced functionality).  If you used the code for a year or so and all of a sudden, you get this message, so I think there is nothing really wrong with the code and everything just reactivate manually may solve the problem and discuss the issue with experts of validation in the other forum will address the real problem.

  There is nothing else I can do or say.  I don't know why this is happening to you, but it's of course and what I said in this post and messages of before is the only way out of the situation.

  I hope this helps.

  Good luck!

• Windows 7 wireless connection problem

  I just bought a brand new Alienware m17x and all drivers are up to date... .IM with broadcom wireless network adapter. The strange thing is that last night I was on the internet for several hours without any problem using the wireless, but this morning iwas unable to use my wireless internet access. This has happened several times now. Sometimes it says "not connected - no available connections" and sometimes he says "not connected connections are available" when she says, links, I try to connect to the network, but it says "unable to connect to the network. The only time wherever I was able to connect to wireless internet, was when my computer is automatically connected to my wireless network without me having to select the network and attempt to connect. I read things about windows 7, with a mode of "sleeper" for wireless connections or something, and that can be the cause of it and that it is better to turn off or downgrade to xp. I am really frustrated because I am not able to connect wirelessly and I hope you guys can help me find a solution.

   

  Guide to correctly troubleshoot wireless M17x
  with Dell Wireless 1510/Broadcom card
  by Glzmo

  Since many new Alienware M17x all powerful users, especially those who use Windows 7 as operating system there are various problems with their Wi - Fi connection and post threads asking how their difficulty over and over again, I decided to write this guide to show them how to solve these issues properly Commons. The solutions in this guide were created and designed for 64-bit Windows 7, but they may also work in Windows Vista, although these problems were experienced by users of Windows 7 mainly in the past. It could very well be that the problems start occurring in Vista as well with the new drivers and Windows updates.

  I. may not connect to the wireless network and or see the wireless adapter when the Ethernet cable is disconnected
  If you sometimes or always unable to connect to the wireless network, cannot connect to the wireless network when the Ethernet cable is disconnected, unable to connect to a wireless network unless you restart once to get this work and other weird problems to be unable to connect to a wireless network continue with section II. Otherwise, continue with section II..

  Sleep of a.i. Disable on disconnect device
  Some new Nvidia Ethernet drivers have a function called sleep device to disconnect. This is the culprit. Normally, it should only put the card Ethernet to sleep when the cable is disconnected, but it is buggy and thus kill the wireless connection as well.
  Follow these steps to disable this feature on your Ethernet Nvidia card:
  1. open the Device Manager of Windows by pressing Win + break, and then click on Device Manager on the left side.
  2 double-click network adapters.
  3 double click on NVIDIA nForce Networking Controller (Yes, that's indeed wired Ethernet adapter).
  4 click on the Advanced tab.
  5 select sleep on disconnect device.
  6 set the value to disabled.
  7 click OK and wireless should work again (may require a reboot later, but probably not).

  I.b. install different drivers (older) who do not have the device sleeping on disconnect feature.
  The above does not work or if you are not comfortable with these drivers, follow these steps (if step A.i. was successful, you will not need to follow these steps). Take care to create a system restore point before proceeding:
  1. click the Windows Start button in the taskbar.
  2 click on Control Panel.
  3 click on uninstall a program.
  4 in the list, double-click Nvidia drivers.
  5. Mark Remove only the following.
  6 in the box below, only check the Nvidia Network driver.
  7 click Remove and follow the uninstall instructions.
  8 restart the system, if you are prompted to.
  9 download another (older) driver from Nvidia.
  10 install the old driver.
  11 when asked what drivers you want to install, select only the network driver.
  12 follow the installation instructions and restart your system if prompted.

  II. Low or fluctuating wireless connection speeds
  If you have problems with WiFi low connection speeds (such as rates decline over time, the speeds are much lower than they should be, network lag/stutter in online games, loss of light packets, loss of internet connection as LAN works and other weird things) or speeds of fluctuating wildly without apparent reason wireless connection install the version of the Dell Wireless 5.60.18.8 drivers instead of the standard Broadcom drivers. All older drivers will usually cause the speed of connection under normal. Note, however, that you may need to install the driver manually via Device Manager as the pilot was not released for another laptop and is not officially available to the M17x yet - that's why the installer won't work. Take care to create a system restore point before proceeding.
  Here is a step by step how manually install the driver:
  1. download the drivers Dell Wireless 5.60.18.8.
  2 check out the R29128.exe file using an extraction utility like WinRAR or just run it and quit the installation program.
  3. open the Device Manager of Windows by pressing Win + break, and then click on Device Manager on the left side.
  4 double-click network adapters.
  5 double-click the Broadcom 802.11n network adapter entry.
  6 click on the driver tab.
  7 click the button Update driver .
  8 click Browse my computer for driver software.
  9 click on Let me take form a list of drivers for devices on my computer.
  10 click the disk provided .
  11 click Browse.
  12. select the folder that you extracted the drivers you just downloaded in step 1. in.
  13 select the subfolder DRIVER_US (if you are in the United States), DRIVER_JP (if you are in the Japan) or DRIVER_ROW (if you are in the rest of the world), according to the region you are in.
  14 click on the Open button.
  15 click OK.
  16 select the driver that says Dell Wireless 1510 Wireless-N WLAN Mini-Card of the list (you may have to scroll down to see - it presents itself as second to the last in the list for me).
  17 click on the Next button.
  18 you will get a warning that the driver that you are about to install is not compatible with your hardware. Ignore the warning and proceed with the driver installation.
  19 restart your system if prompted to do so.
  20 your new driver should now be properly installed and the speed of your wireless connection in the order.

  III. If all else fails (or you've just had enough of boredom arising from the Dell Wireless 1510/Broadcom card)
  Replace the Dell Wireless 1510 problem with a card half-mini Intel Ultimate N WiFi Link 5300 A/G/N (use the bluetooth as the third antenna antenna or buy you an additional antenna for this). It works very well with the M17x, has better connection speeds to strips of the 2.4 GHz and 5 GHz (this last has speeds really bad on the Broadcom/1510), it has not required to jump through the hoops to make it work properly and much more, it works with standard drivers and Intel maintains their drivers up to date. It is also much more reliable and faster as well, especially on the 5 GHz band, but also on the 2.4 GHz band.

  For more information on the subject of tweaking the settings of your Dell Wireless card, check out the official setting advanced properties: Dell Wireless WLAN Card User Guide.

  I hope that this guide will help you solve your Wi - Fi connection and allow you to enjoy speeds of complete wireless connection on your laptop Alienware M17x.

  Addendum: Quick links in this Guide

  Driver wireless Dell 5.60.18.8 version
  Download the driver for the Mini PCI Dell Wireless 1510 card used in this guide.

  Broadcom 943xx Wireless Driver version 5.60.18.41
  Download the latest Broadcom driver as an alternative to the Dell a little older driver who may or may not solve the problems more. Some have seen more success than with the 5.60.18.8 drivers with it (you need to use the 802.11n network adapter driver rather than at the entrance to Dell Wireless 1510 Wireless-N WLAN Mini Card in step II.15. the guide when you use this driver).

  I uninstalled and reinstalled Firefox, deleted the entire folder profiles and reset Firefox. I see that the older (orphans) article points to my router. However, I have a new router and have updated their software. There is no button to add an exception (as stated in the article), so I can't just work around it. This problem does not occur with IE, so I have a hard time to believe that it is my router.

  How to solve this problem? I really want to change browser.

  Finally, I tracked the issue. The answer was found here:

  It turns out that Avast has a web shield that passes through its own verification of certificate https. Of course, this feature is not quite right and loses track of the certificates. Disable "https scanning" in the settings of Avast resolved the problem.

• Connection problem Internet accounts

  Hello, I am currently using MBP 13' early 2015.

  After that I updated OS X 10.11.4 to 10.11.5, many problems has produced, including chrome and safari closed the problem that often needs force to restart the mac.

  Today I "noticed" my calendar a major problem. It was linked to my google account and cannot sync more. So I got out my google account in preferences and tried to re-login. Even if I tried more than 30 times, I can't log in to my account. The situation is exactly the same in fowllowing link:http://apple.stackexchange.com/questions/218098/cant-add-google-account-to-osx

  I tried a few prescriptions: delete some files (related to the google account) in the keychain, try to connect in safe mode, restart the mac, etc. Nothing has been useful.

  After 3 hours, I also found other accounts have the same problem: once I log in, I can't log in again. More google reader shows another problem-sometimes I can not connect and it disconnected after the mac is restarted.

  I think that my macbook has a problem on his ring or accounts on the Internet but I have no idea how to solve this problem.

  Is there someone who has the same problem? Any solution?

• Strange internet connectivity problem

  Hello!

  I'm having a connectivity problem I have never met before. I use a wireless router from Apple with internet cable.

  Yesterday, my computer would be is no longer in contact with my router wi - fi. I get a message that the network could not be attached (I ran the Diagnostics wireless, but it's a whole lot of sense to me empty files). However, I also have a Roku, and which IS connected to the WiFi without problem. I completely stopped and restarted the computer, no joy. Reset the modem and the router, no joy. Still works with Roku, not with the computer. But the weird part is, I have Optimum Online, which allows subscribers to log-in to its hotspots, and it worked! I am connected Optimum wi - fi network on my computer right now.

  So I don't know where is the problem! It is not the router, because this is related work with Roku and is not the computer, because it is connected and working with the Optimum hotspot. What gives?

  Try this!

  Go to the Apple menu > System Preferences > network

  Select a Wi - Fi connection in the sidebar and then click on the button "Advanced...". "in the lower right corner of the screen

  In the list of preferred networks, delete the name of your Wi - Fi network

  Click on the "OK" button to save that change and then 'apply' in the network preferences window.

  Now, go to the Applications folder > utilities > Keychain Access

  Make sure that "Login" keychain is selected and "All items" in the category is selected in the sidebar

  Use the search field to find items that Keychain with the name of your Wi - Fi network and remove

  Quit Keychain Access

  Now try and access your Wi - Fi network
