• Why is my MacBook Pro cut wifi connection?

  In recent weeks, my wifi connection has often declined, and I have to restart my MacBook Pro to have the wifi connection.

  I have a MacBook Pro 13 inch (end of 2011) and am running OS X El Capitan 10.11.4 version

  I brought my computer to a Genius Bar, and someone had to watch. The guy helped me clean up my caches and adware which helped. It also helped me with existing Wifi preferences of trash again.

  My computer worked fine after my visit to the Genius Bar and now almost a day later my wifi connection dropped again and I had to reboot my computer.

  Any suggestions on what I should do?

  Maybe corrupt network preferences.

  Open the Finder. In the Finder menu bar, click go > go to folder

  Type or copy paste the following text:

  / Library/Preferences/SystemConfiguration

  Click OK, and then move all files in the SystemConfiguration folder to the trash.

  Restart your Mac. See if that makes a difference.

  Your Mac will generate a new SystemConfiguration folder for you.

• HP Deskjet 3055 has the Macbook Air without wifi connection

  To make the HP Deskjet 3055 has for my son for the University.  They use an Ethernet connection over wifi and so it would probably be to connect your Mac to the printer using the USB cable instead. What sounds right and I have reason to think that cable he would need is included in the box of the printer?

  Hello

  That is right.  The printer does support wireless or USB and not wired Ethernet.  The cable comes in the box.

• HP Officejet 6700 Premium suddenly does not connect to my Macbook Pro more

  Hey everybody,

  I got my HP Officejet for over a year and it has always worked perfectly. It has a stable wifi connection. Yesterday, all of a sudden the printer did not respond, so I asked my brother, who is the type of an It'er and removed the printer from the "Print & Scan" system preferences. Now, however, it will not be added more. As I said, it doesn't have a stable wifi connection, and I can see the presence of the printer when I click on the plus to add a printer, but then, if I want to add it, it says "cannot communicate with the printer at this time." I rebooted the computer laptop and printer and even left stop for the night, but it does not work. Nobody knows anything else to try?

  Thank you very much in advance

  Turn on router wait 5 min and turn on the printer and the computer.

  Check the printer if the Wifi is STRONG.

  Open Preferences system, Print and or print and scan pane. If you see the printer listed
  Click Printer button remove. It will ask for confirmation to delete printer.
  Click on add it or + button, select the MFP Hello not Fax. Adding that should update the drivers.

  If the Wifi of the printer is not fixed, you will need to reconfigure.

  Hello

  Before you begin to uninstall or reinstall some Toshiba firmware, I would like to know what Satellite L550D-xxx you exactly.

  The point is that different L550D models were equipped with a different wireless network cards.
  Not quite sure if your have a Realtek Wlan card. It looks like a Realtek LAN card.

  However, you must first check if the wireless network card is recognized correctly in the Device Manager.
  In the Manager of peripheral devices, network cards, you should see LAN and WLan card.
  In the case where the card WLan display correctly (no yellow exclamation) WLan driver installation is not necessary.

  In this case, you should go to the next step: check if you can enable / disable the wireless network adapter using the FN + F8 key combination.
  Where this is not possible, check if other keys FN function.
  Where other keys FN don t work, you must reinstall the software mentioned (Toshiba Value Package added, Flash cards).

  This can be done in the control panel-> programs & features
  After that the two software can be removed, clean the system using CCLeaner.
  Now, you can check the EU Toshiba driver page http://www.toshiba.eu/innovation/download_drivers_bios.jsp to download the software deleted.
  Installation is easy; Unzip the package and run the installation exe file

  Then you should be able to use the FN + F8
  After that the WiFi network has been successfully activated, go to the network & sharing Center-> manage wireless (left) and click Add to configure the new wireless network

  I would be grateful if you can provide us with the following information to help us better understand the issue.

  1. Are you able to connect any other wireless device to the same network?
  2. Are all the lights on the Modem/Router Green?
  3. Have you tried to connect your HP laptop with wired network? If so, was the same result?

  Problem with the random disconnection of a wireless network can be triggered for a variety of reasons. To find out the exact cause of the issue, I would recommend that you run the network troubleshooter utility.

  Network convenience stores

  This problem can occur if authentication enable IEEE 802. 1 X for this network checkbox is enabled. If this box is checked, but there is no server to authenticate the connection is interrupted. If you turn on the wireless network connection, it disconnects again after a short period.
   
  Method 1: Disable IEEE 802 authentication. 1 X

  To disable authentication IEEE 802. 1 X, follow these steps:

  • Click Start, type ncpa.cpl, and then press ENTER.
  • Right click on your wireless network connection and then click Properties.
  • Click the wireless networks tab.
  • Under preferred networks, click your wireless network, and then click Properties.
  • Click on the Authentication tab, click to clear the authentication enable IEEE 802. 1 X for this network
  • Check box, and then click OK twice.

  Method 2: Disable the IP assistance service

  • Hold down the Windows key and type R, type "services.msc" (without the quotes) and press enter
  • Scroll down to the IP assistance service, right-click on it and select Properties
  • In the drop-down list box that says "Automatic" or "Manual", set it to disabled and then click 'apply '.
  • Then click on "Stop" to stop the service from running in the current session
  • Click OK to exit the dialog box.

  Method 3: update the Firmware on the router

  Download and install the latest firmware for the router, in case the steps above fail to resolve the problem. If your router is Netgear, then you can follow the steps below.

  NET gear 3700 firmware update

  Hope it would help. If problem persists always post back with the current state of your computer and the result of the proposed suggestion, we will be happy to help you.

• Suddenly stopped to receive emails on MacBook Pro, but continues to receive via iPad and iPhone

  I have a 2015 MacBook Pro retina with OS X Yosemite and email via cableone.net. The laptop suddenly stopped to receive new e-mail messages. I can send emails from her, but not receive. I have not changed my settings. I still get e-mails via my iPhone and iPad. Cableone could not help and said to contact Apple. Anyone know what can cause this and how to fix it? Thank you.

  Can remove you the account and then restart the Mac and then add him back?

• WiFi connected but browsers and mail stop working

  Here's the situation:

  iMac, 4 years, OS X 10.7.5

  WiFi connected but, browsers and mail stop working sometimes recently.

  Checked the wifi & browser settings.

  Do not remember something like what happens when connected online cat5.

  Curious to know what is happening.

  Say local store card is perhaps go wrong.

  The machine is only 8 ' of router.

  Another pc on the network does not appear to be a problem.

  Any help appreciated.

  You can connect an Ethernet cable to see if it works on Ethernet when you encounter problems easily?

  Try to use your own DNS server.  Because if the DNS server that you use currently is not translate www.company.com name to IP address nn.nn.nn.nn, it will look like you do not have internet access.

  System Preferences-> network-> advanced-> DNS-> [+]

  OpenDNS.org

  208.67.222.222

  208.67.220.220

  Google DNS

  8.8.8.8

  8.8.4.4

  You can remove them later if you want using the [---] button.

  If this does not work, it could mean that your router is having problems.  Most routers act as the local DNS server, make a cache and especially fair bet as a DNS server provided a front for the access provider.  If the router begins to act, it can often be cleared by power cycling the router.

  And once again, if you provide your own DNS server works, then it could be DNS servers of the ISP, but less likely that they would be getting a lot of complaints from their customers (assuming that customers thought it was DNS servers).

  You know, there are 2 sides to any path of communications.

  If it is technically possible for radio Wi - Fi of the iMac to fail, it's actually not very common.

• DX2 - suddenly affected by problems of WIFI connectivity

  Suddenly, I have WIFI connectivity problems on my DX2. The phone previously connected without any problem to my router which is secured by WPA/WPA2 PSK.

  What is happening is this: the phone scans all the available wifi networks, search my router and trying to connect to it for about 10 seconds. then quit and re - start the search. While he tries (unsuccessfully) to connect to my router, it reads 'obtaining IP address. "

  I'm on Android 2.3.3. and really doesn't have this problem right after the Gingerbread update.

  Thoughts are appreciated.

  Problem solved. Turns, the fix was as easy as re-booting of the wireless router, but I didn't go to this subject until my wife started to complain that she can't go on the internet with her laptop.

  Hello Pierrette45,

  Thank you for using communities Support from Apple!

  Leave your post, it looks like you have a problem with your wireless keyboard does not. I also understand that you have completed a ton of fun troubleshooting. One thing I would look for in this situation is a potential cause of the interference of the signal as described in the following article.

  our mouse or keyboard intermittently not responding

  Follow these steps if your mouse or your keyboard sometimes stops responding temporarily.

  Click or press a key

  • Click on the mouse or trackpad, or press a key on the keyboard to reconnect the device to the computer. It may take a while for the device to respond.

  Search for interference of signals

  • Wireless networks that operate on 2.4 GHz can cause interference. Move base stations of phone wireless, microwave ovens and other appliances of 2.4 GHz far your Mac if you suspect interference.
  • Keep devices wireless to 10 meters (30 feet) of your Mac.
  • Avoid putting metal objects between your wireless device and your Mac.
