  What do you mean that you need to get your SIM card fixed? It sounds like one of two things that cause you problems, either there is a problem with your SIM, or you need to troubleshoot your phone. Have what troubleshooting you tried? You don't list everything, and if you suffer from this problem since iOS 8, I would ask why you do not have the home phone? Who provides a service for your device, Apple, an Apple authorized service provider or your carrier?

• 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

  Hey @Roberto_ITALY,

  Thanks for posting in the Forum from HP Support.

  I understand that you are unable to claim your HP Color LaserJet Pro MFP M177fw in your account ePrint Center due to a connection problem.  I would like to help.

  I don't see this particular error with password resets from time to time.  I have a workaround that can clear up this place for you:

  • Click here.  This will bring you to <www.snapfish.com >.  As the Snapfish site is linked directly with ePrint Center and HP connected, you can try to reset your password as follows - click the connection icon and then "forgot your password":

  

  • Enter the e-mail address that you use to connect to the ePrint Center and click on submit.
  • You should receive a message of automatic reset of password by email - the reset as expected before and then try to use this new password to Snapfish to connect downtown ePrint.
  • If this does not solve your problem of access ePrint Center, please call our Cloud Services to 855-785-2777. If you do not live in the United States / Canada region, please click the link below to get help from your region number.

• Officejet 4500g510g connection problem

  The printer constantly alternates of connected and disconnected as displayed on the HP Solution Center does not allow me to fax or scan but allows me to print

  Hello VinhLong,

  When you connect a device to a router router assigns the device an IP address. There are two types of these assignments. You have a dynamic IP or static IP address.

  A dynamic IP address can change and is automatically assigned by the router. Whenever you reboot your computer, printer, etc., the router can assign the unit a new IP if for some reason he can't use it. This is the default setting and is what most people use.

  An IP address is an address that you essentially hard-code in the router which tells the router whenever this device connects to the network assign this IP address. Using the static IP address performance and connectivity is generally improved.

  Since you have a connection problem, we should see if we can stabilize the connection hard coding a static IP address on the router and the printer to the printer to use when connected to the router.

  Information about setting up a static IP address were taken from this article for troubleshooting HP.

  The "Printer not found" error message during the Installation of wired (Ethernet) network in Windows XP and Windows Vista

  The article is not completely relate to your problem, but we use it to capture the static IP address instructions.

  The DHCP Dynamic Host Configuration Protocol () service provided by the router can change the Internet Protocol (IP) address on the HP product, which interferes with the network installation. An IP address uniquely identifies the product over the network.

  Follow these steps to assign an IP address does not change to the product by the built-in webserver (EWS).

• Two wifi routers EA6200 having connection problems.

  I had a single wifi router configuration EA6200 and it was working fine but it has not reached the corner of my house. I decided to buy a second EA6200 in an attempt to expand coverage wifi and nothing else that problems have had since then. I tried several configurations and there are always questions where wifi is either very slow or cut all together. I tried to configure the routers by using the options listed in the manual. We'll call it the router connected directly to the modem ROUTER1 and ROUTER2 upstairs router.

  I connect both routers via a power adapter line I used for a while since I rent and can't pass the cables through the walls. I have one of the LAN ports on ROUTER1 connected to port WAN on ROUTER2 and ROUTER2 clipping value. I tried with ROUTER2 get his address IP of ROUTER1 automatically and I also tried to set a static IP address on ROUTER2, but I always had connection problems. I also tried one of the LAN ports on ROUTER1 connecting to one of the LAN on ROUTER2 ports. I put a static IP address on ROUTER2 and disabled DHCP. For both configurations, I tried to have the same SSID and password for both routers so that I can roam and connect automatically to the strongest signal and at first I put the automatic channel selection. I still had problems connecting so I tried to change the SSID of the router and change the SSID for the bands of 2.4 and 5 GHz and I tried to adjust the channels myself no conflicting channels and I still have problems.

  Again, the problems I encounter are failure intermittent wifi where it disconnected completely from the wifi but will reconnect then slow connection speeds not long after but also intermittent. Also, I have several chromecast dongles on the TVs in my house and they also periodically lose the connection to the network and have a lot of buffering issues. These problems disappear with a single connected router. I also tried to reset both routers and disconnect and plug my modem at the factory.

  All the ideas, because I don't see anything else to try?

  Bilz says:

  If I understand you correctly I tried already. I connected the LAN to LAN and used the static IP you listed for the second router. I put the SSID for the 5 GHz band were the same for both routers and used a different SSID for 2.4 GHz bands, but it's still the same on both routers. I used the Wifi Analyzer app to determine the best channels for my router and I put them all channels different worms. I don't know if I used specifically 1, 6 or 11, however. It would make a difference? For example if I used chanells 4 and 6 for 2.4 GHz bands, do you think that this would have caused some of my questions?

  Not quite. All SSIDs 4 must be different. You can be the cause of the camera jump back using the same ssid. So it could be xxxxx_24p and xxxxx_24s and even for the 5 GHz. xxxxx_5p and xxxxx_5s

• Home wireless network connection problems

  What should I do if I normally connect to the wireless network does not appear?  It is not a network card problem, because I can connect to other wireless and school and other places.  I tried to reset the router, ping and by unplugging and seeing what I could understand on the computer at home, but nothing does.  Any ideas or suggestions would be greatly appreciated.

  Thank you.

  Hello

  Have you tried other computers to connect to your router? You use both wire and wireless
  connection?

  Unplug the modem and Router 3 + minutes. And then reconnect the modem - when it is running
  Plug in the router - when it is running - restart the computer. This is known as a hard reset.

  Check with your router manufacturer support.
