Q: iPhone 4s wifi

My iPhone is working 100% fine, and then the wifi just dissapears (but the router and all other devices connected to the router still work) and then if I go into the settings, click 'wifi' the whole phone freezes and the only way I can get it to work is by hard restarting it. Then the wifi will work for a little and soon enough go again. also the network Says "searching" for about 10 minutes and then will say "no service" I've tried hard resetting the phone and taking the sim out and putting it back in but it just does the same thing and says 'searching' before again Saying 'no service'. I've updated to the latest IOS software and the phone should be all okay... Is there any way to fix this or does anyone know the cause of these problems?

iPhone 4S, iOS 9.2.1

    Hi Had3nB,

    The "No Service" error message you are seeing relates to your cellular connection, not your Wi-Fi.  But I will include information here on troubleshooting both Wi-Fi and cellular connections for your iPhone.  

    If you can‘t connect to a cellular network or cellular data

    If you see No Service or Searching 

    If you see No Service or Searching on your device, or can't connect to a cellular network or cellular data, follow these steps: 

    1. Check your coverage area to make sure that you're in an area with cellular network coverage. 
         
      • If you can't connect to a cellular network on your iPhone, make sure that cellular data is on in Settings > Cellular*. On your iPad, go to Settings > Cellular Data.
        •  
      • If you're traveling internationally, make sure that your device is set up for data roaming. Go to Settings > Cellular > Data Roaming.
         
         
         
         
           
    2. Restart your iPhone or iPad.
    3. Check for a Carrier Settings Update.
    4. Take out the SIM card and put it back in. If the SIM card is damaged, or doesn't fit in the SIM tray, contact your carrier.
    5. Reset your Network Settings. Tap Settings > General > Reset > Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you've used before.
    6. If you have another device, see if you can connect your carrier's network with it in that location.
    7. Contact your carrier to: 
         
      • Verify that your account is active and in good standing.
        •  
      • Make sure there are no outages in your area.
        •  
      • Check that your device isn't blocked from receiving cellular services and is set up with the right data plan.
    8. Update your iPhone or iPad to the latest version of iOS.

    If you still can't connect to a cellular network, and have confirmed with your carrier that there isn't an issue with your account or network, try restoring your device.

     

    If your iPhone, iPad, or iPod touch won’t connect to a Wi-Fi network

     

    Take care,
