What causes Wi-Fi problems to occur on your iPhone 7 Plus?

Wi-Fi problems in mobile devices are triggered by a number of factors. But more often the underlying cause is on the network service provider’s end like outages, network system downtime and other technical problems. Things like this can happen without you even knowing so you really don’t know when your Internet got cut off by what. Aside from a problem on the side of your Internet Service Provider (ISP), there also other factors that can cause disruptions to mobile Wi-Fi connectivity. And these are as follow:

Faulty network equipment

Your home network typically begins with a network equipment. That is the very source of your Internet at home. Having said that, you should start troubleshooting with your wireless router or modem when all of a sudden you cannot connect to Wi-Fi on your iPhone 7 Plus through your home network. Note that Wi-Fi router/modem firmware can also get corrupted or the device itself can be damaged. And should that happens, the rest of all connected devices will likewise have trouble with connectivity.

Account problems

Other cases of Wi-Fi problems are associated with account problems. Some carriers typically impose a soft disconnect to accounts with unsettled issues. When this happens, outgoing services like calls, texts, and Internet browsing are temporarily unavailable. Services will only resume once the main issue is settled. And that denotes the need for you to contact your carrier to verify your account status and settle whatever there is that needs to be settled.

Incorrect settings

Sometimes the root cause is on the network settings on your device. If your other devices in the same network are able to connect to Wi-Fi but your iPhone 7 won’t, then most likely it’s on your phone’s network settings. You might have disabled certain option that needs to be enabled or vice versa.

Faulty updates

Software updates can also cause disruptions to your iPhone’s wireless Internet especially if they contain some bugs. Other bad updates can even messed the current network configurations on your device, which then results to no Wi-Fi access.

Hardware damage

The worst among the possible causes is a hardware damage. Physical or liquid damage is most likely to blame especially if the problem started after you accidentally dropped or got your iPhone wet. Often times, it’s the Wi-Fi antenna or other relevant component that gets busted. Unfortunately, there is nothing much you can do on your end in this case as your iPhone already requires tech service for hardware fixing.

If you are certain that the problem is not associated with any sort of damage to your iPhone hardware, then you can try performing some workarounds to troubleshoot software problems that might have inflicted problems to your iPhone 7 Plus wireless connectivity. To further assist you in this concern, I have listed some potential solutions for you to try on.

 

Recommended solutions to deal with wireless connectivity issues on iPhone 7 Plus

Highlighted below are generic solutions to Wi-Fi problems on your iPhone 7 Plus. If possible, try to determine the possible cause so as to save time and effort in doing unnecessary workarounds. Try to think of what has happened before the problem started. For example, did you suddenly lose access to Wi-Fi after installing a new app, changing some settings, or installing iOS update? Most likely the problem has something to do with the prior actions done on your phone. However if it’s just too hard for you to determine the probable cause, then you may go ahead and try all applicable workarounds and then test your device to see if that will fix the problem.

Before you proceed, care to check your account and network status. If the problem happens to be inflicted by an account issue or network outages, then you don’t have to perform any troubleshooting. All you have to do is contact your carrier or Internet service provider to verify your network and account status. If everything is good with your account and your network provider’s end but still you don’t have Wi-Fi access on your iPhone 7 Plus, try the following solutions.

Reboot network equipment

Start from the very source of your Wi-Fi network — the wireless router or modem. A simple restart or power cycle on the network equipment might be the only thing you need to fix your Wi-Fi problem at home. Should the problem be triggered by firmware glitches on the wireless router or modem in use, a reboot will fix it. Here’s how it’s supposedly done:

  1. Power off your wireless router or modem. Locate the Power button then press that button until the device turns off.
  2. While the network device is powered off, unplug it from the power source and leave it unplugged for about 30 seconds.
  3. After the elapsed time, plug it back into power.
  4. Press the Power button again to turn it on.

Wait until all its lights become stable. Lights should all be green or yellow. If any of the light indicators shows red, it means something is wrong. For example, if the signal indicator shows a red light, it means that your network device is getting no signal from the network thus it won’t be able to feed Wi-Fi signal to any of your device within the network.

If you notice something unusual on your network equipment, contact the manufacturer for further assistance in troubleshooting the wireless router or modem. Once the problem is fixed, your Wi-Fi connection should be up and running again.

Reboot your iPhone 7 Plus

If the problem is triggered by software glitches on the iPhone system, then a restart might be able to help. Minor flaws affecting a device’s network functions is often remedied by a reboot also known as soft reset. So if you haven’t already, follow these steps to perform a soft reset on your iPhone 7 Plus:

  1. Press and hold the Side button or Power button until the Slide to Power off screen appears.
  2. Drag the slider to turn off your iPhone completely.
  3. Wait for about 30 seconds, then press the Power button again until the Apple logo appears and the device power cycles.

After the reboot, try to open your browser app then navigate to a website. If you can access the website without bumping into any error prompts or codes, then your Wi-Fi is working fine now.

Check or configure network settings

Settings that are not configured correctly can also cause your device to lose access to Wi-Fi. To make sure this is not what’s causing your trouble, verify and ensure that everything is setup correctly. Among the settings you need to look into are Airplane mode. It has to be disabled in this case. Wi-Fi must be turned on.

  1. To check and confirm, head over to Settings-> Airplane mode then toggle the switch to turn the feature on and then OFF again.
  2. To verify if Wi-Fi is enabled, go to Settings-> Wi-Fi, then toggle the Wi-Fi switch to turn Wi-Fi off and then back ON to enable Wi-Fi.

If you’ve done that and the problem persists try these workarounds:

Forget wireless network and reconnect

This will erase all your current wireless network settings, server settings, network SSIDs and passwords. Doing so help rectify any conflict on any of the registered wireless networks on the phone. Here’s how it’s done:

  1. Tap Settings from Home.
  2. Tap Wi-Fi.
  3. Tap the information (i) icon next to the Wi-Fi network that you want to forget.
  4. Tap Forget This Network.
  5. Tap Forget to confirm.
  6. Restart your iPhone afterwards then setup your wireless network again. See if that fixes the problem.

Reset network settings

If forgetting the network failed to give you a remedy, then try performing a network settings reset instead. Doing so resets your current network settings back to defaults thus eliminates any incorrect options and network configurations. You may need to take note of your Wi-Fi passwords beforehand because these will also be deleted along with other network information. Once you’re all set, follow these steps:

  1. Tap Settings from Home.
  2. Tap General.
  3. Tap Reset.
  4. Tap Reset Network Settings.

Wait until the network settings reset is complete. Once it’s finished, your device restarts. Set up your Wi-Fi network on your iPhone 7 Plus again and then try to see if you are now able to connect or access wireless Internet on your phone.

Remove and re-insert SIM card

Other network issues have been associated with a faulty SIM card in use. Usually you’ll be prompted with SIM card errors in this case. To rule this out from the possible causes, removing and reinserting the SIM card can help. Here’s how it is supposedly done:

  1. Power off your iPhone completely.
  2. Use the SIM ejector tool or a small paper clip that is straightened.
  3. Locate the SIM tray on the right side of your phone.
  4. Insert the ejector or paper clip into the small hole and then push it slightly until the SIM tray pops out.
  5. Remove the SIM card from the tray then check for any visible signs of damages like scratches or dents. If there’s none, insert the SIM card back into the tray.
  6. Reinsert the SIM tray into the iPhone.

Turn your iPhone back on and then try to see if Wi-Fi is already working fine on your device.

Restore your iPhone 7 Plus

A system restore is often needed to deal with complex issues on the iPhone software. If none of the prior methods is able to fix your Wi-Fi problem, then most likely you are dealing with a complex software issue. In this case, your best hope to fix the problem is a system restore. You may opt to try a factory reset or DFU mode restore on your iPhone 7 Plus. But before doing so, don’t forget to backup your iPhone to iCloud or iTunes for safekeeping. Both of these resets will wipe your device completely thus eliminate any bugs and bad segments that might have triggered the problem on your iPhone’s Wi-Fi functions. Refer to the following steps on how each of these resets are carried out.

Factory reset (through Settings menu):

  1. Tap Settings from the Home screen.
  2. Tap General.
  3. Tap Reset.
  4. Select Erase All Content and Settings.
  5. If prompted, enter your passcode.
  6. Confirm selection.

You can also perform a factory reset through iTunes. You will need to connect your iPhone 7 Plus to a computer using the supplied USB or Lightning cable then open iTunes. Wait until iTunes recognizes your device then follow the screen instructions to factory reset your iPhone.

Your other reset option is a DFU mode restore. A DFU mode restore is a deepest type of system restore on your iPhone. It puts your iPhone in the state where it is still able to communicate with iTunes on a computer without activating the boot loader or iOS. But there are some risks that you need to consider. A DFU mode restore can possibly cause your iPhone to brick especially when the process gets interrupted or not successfully completed. Thus a DFU mode restore should not be done if the phone is liquid-damaged. There is a tendency that the device won’t get to finish the process because of the damaged component and when that happens the system can brick. If you’re willing to take the risks, then you may opt to go for it. A detailed instruction on how to perform a DFU Mode restore on iPhone 7 Plus is available on our troubleshooting page. Feel free to visit that page if necessary.
