Problem 1:  iPhone 8 Plus can’t connect to two wifi networks only

Hi! I have a brand new iPhone 8 plus and couldn’t connect to wifi today at the gym I work at or my daughter’s piano lesson place. At BOTH places I could connect to on my old iPhone through wifi today. Â I just got my new iphone on Sat. Â It WILL connect at home and at my brother-in-law’s house. Â What is wrong? Â I know the wifi was working both places today because I was able to get on with my other devices. Â I clicked on the blue “i” in the circle and tried to even input the information in the fields that I saw on my other device in hopes it would attach. Â It looked like to would go, then just sat and spun a wheel without a check mark FOREVER. Â Won’t attach. Â I also switched wifi off and back on. Â Airplane mode was not on. Â Everything appeared fine as I’m use to getting on at other places. Â I do have an iPod touch that REFUSES to attach to wifi some places and will attach in others. Â It makes no sense. Â If this phone is like that I am bringing it back ASAP. Â Please help. — A

Solution: Hi A. Some public wifi networks used by business establishments like hotels, coffee shops, internet cafes, airports, etc., called captive Wi-Fi networks, may use additional security or filters to strengthen regular wifi protection. Such additional security protection can come in a variety of forms. In some networks, an active subscription may be needed in order to access the network. In most cases, a user must first ensure that he or she enters the correct username and password (network login credentials).

Joining a captive network is similar to connecting to any other wifi network. In order to join a captive wifi network or a wifi hotspot that requires an active subscription, you must do the following steps:

  1. Open Settings app.
  2. Tap Wifi.
  3. Tap the network you want to use, then wait for the login screen. Alternatively, you can tap the blue circle with an i” beside the network name then hit Join this Network.
  4. Enter the login credentials. The information that you need can vary depending on how the network is configured. You may have to enter an email address, the usual username and password, and/or acknowledge terms and conditions.

If you still can’t connect to the internet or login to the wifi network successfully after doing the steps above, the best option for you is to talk the wifi administrator. Some network administrators may set the router to block unknown devices by filtering their MAC addresses or IP addresses. Others may allow a device to connect to the network but block internet access. You can still use the network in other ways aside from connecting to the internet. Some routers may have a limited number of users allowed to connect at one time and if that limit is reached, incoming requests to log in may be blocked altogether.

We don’t think this is a device problem at all since you mentioned that your new iPhone 8 can connect to other networks aside from the one at the gym and at your daughter’s piano school. Let the staff of these places take a look at the issue to see if they can help you.

Problem 2: iPhone 8 can’t install Whatsapp app

Can’t install WhatsApp. Couldn’t open the apps like WhatsApp and Google Chrome, then thought i should delete and reinstall WhatsApp and perhaps then it would open. Didn’t help. Followed all the above steps and those didn’t help too! My network is fine. But the apps don’t download on WiFi and my mobile network (both of which is working perfectly fine).

Prior to this, my phone randomly had this horizontal lines across the screen and i constantly had to restart (holding home and sleep/wake button). I went out clubbing and the phone had been working fine until i got home. I switch the phone on and the activate your iPhone screen appeared and every time i reboot my phone, it takes me back to that menu. I’m currently sending this from the iPhone that’s giving trouble. I really need to use WhatsApp for work and social reasons! Please help.

I’m contacting you from Cape Town, South Africa. Both the Apple and WhatsApp server statuses in my country are fine. I’m on iOS 11.1.2. — Storm Solomons

Solution: Hi Storm. We don’t work for Whatsapp Inc. so our knowledge about the product and how to troubleshoot it are taken from online resources as well. In general, almost all Whatsapp problems are connectivity-related so the bulk of your troubleshooting should to check your connection and iPhone settings.

Verify if you can install other apps in your iPhone 8

This is the first obvious troubleshooting step that you must do. If your iPhone 8 is having trouble installing other apps and not just Whatsapp, that tells you that it’s more likely a settings issue and not isolated to the Whatsapp app.

Try to install other apps you haven’t installed before and see if you’ll encounter the same problem. If the issue remains, one of the following must be causing it:

  • you’re not using the right Apple account
  • restrictions is enabled
  • your internet connection is problematic
  • there’s not enough storage space

Use the correct Apple ID. Apps are associated to a particular Apple ID. If you have multiple Apple IDs, make sure that you are signed in to the one you used to install your current set of apps, especially the Whatsapp app. To check what Apple ID is associated with a particular app, do the following steps:

  1. Tap the App Store app.
  2. Tap Updates.
  3. Tap Purchased.
  4. Check to see if the app is listed here. If not, it was likely downloaded with another Apple ID.

Restrictions is enabled. Your iPhone’s operating system can limit installation of apps via Restrictions option. It’s a useful feature for companies that want to prevent installation of additional apps in company-provided devices. To allow your iPhone to install updates, make sure Restrictions for Installing apps is set to OFF. Here’s how:

  1. Tap Settings.
  2. Tap General.
  3. Tap Restrictions.
  4. If prompted, enter your passcode.
  5. In Installing apps option, make sure that the slider is moved to the left. If it’s on the right, it’s enabled and your phone won’t be able to install any app.

Ensure you have good internet connection. Whatsapp regularly need content from its remote servers and if you have a spotty internet connection, either via wifi or mobile data, it may not work as expected. It may also prevent installation of apps as your device will not receive complete installation packages in time. To see if this is causing the current problem, try to connect your phone to a known, stable wifi network and try to install apps again.

Verify you have enough storage space left

If internet connection works fine, you’re using the correct Apple ID, and your phone is permitted to install apps (Restrictions is OFF), then the most likely culprit must be too little storage space left in the device. Although the installation package of Whatapp hovers just below 200MB, it may need more space once installed. In order to prevent installation problems due to insufficient storage, make sure that you have at least 1GB available space left all the time.

Delete Whatsapp via Settings

At this time, we are not aware of any Whatsapp-specific issues that may prevent it from being installed in an iPhone 8. If you continue to experience the same problem after doing all the steps above, you should try to remove it from the system. If you’ve never installed it in the first place, just ignore this step.

To remove an app from your iPhone, follow these steps:

  1. Open Settings app.
  2. Tap General.
  3. Tap iPhone Storage.
  4. Scroll down and look for Whatsapp app in the list below.
  5. Tap Delete app button.
  6. Tap Delete app button again.

Make sure that your phone’s system time and date is correct

Some apps like social networking apps won’t install if the phone has a different date and time discrepancy. To check if your phone sports the right time and date, you can do the following:

  1. Open Settings app.
  2. Tap General.
  3. Tap Date & Time.
  4. Make sure that Set Automatically is ON by setting the slider to the right.

Reset all settings

We don’t know the full history of your device and what changes you’ve tried so far so it’s good if you can try to see what happens if you try the Reset All Settings option. This option will return all settings in your iPhone. It won’t delete any user data like your photos, videos, etc. so it can be done safely.

To do this procedure, follow these steps:

  1. Tap Settings app.
  2. Tap General.
  3. Tap Reset.
  4. Tap Reset All Settings.

Do a full Restore

If all else fails, you can try to factory reset your device and see what happens. Be sure to back your phone up first via iTunes or iCloud or both.

  1. Create a backup of your files. You can do that in a number of ways but the fastest and most effective way is by using iTunes in your PC or Mac. If you don’t want to create a backup at all, you can simply erase everything on the phone by following the steps in this link.
  2. Connect your iPhone to your computer with the cable that came with your phone.
  3. We assume you remember your phone’s passcode so simply enter it when you’re prompted for it.
  4. Select your iPhone once iTunes asks you for the specific device.
  5. Once you’re in the Summary panel or screen, select the option that will restore your device (Restore).
  6. Confirm by clicking on Restore button.
  7. Wait for a few moments while iTunes restores your device to its factory settings. It may also take some time if iTunes will need to install an updated operating system version.
  8. After this factory reset, all software settings should be restored to their defaults.
