Problem 1: I updated my 5s to 8.1.2 two days ago. Since the update, my Wi-Fi speed has been consistently at about 1/3 of what they were prior to the update. Additionally, my signal strength has severely deteriorated.
Many people complain that the release of iOS 8.1.2 is really a disaster for them. Because after updating to the latest version they have a Wi-Fi connectivity problem, which include not being able to connect to a Wi-Fi network, dropping connection intermittently and speeds being extremely slow. In order to help those who have the same issue to get out of the trouble, I introduce 5 workable solutions to fix Wi-Fi connectivity problems. Most of them are come up by the heart-hot net friends. If you are faced up with the problem please take a few minutes to read it. Hope to help you well. The details are as follows:
Solution 1: Get the Network Settings reset
This is a most common way to solve network connectivity issues. So you should have a try with it firstly. To reset network settings, open the Settings app and navigate to Settings > General > Reset and tap on Reset Network Settings.
Solution 2: Disable Wi-Fi Networking Services
Please choose according to the following order:
Settings >Privacy > Location Services > System Services, and then disable the Wi-Fi Networking services
Note: This only relates to your location being used for Wi-Fi Networking, so it doesn’t disable Wi-Fi entirely.
Solution 3: Set Custom DNS
Sometimes your ISPs DNS servers may have a problem. In this case you can switch the ISPs DNS to Google DNS or OpenDNS. You can refer to this guide: How to Change DNS on iPhone/iPad
Solution 4: Restore and Setup as New iPhone/iPad
If the solutions above don’t work you can restore your iPhone/iPad with iTunes. This way can get rid of possibly problematic customizations and settings on your device. Here is a guide for you: How to Restore Your iPhone/iPad with iTunes
Solution 5: Downgrade iOS 8.1.2 to iOS 8.1.1
This is the last life-saving straw to keep you out of the trouble. If you can’t think of another option to deal with the problem you’d better to continue with this method. Here is how to:
Step 1: First download iOS 8.1.1 firmware file for your iPhone, iPad or iPod Touch.
Step 2: Connect your iOS device (running under iOS 8.1.2) to computer.
Step 3: Open iTunes from your computer and select your Apple device from the top right corner.
Step 4: Hold the Alt/Option key (Mac) or Shift key (Windows) on your keyboard and choose the check for update option. Actually it was a restore method. So don’t forget to take a backup.
Step 5: Select .ipsw file which is already downloaded. iTunes will show you a message to update your iOS device to iOS 8.1.1.
Step 6: Choose Update option. iTunes should now downgrade your iPhone, iPad or iPod touch to iOS 8.1.1.
After downgrading, your iOS device will restart. Now you should see “Slide to upgrade”. Just enter the passcode and wait sometimes for the downgrade process to complete.
1. You can only downgrade your iOS device to iOS 8.1.1.
2. Before doing any downgrading process, first back up your iOS device. If you forgot the password to the backup files you can use iPhone Backup Unlocker to recover it.
3. Apple does not recommend downgrading. So it’s your own risk
As I’m concerned, that is the top 5 solutions to fix Wi-Fi connectivity problems on iOS 8.1.2. If you have other better ways or any suggestions to work out the trouble please don’t hesitate to post it under the comment. Thank you!
