There is not any clear-cut solution, so you should try on all applicable workarounds until a permanent method is helpful. Remember to check your Internet connection to know if the problem is already fixed or not.

First method: Reboot the wireless router.

You should start with the Internet connection. While the problem only happened after you updated your iPhone, it’s imperative to get rid of firmware crashes on the network equipment if other devices are also experiencing the same symptoms. Similar to other devices, modems and routers sometimes occur firmware crashes and once it happens, symptoms will be triggered. The easiest but most effective solution to such a problem is restarting it. To do so:

  1. Press the Power button of the wireless router/modem to power it down.
  2. While it is turned off, unplug its adapter from the power source and leave it for about 1 minute.
  3. After that, plug it back in and power the router/modem on again.

After you reboot the wireless router/modem, you should then restart your iPhone XS to remove junk files and caches in your phone internal storage.

Second Method: Disable/Re-enable Wi-Fi

Disabling Wi-Fi for a few seconds and then turning it back on is another simple trick, but effective to fix random Wi-Fi disconnection issue on your iPhone XS after the latest iOS update.  It works by quickly refreshing the wireless functions of your phone, along with removing random Internet glitches. Here are a few ways to get it done:

You can also use the Airplane mode trick to fix the issue. To do so:

  • Navigate to Settings > Airplane Mode menu
  • Toggle the switch to toggle it on. This will then disable all wireless radio functions, including Wi-Fi
  • Now, restart your iPhone XS while the Airplane Mode is still enabled.
  • Once your phone reboots, return to Settings-> Airplane mode menu and tap on the switch again to toggle Airplane mode OFF.
  • After that, reconnect your iPhone to the Wi-Fi network and check if the Wi-Fi connection is already stable.

Third solution: Forget Wi-Fi network and reconnect to it

  • Tap on Wi-Fi.
  • Enable Wi-Fi, if necessary.
  • Find and choose your Wi-Fi network from the list of the available Wi-Fi networks
  • Tap on the “i” icon next to the name of the network.

  • When prompted, tap on Forget network to confirm your choice
