IOS 13.3. 1 includes bug fixes and improvements. This update:
……
It solves the problem that the notification may not be pushed through the wireless local area network (Wi-Fi).
……
1. restart (I know some people really haven't restarted themselves)
Restart iPhone.
2. Upgrade the system to the latest version.
(Especially the XS/XR/ 1 1 series, Apple optimizes the signal of Intel baseband almost every time it updates. )
2. If Wi-Fi is common:
To set-wireless local area network (Wi-Fi)-exclamation point to the right of Wi-Fi name-set DNS.
Delete your own DNS and replace it with any of these groups (or choose two of them to mix):
( 1) 1 19.29.29.29, 182.254. 1 16. 1 16
(2) 223.5.5.5 , 223.6.6.6
3. If it is 4G, it is more common:
It is recommended to take out the SIM card and wipe it with an eraser.
Remove the SIM card from the iPhone or iPad.
Or take your ID card to the business hall to get a new SIM card (which may solve the problem that "Welcome to China Mobile/Unicom" pops up frequently).
I personally understand that some batches of SIM cards may really be incompatible with intel baseband. )
If it only appears in the place where the signal is bad, please actively complain to the three-person customer service about the signal problem (if possible, bring noble users with a few months' phone bill).
4. If both 4G and Wi-Fi often have problems,
(1) Remove WeChat, restart and reinstall.
(2) If not, go to Settings-General-Restore (bottom)-Restore network settings.
5. If 4 still doesn't work, please restore-restore all settings after backing up important data (it should be "Erase all contents and settings" in the first line, not in the second line).
Restore the iPhone settings to the default state.
6. If 5 doesn't work, find a computer in recovery mode and refresh it without retaining all data.
