If your iPhone 7 connects to Wi-Fi but then drops the connection shortly after—switching back to LTE or showing no internet—you’re not alone.
This is a common (but fixable) issue. Here’s a step-by-step guide to get your iPhone 7 staying connected to Wi-Fi properly again.
Problem Summary
The Issue:
- iPhone 7 connects briefly to Wi-Fi, then disconnects.
- Other devices stay connected without issues.
- Resetting the router doesn’t seem to help.
- Problem happens across multiple Wi-Fi networks.
Good news:
This suggests the issue is with your iPhone, not your home internet.
Things to Check First
- Make sure your iPhone 7 is updated to the latest iOS version.
(Settings > General > Software Update) - Check if the Wi-Fi network itself is stable by testing other devices (like laptops or tablets).
How to Fix iPhone 7 Wi-Fi Disconnect Issues
1. Restart Both Your Router and Your iPhone
Simple but effective:
- Unplug your router for about 30 seconds and plug it back in.
- Restart your iPhone by holding the Power button and sliding to power off.
2. Forget and Reconnect to Wi-Fi
Clear any connection glitches by forgetting the Wi-Fi network and reconnecting.
Steps:
- Settings > Wi-Fi.
- Tap the (i) next to your Wi-Fi network.
- Tap Forget This Network.
- Reconnect by entering your Wi-Fi password again.
3. Reset Network Settings
If the issue persists, reset your network settings.
Steps:
- Settings > General > Reset > Reset Network Settings.
- Your Wi-Fi passwords will be erased, so make sure you know them beforehand.
4. Test with Other Wi-Fi Networks
- Try connecting your iPhone to Wi-Fi at a coffee shop, a friend’s house, or another hotspot.
- If the issue only happens at one location, the problem might be with that router.
- If the problem happens everywhere, it’s definitely the iPhone.
5. Restore Your iPhone As New (Only If Necessary)
If nothing else works, restoring your iPhone may solve deep software glitches.
Important:
- Backup your iPhone first.
- Go to Settings > General > Reset > Erase All Content and Settings.
- Set up your iPhone as new—do not restore from a backup yet.
- Test Wi-Fi stability before reinstalling apps.
If Wi-Fi Still Doesn’t Work…
At this point, it’s time to contact Apple Support.
There could be a hardware issue with your iPhone’s Wi-Fi antenna.
Quick Tip
If your iPhone automatically jumps to LTE instead of staying on Wi-Fi, try turning off Wi-Fi Assist:
- Go to Settings > Cellular.
- Scroll all the way down.
- Turn Wi-Fi Assist off.
Hi, i recently bought iPhone 7. Previous I was using samsung galaxy s3. I noticed that my iphone will not stay connected to my college hostel wifi which requires login (username & password) to college network page. I did not encounter this problem when i was using android previously. Every time i login, it only connects to the wifi for a short period of time before it switches to mobile data. And i had to repeat the whole process multiple times in a day which is very annoying. When i go back home, it stay connected to the wifi just fine. I tried asking the IT dept to reset the hostel router, but the problem persists.
Hi I recently got a new iPhone 7. I seem to have intermitted WIFI connection. I have tried to reset the settings in my General Settings. No Luck.
It seems to disconnect from the WIFI when I put my phone down and it goes into sleep mode. This if very frustrating. I hope you can help me with a solution.
