iPhone 15 WiFi Not Working? 10 Fixes

⏱ 5–10 min 🔧 Difficulty: Easy ✅ Works on all models

iPhone 15 won't connect to WiFi, keeps dropping, or shows no internet? Here's how to fix it step by step.

Settings → WiFi → toggle off, wait 10 seconds, toggle back on. Simple but fixes ~30% of cases.

Settings → WiFi → tap (i) next to your network → Forget This Network. Then reconnect and enter your password.

Power off fully (volume + side button), wait 30 sec, power back on. WiFi radio resets during a full reboot.

Test other devices on the same network. If they also have issues, restart your router (unplug 30 sec).

Settings → Cellular → WiFi Assist (scroll to bottom). Turning this off prevents the phone from switching to cellular when WiFi is weak.

Settings → WiFi → tap (i) → Configure DNS → Manual → add 1.1.1.1 and 1.0.0.1. Cloudflare DNS often resolves connectivity issues.

Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings. You'll need to re-enter all WiFi passwords.

Settings → General → About. If a carrier update is available, a prompt will appear. Install it.

Settings → General → Software Update. WiFi bugs are patched regularly.

The iPhone 15 supports both bands. Try connecting explicitly to the 2.4GHz network (usually labeled with _2G or _2.4G). It has better range.
