How to Fix Samsung Galaxy Wi-Fi Not Connecting or Keeps Dropping

Wi-Fi issues on Samsung Galaxy can range from failing to connect, to constantly dropping in and out. Here are the most effective fixes.

Quick Fixes

1. Toggle Wi-Fi off and back on – Pull down the notification shade and tap the Wi-Fi icon twice.
2. Forget and reconnect – Go to Settings → Connections → Wi-Fi, long-press your network → Forget, then reconnect and re-enter the password.
3. Restart both phone and router – Power cycling the router resolves most intermittent Wi-Fi drops.

Advanced Fixes

4. Reset network settings – Go to Settings → General Management → Reset → Reset Network Settings. This resets all Wi-Fi, Bluetooth, and mobile data settings (you'll need to re-enter Wi-Fi passwords).
5. Check IP settings – When connected, tap your Wi-Fi network → advanced settings → change IP from DHCP to Static and manually set an IP address.
6. Disable Wi-Fi Auto Switch – Go to Settings → Connections → Wi-Fi → Advanced → Switch to Mobile Data and turn it off if it's causing sudden disconnections.
7. Update One UI – Network-related bugs are frequently patched. Go to Settings → Software Update.

For 5GHz Wi-Fi Issues

Some Galaxy phones struggle with 5GHz bands. Try switching your router to 2.4GHz temporarily to see if that's the issue.

Check for Interference

Microwaves, baby monitors, and neighboring routers on the same channel can cause drops. Change your router's Wi-Fi channel in its admin settings.
