Your Android phone connects to Wi‑Fi but keeps disconnecting or dropping the signal. This usually happens due to weak signal strength, router settings, battery optimization, or Android network glitches.
Common Causes
- Weak or unstable Wi‑Fi signal
- Router auto‑channel switching
- Battery optimization disabling Wi‑Fi
- Wi‑Fi sleep settings
- Interference from other devices
- Incorrect network configuration
- Outdated router firmware
- Android network stack glitch
Fix 1: Restart Wi‑Fi on Your Phone
- Turn Wi‑Fi off
- Wait 5 seconds
- Turn Wi‑Fi back on
This forces a fresh connection to the router.
Fix 2: Move Closer to the Router

- Avoid walls, floors, and appliances blocking the signal
Fix 3: Forget and Reconnect to the Network

Fix 6: Change Router Channel
Interference from nearby routers can cause disconnects.

Fix 7: Disable MAC Randomization
Some routers reject changing MAC addresses.

This clears corrupted Wi‑Fi, Bluetooth, and mobile data settings.

Old firmware can cause random Wi‑Fi drops.
- Log in to your router
