Why iPhone Wi-Fi Keeps Dropping
In 2025, iOS 18.2 uses aggressive "Wi-Fi Assist" and iCloud Private Relay protocols that can conflict with local router security. When the iPhone's DHCP lease expires or the DNS handshake fails, the system automatically drops the connection to save power or switch to cellular data, creating a cycle of instability.

8 Steps to Fix iPhone Network Instability
Forget & Rejoin Network
Go to Settings > Wi-Fi, tap the (i) icon next to your network, and select Forget This Network. Re-enter the password to clear local handshake errors.
Disable Private Wi-Fi Address
Inside your Wi-Fi settings (i), toggle OFF Private Wi-Fi Address. This prevents the router from misidentifying your iPhone as a new device repeatedly.
Configure Manual DNS
Change DNS to 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare) in the Wi-Fi configuration to bypass slow ISP servers.
Reset Network Settings
Navigate to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. This flushes all saved Wi-Fi, Bluetooth, and VPN data to factory defaults.
Turn OFF Wi-Fi Assist
Go to Settings > Cellular and scroll to the bottom. Toggle OFF Wi-Fi Assist to prevent the iPhone from jumping to data when signal dips.
Disable iCloud Private Relay
Go to Settings > [Your Name] > iCloud > Private Relay. Turn it OFF, as it often causes DNS resolution failures and speed drops.
Reset Location & Privacy
Network stability is linked to Location Services. Resetting these under Settings > General > Reset can fix background Wi-Fi scanning bugs.
Update Router Firmware
Access your router settings via browser and ensure it supports WPA3 or WPA2 (AES) for maximum compatibility with iOS 18.2.
If your iPhone keeps disconnecting, a **Network Settings Reset** is the most effective fix. By combining this with manual DNS, you ensure a stable 2025 connection.
