The phone reset that can revive Wi-Fi without erasing your data

Resetting network settings can clear stubborn Wi-Fi, Bluetooth, mobile data and VPN problems on phones and tablets, but it will delete saved connections and passwords.

A weak or broken Wi-Fi connection on a smartphone does not always point to a faulty router or poor reception. In many cases, the fault sits on the device itself, and CHIP says a network reset can be an effective first fix on Android, iPhone and iPad. The appeal is that it targets only connectivity settings, rather than wiping the phone or tablet completely.

The reset is worth trying when a device can no longer join Wi-Fi networks, Bluetooth connections fail, calls drop, or VPN access stops working. Apple says similar steps can also help when an iPhone or iPad still cannot connect after checking the router, confirming that the device is within range, and restarting the modem or router. Motorola gives comparable advice for Android phones, where persistent Wi-Fi, Bluetooth, mobile data or hotspot faults may be cleared by resetting network settings.

The important trade-off is that the procedure removes saved network information. That includes Wi-Fi names and passwords, paired Bluetooth accessories such as headphones, speakers and car systems, cellular network configuration, and saved VPN profiles. Apple also notes that APN settings can be removed. Because of that, users should make sure they know the relevant login details before they proceed.

On Android, the path to the reset depends on the manufacturer. CHIP says Google Pixel users can usually find the option under System, then Reset options, and then “Reset Wi-Fi, mobile & Bluetooth”. Samsung places it elsewhere, under General management and then Reset. Once the reset is complete, the phone rebuilds those connections from scratch, which is often enough to clear corrupted settings and restore normal connectivity.
