What is Pixel 9 WiFi slow and disconnecting?
The Pixel 9 WiFi slow and disconnecting issue refers to a connectivity bug where the device fails to maintain a stable internet connection. Users report fluctuating download speeds or the phone randomly switching to cellular data despite being near a router.
This problem often stems from software conflicts within the Android 14/15 environment or aggressive power-saving features. It can also be caused by outdated network configurations stored in the device cache.
Step-by-Step Solutions
1. Toggle Adaptive Connectivity
Adaptive Connectivity is designed to save battery by switching between 5G and WiFi. However, it can sometimes cause the Pixel 9 to drop active WiFi connections unnecessarily.
Go to Settings > Network & internet > Adaptive connectivity and toggle the switch to Off. Restart your device to see if the stability improves.
2. Reset Network Settings
Performing a network reset clears all saved WiFi passwords, Bluetooth pairings, and VPN settings. This is often the most effective way to clear corrupt configuration files.
Navigate to Settings > System > Reset options > Reset Bluetooth & Wi-Fi. Confirm the action and wait for the device to refresh its wireless stack.

3. Change MAC Randomization
The Pixel 9 uses a “Randomized MAC” by default for privacy. Some older routers do not handle this well, leading to frequent disconnections or slow speeds.
Go to your WiFi network settings, tap the Gear icon next to your network, select Privacy, and change it to Use device MAC.
4. Update System Software
Google frequently releases “Feature Drops” and security patches that include fixes for modem firmware. Ensure your Pixel 9 is running the latest build.
Go to Settings > System > System update and tap Check for update. If a patch is available, install it and reboot the device immediately.
5. Clear Device Cache via Recovery
If the issue persists after a network reset, clearing the system-level communication cache can help. This does not delete your personal data but refreshes how the hardware interacts with the software.
Power off your phone, then hold Power + Volume Down to enter Fastboot Mode. Navigate to Recovery Mode and select the option to refresh system components if available under your specific carrier build.
