What could be causing the weak Wi-Fi signal and frequent disconnections on my Lenovo Vibe Z2 Plus?

There could be several factors contributing to weak Wi-Fi signal and frequent disconnections on your Lenovo Vibe Z2 Plus. Here are some possible causes and troubleshooting steps you can try:

1. Distance from the router: Ensure that you are within a reasonable range of your Wi-Fi router. The signal strength tends to weaken as you move farther away from the router. Try moving closer to see if the signal improves.
2. Obstacles and interference: Physical obstructions such as walls, floors, and large objects can interfere with the Wi-Fi signal. Make sure there are no such obstacles between your device and the router. Additionally, electronic devices like cordless phones, microwave ovens, and Bluetooth devices can cause interference. Keep your router away from such devices.
3. Router issues: Restart your Wi-Fi router by unplugging it from the power source, waiting for a few seconds, and then plugging it back in. This can help resolve temporary glitches in the router's software or hardware.
4. Network congestion: If you are in a densely populated area or a location with multiple Wi-Fi networks, network congestion can affect your signal strength. Try changing the Wi-Fi channel on your router's settings to reduce interference from other networks.
5. Outdated router firmware: Check if there are any firmware updates available for your router. Updating the firmware can address known issues and improve overall performance.
6. Wi-Fi adapter or driver issues: Ensure that your Lenovo Vibe Z2 Plus has the latest Wi-Fi drivers installed. Check Lenovo's support website for any available driver updates for your specific device model.
7. Signal strength settings: Some devices have power-saving features that can reduce Wi-Fi signal strength to conserve battery life. Check your device's Wi-Fi settings and make sure it is set to maximize signal strength rather than power-saving mode.
8. Reset network settings: Resetting the network settings on your device can sometimes resolve connectivity issues. Go to your device's settings, find the network or Wi-Fi settings, and look for options to reset or forget the network. Note that this will remove any saved Wi-Fi passwords, so make sure you have them handy.

If the above steps do not improve the situation, it's possible that there may be a hardware issue with your device's Wi-Fi antenna or the router itself. In such cases, it is recommended to contact Lenovo support or consult a professional for further assistance.
