What could be causing weak and intermittent Wi-Fi connectivity on Oppo R11s Plus?

There are several potential factors that could be causing weak and intermittent Wi-Fi connectivity on the Oppo R11s Plus. Some of these possible causes include: 1. Distance from the Wi-Fi router: If the Oppo R11s Plus is located far away from the Wi-Fi router, the signal strength may weaken, resulting in poor connectivity. Try moving closer to the router to improve the signal strength. 2. Interference from other devices: Wi-Fi signals can be interfered with by other electronic devices such as cordless phones, microwaves, or Bluetooth devices. Keep the Oppo R11s Plus away from such devices to avoid signal interference and improve connectivity. 3. Network congestion: If too many devices are connected to the same Wi-Fi network, it can cause congestion and lead to weak connectivity. Disconnect unnecessary devices or consider upgrading to a higher bandwidth internet plan to alleviate network congestion. 4. Outdated router firmware: The Wi-Fi router firmware may be outdated, affecting the device's ability to maintain a stable connection. Check for any available firmware updates for your specific router model and upgrade if necessary. 5. Router placement and settings: Improper router placement or incorrect settings might hinder the optimal Wi-Fi signal. Ensure the router is placed in a central location, away from obstructions, and adjust the router settings (e.g., channel selection, signal strength) for better Wi-Fi connectivity. Remember to troubleshoot and eliminate each of these potential causes to determine the exact reason behind the weak and intermittent Wi-Fi connectivity experienced on the Oppo R11s Plus.
