What could be causing my Xiaomi Mi 5c to have poor Wi-Fi reception and frequently disconnect from the network?

There could be several factors contributing to poor Wi-Fi reception and frequent disconnections on your Xiaomi Mi 5c.

1. **Distance from the router**: Ensure that your Mi 5c is within a reasonable range from the Wi-Fi router. Thick walls or long distances can weaken the signal strength.

2. **Obstacles**: Check if there are any physical obstacles like walls, furniture, or appliances that could be obstructing the Wi-Fi signal. Reposition the router or your Mi 5c to minimize interference.

3. **Signal Interference**: Other electronic devices such as cordless phones, microwave ovens, or baby monitors operating on the same frequency can cause interference. Moving such devices away from the router may help.

4. **Outdated router firmware**: Ensure that your router has the latest firmware installed as outdated firmware can lead to connectivity issues. Visit the manufacturer's website for firmware updates and install them if available.

5. **Network congestion**: If multiple devices are connected to your Wi-Fi network simultaneously, it may lead to congestion and reduced performance. Limit the number of connected devices or consider upgrading your internet plan.

6. **Wi-Fi settings**: Check if your Mi 5c is connected to a crowded Wi-Fi channel. You can change the Wi-Fi channel in the router settings to avoid interference. Additionally, verify that your Mi 5c's Wi-Fi settings are configured correctly.

7. **Software issues**: Ensure that your Mi 5c's operating system is up to date. Software updates often include bug fixes and improvements related to Wi-Fi performance.

If none of these solutions resolve the problem, it might be worthwhile to contact Xiaomi customer support or consider seeking professional assistance for further troubleshooting.
