What factors could be contributing to the weak and unstable Wi-Fi connection on the OnePlus 8T?

There can be several factors that contribute to a weak and unstable Wi-Fi connection on the OnePlus 8T:

1. Distance from the Wi-Fi router: If the device is far away from the router, the Wi-Fi signal strength may weaken, causing a poor connection.

2. Interference: Other electronic devices or appliances such as microwaves, cordless phones, or Bluetooth devices can interfere with the Wi-Fi signal, leading to instability.

3. Router settings: Incorrect or outdated router settings can hamper the Wi-Fi performance. This includes the Wi-Fi channel, bandwidth settings, or firmware updates.

4. Network congestion: If multiple devices are connected to the same Wi-Fi network and using high-bandwidth activities simultaneously, it can result in a weak and unstable connection.

5. Obstacles: Walls, furniture, or other physical barriers can obstruct the Wi-Fi signal, leading to signal degradation.

6. Software or firmware issues: Outdated software or firmware on the OnePlus 8T may cause compatibility issues with the Wi-Fi network, resulting in poor connectivity.

7. ISP issues: Problems with the internet service provider (ISP) or their network can impact Wi-Fi performance, leading to a weak and unstable connection.

8. Hardware problems: In rare cases, there might be hardware faults with the OnePlus 8T's Wi-Fi module or antenna, causing connectivity issues.

It is recommended to troubleshoot these factors one by one to identify the specific cause of the weak and unstable Wi-Fi connection on the OnePlus 8T.
