Is there any known issue that could be causing weak and unstable Wi-Fi signal on Xiaomi 13T Pro?

Yes, there are several known issues that could be causing weak and unstable Wi-Fi signal on Xiaomi 13T Pro:

1. Signal Interference: Wi-Fi signals can be affected by interference from other electronic devices such as cordless phones, microwave ovens, or neighboring Wi-Fi networks. It is recommended to move away from such interference sources or change the Wi-Fi channel to minimize interference.
2. Distance from Router: If the Xiaomi 13T Pro is too far away from the Wi-Fi router, the signal strength can weaken. It is advisable to move closer to the router or use Wi-Fi range extenders to improve signal coverage.
3. Router Firmware: Outdated firmware on the Wi-Fi router can cause compatibility issues with the Xiaomi 13T Pro. Updating the router's firmware to the latest version can often resolve such problems.
4. Network Congestion: If there are multiple devices connected to the Wi-Fi network, it can lead to network congestion and affect signal strength. Disconnecting unused devices or limiting the number of connections can help alleviate this issue.
5. Wi-Fi Settings: Incorrect Wi-Fi settings on the Xiaomi 13T Pro may affect the signal strength. Checking and adjusting settings such as Wi-Fi band (2.4GHz or 5GHz), security mode, or signal strength settings can be helpful.
6. Hardware or Software Issues: In some cases, hardware or software malfunctions on the Xiaomi 13T Pro itself can cause Wi-Fi signal weaknesses. Performing a factory reset, updating the device's software, or contacting Xiaomi support for further assistance may be necessary.
