If you have flashed the stock ROM and the Wi-Fi turns on but the signal is weak, you may need to inspect the hardware.

Explain the problem: some Redmi Note 5 Pro units experience Wi‑Fi dropouts, weak signal, or inability to connect after firmware updates or modem/baseband mismatches. The community solution is an extracted/modified Wi‑Fi fix file (often a firmware blob or patch to the wireless driver/config) known as an “extra quality” fix that claims improved stability and throughput.

The solution? Flashing a Redmi Note 5 Pro WiFi fix file of extra quality.
