The typical "Wi-Fi disconnects at 5GHz every ~minute" problem on
Realtek chips is RTL8852BE.
An effect of the RTW89 driver, not the signal or the router.
Detected by: reason=3 locally_generated=1, good signal, no missed retries/beacons and cuts at regular intervals.
What worked (Ubuntu, kernel 7.0):
- Disable driver power-save (/etc/modprobe.d/rtw89.conf:
- disable_ps_mode, disable_aspm_*). Disable D3cold via udev.
- Update firmware rtw8852bt_fw.bin to v0.29.122.2 (the key point). Set 5GHz band and regdomain US. Automated and documented in: https://

Solución al problema típico de "Wi-Fi se desconecta en 5GHz cada ~minuto" en chips Realtek RTL8852BE
El problema típico de "Wi-Fi se desconecta en 5GHz cada ~minuto" en chips Realtek RTL8852BE es
un efecto del driver rtw89, no de la señal ni del router. Se detecta por: reason=3
locally_generated=1, buena señal, sin retries/beacons perdidos y cortes a intervalos regulares.
Lo que funcionó (Ubuntu, kernel 7.0):
1. Desactivar power-save del driver (/etc/modprobe.d/rtw89.conf: disable_ps_mode, disable_aspm_*).
2. Desactivar D3cold vía udev.
3. Actualizar el firmware rtw8852bt_fw.bin a v0.29.122.2 (el punto clave).
4. Fijar banda 5GHz y regdomain US.
