En mi opinión, si tienes una conexión estable, es decir, si puedes navegar/descargar/transferir con normalidad entonces no debes darle importancia al aspa roja de dicho icono, ya que dicho problema no estaría afectando gravemente (ni levemente) al estado de tu conexión...
· ¿Has utilizado el solucionador de problemas de red de Windows?, eso lo primero.
Click derecho en el icono > "Solucionar problemas".
· ¿Te indica algo el resultado del solucionador de problemas?.
Sigue estas indicaciones para intentar solucionar el problema:
1. Inicia la aplicación Regedit (
C:\Windows\Regedit.exe)
2. Localiza y exporta (click derecho > exportar) la siguiente clave de registro para guardar una copia de seguridad:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network3. En dicha clave, elimina el valor de tipo binario (REG_BIN) que tiene el nombre
Config.
El valor se reconstruirá cuando reinicies sesión de usuario en Windows.
4. Desconecta el router, reinicia el PC, y reconecta el router, hazlo en ese orden.
Con suerte será suficiente para solucionar el problema causante del aspa roja en el icono.
