Causas identificadas

3 causas
#1

Fallo de hardware del adaptador de red

75%

El adaptador de red físico en sí mismo puede haber fallado debido a la antigüedad, una sobretensión eléctrica o un defecto de fabricación. Esto explicaría por qué no aparece en el Administrador de dispositivos en absoluto.

#2

Archivos de sistema corruptos o problema del sistema operativo

60%

Archivos críticos del sistema operativo relacionados con la detección de hardware o la gestión de controladores podrían estar corruptos, impidiendo que el adaptador de red sea reconocido. Esto podría deberse a una actualización defectuosa de Windows o a malware.

#3

Problema de placa base o chipset

40%

Si el adaptador de red está integrado en la placa base, un problema con la propia placa base o su chipset podría ser la causa principal. Este es un problema de hardware más grave.

Soluciones recomendadas

6 soluciones
💡

Perform a System Restore

95%Official
If the issue started recently, try reverting your system to a previous restore point where the network adapter was working.

🤖 AI Analysis

"The user explicitly stated the issue started 'Recently, after a software update.' A System Restore is designed to revert the system to a previous state, which is highly likely to resolve an issue caused by a recent software update."

💡

Check BIOS/UEFI Settings

85%Official
Ensure the network adapter is enabled in the system's BIOS/UEFI settings. Sometimes it can be accidentally disabled here.

🤖 AI Analysis

"The network adapter is not showing up in Device Manager, which could indicate it's disabled at a lower level. Checking the BIOS/UEFI settings is a crucial step to ensure the integrated hardware is enabled before troubleshooting software or driver issues."

💡

Run System File Checker (SFC)

75%Official
Use the `sfc /scannow` command in Command Prompt to scan for and repair corrupted system files.

🤖 AI Analysis

"A recent software update could potentially corrupt system files, leading to hardware not being recognized. Running SFC is a good step to check for and repair such corruptions."

💡

Update Chipset Drivers

70%Official
Download and install the latest chipset drivers from the motherboard manufacturer's website.

🤖 AI Analysis

"Since the network adapter is integrated, chipset drivers are essential for its proper functioning. A software update could have installed incorrect or corrupted chipset drivers, or the update might have been related to chipset functionality. Updating them is a logical step."

💡

Test with a Different Adapter

50%Official
If it's an expansion card, try reseating it or testing it in another slot. If it's integrated, consider using a USB network adapter to confirm connectivity.

🤖 AI Analysis

"While the user confirmed it's an integrated component, the solution suggests using a USB network adapter to confirm connectivity. This is a good diagnostic step to isolate whether the problem is with the integrated adapter or the system's ability to connect to a network in general. However, it doesn't directly fix the non-appearing integrated adapter."

💡

Check Motherboard for Physical Damage

20%Official
Inspect the motherboard for any visible signs of damage, such as burnt components or swollen capacitors.

🤖 AI Analysis

"The user's problem description focuses on the adapter not showing up in Device Manager and a recent software update. Physical damage to the motherboard is a less likely cause given this information, although it's a possibility if other solutions fail."
