| Method | Complexity | Efficiency | When to use |
|---|---|---|---|
| Physical button / Fn | Low | High | If the adapter is disabled by hardware |
| device Manager | Average | Average | In case of driver or codec errors |
| Command Prompt (CMD) | High | High | To reset network settings and clear cache |
| BIOS/UEFI settings | High | Critical | If the device is not detected by the OS |
Using the command line requires caution, but can often reset frozen network services. Commands netsh winsock reset And netsh int ip reset Reset network settings to factory defaults. This is useful when software conflicts prevent connection even with a working driver.
