If the device is already installed in your computer (even if it's not working correctly), you can use Windows' built-in tools to get hardware information:
The numbers represent a specific certification or homologation number issued by the Brazilian government. This certificate confirms that the wireless module complies with local radio frequency laws and is safe to use inside electronic devices sold in Brazil. Who Actually Made the Card?
For wireless driver developers and hardware manufacturers, this act signals a move toward alignment with international standards, specifically referencing FCC (USA) and European ETSI guidelines. The regulation clarifies testing methodologies for:
This paper examines the Anatel-certified wireless device identified by the code "2504 09 3987," analyzing its regulatory context, technical characteristics implied by certification records, likely RF performance considerations, compliance testing processes, and implications for manufacturers and consumers. Where direct device documentation is unavailable, this paper infers probable attributes from Brazilian telecom certification practices and comparable devices. anatel wireless drivers 2504 09 3987
Have you run into this specific code 2504 09 3987 ? Check your device’s label or contact the importer — they’re required by law to provide driver support for ANATEL-approved products.
Go to Device Manager > Network Adapters , right-click the wireless device, and select Properties > Details > Hardware Ids . Look for the VEN code (e.g., 8086 for Intel, 14E4 for Broadcom).
In other cases, the numbers "2504" and "3987" also appear in different contexts, such as Brazilian telephone prefixes belonging to operators like Claro S.A., which are also cataloged by Anatel. However, in the specific context of "wireless drivers," the physical hardware model is the relevant link. This ambiguity is common with older or white-label hardware, where the search often requires a bit of detective work. If the device is already installed in your
Finally, consider consumer empowerment. Most people won’t memorize or decode strings like "anatel wireless drivers 2504 09 3987." But improving discoverability — searchable certification portals, embedded validation in device settings, or simple QR-links on packaging — would turn cryptic codes into meaningful assurances. This reduces fraud, discourages counterfeit devices, and strengthens trust in the networks we rely on.
When working with networking hardware, it is crucial to obtain drivers, firmware, and documentation from official sources. Unofficial driver download websites can be risky, often containing outdated, corrupted, or malicious software. The table below outlines the best official resources for your equipment.
To download the functional driver, you must find out if your chip is Broadcom, Atheros, or Realtek. You can do this easily through the Windows Device Manager using Hardware IDs. Have you run into this specific code 2504 09 3987
If the above methods fail, you can manually search for the driver package using the hardware's model number (). Look for an executable file (ending in .exe ) from a trusted source, such as a reputable tech database.
Look for a string containing VEN_168C (which denotes Qualcomm Atheros). Step 2: Download Official Manufacturer Drivers
The ANATEL 2504-09-3987 certification number is most commonly stamped on a physical mini-PCIe wireless card model known as the or AR5B95 . This combo card supplies both 802.11b/g/n Wi-Fi and Bluetooth 3.0 to several older laptop families: Tarjeta Wifi Para Lenovo Ideapad S300 Anatel 2504-09-3987
