Hello team. 

I’m Ricardo de Jesus and I bought a 

Netely AC 7265D2W to replace a damage or not functioning 112BNHMW from a HP Pavilion DV6 laptop. The AC7265D2W it’s not recognized during start up and a error is displayed on the screen “

104-unsupported wireless network device detected. system halted. remove device and restart.” but if the card is installed after the start up the wifi signal came back and work correctly. The drivers was downloaded from netely web page as recommended.

Hi @Ricardopr04,

Welcome to The HP Support Community.  

Thank you for posting your query, I will be glad to help you.

I understand the error you're encountering ("104-unsupported wireless network device detected. System halted. Remove device and restart.") occurs because HP laptops like the Pavilion dv6 often have a whitelist of supported wireless cards in their BIOS. If the installed card isn't on this whitelist, the system blocks it at startup.

Here’s how you can address this issue:

Options to Fix the Problem:

1. Reinstall the Original Card

• If possible, reinstall the original 112BNHMW card or another card known to be supported by your laptop's BIOS.

2. Use a USB WiFi Adapter

• A simpler solution is to use an external USB WiFi adapter, which bypasses the internal card and avoids BIOS limitations.

3. Modify the BIOS (Advanced)

• Some users choose to modify their laptop's BIOS to remove the whitelist. This is risky and can brick your device if done incorrectly, so proceed with caution.
• Search online for a custom BIOS for your HP Pavilion dv6. Look for forums like BIOS-Mods where experienced users may offer guidance. Ensure the BIOS matches your laptop’s exact model.
• Flash the modified BIOS, which should allow unsupported cards like the AC 7265D2W to function.

4. Check for Supported Cards

• Research to see if there are other wireless cards supported by your laptop's BIOS that meet your needs. Cards supported by the HP Pavilion dv6 should work without errors.

5. Workaround (Install Card Post-Startup)

• While this isn’t an ideal solution, as you've discovered, installing the card after startup allows it to function. To make this process smoother, you could disable the internal WiFi card in the BIOS (if possible) and use the new card in this manner.

I hope this helps. 

Take care and have a good day.
