Hi @Basis2002,

Welcome to HP Support Community.  

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

I'm sorry to hear that you're experiencing issues with your HP Pavilion laptop after upgrading the Wi-Fi card. Error 702 typically indicates a BIOS or firmware problem, and in some cases, it might be related to hardware compatibility issues.

Here are some steps you can take to address this problem.

• Check Compatibility: Ensure that the Intel 7260 Wi-Fi card is compatible with your HP Pavilion laptop. You should check the laptop's user manual or HP's official website for a list of compatible Wi-Fi cards. If the card is not on the list, it might not work properly or require a custom BIOS update.
• Revert to the Original Wi-Fi Card: If the new Wi-Fi card is causing the issue, you can try reverting to the original Wi-Fi card that came with your laptop to see if the problem goes away.
• BIOS Update: Ensure that your laptop's BIOS is up-to-date. Sometimes, BIOS updates include fixes for hardware compatibility issues. Go to HP's official website, locate your laptop model, and check if there's a BIOS update available. If there is, follow the instructions provided to update your BIOS.
• Drivers and Software: Make sure you have the latest drivers and software for the Intel 7260 Wi-Fi card installed on your laptop. Visit Intel's official website to download the most recent drivers for the card.
• Hardware Inspection: Check that the Wi-Fi card is properly seated in its slot. Sometimes, a loose connection can cause issues. Turn off the laptop, remove the card, and then reinsert it carefully.
• Backup and Recovery: Before making any changes to the BIOS or your laptop's hardware, be sure to back up important data. If something goes wrong, you'll have a backup to restore from.

Remember that updating the BIOS carries some risk, and if not done correctly, it can potentially brick your laptop.

I hope this helps. 
 

Take care and have a good day.
