Good the chipset install helped but I’m a bit confused.
1. According to what I’m reading, your notebook came configured with internal wireless. If that’s true, why are you using an additional external wireless adapter?
2. Unless you know the internal wireless is dead, has been removed, or didn’t come with that configuration, remove the external wireless card from the notebook and uninstall any and all wireless drivers you’ve installed.
3. Next, install the Quick Launch Buttons. This is required to turn the wireless on and off via the button next to the power button (except through device manager).
4. I don’t know which onboard type wireless card came in your unit (if equipped) but either way, reboot and install the Broadcom driver from HP. If that doesn’t fix the onboard wireless, uninstall the Broadcom driver, reboot, and install the Atheros driver. Confirm operation through device manager.
5. If you have no internal wireless card. Uninstall all previously installed wireless drivers, shut down, reinstall the external wireless card, start the computer, and install the Broadcom driver only (It is not Atheros). If none of that works, you may need a different Broadcom driver for the Compaq external wireless card.
thanks
