I have a "yellow exclamation" next to the bcm 20702a0 as well as the PCI device driver. I have tried HP Support Assistant and Windows troubleshooting to solve but has not worked. I really don't know what each of these drivers work with on my computer.
Hard drive was replaced on 11/21/13 and Windows 7 Home Premium 64 bit reinstalled. I had to reinstall Microsoft Money Deluxe and Trend Micro Maximum Security programs. After that I installed Quicken 2013Deluxe. Recently installed HP Support Assistant and Windows Live Essentials.
I am including a screenshot of the hardware ids on the bcm and the PCi driver. Look forward to finding a solution.
