When I look under Device Manager>>Network Adapters, I see both "Broadcom 802.11n Network Adapter" and "Realtek PCIe GBE Family Controller" listed. What's the difference? Do I have two WiFi cards/drivers?. I think Broadcom is the one that is connected/used via WiFi to my router.If it helps here is some more detail:Broadcom 802.11n Network Adapter - Location: PCI bus 6, device 0, function 0Realtek PCIe GBE Family Controller - Location: PCI bus 1, device 0, function 0Before I did clean install from Win 7 to Win 8.1 on the laptop I think (I may be wrong) it used the Realtek for WiFi. I'm having some issues with loosing connections and have to run windows WiFi "troubleshoot problems" frequently to re-establish connection but, that's another topic for now.Thanks for your help.
