I use wireless network for my internet connection. I don't use regular (wired) network interface card (NIC) installed in my computer. My friend needs regular NIC. Does regular NIC have any kind of working relationship with wireless NIC? Will taking out regular NIC affect the working of wireless one in any way? I have noticed that lights of regular NIC keep blinking even when I'm surfing the net using the wireless one. Please advice me. Thanks.
