I have a desktop box with both a regular ethernet NIC and a "wireless PCI express card LAN Adapter". The NIC is plugged into a wired router (which I use to split my internet connection between this and another PC).
So as far as I'm concerned, I'm not - or at least should not - be using any sort of wireless connection, but there's a little blue LED with an antena icon that's always blinking, fairly reliably if not necessarily regularly. I believe it's a wireless signal indicator, although I guess it could also maybe mean bluetooth (but I don't have any bluetooth devices either). Should I be worried that others might be connected to my computer? Why does the light blink if I'm not intentionally using any sort of wireless connection/protocol?
It's an HP Pavilion running Vista, and the case looks like this:
You can kind of see two LED indicators just unter the HP logo in the center. The antenna icon sort of looks like this:
I show two items in my "Network Connections" dialog, a regular Local Area Connection, as expected, and a Wireless Network Connection, which I've disabled (but still, the light, it blinks). Could I be connected to a neighboring wireless network and not know it? Is there an easy, definitive way to tell? Or am I just letting that little blue blinky get to me?!?!
