While using the Internet the other day, and had the computer speakers muted, when I heard a very faint and slow-paced beeping sound. I thought maybe it was a watch alarm buried under some laundry. Suddenly, the volume and tempo of the beeping increased alarmingly until the computer was basically screaming. The wireless connection was interrupted and connectivity did not automatically return. After the wireless was interrupted, the beeping volume and pace again decreased and eventually stopped. I turned the wireless adapter on and off a few times, and was able to reconnect after a few minutes. This has happened three or four times.
Yesterday, the wireless bars did not appear in the system tray, but the computer with network cable icon with red X. Strangely, I was able to connect to the Internet, but the icon did not change to the wireless bars. Once I restarted, the problem went away.
I haven't done anything to diagnose or troubleshoot this problem. I checked the vendor website for software updates, but everything is current.
Thanks for your time!
