Is it literally making a clicking noise ? Is it wireless ?
What are the intervals that it's on and off -- minutes, seconds ?
My error. The clicking is coming from the computer speakers. It's the same click I hear when I click my mouse to select an internet address, for example. It starts and stops intermittently, but sometimes goes on for several minutes at a time. The interval is always the same -- about one second. Nothing else seems to be affected. I have a wireless router. but not wireless modem. I can control the volume with the computer speaker control. Thanks for responding.
