Something in Vista causing Wifi interference?

by snowkilts / March 27, 2008 11:59 AM PDT


Does anyone know of something in Vista that could cause a wifi signal to shutoff or become garbled briefly at precisely 1 minute intervals?

I am using Linksys music bridge to stream audio wirelessly from my HP DV series laptop running Vista Home Premium to a set of speakers. The audio becomes garbled or shuts off completely for 2-3 seconds at precisely 1 minute intervals. Any suggestions as to what could be causing this, or ideas on how to track it down would be greatly appreciated.

I believe I have eliminated all other software and hardware and isolated this problem to either Vista or the HP laptop. Here is some additional information:
- The problem does NOT occur if I connect to my router with a wire instead of wirelessly.
- The problem does NOT occur under any circumstances if I try to stream audio from my old computer, which is a Toshiba laptop running XP.
- The audio disruption is not dependent on the media player; I have tried three of them.
- CPU utilization is around 20%

Here's the URL for the Linksys music bridge:

Any help would be appreciated!

Thanks for the response Bob. I was not aware of the LLTD. However, I tried disabling it a couple of times and it didn't change anything.

Some further info -- when I send continuous pings from my Vista laptop to the router, the response time jumps from 1ms to over 250ms at exactly 1 minute intervals. When I do the same from my XP laptop, the response time occaisionally jumps, but only to 12ms or so, and not in any sort of pattern or timing that I can see.

Any suggestions as to what this might be or how I could track it down would be greatly appreciated.

You would also need to test in a "lab."

I find driving out to the desert to work well. I can turn off the cell phone and on the hilltop I can see nothing for about 50 miles. Then we can run the test.

In your case you could have cordless phones, your neighbor could be using wifi, etc.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
