don't put your dsl modem too close to your monitor.

I rearrange my table several days ago, and place my dsl modem next the my monitor. I discovered everytime, when I turn on my pc, the atm will disconnect. I tried to disconnect my network cable between the pc to modem, and reboot pc, atm still will disconnect. After, it reconnected, I clicked my online game and the atm will disconnect again, so I realized it must be the magnetic field around the monitor.
