I bought a modem/router with ethernet ports and wireless.

I connected it to my Quadra 650.

The display on the 650 started flickering/rolling.

Is there any reason for the two to be connected?... the 650's display and the ethernet connection.

I know the 650 is only 10/100 whilst the modem router is 100/100 but is that likley to effect the 650's display?

modem router is dlink dsl2640B
