How can I sort out interference on phone line?

My Belkin wireless router model number F5D7633-4 is causing interference on the line. I unplugged the router and the line returned to normal.My telephone is a Phillips CD240 cordless. Any suggestions

First ensure that EVERY telephone, Sky Box or WHY is connected via microfilter.

Next, check that your internal extension wiring has ONLY the following connections: Blue & White to 2 and White & Blue to 5.
