Problem

My X4’s LINK light continually blinks and does not stay solidly lit.

Solution

There are several issues that could cause this problem. Check these items:

•Ensure that the phone cord is firmly plugged into the wall jack and the ADSL jack on the back of the X4 (not the PHONE jack on the back of the modem).

•Verify that the jack the phone cord is connected to is enabled for ADSL service. Unless your service provider has enabled it, you cannot use a standard telephone jack for ADSL service.

•Your phone cord may be defective. Replace the phone cord with a known good one.

•You have installed phone filters on all the phones and fax machines using the same ADSL line as the X4. These devices can produce noise and interfere with your ADSL connection.
