Yes, the TEW-672GR is fully compatible with WDS; you can add additional Access Point(s) to extend your coverage of your wireless network. This feature works with the TEW-637AP. (Note: WDS only supports wireless g speed. The use of multiple Access Points will reduces the overall network throughput to ½ the TEW-672GR. For wireless security, WDS will only support WEP; however, you have the ability to use WPA as a non-standard configuration for securing WDS feature).
