So I have a TP-Link Archer D7 router running on 10meg ADSL. They have recently upgraded my area to 40meg VDSL. The Archer D7 does not support VDSL for some stupid reason. I am waiting for Telkom to upgrade my line to the 40meg VDSL. In anticipation I have a bought a D-Link G225 router which supports VDSL. What I want to know is how do I setup the D-Link to be a modem only and route all traffic via the TP-Link router? TIA
