Hello, i'm trying to expand my wifi by connecting my TD-W8961N via wds to my main modem-router which is a Speedport Entry 2i. I entered the TD-W8961N interface and i enabled the wds, then i entered the MAC address of my main modem-router and i disabled the DHCP as the manual advised to do. But the TD-W8961N hasn't access to the internet yet. I have watched many videos on you tube and i have read many manuals in order to understand what is going wrong, but without any result. Could anyone please help me? Thank you!
