hi everyone, i'd like to have help about the devices in the post title, I'm not a geek about nets, so I need help configuring the dsl-320t modem connected to the dir-600 router.
Already tried some configuration, with dhcp enabled and disabled, tried to assign a static ip to the router and tried to put the modem in bridge mode, but fail miserably

.
Now I've resetted both devices, if I connect with the ethernet cable my pc and one of the four lan connectors on the router, and then use another ethernet cable to connect the modem port with one of the other three free router port, I can connect to internet. Any other configuration i tried has not worked.
Could you please guide me step-by-step, to try solving this problem ? now the two devices are both resetted so no custom setting is applied.
