How to transfer the function of the DHCP server to the router?

Question

Computer networks

There is a Gpon-modem Nokia (Alcatel Lucent), distributes ip to wired and wireless clients, not fast enough. And there is a Tp-Link Archer C7 router. I connect them with a lan. I hang up wired clients on Tp-Link. I disable it on Nokia and enable the DHCP server on Tp-Link. The devices are all online, but there is no internet. Can you please tell me what to check?

Answer 1

1. Plug the cable from Nokia into the blue port of the router, not into the yellow one;
2. It was not necessary to disable DHCP on Nokia, return it;
3. You need to make sure that the network from Nokia and the LAN network on Tp-Link are different (for example, one is 192.168.0.0/24, the other is 192.168.1.0/24), if not, then change one of the networks (usually the DHCP settings change automatically, but it is better to check this too).

Answer 2

Set the default gateway for Tp-Linka, it should be a Nokia router (thumbs up, but it might work).

Answer 3

In the DHCP settings on TPlink, the default gateway should be the Nokia ip address (like the same network) on nokia dhcp should be turned off (also do not forget about DNS or ip white DNS (Google, ISP, etc.) or ip nokia
