What are the key settings to configure when using two routers in a house?

I have a fibre connection, and two routers because of the layout of the building. Basically I go from Fibre > ONT > Ethernet > Router #1 > Ethernet > Router #2.

Both routers are WiFi access points.

My problem is that WiFi device connectivity on Router#2 is erratic and keeps bombing out. So I’m wondering if I understand the configuration requirements correctly.

These are the key points as I understand:

  1. Both routers should have static IP Addresses.
  2. Only one router should be the DHCP server (IPv4 and IPv6)
  3. Should I worry about bridging?
  4. WiFi SSID should be different on both routers? Or same?
  5. What about the Internet settings? INTERNET_TR069_ADSL_0_100 / INTERNET_TR069_VDSL_VID_10 / INTERNET_TR069_ETH_VID_10 / INTERNET_UMTS? Should they be deleted on router #2 or not?
  6. Is there something to do with NATS that I need to do? on Router #2?

Thanks
