I need some help,
after reading this Router vs Switch vs Gateway and why NAT influences this decision
I decided to setup my Archer C7 as a router device as by this OpenWrt as router device
I connected the modem/router LAN port to routers WAN port but there was no internet access.
I tried also to connect LAN to LAN ports but still the same, no internet access.
What I understood from the pages above, to set it up I set the modem/router to bridge mode, and the router LAN interface gave it a 192.168.1.2 static address. Connected both via LAN/LAN and then LAN/WAN.
What is wrong; Thank you in advance for your time forum.
The devices are
TP-LINK TD-W8960N modem/router
TP-LINK AC1750 Archer C7 router
