I can connect to my Archer C20, but there's no internet connection.
Hi! I recently bought the Archer C20, and I've had some trouble trying to connect to the internet with it. I figured out that I have to input my static IP manually and I thought that would fix it. Seemingly it did, because all of the LED indicators are green, however, when I connect to the wifi, I have no internet connection. I've tried multiple times to reboot, reset, plug out and plug in the power and coaxial cable, I tried to clone my computer's MAC address. Even connecting my PC to the router with a cable doesn't work. I contacted my ISP and they said that everything I'm allowed to change my MAC address freely, but that there's no new device being registered. When I use my old router, the wifi works just fine. And now I have no idea what to do. I think I might just have to return the router and get a new one.
