Hi everyone.

My friend bought a new AX1800 router. I still have experience with the TP-Link from the TL-WR542G, which was a great piece. I will not comment on the degradation of what web management looks like, namely that TP-Link merged MAC filtering together for LAN and Wifi which I acknowledge as progress so it is the possibility of simulating web managements. However I have never met in over 15 years so that the router cannot communicate with the modem via the WAN port! There were only two states, connected / disconnected, what passed from the modem is an expensive thing. I consider this to be a manufacturing defect of the AX1800. I was unable to connect the Compal CH7465LG cable modem (it is in bridge mode). The provider's network (ISP) registration page cannot be displayed either. It is not possible to communicate with the modem at all or ping it. The modem address 192.168.100.1 does not work (it works normally if the modem is connected to an external router). But of course, when I disconnect the AX1800 and return the PC to the modem, everything worked. The ISP provider limits the connection based on MAC addresses (so it fixedly assigns each participant its own IP address), even if I connected a new PC or a new routine, the registration page (http://reg.upc.sk - only works on the ISP's network) will always run to change the machine. This site from the ISP must works for everyone, whether I connect a register modem/router or not. If I choose a cloned MAC address and it is not in the ISP's registry then I should register this new "machine" through that provider's website and I currently have the Internet. Whether the MAC address is in the registry or not the modem setup must works!

There must be some communication because the AX1800 will display the correct ISP's DNS servers from the modem. However it shows an incorrect WAN IP address.

Thank you for your tips.
