Tags: #IPv4
Model: Archer C20  
Hardware Version: V5
Firmware Version: 0.9.1 4.17 v0001.0 Build 200915 Rel.56357n(5553)

I know my router's LAN IP Address. But I want to know my Modem's LAN IP Address to which my router is connected, so that I can access Modem settings in future. Is there anyway to know that? 

A sticker on the backside of the modem says it's IP Address is 192.168.1.1, but it won't work. Please help me out. I am ready to use third party utilities and services to know my Modem's LAN IP Address as well.

Unless your ONT Modem is in bridge mode, Archer C20's WAN default gateway should be the ONT Modem LAN IP address:

Thank you for the reply. But I can't access the modem. I guess there is something wrong with my modem or my ISP configured it in such a way that it can never be accessed or only be accessed by them.

I see that your ISP is using PPPoE connection. In this case you should contact them and ask if accessing their ONT modem is allowed/possible.

You also have a double NAT introduced by this configuration - they can advise you if avoiding it is possible.

Thank you for the reply, I unplugged WAN cable from router and directly connected to my PC and still failed to access my modem. "Default Gateway" shows an IPv6 address which never works. I guess, without the need of contacting my ISP, I can say that modem is blocked from access.

Hi,

 

Likely the ONT does not have an active DHCP server, which means your PC won't be assigned a proper IP address automatially.

 

You mentioned a sticker on the ONT indicates its IP address should be 192.168.1.1. 

 

Therefore, manually configure the network adapter of your PC with a valid unused IP address like 192.168.1.8 and subnet 255.255.255.0. Then connect the PC via network cable to the ONT once more and try to access it via http://192.168.1.1 or https://192.168.1.1
