My questions :

  1. Now, at this moment, I am not able to access Pihole web interface.
  2. How my family members can enjoy network based adblocking on their android devices by using above setup.

This is my first post, so please bear with me, if I am missing to provide required info.

What happens when you try? Use the address

http://192.168.1.10/admin

Once you are sure your Pi-hole is working, you will adjust your router's DHCP settings so that it gives out your Pi-hole's IP to use as the DNS for the local network.

Please can you create a debug log and post just the token URL here, and someone can take a look at your setup and make sure it's all okay. Either run the command

pihole -d

or use Tools > Generate debug log and select the option to upload.

Welcome!

Thank you Chris, now I am able to open the web interface. I was giving wrong IP of the Pihole's server machine, it is 192.168.1.10 while I was 192.168.1.14.

Now please tell me what router's DHCP settings are required so that we all can enjoy adfree network on android devices and this my home pc (through which I am typing this message)

Your Pi-hole is on the address 192.168.1.10 and this address is assigned to the wifi interface on the Pi-hole. This is the interface that starts wlx...

However your Pi-hole has been configured to use the wired ethernet interface. This is the interface that starts with enp... The wired interface does not have an IP address and is not connected.

You can fix this by running the command

pihole -r

and selecting Reconfigure. This will repeat the install screens. Go through the settings carefully and select the wifi wlx... interface when prompted. You can select it with the up/down keys and press Space to select it. Continue with the rest of the settings. Once complete, your Pi-hole will be ready for use.

Then you need to go into your router and find the DHCP section. Find the DNS settings in that section and put in the IP of your Pi-hole and save the changes. This will make your router tell clients to use the Pi-hole for DNS.

Finally, if you take a client and disconnect it from, and reconnect it to, the network, it will pick up the new settings and should start using Pi-hole automatically. You willl see its queries when you refresh Pi-hole's Query Log screen in your browser.

At this point you can create another debug log if you like and post the token URL here and I'll check you're all good.
