SOLVED - Activating Pi Hole Stops Internet Access

Please follow the below template, it will help us to help you!

Expected Behaviour:

Pi hole should be acting as DNS server

Actual Behaviour:

Pinging Google from client laptop results in "Ping request could not find....". Connecting to web admin on Pi Hole works just fine though. I have tried the Pi Hole IP as my router DNS server and have now just limited it to changing the DNS setting on the laptop as my Internet access kept stopping throughout the house.
To set Pi Hole up, I used the following instructions : Block ads on your network with Raspberry Pi and pi-hole | Opensource.com

How are you setting Pi-hole as your DNS server?

How do I configure my devices to use Pi-hole as their DNS server?

Three methods Generally, there are three different methods that will enable devices on your network to be protected by Pi-hole. 1. Define Pi-hole's IP address as the only DNS entry in the router Rationale Only is italicized here for a reason: Pi-hole needs to be the only DNS server because it intercepts queries and decides whether or not they should be blocked. If you have other DNS servers configured, you may be sent to the correct domain, bypassing Pi-hole completely. Because of this, we…

Hi
Thank you for a very swift reply !
I have made note of the IP address of the Pi Hole Pi (Ethernet connected) and have put it into the "Primary DNS" section of my router TP LINK Admin Tool on the DHCP page
This seems to be how they suggested doing it in the article I linked.
When my house Internet kept stopping as a result then I have been setting it on the client laptop in the Ethernet connection properties.
I'll take a look at the link you sent as I am only just starting out on this and need to learn as much as possible
Thanks again
Ben

As far as I can see, the only DNS set in my router settings is the Pi Hole.
In the laptop network adaptor properties, I have definitely only set up one DNS and that is the Pi Hole
Totally bemused by this

[✗] No IPv4 address(es) found on the wlan0 interface.

You won't be able to respond to queries or get out to the Internet without an IP address.

Sorry for the wasted time and many thanks for the response
Cheers,

Hang on - I am using ethernet on this pi for its Internet access - the wlan0 adaptor should just be for things attaching to it wirelessly
So - the question still remains - how is this not working ?

Solved by installing PiHole via DietPi rather than the standard install
