## Introduction

I have been struggling to get ArchARM setup on my Raspberry Pi.
I believe I have identified the root cause of my current issue; however, I could be wrong or still have more issues to troubleshoot and resolve.
Without the Raspberry Pi, I am unable to configure my router to use PiHole or AdGuard Home as a network-wide ad-blocker.

Fortunately, AdGuard Home has a few servers that I can use to see whether or not it blocks ads until I can get my Raspberry Pi setup.
Unfortunately, there will not be any back-end dashboard to view to administer block lists or see blocked traffic.
Since ads are so prevalent these days I am not worried about wondering if it is blocking ads.

## Baseline

To gauge the effectiveness, a few sites have to be checked before the settings are applied.

## Setup

The next step is to configure the router’s DNS to use AdGuard Home’s DNS servers.
AdGuard Home’s Knowledge Base provides the steps to accomplish this:

1. Open the preferences for your router
Usually you can access it from your browser via a URL (like http://192.168.0.1/ or http://192.168.1.1/).
If you don’t remember it, you can often reset the password by pressing a button on the router itself.
Some routers have a specific application which should be already installed on your computer in that case.

2. Find the DNS settings
Look for the ’DNS’ letters next to a field which allows two or three sets of numbers, each broken into four groups of one to three numbers.

3. Enter our DNS server addresses there
176.103.130.130
176.103.130.131

I have a LinkSys WRT32 router and found this under Advanced SettingsInternet Connection Settings.

All I had to do was change this to Custom and provide the DNS server addresses.

## Verification

All that is left to see is how it performs using the same sites as before - using a hard refresh to prevent cached ads from being served.

## Conclusion

It seems as though some ads are being blocked but I am surprised at how many are still being served.
To me this looks like the ad-blocking lists need to be updated but cannot say for certain without installing it myself.

I still will be loading Pi-Hole or AdGuard Home on my Raspberry Pi as this keeps my data in-house.
As much as I love of what I have seen of AdGuard Home’s admin dashboard, this experience is not re-assuring me of it’s effectiveness.
In the end, the more effective product will be the one I use.
