I stopped forcing all my devices to use the same DNS and my network finally worked

My approach to DNS over the years has been like most people’s: pick a provider and apply it to all my devices. But despite going through the options of privacy-focused, filtering-heavy, and security-first providers, my home network still felt inconsistent. I experienced gaming consoles struggling to connect, unexpected VPN drops, and certain devices going offline without a clear trigger.

In the end, I figured out there was no problem with my Wi-Fi or router. Things were breaking only because I was forcing all my devices to use the same DNS behavior. Changing this was the only fix I needed.

One DNS rule created conflicting priorities

Every device on my network needed something completely different

One thing I had not considered was how a work laptop, smart speaker, and gaming console are different and don’t need the same thing from DNS. Because this never occurred to me, I configured them all to work under the same filtering rules.

I loved blocking trackers, so I had set up aggressive filtering across the network. This was counterproductive for devices that depended on domains that filtering blocked. As a result, specific gaming services timed out, and some smart home devices became unreliable. However, I initially scapegoated the router because all these devices were still showing strong signals.

Devices rarely announce DNS failures, which makes them difficult to diagnose. Everything will look fine, but they will not work properly. It finally clicked that different device categories had different needs.

DNS issues also did not care about benchmarks, because even when a server looks fast, you may still experience compatibility issues in real use. What mattered most was consistent DNS behavior across devices.

DNS profiles solved problems I blamed on my router

The hardest part wasn’t setting them up — it was finding the device causing the problem

DNS profiles are named configurations with three distinctions: they bundle a resolver, filtering rules, and preferences for logging. They then assign a distinct configuration to specific devices. For me, I assigned filtered DNS to family devices, an unrestricted resolver to my gaming console, and security filtering with encrypted DNS to work laptops.

Regardless of the tool you use, you can typically configure DNS profiles, even though this feature may be priced differently:

Even though it took just an hour for me to set up profiles, it took much longer to figure out the device that was ignoring them. The laptop seemed to be bypassing my DNS configuration each time I used its browser. I figured out that Chrome’s DNS setting used the OS resolver when available, which caused the browser to upgrade to encrypted DNS and bypass my router-level profile; changing the browser’s DNS setting fixed it.

I ensured DHCP reservations are set for all my devices to avoid a situation where a device reconnects and lands in the wrong DNS profile.

Matching DNS providers to what each device actually does

The right resolver depends on the job, not on which review ranked it highest

In the past, my approach was hunting down a single best DNS provider. But in practical terms, you realize that DNS providers are optimized for different purposes. The root of my problem was believing one could excel at everything.

Once I learned that DNS providers aren’t one-size-fits-all, I started treating each one like a tool for a specific task.

Gaming devices were where I saw the biggest difference after removing aggressive filtering. It eliminated the matchmaking and login issues I sometimes faced.

How little I had to think about the network

Although experts discuss a ‘fastest’ DNS, I found speeds similar in practice and negligible differences. The real change happened in my head. I was thinking far less of the network because it didn’t need constant troubleshooting or tweaking; it was predictable and reliable.

DNS profiles may not be for everyone, but if a device behaves unreliably for no clear reason or your filtering poorly fits some devices, try DNS profiles.
