Frequently Asked Questions

Why does my eero keep having DNS resolution problems?
DNS resolution problems typically occur when custom DNS providers experience outages or connectivity issues. Some third-party DNS services may not be as reliable as your ISP's default servers or major providers like Cloudflare.
What's the difference between Auto and Custom DNS on eero?
Auto DNS uses your internet service provider's default DNS servers, which are usually reliable and optimized for your location. Custom DNS allows you to specify servers like Cloudflare (1.1.1.1) or Google (8.8.8.8) for potentially faster speeds or better security features.
Will changing DNS settings affect my internet speed?
Yes, DNS settings can impact your browsing speed. Faster DNS servers can reduce the time it takes to resolve website names to IP addresses, making pages load quicker. Cloudflare and Google DNS are typically faster than most ISP DNS servers.
How do I know if my DNS problem is fixed?
Test by visiting various websites that were previously slow or inaccessible. You can also run a speed test or use online DNS checker tools to verify your DNS response times have improved.
Should I use the same DNS on all my devices?
When you change DNS settings on your eero router, it automatically applies to all devices connected to your network. You don't need to configure each device individually unless you want different DNS settings for specific devices.
