For best network performance and coverage, the wireless set-up is what we recommend for Milo. If you are currently content with your existing router performance, you're in an excellent position to take advantage of the wireless Milo set-up, which gives you maximum coverage.
The app will walk you through this set-up, or you can find instructions here.
Setting up Milo wirelessly lets it take full advantage of your existing coverage by allowing the base to "stretch its legs" away from the router, expanding coverage well beyond its existing outer limits without amplifying signal in redundant, already-covered spots.
If you have a functioning modem/router and network, Milo works best wirelessly. But, there are some cases in which Milo might work better if it's connected directly to your router with the Ethernet cable.
It might just be that you don't want to use the Milo mobile app (to which we say, you're missing out! - on all the best features, performance, and updates Milo has to offer).
We recommend asking yourself whether you're happy with your current router. Are you getting the network speeds you paid for? Are those speeds higher than 20-30 Mbps? If so, setting up Milo wirelessly is the best choice. If not, connecting Milo to your router will get you better results.
Wiring Milo to your router also means that you will end up with two separate wifi networks - your existing one, and your Milo network. Some Milo users might prefer this.
However you decide to set up Milo, it's super easy to change your mind at any time - when you rearrange Milo, it automatically re-optimizes and adjusts to stay up-and-running at peak performance.
