Looking to configure a mesh Wi-Fi network and have some queries along the way.
I'm exploring setting up a mesh Wi-Fi network for our home. I've looked into the topic but have some uncertainties I can't find answers to. My current setup uses a cable modem/router combo, and I'm curious whether it would work with a mesh system or if I need separate devices. I'm concerned that using a combo might impact performance. Should I purchase a new router and modem, preferably from the same brand as the mesh system? Thank you for your assistance—feel free to ask more questions later.
Consider your existing router at the new location before making any purchases. This might seem like a strong opinion, but I don’t believe automatically switching to mesh WiFi is suitable for smaller homes. A single access point in the center usually provides enough coverage unless your home has unique features like large walls or underground living spaces. Too many devices competing for bandwidth doesn’t always improve performance; they need to reduce interference so you’re not constantly trying to link to another network inside the house. Let marketing influence your choices instead of your needs.
Agreed. Considering a modest 1500 square foot single-story home, that’s a strong point. With just one Wi-Fi access point, achieving consistent 5 GHz coverage throughout the house isn’t feasible, even with WiFi 6E. This limitation remains due to regulatory power constraints. While 5 GHz can travel through a multi-story building, mesh networking becomes more viable when devices are spread across different areas and use separate channels. For a two-story home, having three mesh nodes can suffice if they operate on distinct channels, especially without strong interference outside the premises. Placement plays a crucial role—typically only 2-3 APs should be within range at any given time. Client devices largely control AP switching unless the mesh system supports advanced settings, like prioritizing certain bands or signal strengths. I’ve used four APs in this configuration, and careful placement helps keep signal strength limited to no more than two or three points in my area. The 802.11kvr protocol can aid rapid AP selection, but it doesn’t fully resolve the issue of a device being unable to switch to the optimal connection based on location.
Thanks! For sure I'll try my current router before committing to mesh! I've been in houses of similar size where there is only one AP; there were spots where there was less signal, and the speed was noticeably slower in those spots which is what I want to avoid. I'm still wondering though if I did decide to buy a mesh system, should I also buy a new modem or would using the router/modem combo that I have work? If a mesh system would work better with just a modem, then it may be worth it to just save some money and stick with what I have already instead of buying both a mesh system AND a new modem.
I support testing your current router before purchasing anything. If it performs well in your new environment and you connect it to a mesh network, the main concern is whether the mesh can operate as an AP-only setup (without router capabilities) or if the router/modem needs to be adjusted to simply forward traffic without routing. If neither option is feasible, you'll face a double NAT configuration, which is generally not a problem for most users but can lead to issues with inbound-only connections—such as accessing a home NAS from outside or certain gaming scenarios. I own one and it works fine, though I also lack inbound-only access.
