About Networking & Wi-Fi

Wi-Fi problems are mostly physics problems: distance, walls, interference, and too many devices on one radio. This section helps you figure out what internet speed your household actually needs, where to place a router or add mesh nodes, and whether upgrading your modem or ISP plan will actually fix anything. Use the calculators to match your plan to your usage instead of paying for gigabit you never use.

Frequently asked questions

How many Mbps do I really need?

Per person, plan for about 25 Mbps of active use (video calls, streaming, gaming). A family of four averages 100 to 300 Mbps total. Anything above 500 Mbps is usually wasted unless you have heavy 4K streaming or large file transfers. Our internet speed calculator sizes for your actual household.

Will mesh Wi-Fi fix my dead zones?

Often yes, if the problem is distance. If the problem is a specific obstruction (brick wall, metal ductwork, large appliance), mesh may only partially help. The fix-slow-wifi-at-home guide walks through diagnosis before you buy hardware.

Where should I put my router?

Central to the house, elevated (shelf, not floor), away from appliances and metal. Closets and basements are the most common bad placements. If the ISP dictates where the modem goes, put the router elsewhere with an Ethernet cable back to the modem.

Do I need to upgrade to Wi-Fi 6 or 7?

Only if you have many simultaneous devices (15 or more) or gigabit-plus internet. For most households with standard broadband, Wi-Fi 5 (802.11ac) routers handle everything fine. New standards are more about capacity than raw speed.

Why does my Wi-Fi speed test much lower than my plan?

Usually the router, not the ISP. Old routers, poor placement, 2.4 GHz band congestion, or too many devices on one radio all slow real-world speeds. Test with an Ethernet cable direct to the modem first. If that's near plan speed, the problem is your Wi-Fi.
