How to improve home Wi-Fi without buying the wrong equipment
Move the router and separate the bands before you buy a mesh kit. Buy more hardware only when a walk test still fails.
Spend after the walk test
Improve placement, update firmware, and put stationary computers on Ethernet if a cable is possible. Then retest the weak room. If it is still weak, add a node with a wire. Read dead zones and mesh versus an extender before you check out.
Who this is for
Households with a working internet plan and a Wi-Fi problem in part of the home.
Order of operations
- Test beside the router and in the bad room.
- Raise and center the router using placement rules.
- Give the work laptop 5 GHz or Ethernet. Leave 2.4 GHz for devices that need range.
- Use the planner only to estimate how many nodes to price, not as a floor plan.
Limits
Apartment buildings can be so crowded that new hardware barely helps. In that case a wired backhaul to the room you use, or asking the building about infrastructure, beats another radiator of Wi-Fi.
Questions readers ask
Should I buy the fastest router on the shelf?
Only if your devices and your internet plan can use it, and the problem is not a wall. A fast router in a closet still fails the back bedroom.
