I have two routers in my house one of which is in the attic.
Router in attic or basement.
If possible place your router off the ground and in plain view like on a shelf or tv stand.
The google wi fi system is a simple yet powerful router that promises to boost wi fi connectivity to every room in the house including the attic and the basement.
One way is to buy a long ethernet cable keep it under 300 feet plug it into the modem and the router and move.
Your router needs to be connected to a modem.
Place the router in a higher position.
Mounting the router to a wall or setting it on a high shelf can give you a better signal especially if you live in a two story house and want a good connection on both floors.
If your router is in a suboptimal spot the basement for example try moving it.
Try to choose a central location at eye level.
The one in the attic has been going strong for 2 plus years.
A mesh router can help.
No wi fi in the attic.
If you have two levels you use the most the best placement to cover both stories is either the ceiling of the lower floor or the ground of the higher floor.
However when setting up an extender for a floor above or below the router such as for a basement or attic you ll need to take account of the extra height and all the wood steel and plaster in.
This may limit where you place it depending on where your modem is and the length of the ethernet and power cables.
Wifi routers emit radio waves which spread out and down from their source.
I put it in the attic because i needed a wifi signal on my back patio and placing the router at a particular place in the attic is what gave me the strongest signal on the patio.
Whether it s a wire shelving unit a steel desk the refrigerator in the kitchen or the water heater in your basement large metal objects will reflect.
