1. Place the router in a central location.

We know the wires you plug into the router are probably set up in the corner of the room, but it's better to run them over to a more central spot.
Ideally, it'll be within sight of wherever you sit and use the Internet most.

Here's what your WiFi setup is probably like right now:

2. Avoid surrounding it with metal objects.

So the kitchen is not the best place for your router to live.

3. Concrete or brick walls are the enemy, too.

Enclosing the router with concrete or brick on a couple sides won't help your signal reach the furthest corners of your home.

Additionally, floors and ceilings tend to be more transmissive than walls, Cole noted.

4. Don't keep the router near a microwave.

If you've noticed the Internet slowing down whenever you're heating something up in the microwave, it's not just you. Microwaves operate around the same frequency as wireless routers, and even the tiny bit of radiation that escapes the microwave can disrupt your signal.

5. Set it up high.

WiFi routers emit radio waves, which spread out and down from their source. 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.

6. Position the antenna upward for a better horizontal reach, or sideways for vertical reach.

In a multi-story home, positioning a router's antenna sideways can help you get a better signal upstairs. Pointing an antenna up helps the router reach farther laterally.

If your router has two antennas, though, take care of all possibilities by pointing one antenna up and the other to the side. And if you've got a router without any antennas, make sure you stand it the way it's made to go. That is, don't lay a vertical router on its side.

7. Think twice about putting a router somewhere with a lot of people.

Water inhibits WiFi signals. Since humans are mostly water, a bunch of us hanging out in a room together can interfere with the signal. You may have noticed getting worse Internet connections in crowded spaces. And yes, you probably want a good WiFi signal in the room where people like to gather, but all those bodies might slow it down in other parts of the house.
