No more Wi-Fi dead zones: Tips for improving your signal at home

I've had a few reader queries about how to get better Wi-Fi signals at home.

The Wi-Fi that comes with your may not be up to the task of covering all the corners of your house. Almost every house has dead spots where the Wi-Fi signal (and ) slows to a crawl or is lost all together.

Depending on placement, walls and doors can cut way down on the signal strength as you move away from your Wi-Fi router.

Your router should be centrally located in your home, but this is usually not the case. If your router is in a cabinet or closet or at the far end of the house, try moving it higher (don't leave it on the floor) and out in the open—every door and wall between the router and your devices slows things down.

If you're using the Wi-Fi router that's built into your broadband modem, you'll almost always be better off using a separate Wi-Fi router (perhaps with an extender) or even a mesh Wi-Fi system that uses multiple access points placed in different areas of your home.

But first, let's talk about internet speeds. Don't confuse slow Wi-Fi with a slow internet plan.

You pay for your based on how fast the data connection is to your house. I recently upgraded my home internet from a plan with a speed of 24 megabits per second to a plan with 1,000 Mbps, and it's totally worth the extra cost.

You'll never be able to get speeds faster than the service level you are paying for.

If you have multiple people in your house streaming video or gaming, it can really be taxing on a slow internet plan.

But if your internet service is fast enough for your needs, a likely reason for slowdowns is weak Wi-Fi coverage. You probably know the places in your house (or in your yard) where the signal drops off.

Can a cheap (or not so cheap) Wi-Fi extender help? Perhaps.

A Wi-Fi extender is a small box that plugs into the wall and wirelessly extends the to a specific area of your house.

You'll get better results if you use an extender that's the same brand as your existing router.

Cheaper (under $40) extenders can extend your Wi-Fi to the far corners of your house, but they can't transmit and receive at the same time. They just relay the signals back to your router, which will slow things down.

So, extenders work, but in a pretty limited area and at the price of reduced speed.

But reduced is better than no coverage.

The better extenders ($50 and up) have multi-band radios and can use different radio frequencies to transmit and receive at the same time, which is better but still not ideal. Some of these extenders cost $100 or more.

If you'd like to try an extender, my advice is to do some research on a site like thewirecutter.com to find a good one and buy from a place that has a good return policy so you can send it back if you don't see an improvement.

If your house is large, you should consider a mesh Wi-Fi system like the ones offered by Eero, Google, Netgear, D-Link or Linksys. There are other brands as well.

These use a base router and one or two (or more) satellite routers that are placed throughout your home. You might place one on a different floor. The mesh routers all talk to each other, and some use different radio frequencies to route traffic to keep speeds high throughout your house.

I'm currently using the Eero Pro system with one router and two satellites, and I'm very happy with the coverage.
