How to Extend WiFi Range in Your Home

They call it disconnect anxiety,  that feeling of anxiousness when we get disconnected from the internet and all the wonderful things it contains. Sometimes the internet is down for everyone and sometimes you’re WiFi hotspot is just too far away. You can do much about the first issue, but you can extend WiFi range at your home and keep the cat videos flowing.

In this article, I’m going to go over some of the common reasons your WiFi is out of range at the worst possible times. Some of the improvements to WiFi range are cheap or free. Others will cost you some money, but it’s all for a good cause right?

Riding the Wave

WiFi is just plain old radio, so it’s subject to the same laws of physics that govern signal range for all radios. Because WiFi is an example of digital radio, scientists and engineers have figured out clever ways to overcome some of the interference analog radio experiences. Still, WiFi can be blocked by a number of things.

Some wall materials or metal pipes inside your walls can make a WiFi signal lose its potency.

The other reason range is limited comes down to plain old transmission strength and distance. Radio waves are subject to an inverse square law when it comes to how far you can be from the source and still have a usable signal.

If you are simply beyond the optimal range of the signal you only have a few choices:

• More juice
• A better antenna
• Both

That being said, let’s look at ways you can extend WiFi range compared to the range you have at the moment.

Upgrade Your Stuff

This is probably the most obvious solution, but if you are using older equipment your range may be limited by obsolete WiFi technology.

You can extend WiFi range simply by using the best WiFi technology on the market. Every new generation of WiFi improves things like speed and signal strength.

At the time of writing, the latest WiFi standard is 802.11ac. Whenever two WiFi devices try to talk to each other, they can only use the lowest common shared WiFi standard they both support.

So even if you have a new tablet with 802.11ac WiFi, your 802.11n or (gasp) older router is not going to take much if any advantage of it.

So it’s a good idea to phase out older equipment that might be bringing everyone else down.

You can also simply upgrade to a router that has a stronger signal, more antenna and is generally just better-specified. Usually router makers will specify what sort of home environment a router is good for. For example, some work better in multi-story homes.

Firmware Adventures

Using custom firmware such as those from dd-wrt can give you control over aspects of your WiFi signal that are out of reach out of the box. This is some pretty advanced stuff though, so you’ll need adult (or at least IT-person) supervision to even attempt it.

Alternatively, just look for official firmware updates for your router model. Sometimes the manufacturer can improve range and performance through bug fixes.

Location, Location, Location

Router location plays a big role in how far the signal will reach. Whenever possible, a router should be in a central spot. Not only does this evenly spread the hotspot across the home, it also helps prevent people from outside your prop
