“My Wi-Fi doesn’t work.”

I hear this quite a bit. Wireless networks can be finicky and there are quite a few things to look at to ensure your network is working properly and to its fullest potential. Without getting into the deepest of technical details, the following are basic things to look at and correct when trying to improve your home wireless signal and coverage.

The first thing to do in troubleshooting is to connect a computer directly to your router via ethernet cable. This rules out that any connectivity issues you have are due to your internet service provider (ISP) such as US Internet, Comcast or CenturyLink. If you have a strong signal while connected via ethernet, then it is time to look at your router to see if you can fix the problem with the wireless signal that is being spread through your home.

Next, power cycle your router. Unplug the power cord, wait 10 seconds and then plug it back in, giving it time to get back up and running. This generally solves temporary problems, but will not fix any bigger problems or long-term issues.

If that doesn’t work, review the router’s placement. Routers can be placed under desks or behind other electronics like a TV, and if you have problems, shifting that placement can help. It may be that, for your setup, the router needs to be in plain view in order to maintain adequate coverage.

The construction of your home can be a factor here, and what may work in one home or even one room may not work in another room with a similar layout. The material of your walls matters; brick walls are typically not good for Wi-Fi signals. As I understand it, wireless signals are stronger going up than down.

If you have ever tried to get into the administrative settings on your router (logging into your router), you can see that there are a lot of settings that you may have never heard of before. One of these settings is “channel.” The channel is not something you normally need to change, but there are ways to see if the same channel is being used by your neighbors and causing interference. If that is the case, you can look for a stronger channel and manually change it.

Another way to improve Wi-Fi in your home is to use a powerline adapter, wireless extender or both.

Powerline adapters are quite amazing. They connect between two units, the first one directly connected to your router and the second one connected to a device of your choice (i.e smart TV, streaming box, computer, etc.) via ethernet cable. Both powerline adapter units plug into your wall outlets and use your home’s circuitry to send the wireless signal as though it were hardlined. It is a great way to get wireless to a smart TV or streaming box.

If you have an older house with old wiring, the powerline adapter may not work as well. Both outlets you use should be on the same circuit for optimal performance, however I have seen them still work well regardless.

Wireless extenders are another way of getting your signal to spread farther in your home. They just plug into an outlet and then take your existing signal and boost it. They create a new network name — “mynetwork_EXT,” for example, with the “EXT” for extender. You can keep them the same name as your existing network, but then your devices may be connecting to the weaker part of a network rather than the extender.

Be on the lookout for the new, up-and-coming option of mesh networks, like Google Wi-Fi and the Netgear Orbi system. Supposedly mesh networks offer much better wireless speeds than range extenders and blanket an area in wireless to lose dead spots.

Hopefully this will help with some basic troubleshooting that you can do to improve your home wireless network.
