Hey! That’s my WiFi!

Hey! That's my Wi-Fi!

Have you ever checked your home WiFi connection and noticed a long list of possible connections? Unless you live in the woods with few neighbors you’ll very likely pick up a lot. Sometimes you get a laugh at some of the crazy names your neighbors use and sometimes a start when you see NSA_Van_9.  The thing is, your router is also popping up on your neighbors' list.  

I did just that the other day and was wondering who else might be using my WiFi. Just like stealing cable in the old days, only not as personal a connection, someone close by could be sucking off precious signal strength. What I found wasn’t as shocking as much as a surprise.

Wi-Fi use

Slow WiFi is one indicator of someone using your signal. All depending on the plan you have with your provider and your own usage.  You can quickly check what devices are using your WiFi by logging in to your router. Once logged in you will be provided with a list of the devices currently logged on. A simpler way is to use a 3^rdparty app such as Who’s on my Wi-Fi. This app will use your Wi-Fi signal and provide a list of devices currently using the signal. It is not necessary to provide any personal or router information. The list is comprised of IP and Mac addresses. Once you have the list the task becomes identifying the devices. 

I used this app to search for devices that returned a list of twenty-five devices currently logged on. After running down the list and doing some light deciphering I was able to determine good news and a surprise. The good news-No foreign devices were located. The surprise? All the devices were mine! The search revealed twenty-five devices that did not include the devices that were not currently logged on and had Wi-Fi disabled. If everything were in use the total would be over thirty.

Internet of Things (IoT)

As determined in the post Locking Down the Internet of Things we have, over time, without plan or intent, created our own IoT. That happens in most households. Excluding phones, 74% of U.S. homes have at least one smart device. Few people plan to set up a smart home system, it happens in bits and pieces. A security camera and/or alarm system, new appliance, TV, thermostat, one device at a time your IoT builds. Then a smart speaker is added that is able to control some or all of the devices and your IoT smart home comes to life. Added already to the phones, tablets, and eReaders your WiFi list expands. 

Security

With all of the security breaches that seem to be a monthly news item, we have become numb to the warnings of password and network security maintenance. It is important to perform regular checks of our home system. Especially as we add smart devices to our homes. (Are you being watched?) Properly setup new devices and be aware of what access you are granting them. 

The Wi-Fi usage check is yet another added security check but one that should be completed every so often. Just like changing your smoke alarm batteries at the seasonal time change it doesn’t hurt to set up some calendar reminder to review your home network security. This quick WiFi check not only reveals possible hacking but also helps you to get a handle on the number of devices in your home that are accessing the Internet.

Locking down the Internet of Things

WiFi security on the Internet of Things

Have you gotten all of your new tech gadgets hooked up after Christmas? Seems like every gift that had a plug also had a phone app and connected to Wi-Fi. Throughout the year as new toys or even appliances enter your home, setting up individual devices isn’t that noticeable. But after Christmas rolls through and you start setting up all the new goodies it really makes you sit back and notice-You have entered the new age of a smart home. Without realizing it we have created our own attachment to the Internet of Things (IoT).

That's a lot of things

Leichtman Research Group in 2018 found that 74% of U.S. homes had at least one smart device. Statista estimates that there will be 42.2 million smart homes in 2019. Spending on IoT devices was $23.3 billion (yes, billion) and is estimated to be $75 billion by 2025.  While there are Bluetooth connections, the primary connection for IoTs is Wi-Fi. Statista reported that the average number of connected devices per person, worldwide, in 2015 was 3.47 and is estimated to be 6.58 by 2020. That is connected devices per person. Multiply that by people in your home and the for-the-common-good devices like appliances, cameras, plugs, bulbs, etc, and that’s a lot of connectivity. 

If you want to keep up with technology it is how it’s going to be. I didn’t set out to convert the ol’ analog home to “smart”. It just happened. Garage door opener, a new appliance here and there, TVs, Hey Google, Hey Siri, Alexa, before you know it you’re your home is smart. The router sent me a message, yes it communicates as well, that the network was getting full. You’re aware of connectivity for your phones and computers but forget about the other electronics-appliances/TVs/cameras/power strips/gaming systems/eBooks, etc-that are on all the time and trying to communicate with the mother ship. Not only are these devices taxing on your home network they are all portals for security breaches.

Anyone of these connected devices can be hacked at the source, through the controlling app, or the company that provides the service. All the more reason to review your home network security.  If you haven’t done so recently, with the onset of all your new tech wonderness, you’ll need to upgrade your Internet service.  Most times these types of upgrades come with new routers. 

Security

One of the first actions you should take on all routers and new devices is set up your own logins and passwords. Many people still use the default settings, which cybercriminals are aware. Changing this information will at least slow them down. I say slow down because, as we’ve seen, anyone can be hacked. At least changing the settings will offer some protection.

For all of your connected devices actually, read the setup instructions and pay attention to what you are agreeing to during the process. Data collection is big business and those companies want your data. As consumers get more privacy savvy the product providers are finding counteractions. I recently loaded an app that wanted access to my phone’s camera, microphone, location, and to send user data. Answering no to any of those requests denied the user access. Or sometimes certain features are denied or dampened if the user doesn’t agree to the terms.

Devices that listen, your phone, TV, Echo, Google home, are also collecting data and have been proven to also be recording your conversations. In the interest of improving their service, of course. Again, go through the setup and privacy menus carefully. Understand what the device, i.e.-manufacturer is asking you to allow.

Overall, you have to understand that if you allow “smart” devices into your home you are giving up privacy. It’s hard not to get caught up in the technology craze, but understand that what you’re getting yourself into.
