How to Detect if Someone’s Stealing Your WiFi – Electronics …
With WPA2 security enabled, it’s unlikely anyone will ever piggyback on your network. But there’s an easy way to spot squatters: Since every device connected to your network has a unique IP address and MAC address, you can easily see a list of connected devices — often listed as “clients” — on one of the settings pages for your wireless router. Many devices broadcast an ID because they’ve been named by their owners, so if you see “John’s Laptop” connected to your network and you don’t have a John in the house, you’ve found trouble! Even if a device doesn’t show a name in the router’s client list, you can count the number of devices connected and compare to the number of devices you know should be there to see if the numbers are to make absolutely sure no one’s going to figure out your password and worm their way onto your network? You have a few options. Your router can hide its SSID, meaning it won’t show up for anyone searching for connectable networks. The address will have to be entered can also set up a wireless MAC filter to “whitelist” devices you own, disabling access for anyone else. Of course, this makes it a bit tougher for welcome guests, such as friends, to get online at your that still leaves the burning question – what do you do if you think someone is routinely using your WiFi without your permission? If you suspect someone’s stealing your WiFi, you have a number of detective tools at your disposal. For starters, you could simply shut off all of your WiFi devices, like your phone and your laptop – and then watch for blinking lights on the front of your router. If the router seems to be showing data transfer even with your family’s devices powered down, you may have a piggybacker can also smartphone apps like WiFi Thief Detector or for iOS users, WiFi Guard, which help you spot ternet monitoring software is another option. A program such as Wireless Network Watcher lets both Windows and MacOS users keep tabs on all connected devices and potential suspicious activity. When you launch the program, you’ll see your computer nicknames, as well as manufacturer brands of the devices that are connected. If you’re still confused (perhaps because you have so many devices), you can turn off each one and watch as it disappears from the list. If you power down all of your WiFi gadgets and still see active devices, you’re a step closer to identifying a potential you can’t identify a device on your network, simply change the password. You’ll have to reauthorize all of your WiFi devices with the new password, of course, but this is quickest and easiest way to resecure your network and get peace of mind [source: Gordon] long as your network has a strong and unique password, only a hacker using specialized software is going to get past your security. A simple Google search will reveal just how many password hacking resources are available to example, technology site Ars Technica has detailed how a $2, 500 program called Silica can be used in conjunction with websites containing dictionaries of millions of words to connect to a secured network and crack its password. Hashcat is another popular password hacking tool. Like Silica, it’s paired with databases of millions of the most popular password combinations until it figures out the correct password. It works – and it’s extremely easy to do, even for novice hackers [source: Porup] there’s still an effective and efficient way to stop most hackers in their tracks: Use a secure password. The longer and harder to guess, the safer your network will be. With a strong password, you shouldn’t ever have to worry about keeping tabs on who connects to your network. Piggybackers will have to find someone else to mooch off of. Originally Published: Apr 30, 2009

You’ve no doubt heard the warning for years: It’s critically important to secure your home network with strong Wi-Fi security and a password. Without adequate security, neighbors and other strangers can not only steal your Wi-Fi — a service you no doubt pay for— but the freeloaders might also have access to shared folders and other resources on your network.
How to tell if someone is stealing your Wi-FiIf you are concerned that someone might be stealing your Wi-Fi, there are a few tools at your disposal for finding out. Check your Wi-Fi router’s status lightsThe easiest way to see if someone unauthorized is using your Wi-Fi is to look at your router – but this only works if you can take all your wireless devices offline completely. If you have a lot of devices (like smart home gadgets) using Wi-Fi, don’t bother with this approach and go straight to the next. But if you can count all the devices on your Wi-Fi network on one hand, take them offline — either turn them off or set them to
airplane mode. Then watch the status lights on your Wi-Fi router. With no devices using Wi-Fi, the lights should not be flickering or flashing. If they are, someone else is probably connecting to your network.
Use a Wi-Fi detective appThere are a lot of apps available in the app store for your mobile device that promise to scan your network and provide a list of all the connected devices. You can search the app store for options, but one reliable app is called WiFi Guard, available for both iOS and Android. This app gives you a list of all connected devices, which you can scan to see if there are any devices you don’t recognize.
WiFi Guard is one of many apps that can show you a list of all devices using your network.

Many devices will be identified with easily understood names, like your laptop, phone, and some smart home devices. But some may be reported as “unknown device, ” which is relatively unhelpful when trying to determine which are yours and which are interloping.
Use your router’s appIf you have a relatively modern Wi-Fi router, it probably works with a mobile app — in fact, you might have initially configured the router using the app. If that’s the case, you can start the app on your phone and look for a network map, log, or client list. Every router is different and there’s no standardization among router software, so you’ll need to explore. But if you can find this list, it’s essentially an “official” version of the device list from the third-party Wi-Fi detective app. If you have a multiband router, the app will probably even show which radio (such as 2. 4GHz or 5GHz) each device is connected to.
Use your router’s mobile app to look for a list of connected devices.
Log into your admin control panelIf none of those other options are fruitful, your last (and often the most complicated) option is to log into your router’s admin control panel in a web browser. To do this, you’ll need to know:Your admin username: By default, this is almost always “admin, ” though if you practiced good security hygiene, you changed it to something else when you first set up your router. Your admin password: If you have an older router and you never changed the password, this might be hacker bait like “default” or “password. ” Hopefully you’ve changed IP address: Most of the time, your network’s IP address is — enter that address in a web browser and log in if you are offered the opportunity. If that’s not right, you need to find the IP address for your network: In the Start search box, type “ipconfig” and press Enter. Your IP address should be the “Default Gateway. ”
You can find your IP address using the Windows ipconfig tool.
After you’ve logged into your admin control panel, look for a network map, user log, or client list. As we mentioned earlier, every router is different and there’s no standardization among router software, so you’ll need to explore to find it.
How to kick someone off your networkIf you do find an unauthorized device on your home network, there are two simple ways to get rid of them:If you see an unauthorized client in your router’s mobile app or admin control panel, select the entry for that device. You should see the option to block, ban, or eject the device.
You may be able to block devices from your router’s app or admin control panel.
Rather than blocking devices one at a time, you can throw every device off the network at once (including your own devices) by changing the Wi-Fi password. If you don’t already use a password, you should absolutely turn on network security and add a password right now. Even if you already have a password, if someone is using your network and you don’t know how they got access, you should change your password and make it stronger. If your network offers multiple kinds of security, step up to a more secure system, such as moving from WPA or WPA2-TKIP to WPA2-AES.

How to Block WiFi Signal from Neighbors (Simple Answer!)
In this post, you’ll learn how to block WiFi signal from you experiencing frequent WiFi connection interruptions at home? Believe it or not, while the error may be caused by the service provider, it can also be caused by your neighbor’s stronger WiFi signal. Signal interference can cause delays and interruptions for the weaker WiFi signal. This situation is not ideal for professionals working from home and students catching up on academic deadlines. Without having to resort to unfriendly stares or complaints, here’s how you can block WiFi signal from your neighbors. How do I know if my neighbor’s WiFi signal is strong enough to cause disruptions? WiFi signal problems can be multi-factorial. Before jumping into conclusion that your neighbor’s WiFi interfered with yours, you must check with your service provider first or try refreshing your router. If everything seems okay except for your neighbor’s WiFi constantly popping in your range, you may consider it as a potential disruptive you and your neighbor may have different providers, you can expect two competing signals to cause an interference, especially when they are in close range and they overlap. You can tell the strength of your neighbor’s Internet connection by looking at its radio frequency band as it pops in your range. Sometimes the WiFi network’s name visibly says whether it runs on 2. 4GHz (gigahertz) or 5GHz. You can also check the WiFi signal bar and compare it your personal network’s signal. If your gadgets are running on the slower 2. 4GHz frequency, while your neighbor is running on the faster 5GHz frequency, you can expect signal can I block my neighbor’s stronger WiFi signal? Merely adding the network’s name to your device’s block list only hides the network name but does not affect the signal. Here are three ways you can effectively block your neighbor’s WiFi signal:1. Change your router’s placement at simplest way you can catch a good signal is to move your router away from your neighbor’s router. Move it away from side walls and place it in a more central location in the house. Choosing the location would be easier if you know where your neighbor’s WiFi is placed. Otherwise, you will have to try one location at a time, then see if there is any method of repositioning the router works only when the area is not congested. If you live in a complex with tightly packed houses or in an apartment with only walls as partitions in between you and your neighbor, this method may or may not work. But you still have other options. 2. Shift to another are two commonly used WiFi frequencies. The 2. 4GHz frequency has a longer but slower range, whereas the 5GHz frequency has a shorter but faster range. You are wise to shift to 5GHz frequency to avoid signal interference for three, the 5GHz is less common than the 2. 4GHz frequency so in any given area there is a higher chance of less competition. Second, it is shorter in range. Even if you and your neighbor share the same 5GHz, you can conveniently move your router around the house to catch a better signal. Third, it has more channels than the 2. 4GHz range. If you have multiple users using the same frequency, you can shift to a channel with less number of users. 3. Change your frequency’s WiFi frequency has different channels. 4GHz frequency has 11 channels, whereas the 5GHz has 23 (or sometimes higher). At times, shifting frequency is not possible due to router limitations. Before you spend for changing your router, you can first try shifting to another channel. Think of this method as like changing radio channels. To shift to another channel, you must first analyze which channels are most used in your area. There are programs and apps that do the analysis for you. However, you can also do a trial-and-error method. For the 2. 4GHz, the most commonly used channels are 1, 6, and 11, while for the 5GHz’s commonly used channels are 36, 40, 44, and 48. Note that the channels in a given frequency do not always follow a sequential change channels, log into your WiFi network. Type in your router’s IP address onto any web browser, then hit ‘Enter’. If a warning window appears, simply click ‘Advanced’ then ‘Proceed’. You will be asked to enter your username and password. Once logged in, open ‘Wireless Settings’ and click the ‘Channels’ drop-down list. Change from ‘Auto’ to your desired channel, then save changes. You can perform all three suggested methods and you should be able to see an improvement. But just in case nothing works, here are other less conventional ways for you to try:Other alternatives for resolving WiFi interferenceTalk to your neighbor. Respect for privacy often prevents neighbors from asking WiFi-related concerns. This holds for newly moved in neighbors. But engaging in collaborative strategies will help increase your chance of fixing the signal interference problem. For all you know, you are also causing the same problem to them. You can ask for less sensitive information like placement of router, WiFi frequency, and WiFi channel. The information will help you make the necessary adjustments in your home network. If you have multiple neighbors, then you have more reason to talk to them. The signal interference could be thicker concrete walls. This method helps block signals from other sources, although this means you have to spend money for the construction. You may also have to seek permission from your landlord if you’re renting. Jamming your neighbor’s WiFi signal. There are applications that send out blocking signals to your neighbor’s WiFi. But this option is rarely used because in many countries doing so is illegal. You will be fined or sanctioned accordingly. Besides it is only a matter of time before your neighbors find out and when they do this will cause disagreement. Shifting to Ethernet cables. If your task at hand is urgent, you are better off shifting to Ethernet cables. Ethernet connection is immune to signal interference. Laptops have Ethernet ports while mobile phones can be connected to the Ethernet through an adapter. You can easily buy an ethernet-to-phone adapter in any computer shop. Lastly, you should also try reducing the number of devices that are connected to your home network at a time. Turn off WiFi and Bluetooth on your devices when not in use to reduce congestion. Do any or all suggested methods, and you will effectively block WiFi signal from your neighbors.
