How to Check if Your Wi-Fi is Being Used Without Your Permission

[@Thank_Me_Later]

I think u should make a detailed video on all the major router settings and their functions. That will help the general public to set up their router more wisely 📶

[@303topgun]

Best thing to do is change wifi password to something strong. It’s a pain to reconfigure all devices at home but it does weed out unwanted users

[@arkrainflood]

i simply log into my router then see which devices are connected. there is an option in the network tab to block any i do not want

[@vasudevmenon2496]

MAC address blocking is great if MAC randomisation is disabled otherwise it's better to change password. It's better to set WPA3/WPA2 AES with limited band options ax,ac and n so that attackers can't downgrade to lower standard to exploit a known vulnerability. If others have already logged in without your knowledge the network is compromised and one must hope they don't have access to router and block the owner from changing anything

[@UltraZelda64]

Just set up static IP addresses for primary/known network devices in the lower IP address range and set DHCP to use the higher addresses for everything else. If anything questionable connects, it will be in the higher range. If someone is leeching, there are three options: 1) Go scorched earth: Change your password. IMO this is a last resort unless multiple people are connecting without permission or causing real problems with the network. Requires changing the password for literally *everything*. That's over 70 different devices in my case, it's best to not have such a problem that this is even required in the first place. 2) Block individual MAC addresses. Sure, MAC addresses can be spoofed, but I doubt many people know a thing about it. Keep monitoring your network to make sure. 3) Block all MAC addresses by default and create a whitelist for allowed network devices.

[@MrPir84free]

Most phones, computers, tablets are by default set to change the MAC address upon each new connection; it's a default for Windows, Android, Apple IOS, etc. It does not take much to grab a MAC address from another device on the network and thus circumvent the entire scheme, but you are right in that most would not know how to implement a spoofed IP to gain network access. Blocking individual MAC addresses is nearly pointless; blocking all MAC addresses by default and only allowing a whitelist does work but is generally a pain to maintain. In truth, I do on occasion block an individual MAC address in order to track down a device that I forgot about; but then unblock it once I am sure that it's mine. Setting static IP addresses is also a PAIN to implement, but is done more easily in the router by setting a DHCP reservation and if you're lucky your router will allow you to pick IP's outside of your DHCP scope. IF anyone finds someone else leeching their internet, the "owner" of the wifi really should be concerned. While some cases only consume bandwidth, if the abusers go to the wrong sites, or their conduct is illegal, well, authorities are going after whomever legally owns that IP/WIFI; scorched earth is what you should indeed implement if one notices someone else on their wireless network. The biggest issue for most is maintaining a list of IP's with the associated MAC addresses for their allowed devices. I'm surprised you didn't mention bandwidth throttling, which is a feature on some routers..

[@TheWobblyFace]

Very useful Brian, thanks. I have quite a complex password plus MAC filtering.

[@An.Individual]

make sure you're using WPA2 or WPA3. MAC filtering won't stop a hacker but a complex password should

[@MrPir84free]

@@An.Individual If all of your devices support WPA3, you should configure your router for only WPA3. Most IOT devices do not support WPA3, thus require WPA2/WPA3 setting ( as on most new, up to date routers ). Ideally, your IOT devices would be set on your IOT device network, or the GUEST network if your router does not have one, and set for WPA2/WPA3. On your home network for your normal devices, if possible, set it to use WPA3 only; Generally speaking, Guest / IOT devices should not be given access back to the home network and only given Internet access IF required. You are indeed correct on a complex password, but it should also be longer than 8 characters, complex, and ideally longer than 15 characters or so if possible. Another type of password can also be considered, and that's a pass phrase where one uses 2, 3, or 4 or more usually unrelated words for a pass phrase. I.e. Chevrolet_Montana_Squirrel or Peter.Mayflower.Maple.Engine or Jerry Lives in Bugtussle VA or TheTrafficOnThe101InTheMorningIsBad! ... To separate the words, one can use various symbols, spaces, or nothing; the words should generally be random in nature. Generally speaking, the longer your passphrase, the better; up to a reasonable point. If you have more than one SSID, like a normal SSID + a guest network, use a different password/passphrase for each.

[@user-sd1xp4fr5o]

This video seems helpful, however I can't follow all your steps because I don't know anything about my router or how to operate it. It would be helpful if you could make another video about it, especially for Windows 10. Thanks.

[@cpuuk]

What a coincidence, I was just doing that very check today.

[@Dennis-ur4zu]

thank you for the upload. in my case i just turned off 2.4ghz. too much range for strangers to play around

[@Shin-Shoryuken]

Thank you. Can you do a similar video about securing your modem router and online banking/shopping.

[@tearren1]

I would suggest trying to disconnect the device in the router first before blocking. I didnt recognize a device and so disconnected it, and it turned out to be one of my own devices with a weird name. Im not sure how easy it is to unblock devices, maybe its simple though.

[@defan2105]

Brian, great video. I have changed my passwords but they simply figure it out again no matter how complicated I make it. I would hide my name but then my (for example) Amazon TV will not connect until I un-hide it even if it knows the password. Any idea on what to do? Local internet provider (the only one available) is basically in a "sucks to be you" reply for assistance.

[@MrPir84free]

Hiding the SSID name does almost nothing; especially when you consider that every device that connects to it sits there broadcasting the SSID while trying to connect to it, literally screaming the name of the SSID that you attempted to hide. BTW: You probably have an issue with your WiFi router and should consider either updating its firmware or just replacing it. What you are attempting to do should work; but that may also be an issue with Amazon TV ( update the software for it perhaps ) or change the router ...

[@rager1969]

Understand that iPhone and iPads will change their MAC addresses, so if you block something, it may reconnect later with a different MAC address. This feature is to protect you from being tracked as you roam past (or connect) to different SSIDs (WiFi networks) when you're out and about. If you are able to allow only certain MAC addresses to connect (and block anything else), you can change your iPhone and iPad to not change the MAC address for particular SSID(s), this staying consistent at home, work, etc but change the MAC address everywhere else.

[@Tom-sg4iv]

Android does as well

[@erfelgamazig]

Hello, and thanks for your video! I downloaded the 64 bit version, saved it my computer, and tried scanning it with an online scanner. It said "ERROR" because it is password protected. I tried opening it with WinRar, and Windows Defender found 2 high dangerous trojans or viruses (it didn't say which) Which one are you using??

[@GeordiLaForgery]

Thanks Britec. Unrelated but should your IP address geographical location always be fairly accurate?

[@ojas3464]

Depending on the location, it may be advantageous to disable broadcat

[@helsnonya2633]

My neighbour is doing man in the middle attacks. I have tried blocking him but he just piggybacks on the same MAC address of my Ring device. Any way you could do a video on that?

The built-in console on your wi-fi router can show the users accessing your network. User passwords can also be changed via the console. I was wondering about the MAJOR difference between the built-in console and your recommended app monitoring wi-fi activities.

[@Nodster]

The only real convenience the app has is probably the constant scanning of the network while the app is running otherwise there is no real difference but most people probably don't know how to access the router interface let alone what the router does, to them that is probably some magical device that sits in the corner that makes the internet work lol

[@zer0r00t]

Or simply use whitelisting and only allow your own devices

[@warp00009]

The huge problem with changing your wi-fi password is then having to reset and reconfigure every legitimate device in your environment. Many of the devices that I have, like home security cameras, will require physical access and a manual process to do that - which makes it realistically impossible. My non-ISP router will easily show all the clients connected, so no additional software is needed to determine what's there - although sometimes it's hard to associate a particular connection with a physical device.

[@EEDSPELL]

To have security cameras and smart devices connected to the same network as your regular home equipment will provide a major risk to be hacked. If not spending the time to secure your network based on pure convenience matter, then this is the same risk level as locking a door and leave the key in the lock or under the door mat.

[@Nodster]

@@EEDSPELL you are over playing the idea that people's home networks are going to get hacked by some rando sitting in a van outside their house, The likelihood of people's home networks actually being hacked via wifi is quite slim in reality unless they do not have a strong password or a password at all (my neighbours for example heh) Most network attacks are going to come from the internet and not the guy in a van outside the house, at that point only one piece of information is required for a determined hacker to gain access to your network/s and that is the external IP of your network and at that point your multi-network setup means nothing in reality (just like leaving your key under the door mat) The reality here is that all our details are more likely to be compromised from major sites like Facebook etc than they are from our own networks as those are much bigger targets and at that point the mistake the majority of people that are not technology/internet savvy make is having weak password and/or re-using passwords. Most people do not have the need or wan't to learn about network security let alone how to setup multiple networks and you might as well be talking another language at that point really. The only real advice that can be given to the masses is about password security and it's effectiveness and even then we sit between a rock and a hard place given how convenient using the same password for everything is or using an easy to remember password is.

Passwords should be complex in nature, comprised of a number of various characters, and different case, and ideally the longer the better, like over 15 characters long Another type of password can also be considered, and that's a pass phrase where one uses 2, 3, or 4 or more usually unrelated words for a pass phrase.

reasons why when you hack someones network, you clone one of devices and this way you overlap and are invisible

[@keylanoslokj1806]

Is there a countermeasure for this?

[@UnknownUnrecognized]

@@keylanoslokj1806 yes:) but it takes more work and testing current user to discover a cloned user... takes some skills and knowledge and time, sometimes you work on it and discover nothing because clone has disconnected, then if you have forensic skills maybe you can check what happened if the attacker does not care about trails left behind

[@Britec09]

Once they connect they leave a trace.

[@dingokidneys]

When your router gives a device an IP address, that address is valid for hours; maybe up to 24 hours. It's called a DHCP lease time and you may be able to change that on your router though reducing it too much might cause annoying lag as your devices renew their leases. So if you connect a device and then turn the device off, the lease will still show up on your router until it expires.

[@williamjones4483]

You can also log into your wireless router/modem and it will show you all devices connected.

Don't you just hate it when your neighbour switches off the router before they go to bed?

[@brucelee3388]

One possible catch, if you are not at the site full time, is for the scammers to just turn your power off at the switch board for a few minutes - then the router & WiFi will reset to their default passwords if they are not on their own UPS. It will be obvious once you get home because most plug in clocks and appliances will also be flashing too, but the scammers will have had access while you were away, which could be several hours or even days, and all that malicious activity will point to your site as the source.

[@alfredbester.psycorps]

That is complete bs. Turning off the power will NOT reset a router to factory defaults.

[@Nodster]

This has not been a thing for a very long time if at all as all the routers I have used over the years have had some form of memory to keep the settings applied after power cycling the device, even for the two weeks mine was unplugged last year :D If your router is forgetting it's settings after a power cycle you might want to get it repaired or replaced as that is not the norm these days. Also what are you even talking about here? scammers turning the power of at the switchboard? If the "scammer" has access to the power switch then they surely have access to that UPS power switch you mention to turn that off too? Also if a "scammer" has access to the property while you are not there to give them access to the property would this not be breaking and entering? Also also this video literally has nothing to do with anything that your comment responds to and certainly not about gaining physical access to the router like your response suggests.

[@Tom-sg4iv]

Might not all be malicious. I "borrowed" my neighbours wifi for a smart switch so I could power cycle my router remotely when it became unresponsive 😂

"Rooter" (what you say in the video) Definition: It can refer to a device or tool that is used to clear or remove blockages in pipes or drains, commonly called a plumbing rooter or drain rooter. It may also refer to someone or something that "roots" or digs, such as an animal that searches for food in the ground. "Router" (the word you should say in this video) Definition: A router in computing is a device that directs data traffic between networks, typically managing internet connections in homes or offices. In woodworking, a router is a tool used to hollow out or shape areas in wood or other materials.
