Suggested March 2024 How To Kick Unwanted Connections Off Your Wi
If you are trying to surf the Web and experiencing slow network speed due to bandwidth congestion, it’s probably due to too many devices connected to your router. Chances are, some of these devices are not yours. Once you share your Wi-Fi password with someone or log on to your Wi-Fi on someone else’s device, the password remains with them. It opens up the possibility to log back in to your Wi-Fi connection without your permission. Unwanted connections can pose several security and privacy threats, so it is a good practice to keep filtering the connected devices on your Wi-Fi.Why Disconnecting People from Your Wi-Fi Is a Good Idea
Having unwanted people sharing your Wi-Fi connection has the potential to whip up some serious problems. Someone with the wrong intent and skillset could steal your personal information if they gain access to your private network.
It also opens up the potential risk of compromising your webcam and microphone, which can put your privacy at risk.
Also, having more people connected to your network can cause bandwidth congestion, which can slow down your Internet speed. Additionally, if you are on a limited data plan, you might suffer unwanted charges for the data they have consumed.Find Your Router’s IP Address
Before doing anything, you need to know the address to access your Wi-Fi router’s admin panel. In most cases, it’s one of the following:
However, to find out which one’s yours:
Search for “CMD” and run Command Prompt as admin.
Enter the following command: ipconfig
Command Prompt will print out a bunch of information about your network. Find and copy the default gateway address from here.
Enter the default gateway address in your browser’s search bar to be redirected to the admin panel of your Wi-Fi router.3 Ways to Remove Unwanted Connections from Your Wi-Fi Network
Now that you know your IP address, you can remove unwanted connections from your network with one of the three methods below:1. Use MAC Filtering
Every device that connects to the Internet has a 48-bit address associated with it, which is known as a MAC address. Use this MAC address to identify and block certain devices to connect to your Wi-Fi network.
To do that, you need to access your Wi-Fi’s admin panel and navigate to the tab where all the connected devices are listed. You can see all the connections, along with their details. In some cases, these details also include the MAC address of the connected devices.Find Your MAC Address
All routers do not use the same software, so you may only be given the device’s IP address. Luckily, we can easily find the MAC address of a device using its IP address and a few commands. Follow the steps below:
Type the following command: ping "IP address"
After a few print statements are displayed, enter the second command arp -a
The ARP command lists detailed information about the device you targeted via its IP address. The MAC address will be mentioned next to the device’s IP address. In this example, the IP address is 192.168.0.1, and the MAC address is 50-2b-73-87-a3-20.Use the MAC Address to Block Unwanted Connections
Now that you have the MAC address of the device you want to block from your Wi-Fi network, head back to the router’s admin panel and follow the steps below to blacklist it.
Navigate to the MAC address filtering section. Where you will find these settings depends on your admin panel’s UI. Most of the time they will be in the Security or Advanced settings tab. In our case, it was in the Advanced tab.
Set your Filter Mode as “Blacklist” (at the top).
Enter the MAC address of the device you want to blacklist in the “Blacklisted MAC Address” field and add it to the list by pressing on the “+” button underneath “Operation.”
Make sure to save your changes before closing the tab by pressing “OK.”2. Only Enable Whitelisted Devices
While blacklisting a device completely bans it from connecting to your network, hackers can always join back in using another device. To prevent such a situation, a much more secure approach would be to whitelist the MAC addresses of select devices.
Basically, you can tell your router to only allow certain devices and automatically block any other connection requests. Here’s how to whitelist your trusted devices.
Navigate to MAC address filtering options on your router’s admin panel and select the whitelist option instead of blacklist. This step may not be the same for you, as every router has a different UI, but the concept remains the same. With some routers like those of D-Link, you get another section of settings dedicated to whitelisting devices instead of a switch between the two functions.
Just as we added a MAC address in the field below to blacklist it, enter the MAC address of the device you want to whitelist and add it to the list by pressing on the “+” button on the right. Alternatively, you can select the “Whitelist all the online devices” option.
Finally, save the changes you’ve made, and only the devices added to this list will be able to access your Wi-Fi network.3. Change Wi-Fi Password or SSID
If you don’t want to go through the hassle of blacklisting or whitelisting a device, you can simply change your Wi-Fi’s name or password. All the devices connected to your network will be automatically logged out. Reconnect your trusted devices by entering the new password.
Head to your router’s admin panel and navigate to the settings menu to find the option to change your Wi-Fi’s name or password. In most cases, these settings are in the Security tab or the WLAN settings section.
To change your Wi-Fi’s name, simply enter a new name in the Wi-Fi name box. You can set different names for your 2.4GHz and 5GHz band.
Save your settings to finalize your changes by pressing “OK.”Frequently Asked Questions 1. What is the best security encryption for my Wi-Fi?
WPA3 is the latest and most secure Wi-Fi encryption protocol available in 2023. Do note that many Wi-Fi routers don’t yet support it.2. How can I identify if someone is using my Wi-Fi without going through the router admin panel?
There are many ways to tell if someone has unauthorized access to your Wi-Fi network:
If you are experiencing poor speed, it could mean that your broadband is being stretched over multiple devices. If the speed doesn’t increase even after you disconnect all the devices from your end, it could very well mean that someone else is using your Wi-Fi network.
High latency while playing online multiplayer games or connecting over a video call.
If your Wi-Fi is rebooting multiple times by itself, it could mean that someone else is trying to brute-force their way into hacking your network.
If your Wi-Fi network does not display WPA protection anymore, it could mean that it has been compromised and that someone is already inside your network.3. Is there software that I can use to monitor the devices connected to my network?
There are many software you can use to kick an unknown device off your Wi-Fi networks, such as JamWiFi or Netcut. But these apps are only temporary solutions and the same as executing a simple Wi-Fi de-authentication attack, which does not permanently ban someone. However, it can log them off temporarily.

Last November, EarthLink announced it would not make any further “significant investments” in its muni wireless business and that it would “begin a process to consider its strategic alternatives.” Yesterday, the company announced that the alternative it has settled on is to sell off the business altogether. The news came when EarthLink released its Q4 and Full Year 2007 financial results.
While the company has committed to a plan to sell its muni wireless assets, which it values at $40 million, as yet, there are no takers.
The move did not come as a surprise to industry watchers, as EarthLink CEO—and newly elected Chairman of the Board—Rolla Huff has been clear about EarthLink’s declining interest in funding a venture that, while successful by some measures, was not producing the ROI stockholders were looking for.
“After thorough review and analysis of our municipal wireless business we have decided that making significant further investments in this business could be inconsistent with our objective of maximizing shareholder value,” said Huff, in a press release last fall.
In a press release issued yesterday, EarthLink made the decision to sell official.
Phil Belanger, a founding member of the Wi-Fi Alliance, who’s company, Novarum, has done extensive testing on many of EarthLink’s muni Wi-Fi networks, says its not the technology that failed, but rather the business model.
“I think that everyone has already concluded that the EarthLink-style model of building Metro Wi-Fi networks primarily for commercial public Internet access and residential broadband is not viable—particularly in large cities with competitive broadband alternatives. So, this is nothing new for the industry. It is simply the other shoe dropping. Municipal wireless networks are still being built, but the successful ones support multiple applications—usually private city applications with a commitment from the city to buy a minimum level of service,” says Belanger.
In terms of who might buy up the EarthLink assets, Belanger says it will likely vary city-by-city.
“In general, the EarthLink muni networks are competently built. So, there are reasonable assets in place that someone could leverage for a particular application. The Philadelphia network provides fairly good coverage outdoors. It could be converted to a public safety network. If the city could get a good deal on the current infrastructure they would not have to invest much more to optimize the network for public safety.
“Ironically, Comcast or Verizon may also be interested in the Philly network. Comcast, in particular, could leverage its cable plant to provide more wired backhaul and increase the performance of the network dramatically. But, they won’t go near it if they have to assume the contract liabilities.”
Muni/metro wireless expert, Craig Settles says the key to success will be for local governments to leverage the networks to meet their own needs.
“Everything depends on how clear your vision is,” says Settles. “There are many local governments actively working to make the business case for a network to serve primarily mobile government workers and asset management, plus key constituent groups, such as the medical and university communities. Given this, if I’m a service provider that can embrace the vision of meeting that government need, then it might make sense to buy the EarthLink business. Everything depends on the price and what you get for your money.
“I think EarthLink’s position that there’s no money to make with muni wireless is true, to a point, if the only thing you want to do is sell a general consumer service. Anyone who buys this business with that in mind is likely in for trouble. But muni wireless as a local government resource, that you can take to the bank.”
EarthLink has publicly committed to continuing to work closely with the municipalities it currently serves. And, according to Settles, Philadelphia, the most prominent EarthLink muni customer, has been expecting this all along and has a contingency plan in place.
“Philadelphia’s CIO has planned for this development,” says Settles. “He views that city’s network as a potential invaluable resource. They have nearly 3,000 mobile government workers, 300 city-owned facilities located throughout the city, a large number of mobile assets such as vehicles, and probably a larger number of fixed assets, such as parking meters. The network significantly benefits improving communication capabilities and management of all of these resources.”
While the money-making end of the business seems not to have worked out in EarthLink’s favor, the deployments have outshined other deployments—including WiMAX.
“For the past several months we have been testing Clearwire fixed WiMAX deployments, as well as the metro Wi-Fi deployments, for our Novarum Wireless Broadband Review,” says Belanger. “With the right client device, the EarthLink network out performs the typical Clearwire network. So, the technology and implementation is competitive and not obsolete in any way. If deployed in a market that is lacking in other broadband alternatives (like most Clearwire cities) the EarthLink networks can deliver a competitive commercial service. In Philadelphia? not so sure—there are many alternatives (with prices that dropped since the EarthLink network went in).”
While EarthLink hasn’t yet indicated if it will break up the assets and sell them city-by-city, given the size of its Wi-Fi-related losses (roughly $80 million last year compared to $20 million the year before), it seems likely that regional deals will emerge.

Is your iPhone, iPad, or Mac constantly connecting to a known Wi-Fi network that you don’t want it to connect to? Sure, you can easily forget that network and put an end to this. But what if you wish your device to remember the Wi-Fi network (so you don’t have to enter its password again) but just doesn’t automatically connect to it?
In this tutorial, we will learn how to set your iPhone, iPad, Apple Watch, or Mac to prefer one Wi-Fi network (the faster, better one) over another (the slower one).Multiple known Wi-Fi networks (or 5 GHz and 2.4 GHz wireless bands)
Recently, I got a new internet connection and a dual-band router that offers both 2.4 GHz and 5 GHz Wi-Fi. As a result, when I go to my iPhone or Mac’s Wi-Fi settings, I see two Wi-Fi networks – Ankur T (2.4 GHz) and Ankur T_5G (5 GHz).
2.4 GHz Wi-Fi uses longer waves which offers an extended range and better transmission. Thus it will efficiently work even if there are multiple walls and obstructions between the device and the router. However, this band offers slower speeds. Plus, almost all Wi-Fi devices, like smart accessories, appliances, garage doors, etc., support this band, due to which it’s congested and can drop connections.
5 GHz Wi-Fi uses shorter waves that have difficulty transmitting through walls, etc., and offers a smaller range. But, as far as speeds go, it’s far superior to the 2.4 GHz Wi-Fi. Plus, not all devices support the 5 GHz band, so it’s less congested and doesn’t drop connections.
In my home, the download and upload speeds offered by the 5 GHz Wi-Fi are at least two times faster than the 2.4 GHz one (image below). Plus, since it’s a small apartment, I don’t have to worry about range and thus want my iPhone and Mac to always connect only to the 5 GHz band and ignore the other.
Earlier, whenever I would come home from outside, the router restarted due to a power outage, or I restarted my devices, they would prefer the 2.4 GHz Wi-Fi and automatically connect to it. The experience was kind of annoying to manually switch to the 5 GHz Wi-Fi every time.

Similarly, in my previous office, there were five Wi-Fi networks. My Mac would always auto-join the slowest one, and I would have to manually connect to the better network every morning. Small inconvenience, but no one likes doing this daily!
Thankfully, the steps below solved this issue forever!Auto-join a better Wi-Fi network over another iPhone and iPad
Follow these steps to set your iPhone to prefer a better Wi-Fi network and automatically connect to it rather than connecting to a slower network:
1) Open Settings and tap Wi-Fi.
2) Tap the info button (i) next to the slower Wi-Fi network.
3) Turn off Auto-Join.
4) Go back to the previous screen and choose the info button next to the faster Wi-Fi network.
5) Make sure Auto-Join is enabled for this.
From now on, when you enter this area with both known Wi-Fi networks, your iPhone will always automatically join the better Wi-Fi. Goodbye, slow speeds and connection drops!
Anytime that better Wi-Fi is unavailable, you can simply tap the other Wi-Fi network name in Wi-Fi Settings or the Control Center (after pressing the Wi-Fi icon) to join it. You don’t have to type the Wi-Fi password.Apple Watch
Apple Watch Series 6, Series 7, and later can connect to both 2.4 GHz or 5 GHz Wi-Fi networks. However, Apple Watch Series 5 and earlier, and Apple Watch SE can only connect to 2.4 GHz Wi-Fi.
This is how you can set your Apple Watch to prefer joining one Wi-Fi network over another:
1) Press the Digital Crown and tap Settings.
2) Select Wi-Fi.
3) Choose a Wi-Fi name you don’t want your watch to join automatically and turn off Auto-Join from the next screen.
4) Now, go back and tap the preferred Wi-Fi name and ensure its Auto-Join switch is enabled.
From now on, your Apple Watch will automatically connect to the Wi-Fi network you choose in step 4 and ignore joining the other poorer Wi-Fi.Mac
Here’s how to set your Mac to prefer and auto-connect to a faster Wi-Fi network than another slower option:
3) Uncheck the Auto-Join box next to the inferior Wi-Fi network.
4) Make sure the Auto-Join box next to the superior Wi-Fi network is checked.
Tip: On this screen, you can drag the Wi-Fi network you want to give the highest priority to the top of the list. After this, your Mac will give preference to the Wi-Fi network that’s on the top of the list and try to join that. In case it can’t join that network, it will move on to prefer the second available Wi-Fi network and so on.
That’s it. From now on, when you enter this area with both known Wi-Fi networks or power on your Mac, your computer will automatically join the better network. No more hassle of manually connecting to a faster network every time!Wi-Fi auto-join preferences
This is how you can set your iPhone, iPad, Apple Watch, or Mac to prefer one network over the other.
Besides speed, there are other instances where you might have to prefer a network over other. For example, you can control your smart bulb from your iPhone when both are on the same Wi-Fi network. If you have multiple Wi-Fi networks, you can use the above steps to ensure your iPhone always connects to the network that your smart appliances are connected to.
In this tutorial, I demonstrated using two Wi-Fi networks. But if your house, school, dorm, office, coffee place, or another frequently visited area has several networks, follow the same steps to prefer one over the rest. Just keep auto-join enabled for the best, fastest Wi-Fi, and turn off auto-join for the rest.
I should remind you once again that turning off auto-join for a known Wi-Fi doesn’t remove its Wi-Fi password. Your device still remembers the network, and you can manually connect to it in the future without entering the password.

Wi-Fi connection problems are pretty frustrating. Maybe it’s just me, but they always seem to happen at the worst time — like during an important Zoom meeting. You’re not alone if you have problems connecting your Android smartphone to a Wi-Fi network. In this post, we’ll look closely at a few fixes that might solve your connectivity issue and get you back online if your phone won’t connect to Wi-Fi. Let’s dive in.
What to do if your phone won’t connect to the internet:
Editor’s note: We’ve assembled these instructions using a Google Pixel 7 running Android 13. Remember, some of these steps may differ, depending on your device and the software running.
Restart the phone

Tap on Check for update.
Your phone will let you know if there is an available update. Follow the instructions to update.
Reboot your router
Edgar Cervantes / Android Authority
It’s possible that the router is to blame for your connection problems and not your smartphone. This happens often enough and is yet another easy fix in most cases. Just unplug the router from the power outlet and wait for at least 30 seconds before you plug it back in. Many routers also have a restart button. After that, you’ll have to wait a minute or two for the router to turn back on. Once it’s set up, try connecting to the network again to see if things work as they should.Forget the Wi-Fi network and reconnect
Forgetting the network and reconnecting to it is the next solution that might solve your problem. To do this, open the Settings, tap into Network & internet, and select Internet. Under Wi-Fi, find the network you want to forget and tap on the gear icon next to it. Hit Forget. Tap on the same network and enter the credentials to reconnect.How to forget a Wi-Fi network on Android:

Your Mac can be made to power on and shut down on a custom schedule. Having your computer start up 15 minutes or so before you get up from bed in the morning is a great way to have your emails, photos, messages, calendars and other personal information items updated and refreshed before you even touch the keyboard. This helps reduce the time necessary to wait to use the machine.
Conversely, you may want to set your Mac to shut down at a specified time rather than sleep in order to save power. For instance, my custom power schedule is set to automatically shuts down my MacBook Air about half an hour after I finish working on workdays.
You can use the scheduling feature in your Battery settings to set a time for your Mac to automatically start up, wake, sleep, restart or shut down. This step-by-step tutorial will teach you how and why to set up a custom power schedule in macOS and when it might be more convenient to put your Mac to sleep instead.How to use power scheduling in macOS
You don’t need any specific macOS version in order to use the power scheduling feature because it’s built into virtually every version of Apple’s desktop operating system.
1) Open System Preferences from the Dock, the Applications folder, the Apple menu, or Spotlight.
4) Now create your custom power schedule:
Start up or wake—Tick the top checkbox and choose a day or group of days from the pop-up menu, then enter a time.
Sleep, restart or shut down—Tick the bottom checkbox and select Sleep, Restart or Shut Down from the pop-up menu, then choose a day or group of days from the pop-up menu on the right and enter a time.
6) Close out the System Preferences window.Important caveats
In order to shut down automatically, you must of course be logged in to your Mac.
Furthermore, the computer needs to be awake at the time that it’s scheduled to shut down and remain awake for at least ten minutes past that time.
If your computer happens to be sleeping at its scheduled shutdown time, it will continue sleeping instead of shutting down. Similarly, if you’re logged out (i.e. you’re at macOS’s Login screen), your Mac also won’t shut down.
TUTORIAL: Picking apps to launch automatically when your Mac starts up
If your Mac is set to go to sleep after less than 15 minutes of inactivity, it might go back to sleep before macOS has finished shutting it down. To ensure the system shuts down even when it’s sleeping, set it to start up or wake 5 minutes before your scheduled shutdown time.
Also, having any documents open with unsaved changes may prevent a Mac from going to sleep or shut down when scheduled. And lastly, if you’re going to make your Mac start up on a schedule, be sure that it’s connected to a power adapter.Shutting down vs. sleeping
While some people will find it more convenient to just put their Mac to sleep when it’s not in use, shutting it down at the end of the day not only saves more power than the sleep mode, but also give it a chance to install pending updates that require a restart, flush the caches and perform other housekeeping operations as part of the general maintenance routine.
As I mentioned earlier, you may want to use power scheduling in macOS if you want to be sure your Mac turns off when you aren’t working and turns on before you come to work.Need help? Ask iDB!
