How to block a device (Wi-Fi client) on the router by MAC-address?
In this article I will tell you how to block Wi-Fi clients that are connected to your router. Simply speaking, I will show you how to block the MAC-address of a connected device in your router’s settings. Or block absolutely all devices and allow only some of them to connect. It is not strange that the article on blocking access to websites through a Tp-Link router is very popular. It is not uncommon to have to restrict access to the Internet via a router for a device, or completely block it.
Let’s take a detailed look at blocking devices by MAC-addresses on Asus, Tp-Link, D-link and Zyxel routers. This function is implemented in them, but for each manufacturer in its own way. But that’s okay, it’s not hard to figure out. The main thing is that you must have access to the router settings. I will not explain what you can use the lock for here, there are really many options. By the way, you can prohibit to connect to your Wi-Fi absolutely any device: smartphone, tablet, laptop, etc. д.
There are usually two ways you can block Wi-Fi clients:
- Blocking absolutely all devices, no one can connect to your router, and allow only necessary devices (MAC-addresses of the devices). This method is great for additional protection of your Wi-Fi network. Paired with a strong password this makes your wireless network very secure. But if you often connect new devices, this is not very convenient, because you have to write their MAC-addresses every time.
- The second most often used way is to block certain clients from connecting to the Wi-Fi network. For example, you have 10 devices connected to your router at home, and you want to block one of them from connecting to the Internet.
If you want to block a device that is not currently connected to your Wi-Fi network, you need to know its MAC address. If it’s a mobile device, you can see it in the settings, usually under the “About Device” tab, and t. п. If you need to know the MAC address of your laptop’s wireless adapter, you need to run the command line command ipconfig /all. Information will appear, where you will see the Physical address of the wireless adapter. Just do not confuse it with the network card.
Let’s take a closer look at the process itself on different routers. Look below for instructions for your router, and follow the instructions.
What to do if your computer’s IP address is blocked | Your Helper
Written by Elena Molgacheva on January 26, 2013, 19:51 Edited: November 27, 2016, 22:52
The owner of the site for its successful operation and analysis is constantly using various services on the network.
Telling about my achievements and mistakes on the site a year after the start, I have already reported about the fact that I faced with the problem with blocking my IP address. I haven’t been able to access my service for a while.
What to do if they blocked the IP address of your computer? Т.е. Error 403 Forbidden (access blocked) appears when you access a site.
How to get rid of automatic requests if Yandex says “Oops” or Google blocks search?
Scan for viruses.
If this happens to you, then, first of all, you need a good check your computer for viruses. To do this, use an antivirus program that you have installed or install a new one.
Be sure to familiarize yourself with the Google security measures to be followed on the web and choose one of the following antivirus programs.
It is good if you have Google Chrome browser, it provides automatic translation of the page.
Most antivirus programs have, as an option, a free version, or allow you to use the paid version for a certain number of days.
I use the free version of Avira.Many praise the free Chinese 360TotalSecurity.
So you can download and install the antivirus program of your choice and check your computer.
You can also use Yandex tips on how to get rid of automatic requests fixed from your IP address. This is especially relevant when Yandex shows an “Oops” page.
If you have checked your computer and found no viruses (or successfully defeated them on your own or with the help of specialists), then check how you are connected to the network.
How your computer is connected to the network?
If your connection is a local network then go straight to point 3
If your variant of connection is the Wi-Fi router or other similar device, it necessarily should be under the password that strangers could not connect to it. If you have more computers connected to the router, then point 1 (check for viruses) must be performed for them.
Dynamic or Static IP address?
Determine your IP address, for example, by using software to check the speed of your connected Internet. I wrote about this here,
Check with your ISP if your IP address is dynamic or static.
If you have a static IP address, then it belongs to you personally (see point 4).
If you have a dynamic IP adress, then it can change and be given to other people. If you disconnect your network cable (or unplug all the devices that connect you to the network) and stay disconnected for some time, chances are that your former dynamic IP address will be redistributed to another person (device) and you will get a different dynamic IP address when you connect.
Т.е. in the absence of viruses on your computers and any wrongdoing on your part, you may not be guilty of those actions that led to the blocking of the dynamic IP address. It is possible that it was blocked due to the actions of the person to whom it belonged earlier.
If after connecting to the network your dynamic IP address has changed, all the previous blockings will expire, and you can continue working in peace.
If upon reconnection your IP address did not change and remained the same, then you need to write a letter to the administrators of the service (forum, social network) with a request to unblock you. They will check such a possibility and if you have eliminated the reason for blocking, you will be unblocked. In this case you should always provide your IP address, which you’ve defined at point 3.
Emergency temporary connection.
What to do if your IP is blocked and you urgently need to quickly get access to a resource on the network. Let it be temporary, while you are discussing with the administrator of the service which has blocked you.
There is a way out. You can use proxy services, which will intermediate your IP blocking access. You can easily find the people who provide this service by searching for “give me access” or a proxy server. You can access a blocked resource through them if you need it urgently, for example, here http://daidostup.Go to.
Change your location. change your IP address!
Another of the easiest ways to change your IP address is to change your location. Change your geographic location. take your laptop to a cafe with Internet access or to a friend’s house. You will have a different address there.
Access the site from your computer? Try it from your phone. Or vice versa.
Sometimes, even being in the same place, you can get to a resource that is blocked for your computer, from your mobile device (phone, smartphone or tablet). Find out why it happens.
But it is better to contact the administrator and honestly solve the problem, finding out why your IP is blocked. Most likely, you will reach an understanding, and you will resume access to the resource.

Block internet access by MAC-address
Here I will show you how to block Wi-Fi on your TP-Link router.
To access the settings of your NetGear router, type tplinklogin in your browser.Net or 192.168.0.1 or 192.168.1.1 To enter the router‘s settings you will need to enter your username and password. The default username is admin, and the default password is admin.
But you can change the default password for your TP-Link router. How to do it I wrote in the article How to change the password to the Wi-Fi router settings.
After entering the router settings, you will see the main page of the router (status). Here you can see the menu (on the left), the main window (in the middle) and the settings and information (on the right).
Go to DCHP. DHCP Clients List. It shows all the devices connected to our network and using our Internet. You can also see the device names, MAC addresses, IP. Find the device you need and want to block in this list and copy the Mac Address.
Now go into Wireless 2.4 GHz. Wireless MAC Filtering.
Click Add New to add the MAC address of the device you want to block the Internet.
Now type in the MAC Address of the device you want to block on the internet and add a description to this address, just to know who it is. This description will only be here if you have a lot of internet users you want to block internet and you need this description not to confuse the list.
After adding the MAC address and description click Save, to save this address in the list.
Now that we have a list of those for whom we want to block the Internet, click Enable to enable MAC address filtering and start blocking the Internet for those on the list.
Ready. Now everyone on the list will not be able to connect to our Wi-Fi network.
If your router also operates on the frequency of 5 GHz, then enter into Wireless 5Ghz. Wireless MAC Filtering and do the same: add the blocked site to the list and enable MAC filtering.
If you want to remove someone from this list, click Delete next to him. Or if you want to allow everyone on the list to use the Internet, then click on Disable, then the filtering by MAC address will be finished and blocking the Internet for those in the list will end.
Blocking of the website in the router D-Link
Once you are in the router’s interface, click on “Advanced”. “Filter”.
Next, select the “Domain Blocking” checkbox. This is responsible for blocking sites.
After that, you need to check the box next to “Allow users to access all domains except “Blocked Domains. In the special window type in all the sites you want to block and press “Apply”. Do not forget that the same site can be accessed by more than one address. If you want to completely block the site, put all the addresses on the list of blocked.
Your router will restart and then the site you want to block will appear in the “Blocked Domains” window.
Now, when you try to go to a blocked site, an error will appear in your browser.
If you want to remove the ban, select the desired site in the “Blocked Domains” window and click “Delete”.
As you can see, it is quite easy to block a website with a D-Link router. Now let’s study the blocking scheme on other routers.
How to block IP address in your local network?

Full blocking of Wi-Fi network connection by MAC-address on Asus router
If you do everything as I described above, the device will connect to the wireless network, but the Internet will not work. And now we will look at the full blocking by MAC-address. In this case, the device will not be able to connect to your network at all.
In the settings you need to open the tab Wireless. Wireless MAC Filter. Then turn on the filter if it is turned off and under MAC Filtering Mode choose Reject. That means the router will reject the connection of all the devices we add to the list.
Next, from the list of connected devices choose the desired one, or enter the MAC-address manually. And click on the Add button, and then Apply.
That’s it, the device will be disconnected from the Wi-Fi network and will no longer be able to connect to it. Until you remove it from the Blocked List.
If you notice that your network is accessed by someone else, you can simply change the Wi-Fi network password. And be sure to change the password to access the router’s settings.
Firewall On Asus Router. URL Filtering To Block Content
A firewall on your Asus router is a very effective tool for blocking certain devices from accessing the network. In addition to effective network protection from external penetration from the Internet a firewall also performs an educational function. For example, it happens that instead of doing homework your child is so eager to play an online game or watch some. Then it is time to turn on the content filter on your router and use the firewall to restrict access to undesirable web pages on the Internet.
Setting up the firewall on the Asus router
Let’s find out how to manually block sites on the Asus router. The firewall configuration is divided into several steps. Actually, after entering the “Firewall” section in the router’s admin panel, there are a few tabs waiting for us.
Asus URL filter
First, this is to restrict access to certain resources on the Internet. You can add the addresses of sites you want to block access to in the “URL Filter” section.
Here we first check the box to enable the filter and then type in not the whole URL, but only the keyword. For example “XXX”. And all addresses that contain this word will go under the filter, that is blocked sites like “www.xxx18.gu”, “www.russianxxx.CoM” and so on. You can set several conditions for blocking. After that click on the plus sign and apply the settings.
The next tab is a bit more advanced version of blocking web content. The keyword filter function allows you to filter out all sites where banned words appear at least once in the content on the page, not just in the address. Everything else works exactly the same.
Asus network services filter
The last tab in the router’s protection section. “Network Service Filter”. is responsible for completely blocking the Internet or any applications working through specific ports. You can even set up a schedule of days and hours by which they will be blocked. To block the Internet you must specify port “80” as destination.
In addition to the manual settings, some Asus models have a built-in function to block sites through Yandex DNS. read about it in a special article.
What happens if you disable the firewall on your Asus router?
Basically, if you disable the firewall on your router, nothing bad can happen. Just lower the protection of your local network. If some scammers want to hack your WI-FI, they can do it easier than when firewall is on.

Somebody tapped into my Wi-Fi router. What to do and how to block
Hi friends! Today I am going to write an interesting article. I will tell you what to do if you find that someone has connected to your Wi-Fi router and is unscrupulously using your Internet. I will tell you how you can identify and block such a sly neighbor :). precisely, how to determine who is connected to your wireless network, I have already written in an article How to see who is connected to my Wi-Fi router?, But if you have already read my article and found “illegally” connected device, then I will tell you how to block it, so to speak, to cover the freebie :).
And before we get to the technical part, I would like to clarify and explain something.
I wrote in the title of the article “how to block the thief”. I used the word “thief” because I could not find another word :), I kept thinking of the word “thief”. I in no way consider people who use someone else’s Internet thieves. Unless they deliberately hack into somebody’s wireless network, and what thieves they are. they are freeloaders. That’s not a good thing to do.
But excuse me, when I, for example, no router, and my laptop can find at least one, open wireless network, it’s a sin not to connect to it! I think you will agree with me :). By the way, if you do, you might be interested to read the article Connected to someone else’s open Wi-Fi network. Can I be discovered and what will happen?? Nothing will happen, connect and use, as long as the owner of the network has not locked it with a password. True, he probably does not know that his network is open, well, who’s to blame here, let him read my blog more often :).
But today I’m writing from the perspective of a wireless network owner, so let’s get back to the subject.
Let’s start with the fact that if you live in, say, an apartment and your neighbors have laptops, phones, etc. п., If you still have them and you left your Wi-Fi network open and don’t want anybody to connect to it, it’s already a science fiction story :).
You just get tired of blocking these devices, and there is no logic in such actions. Therefore, of course, it is necessary to set a good password on your wireless network, how to do this is written in the article How to Set (change) the password for the Wi-Fi network in the router TP-Link TL-WR841N. The password is of course not 8 units :). The password alone is not enough. That is why you should read the article How to protect Wi-Fi network? Basic and effective tips.
Well, if after such protection you have discovered that someone else’s device is connected to your Wi-Fi router then your network is likely to be hacked, or got into your house and stole the password from the Wi-Fi, or you yourself gave someone the password, and then changed your mind, or Okay, enough :). In short, in any case, you need to block this device.
And imagine the case, someone connects to your network, and you have not changed the username and password to access the settings of the router and is the default. That someone decides to make a joke and lock your computers :). This is no joke. You have to reset the router. Like? It is written in the article How to reset the password and settings on the Wi-Fi router? And if you have a local network is open through a router? Already the information on your computers is at risk.
Block someone else’s device connected to the Wi-Fi router
Of course we will block by MAC-address. And by the way, before blocking, change the password on the wireless network itself and on access to the router settings.
If you have changed the password, then go to the router settings (I hope you already know how) and go to the tab Wireless. Wireless MAC Filtering.
First, you need to enable MAC filtering. To do this click on “Enabled”.
Now you only need to add MAC address of the device you want to block.
MAC address itself is displayed under Wireless. Wireless Statistics, or DHCP. DHCP Clients List (also the name of the device will be displayed on this tab). Actually where you found this device. Copy its MAC address at once (use CtrlC. Ctrl V).
Go back to the Wireless. Wireless MAC Filtering tab and click “Add New”.
Enter the address of the device you want to lock in the MAC Address field. Under Description you can give a description of the device. Next to Status, leave the value Enable. Click on “Save” button.
That’s it, the device will be locked. You will see our created rule. You can remove or modify it by clicking on Delete and Modify. Or you can create another rule by clicking on “Add New”.
Of course, a “thief” can change the MAC address and reconnect to your Wi-Fi network. But I hope you changed the password on your network? As a last resort, you can block all MAC addresses and allow only those devices whose MAC addresses are stored in the router to connect to the router (a good way to secure your wireless network). How to do this, I wrote in How to limit the speed of the Internet via Wi-Fi router? In the example of a TP-Link router, read from the header “What if the client changes the MAC address??”.
That’s all, now you know what to do if you find an unknown device connected to your Wi-Fi router. You block it and that’s it :). I think I wrote everything, I didn’t forget anything.
If you have any questions, Комментарии и мнения владельцев, or additions, please write. Let’s try to solve. It would be nice if you leave a question on our forum, which, by the way, is already running and waiting for new members :). All the best!

In the MAC Address field enter the address of the device you want to block. At Description, you can fill in a description for your device. And leave the Status field set to Enable. Press the “Save” button.
That’s it, the device will be locked. You will see the rule we created. It can be removed, or changed by clicking on the appropriate links Delete and Modify. Or you can create another rule by clicking on “Add New”.
Of course, the “thief” can change the MAC address and reconnect to your Wi-Fi network. But I hope you changed the password for your network? In the worst case you can block absolutely all MAC addresses and allow only those devices with MAC addresses prescribed in the router to connect (a good way to secure your wireless network). How to do this, I wrote in the article How to limit the speed of the Internet via Wi-Fi router? In the example of the TP-Link router, read from the header “What if the client changes the MAC address?”.
