How to find out who is connected to my wifi. We get a list of all connected devices in the program. Maximum number of devices over Wi-Fi

I'll try to answer today interest Ask which I think a lot of people are interested in. Let's try to figure out how many devices can be connected to the router at the same time. By wireless Wi-Fi network, and by network cable.

how many different computers, phones, tablets and other equipment, you can connect to one router, how it will affect its operation, and whether it will work at all.

Let's get straight to the point. And, first, let's deal with connecting devices via a LAN network cable. As a rule, in ordinary modern routers, there are 4 LAN connectors. Here, for example, I have a TP-Link TL-MR3220 at hand, now I'll take a photo of the LAN connectors.

This means that you can connect 4 devices to it. For example, a computer, or a TV over a network cable.

It will not be possible to connect more devices, as there is a limitation on connectors. This, I think is clear.

It's more interesting here. There is no physical restriction when connecting via a wireless network. Compared to network connectors.

But, this does not mean that you will connect 20 laptops to the router and everything will work fine.

Yes, there is a limit. And, I think this is the maximum number of IPs that the DHCP server on the router can give out. For example, by default, Asus has an end IP address 192.168.1.254 :

And Tp-Link, for example, 192.168.0.199 :

It turns out that, for example, 99 devices can be connected to Tp-Link, and more than 250 to Asus. But, I think that these numbers mean nothing in practice. At all. This is theory. If I'm wrong, please correct me.

I think that not a single router, even the most modern and powerful one, can withstand 99 devices. He simply cannot physically provide them with access to the Internet. Moreover, stable access.

I didn’t have to test it, but I think that if you connect even 10 devices to the same popular TP-Link TL-WR841N and start downloading something, or open sites on them, it will simply “freeze”. The Internet will disappear everywhere, and only a reboot will save it. He, the processor simply can not withstand such a load. Even if you run games on several computers, I'm not sure that it will keep the connection stable. Even a torrent on one computer can load the router. I already wrote how to deal with this “Problems with uTorrent when working through a Wi-Fi router: the connection is lost, the router reboots, the Internet is slow“.

This applies not only to TL-WR841N, or TP-Link, it applies to all routers. If, for example, we take his younger brother TL-WR741N, then things are even worse there (it is cheaper and weaker). Very often I meet complaints that the Internet simply stops working. Only a reboot saves, and then, not for long. This is a vivid example of the fact that the router simply cannot withstand the load that the devices that you connected to it create.

If we take more expensive models, for example Asus RT-AC66U, TP-LINK TL-WDR3600, then the situation with the number of simultaneously connected devices and network stability will be much better there. Since, these models are much more expensive and more powerful. They have more powerful processors, power supplies, etc.

And mobile 3G routers (almost all models) have a restriction on connecting devices via Wi-Fi. Usually, this is up to 5 devices. For example: Huawei EC 5321u-1 Rev.B, Sierra Wireless AC802 - up to 5 devices. But to Easo M8 - you can connect 50 devices, but 5-7 are recommended. It is clear that he will never pull 50 devices.

Afterword

When choosing a router, you should already know approximately how many devices you will connect to it. If you have, for example, two computers and several smartphones, then you can take not very expensive model, such as the TL-WR841N, or another in this price range.

But if you want to build wireless network in a large house (where there are a lot of devices), in a small office, a hostel, etc., then I advise you not to save. Take a router that costs more than 1000 UAH. (4000 rubles). So that everything works stably and without failures.

Otherwise, the Internet connection will begin to disappear, and you will be looking for an answer for a long time and tediously why this is happening. And the answer will be very simple, it's just that your router will not withstand the load that the devices will create. Especially if you are going to play Online Games, watch video in high quality, or download (distribute) torrents.

I will be glad to see your questions, comments and additions in the comments. Best wishes!

To the point WiFi access you can connect a large number of client devices (hereinafter, we mean simultaneously connected). The exact figure depends on the device limitations, if any (for example, MikroTik has a software limitation of 2007 clients).

However, in most cases, connecting such a large number of clients is not recommended due to the peculiarities of the Wi-Fi protocol itself (i.e., not due to any weakness of the access point). This is due to the fact that common client devices (laptops, smartphones, etc.) work directly according to the standard (any of the 802.11 family) and do not support * any special polling mechanisms / protocols (such as airMAX, NV2, iPoll and etc.), "accelerating" the operation of the radio network. Without such mechanisms, with a large number of clients, the overall ** data transfer rate is noticeably reduced, the delay increases, etc., because need RTS/CTS negotiation, retransmission in case of collisions***, etc. The decrease in performance appears already at the appearance of the second client and continues with the appearance of each additional client.
* because the 802.11n standard itself does not regulate them
** is shared between all clients, because Wi-Fi uses a half-duplex medium
*** because RTS / CTS is not a panacea, especially in the presence of interference (due to reflections and interference) and physical obstacles in the path of the radio signal

In general, the "hardware" performance of the access point can also act as a limitation on the number of connected clients, but in this respect it all depends on the specific situation:

  • access point performance (speed of code software and, most importantly, the performance of its hardware)
  • access point capabilities in terms of radio communication (availability of support for MIMO technology, several simultaneously operating ranges (radio modules), large channel width, short guard interval, high modulations, etc., see article)
  • opportunities specific models client devices (availability of MIMO technology support, large channel width, short guard interval, high modulations, etc.)
  • data transfer rate requirements for each client (taking into account simultaneously actively transmitting traffic)
  • the nature of the traffic (type (TCP / UDP), packet size, VPN encryption (if the point works directly with the tunnel), etc.)

As a result, we can say that it is usually recommended to connect no more than 10-40 clients per wifi hotspot access, for high speeds - 3-7 clients. A more accurate choice depends on the conditions of a particular situation (according to the list above). The most accurate definition is experimentally in place (when simulating production).

When building a professional radio network (in which specialized devices act as both access points and clients) using polling protocols, performance is noticeably higher and its decrease from an increase in the number of clients is slower.

Alexey Zavorykin

It is possible to connect many devices to a Wi-Fi hotspot.

There is a limit on the number of devices and is expressed in the maximum number of IP addresses that the DHCP server issues.

How many devices can be connected to the router via WiFi at the same time depends on the device model, its parameters and characteristics. Connecting a large number of devices affects the speed and quality of the Internet.

The main reasons for the restriction

There are restrictions when connecting by cable. The number of connected devices depends on how many LAN connectors are placed on the router.
When connected via Wi-Fi, there is no physical limitation. The main reason for this is reduced wireless internet speed and freezes. Also, the limit depends on the capabilities of the access point and specific models: channel width, support for MIMO technology, modulation.
The number of connected gadgets is also affected by the nature of the traffic, packet sizes, encryption type, router settings, and transmission speed requirements.

Maximum number of devices over Wi-Fi

The largest number is specified in the start and end addresses. For example, for Asus, the start address is 192.168.1.0. and the end address is 192.1681.254.
Theoretically, you can connect 254 devices to Asus via Wi-Fi. For Link modems, this figure is 99. Each router is able to distribute the network to a huge number of phones, tablets, but technically it is not able to provide correct and stable operation for everyone.

In practice, dozens of devices can be connected. It is important to choose a router that will pull such a load. For example, in an office where you need to provide Wi-Fi to several laptops, you need to choose a model with improved performance, with powerful processor and power supply. Such a device will cost more than a home modem.

Modems for home use on average, they are designed for 5-6 phones, tablets, laptops. When purchasing, it is recommended to read the description, which indicates the maximum number of connected devices.

Conclusion

The largest number of connected devices is the number of IP addresses issued by the DHCP server. For various companies, the number exceeds 100. Not a single router will pull the theoretical maximum value of connected gadgets. The Wi-Fi transmission speed is equally divided among the connected devices, priority is given to the device that consumes volume resources. The largest value of the connected devices via Wi-Fi is determined empirically.

Good afternoon.

Did you know that the reason for the drop in speed in WiFi networks can be neighbors who connected to your router and occupy the entire channel with their jumps? Moreover, it would be okay if they only downloaded, but what if they start breaking the law using your Internet channel? Claims, first of all, will be to you!

That is why it is advisable to set a password on your Wi-Fi network and sometimes see who is connected to WiFi router(which devices, are they yours?). Let's take a closer look at how this is done The article provides 2 ways)…

Method number 1 - through the settings of the router

STEP 1 - entering the router settings (determining the IP address to enter the settings)

To find out who is connected to a Wi-Fi network, you need to enter the router settings. There is a special page for this, however, it opens at different routers - at different addresses. How can I find this address?

1) Stickers and stickers on the device…

The easiest way is to carefully look at the router itself (or documents for it). On the body of the device, there is usually a sticker on which the address for the settings is indicated, and a login with a password to enter.

On fig. 1 shows an example of such a sticker, to access the settings with "admin" rights, you need:

  • login address: http://192.168.1.1 ;
  • login (username): admin;
  • password: xxxxx (in most cases, by default, the password is either not set at all, or the same as the login).

Rice. 1. Sticker on the router with settings.

2) Command line…

If you have Internet on your computer (laptop), then you can find out the main gateway through which the network operates (and this is the IP address to enter the router settings page).

Sequencing:

  • first run the command line - a combination of buttons WIN + R, then you need to enter CMD and press ENTER.
  • at the command line, enter the command ipconfig / all and press ENTER;
  • a large list should appear, find your adapter in it (through which the Internet connection goes) and look at the address of the main gateway (you need to enter it in the address bar of your browser).

Rice. 2. Command line (Windows 8).

3) Spec. utility

There is a special utilities for searching and determining the IP address to enter the settings. One of these utilities is described in the second part of this article (but you can also use analogues so that there is enough of this “good” in the vastness of the network :)).

4) If the login failed ...

If you did not find the settings page, I recommend that you read the following articles:

Rice. 3.TP Link

Rostelecom

The menu in routers from Rostelecom, as a rule, is in Russian and, as a rule, there are no problems with the search. To view devices on the network, simply expand the " Device Information", DHCP tab. In addition to the MAC address, here you will see the internal IP address in this network, the name of the computer (device) connected to Wi-Fi, the network time (see Fig. 4).

Rice. 4. Router from Rostelecom.

A very popular model of routers, and often the menu is in English. First you need to open the Wireless section, then open the Status subsection (in principle, everything is logical).

Rice. 5. D-Link who joined

If you do not know the password for accessing the router settings (or you simply cannot enter them, or you cannot find it in the settings necessary information), I recommend using the second way to view connected devices to your Wi-Fi network ...

Method number 2 - through special. utility

This method has its advantages: no need to waste time searching for an IP address and entering the router settings, no need to install or configure anything, no need to know anything, everything happens quickly and in automatic mode(you just need to run one small special utility - Wireless Network Watcher).

A small utility that doesn't need to be installed that will help you quickly find out who is connected to your Wi-Fi router, their MAC addresses and IP addresses. Works in all new Windows versions: 7, 8, 10. Of the minuses - there is no support for the Russian language.

After running the utility, you will see a window like in Fig. 6. There will be several lines in front of you - pay attention to the column " Device information«:

  • your router - your router (its IP address is also shown, the address of the settings that we have been looking for so "long" in the first part of the article);
  • your computer - your computer (from the one from which you currently launched the utility).

Rice. 6. Wireless Network Watcher.

In general, an extremely convenient thing, especially if you have not yet figured out the intricacies of your router settings too well. True, it is worth noting the disadvantages of this method of determining devices connected to a Wi-Fi network:

  1. the utility shows only online devices connected to the network (i.e. if your neighbor is sleeping now and turned off the PC, then it will not find and show that it is connected to your network. The utility can be minimized to tray and it will blink for you, when someone new connects to the network);
  2. even if you see someone "outsiders" - you will not be able to ban him or change the network password (for this you need to enter the router settings and restrict access from there).

On this I conclude the article, I will be grateful for additions on the topic of the article. good luck!

How can I connect other home devices from which I need to access the Internet to the same cable?
There are several options for solving this problem. The most common option - it is also the cheapest - purchase and installation home router. Our new subscribers receive a free router upon connection!

Why do you need a router?
The main purpose of a router is to connect local networks. A home router is needed to connect your home local network and provider networks. Connecting to the Internet through any provider, you get only one cable to which you can connect one computer or one laptop, in fact one device. If you need to connect more than one device, you need another connection, and these are additional costs, both one-time and monthly. The router solves this problem. A standard home router, as a rule, has 4 standard RJ-45 connectors, into which you can easily connect a laptop, computer or game console.

What is the advantage WiFi router?

If your router is equipped with a WiFi access function, in addition to wired devices, you can connect several wireless devices. For example, a phone, tablet, communicator, laptop, and even a regular computer, if necessary. The routers that we give to our new customers are equipped with WiFi access.

How many computers can be connected to one router?
Any home router is not designed for a large load and, of course, has its limitations. These limits are not directly related to the number of devices connected to the router. Rather, the load that these devices create plays a role. If it's 4 powerful computers, continuously downloading hundreds of films and gigabytes of other content from the Internet, then, of course, under such conditions, working on the Internet from other devices will be difficult. However, if this is a standard home set of equipment, for example, a regular computer + a laptop + several phones / communicators / tablets that periodically request pages on the Internet, watch or download movies, download programs and music, then any home router will be quite enough to perform these tasks. .

What settings should be done for home devices to connect them to the router?

None. When connecting via cable, simply connect the connectors. If your home appliances have factory settings, they will be set up automatically within 3-10 seconds. When wireless connection you need to know 2 parameters. The first is the name of the network, the second is the password to connect to this network. WiFi network password protected to prevent unauthorized access. For example, if your home WiFi network is not password protected, then your neighbor can use the Internet access that you pay for, or, worse, can access your personal information that is located on your home computers.

If you receive a router as a gift from Intralan, the company's specialists will configure the router itself and home devices for free.

What else useful features does the router?

As a rule, home routers take on the function of protecting (firewalling) your home LAN from external influence from the Internet. That is, when using a router, your computer is hidden behind it. Any ill-wisher, whether it is malicious intent against you personally or a massive attack, will at least get additional difficulties by trying to disrupt your computer, or, most likely, will not be able to cause you any harm at all. The router that you will receive as a gift using our services is equipped with a firewall function.

Does the radio signal emitted by the router affect people and animals?

All equipment sold in retail stores in the territory Russian Federation, must have marks of certification and testing by the relevant regulatory authorities. If these marks are present, then the effect on the brain activity of people and animals does not exceed the norm, or is absent due to the low power of the device.

What is the range of a WiFi network?

Usually, the range of a home WiFi router is enough to ensure that the entire apartment has an acceptable signal level for free work on the Internet. This rule works if the total area of ​​the apartment does not exceed 120 square meters.
If you live in a private house, it is recommended to install a so-called repeater on each floor to increase the strength of the WiFi signal.
