Today, wireless routers (routers) allow users to do without many wires to access the Internet. All you need to do is set up your router and turn on Wi-Fi on your computer or phone. Wireless networking modes have been developed to improve throughput. With their help, you can increase or decrease the data transfer speed. The higher it is, the better the pages on websites will load and the faster media content will play. Therefore, many users ask which mode to choose for a wireless Wi-Fi router.
What is b/g Protection
Many users, when setting up routers from Asus, may find the “b/g Protection” item in the web interface. So the question arises, what kind of mode is this for a wireless network? This parameter is responsible for signal reception for devices that support 802b and 802g data transfer protocols. If the user sets these settings, he will receive high Internet speed, about 55 Mbit/s.
Which Wi-Fi mode is better Legacy or N-only
Basic connection steps
If wireless Internet is already configured, then you need to connect to the desired Wi-Fi network as follows:
- At the bottom right of the screen in the system tray you can see the wireless connection icon. If at this moment there is no wireless connection, then the usual image will be supplemented with an asterisk located in its upper left corner. This icon can also be seen when the network cable is connected.
- You need to click the icon. As a result, a list of available Wi-Fi networks will appear.
- Having selected the desired line from the list, you can see the “Connect” button. You need to click on it.
- A window will be prompted to enter your network access password. It must be entered manually and then confirmed.
Important! This procedure is the same for recent versions of Windows. On the tenth day after connecting, the system will ask whether to make this computer visible to other participants. If we are talking about a home network, then it is recommended to answer positively.
If the need arises to disconnect, this can be done in the same way. By clicking on the icon, you can access the list of networks. After selecting the one to which you connected, you can disconnect.
What wireless network modes are there?
Laptop does not connect to Wi-Fi: No connection to wireless network
Users often ask what Wi-Fi modes exist at the moment. There are two main ones: Legacy and N-Only. The first one is compatible with b/g/n protocols. In turn, N-Only can only work with the N communication standard.
Legacy
The question, N-Only or Legacy Wi-Fi - what is it, is relevant for owners of wireless routers. Legacy mode allows devices that support the 802 b/g/n communication standard to connect to the router. The maximum data transfer speed will be no more than 54 Mbit/s.
N-Only
It makes sense to set this mode if the devices support the 802n communication standard. In this case, users can get the maximum packet transmission speed of more than 100 Mbit/s. It is important to know that devices that support 802 b/g protocols cannot be connected to the router.
Differences Wi-Fi b/g/n
When setting up a router, the following questions often arise: Wi-Fi b/g/n – what does this mean and how can they differ? First, you need to consider each of the modes in detail and understand what their difference is.
Wireless Wi-Fi network b/g/n differences:
- “b”: this type of connection has a low Internet speed of up to 11 Mbit/s.
- “g”: this type of mode has a speed of at least 54 Mbit/s.
- "n": provides data transfer speeds of more than 150 Mbps.
Comparison of Wi-Fi modes b/g/n
An example of using b/g/n Wi-Fi modes: the owner of a Lenovo A2010 smartphone has set the settings for an 802n access point in the router. According to the technical specifications, the phone does not support the “n” standard protocol. A communication error appears when connecting to the network. This is due to the fact that the device can only work with b/g modes.
Important! Errors when connecting to an access point on laptops are often also due to the fact that the device cannot support newer communication standards. You must carefully read the operating instructions.
Also, when setting up your router settings, you should set the wireless network operating mode to automatic. This method will help avoid connection failures.
Other
Recently, a new type of Wi-Fi mode has been developed - 802ac. It replaced the current N standard and is the fifth generation of networks. With its help, data transfer increases several times and amounts to more than 1 Gbit/s. Most devices operate at 2.4 GHz and 5 GHz, while the 802ac has a 6 GHz frequency.
It is important to note that routers operating at a frequency of 2.4 GHz have a greater signal range of up to 30 meters. But due to the fact that a significant amount of “household waves” (microwave ovens and radio electronics) propagate in homes, the signal quality noticeably deteriorates. Thus, users experience connection dropouts and low Internet access speeds.
If we talk about the frequencies 5 GHz and 6 GHz, then they have a short signal range, but at the same time they can boast that their channel width exceeds 160 MHz. Thanks to this, the speed of your Internet connection increases several times, up to 1 Gbit/s. But at the moment there are not many devices on the market that can support the 802ac wireless network operating mode.
Important! The larger the channel width, the higher the data transfer speed. In this case, loading pages and playing media content on sites will be several times faster than when using Wi-Fi b/g/n operating modes.

Access Point Isolation
If the MAXg Wireless Router will be used in a public place and you do not want any wireless clients to be able to share files or printers, select the Access point isolation check box. In this case, all wireless clients will only be able to access the Internet. An example of a situation where you might need to use this feature is when you are in a crowded public place, such as a cafe or hotel. By default this feature is disabled.
Which Wi-Fi router mode to choose
Wireless network security key - how to find out
As a rule, when automatically configuring a router, the combined operating mode of the wireless network is set to “Auto 802 b/g/n”. Thanks to these settings, device compatibility is ensured, and, as a result, errors or failures when connecting to an access point are eliminated. Many router owners want to understand which is better, Wi-Fi mode 11b/g/n or 11b/g.
Before changing the mode or channel, you need to use the network card in the router’s web interface and see which channel has the most connected devices, then select the least loaded one. If the network card is not provided for in the router settings, then you should use special software. The most preferred and functional option is the “Wi-Fi Home” utility.
Which is better, 11b/g/n or 11b/g mode
The 11b/g mode can only operate at frequencies not exceeding 2.4 GHz. In turn, 11b/g/n has maximum compatibility with devices and can operate at frequencies up to 5 GHz. Thus, the main difference lies in the speed of operation: the higher the frequency, the faster the user can load content on the site and get minimal signal delay.
How to change the wireless network mode (universal instructions for all types of routers):
- On the back panel of the router, find a sticker where the username and password for the web interface will be written.
- Then open a web browser and enter the router IP in the address bar. For most models it is as follows: 192.168.0.1 or 192.168.1.1. For Huawei routers, the address for setting up the web configuration is 192.168.8.1.
- In the main menu, open the sequence of items: “Wireless network” (or Wi-Fi), “Mode” (standard or settings) and “Radio frequency range”. Set the parameter to “11b/g/n” (mixed) or “11b/g”. All that remains is to reboot the router.

Which is better: Legacy or N-Only wireless network mode
Many router owners ask which wireless network mode, Legacy or N-only, is better. To get the maximum Internet connection speed, it is best to set the N-only mode in the settings. In order to be compatible with all types of devices, the Legacy standard is most suitable. When using the first option, the connection will be made at speeds of up to 54 Mbit/s, and with the second method - over 100 Mbit/s.
Possible problems
Even if the Wi-Fi adapter is configured correctly, the following connection problems may occur:
- there is no wireless networks icon in the tray;
- the Wi-Fi icon is crossed out;
- the icon displays a snowflake;
- The wireless connection is established, but the Internet does not work.
No Wi-Fi icon in tray
This problem on the laptop does not always mean that the network is not working. Sometimes its disappearance is due to the personalization of the OS. In Windows 10, you can check the icon display settings like this:
- Open Settings via the Start menu. Go to the "Personalization" section.
- In the notification area, click on “Icons displayed in the taskbar.” Make sure the checkbox next to wireless networks is checked.
- Go to the “Turn on and off system icons” section and make sure that the toggle switch next to the network is set to the “On” position.
If after this the Wi-Fi icon does not turn on, restart Explorer:
- Open “Task Manager” using the Ctrl+Shift+Esc button combination.
- Find “Explorer” in the list of active processes.
- Right-click on it and select “Restart”.
Wireless network icon crossed out
The problem occurs when the Wi-Fi adapter is deactivated. To be able to connect the laptop, it needs to be started.
Use a key combination or a special Wi-Fi enable button. Make sure you don't accidentally activate Airplane mode.
You can try to enable the adapter through “Network Connections” by selecting the appropriate item in the context menu.
The Wi-Fi icon shows a snowflake
This is not a bug or problem. The system simply notifies the user that there are available wireless networks to connect to.
To connect to your home router, click on this icon and select the desired network. Then you will need to enter a password and click on the “Connect” button.
If you are unable to connect to the network, restart the router.
What to set in the router settings to get the highest speed
The WlanSvc wireless network auto-configuration service is not running - solution
To get maximum speed, you should specify the following parameters in your router settings:
- Use only one 802n wireless network mode.
- Set the encryption type to WPA2 AES.
- TP-LINK routers allow you to disable the speed limiting option.
- Set the bandwidth of the channel to 20 MHz.
- You should install new driver updates for your Wi-Fi controller.
- Place the router away from the TV, microwave oven and cordless telephone.
When choosing a wireless network operating mode, you should take into account the technical characteristics of the router and the devices connected to it. To increase data transfer speed, it is better to set mixed settings. To improve the quality of signal reception, it is necessary to select channels with the least load.
802.11n standard
Double wan on an asus router.
what is it and how to set it up? Despite the fact that this modification has been on the market for a long time and has impressive parameters, manufacturers are still working on improving it. Due to the fact that it is incompatible with previous standards, its popularity is low.
- Information transfer speed is theoretically up to 480 Mbit/s, but in practice it turns out to be half that;
- Frequency range - 2.4 or 5 GHz;
- The range is up to 100 meters.
Since this standard is still evolving, it has its own characteristics: it may conflict with equipment that supports 802.11n only because the device manufacturers are different.
RAM in the router
Let's start with RAM. First of all, you need to understand that a router is essentially a small computer. Only it does not perform such complex computing functions as a desktop PC, laptop or even a smartphone, but simpler ones. Because of this, the characteristics of all components in it are weaker. But like any computer, the router has a processor, RAM and a flash drive. Moreover, they are all of small capacity.
The router's job is to process information packets and transmit them to a particular device via a wireless signal or cable.
- For example, at the moment when you turned on your computer, connected to the router and accessed the Internet through it, you requested some information from a remote server on the global network, which the router transmitted to you through its RAM.
- Another case is that you connected a video surveillance camera to the router and, using a program on your smartphone, accessed it remotely from the Internet to look at the image from it online. Again, this happens using the router's RAM.
- Another one is that you connected a flash card or an external hard drive to your router and distribute files from it over the local network. All of them, before getting to your device (TV, phone, computer), pass through the router’s memory.
And so on - you can come up with a huge number of action scenarios. The main thing to understand is that the router’s RAM is involved in all processes of processing information that passes through it.
More simultaneously connected devices, more simultaneously performed tasks of varying complexity - online games, video, video calls, surveillance, and so on. The minimum amount of RAM for comfortable use of the router is from 64 MB.
Opportunities for IoT
The IEEE 802.11ah standard has three features designed for Wi-Fi 6. The first is dual-carrier modulation. Each symbol is mapped onto two subcarriers widely spaced in frequency. The overall effect is to increase receiver sensitivity by several decibels, which may be useful in outdoor systems. The second function is target wait time (TWT), a form of scheduling in which the user equipment tells the access point its available communications window. At the same time, the struggle for the right to transmit is weakened and, more importantly, the power consumption of remote devices is reduced due to the refusal to constantly listen to the channel in anticipation of the possibility of transmission (Fig. 7).
Rice. 7. Using TWT allows you to optimize power consumption and reduce the load on the network
Because these devices are capable of operating in dense environments, it is necessary to allocate a basic service set (BSS) that is transmitted in the same range. The solution is called “spatial reuse.”
In order to distinguish frames from specific BSSs, color marking (BSS coloring) is used. Each access point is assigned a different color. Subscriber stations may ignore signals with a color code different from the required one.

What does authentication error mean on Android?
Those who are faced with a similar situation most often take the following steps:
- Connect to WiFi network
- They enter the password and see the message “Authentication” for a long time - the smartphone is trying to connect to the router
- After which the message “Authentication Error”, “Authentication Error” or “Authentification Error” in English appears - that is, it was not possible to connect
- And then the connection status changes to “WPA/WPA2 Saved”. This means that the phone has saved the entered value in the memory of its Android and will now always try to use this authorization key for this WiFi
