AP isolation, AP Isolation, refers to the ability to enable each connected computer to access each other and provide isolation to protect data security between different users. It is suitable for large-scale wireless network construction in public places such as conference rooms, hotels, airports, etc., and is not suitable for ordinary home users. This document describes how to set up AP isolation for cloud routers.
Why do I need to use AP isolation?If you need to prevent wireless terminals from communicating with each other, you can turn on AP isolation. For example, your coffee shop provides wireless WiFi for customers, but in order to protect the security of the customer's wireless terminal, wireless terminals are prohibited from accessing each other (reducing the risk of being attacked by a local area network), and AP isolation can be used.
The effect of AP isolation is as follows:
The English term for AP isolation is AP Isolation. More common in wireless communications, common in router settings. The AP isolation of a wireless router can be similarly seen as a VLAN in a wired switch.
The VLAN is simply: only LAN devices in the same VLAN can access each other. For example, in the wired switch, device A and device B are divided into VLAN 10. The other devices are in the default VLAN 1. Then device A can communicate with device B only, and cannot communicate with devices between different VLANs. Scanning does not scan. Ping can also ping through; the rest of the devices in VLAN1 can access each other. Similarly, they cannot access device A and device B.
In the same way, back to the wireless routing settings, enabling AP isolation means assigning a separate "VLAN" identifier to all devices. Each device is in a different "VLAN", so you can only access the gateway and the external network. The devices cannot access each other.
The wireless router enables AP isolation, which is very suitable for wireless network construction in public places such as large conference rooms, airports, hotels, etc., so that each connected wireless client remains isolated and provides more secure access to each other. Sex, shortcomings are also obvious, that is, all wireless devices can not communicate with the LAN, and many applications can not be used.
Ap isolation scopeThis measure is very suitable for the wireless network construction of large conference rooms, hotels, airports and other public places, so that the wireless clients connected to each other are isolated from each other, providing more secure access to each other. This measure does not have much practical significance for home users, but enterprise users can use this approach to enhance the security of wireless networks in special occasions. For example, public events such as meetings attended by customers or outsiders. The method is used for the erection of hot spots such as hotels and airports, so that the connected wireless clients remain isolated and provide secure Internet access.
Ap isolation Zhao Li should be open, why? Because opening AP isolation can effectively prevent LAN attacks. The reasons are as follows:
Yes, the AP isolation of a wireless router can be similarly seen as a VLAN in a wired switch.
The VLAN is simply: only LAN devices in the same VLAN can access each other.
For example, in the wired switch, device A and device B are divided into VLAN 10. The other devices are in the default VLAN 1. Then device A can communicate with device B only, and cannot communicate with devices between different VLANs. Scanning does not scan. Ping can also ping through; the rest of the devices in VLAN1 can access each other. Similarly, they cannot access device A and device B.
AP isolation in a wireless router is to assign a separate "VLAN" identifier to all devices. Each device is in a different "VLAN", so you can only access the gateway and the external network. You can't do anything else, so say As a result, ARP attacks cannot be performed.
The advantage is that the security is improved, and the disadvantages are obvious. That is, all wireless devices cannot communicate with the local area network, and many applications cannot use them.
1. Log in to the router management interface, click Device Management, and enter the management settings page, as shown below:
2. Find the AP isolation and click to enter.
3. Click on Open and click Save as follows:
After this setting, AP isolation is enabled.
Note: AP isolation is only for a single router. If you have multiple routers cascading, you want to achieve isolation of all wireless terminals, you need to use VLAN-switched switches (usually used in large and medium-sized LAN).
A slip ring is an electromechanical device that allows electricity and data to pass through a rotating assembly. A mercury slip ring uses liquid mercury as the electrically conductive element inside the rotating assembly, as opposed to traditional carbon brushes. Mercury is a better conductor of electricity than carbon, and it also has a very low contact resistance. This makes it an ideal choice for applications that require high-speed data transmission or where reliability is critical. Mercury slip rings are used in a variety of industries, including medical technology, aerospace, and defense.
Why do we choose a mercury slip ring?
A slip ring is an electromechanical device that allows electrical current to pass between rotating objects. Slip rings are often used in applications where a cable or connector would otherwise twist and tangle as the object rotates. There are many different types of slip rings, but one of the most common is the mercury slip ring. Mercury slip rings offer several advantages over other types of slip rings, including high reliability, low maintenance, and long life. Here are three reasons why we choose a mercury slip ring:
1. Reliability: Mercury is an extremely reliable material, and mercury slip rings are among the most reliable types of slip rings available. Mercury has a very low failure rate, and it is not affected by changes in temperature or humidity. This makes mercury slip rings ideal for critical applications where reliability is essential.
2. Low Maintenance: Mercury slip rings require very little maintenance. Because mercury is a very inert substance, it does not corrode or generate any corrosive gases that would affect its reliability. Mercury slip rings do not require any lubrication, and they can operate in a wide range of temperatures and environments.
3. Economical Mercury slip rings have a lifetime cost advantage over other types of slip rings as well. Generally speaking, mercury slip rings are approximately 25% more expensive per kilowatt than other types of slip rings. However, because they require less maintenance and have a greater degree of reliability than other types of slip rings, they will save you money over the lifetime of your equipment.
