AP isolation is a computer mode. AP isolation refers to the fact that each connected computer cannot access each other and play an isolation role to ensure the security of different users.
More common in wireless communications, common in router settings. AP isolation is very similar to the VLAN of a wired network (virtual local area network), completely isolating all wireless client devices, so that the client can only access the fixed network accessed by the AP.
Scope of application
This 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.
Open ap isolation can prevent flooding1, login router settings
2, click on application management
3, click AP isolation
4. Select Open and click Save!
5. At this point, the AP isolation setting is completed! In fact, AP isolation settings are very simple, many of the key friends do not know its function! The following is also simple: Many of the friends have the same owner WIFI used when visiting, which makes the customers connected to the same network directly have data security sharing problems. If AP isolation is enabled, the devices connected to the WIFI network cannot be connected. Mutual access, isolation from each other, play a very good security role!
Enable AP isolation to effectively prevent LAN attacksYes, 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.
SMD transformer Description: small size, high working frequency, high adhesion performance, small distribution inductance;It is mainly used for module power supply, laptop, mobile phone and ultra-thin electric appliance.
The transformer consists of an iron core (or magnetic core) and a coil. The coil has two or more windings, of which the winding connected to the power supply is called the primary winding and the rest is called the secondary winding.It can change ac voltage, current and impedance.The simplest core transformer consists of an iron core made of a soft magnetic material and two coils with different turns on the core.
