present, wireless routers in the indoor launch power generally does not exceed 20dBm. The higher the transmitting power of the wireless router, the higher the signal strength, but more than the specified range will cause large electromagnetic radiation and interference. Antenna gain: The greater the gain, the stronger the signal strength, at present, most of our routers antenna gain 3dBi. Working Band: The current WiFi has 2.4G and 5G two bands, in

normally runs in maximum protection mode, automatically switches to maximum performance mode when the primary node is disconnected from the standby node or is not connected properlyThe operation of the U master node can continue. In the case of bad network, there is a large performance impact.N Maximize performance: This pattern should be said to be inherited from the 8i standby server mode, asynchronous transfer,U No data synchronization check, may lose data, but can obtain the maximum perform

Dual-frequency WiFi refers to a device that supports 2.4ghz/5ghz dual-band wireless signals and supports a 802.11a/b/g/n full wireless network, which belongs to the fifth generation Wi-Fi transmission technology (5G Wi-Fi), Typically, the routers or some WiFi devices that we are exposed to on a daily basis support 2.4Ghz WiFi, which is likely to be a new generation of wireless technology with high-end routers or some future tablets, boxes, and smartph

Many business users need to use a USB disk in the Multimedia conference Room demo, and multimedia conference room is public, all kinds of u disk are contacted with it, easy to be infected with the virus, eventually all plug in the conference room computer USB drive are infected with the virus. Some users use U disk to start the computer directly, with Diskgenius and VMware to the U disk partition, and then install the Veket system, so that neither infected virus, but also convenient file managem

Specific steps (take the iphone as an example below) 1. In the mobile phone we click "Settings" > "General" > "Software Update", we see if it is possible to update the latest mobile phone system (this can be upgraded or not upgraded). 2. If you want to upgrade to upgrade it, do not upgrade we click on the iphone "Settings" > "ICloud" > "Storage and Backup" Here you will see the data we backed up, there is a "last backup" message, and the last backup date later. 3. Now we go to the iphone

Internet access through the router, if the use of the environment, the ios/android system wireless terminals can not search the router signal, you may follow the following methods to troubleshoot: [IOS] Do not search for wireless signal When the wireless terminal is unable to search for a signal, verify that the wireless terminal's wireless switch is turned on. As shown in the following illustration: [Android] Do not search for wireless signal When a wireless terminal cannot search for a s

Objective At the time of this writing, TLS1.3 RFC has been released to version 28. Previously wrote a bit of cryptography and TLS related articles, in order to further understand the TLS1.3 protocol, this time will try to use the go language to implement it. There are already some sites on the network that support Tls1.3,chrome browsers through settings that support TLS1.3 (draft23), which can be used to verify whether the protocols we implement are standard. The complete implementation TLS1.3 a

802.11a The High-Speed WLAN protocol uses the 5G Hz band. The maximum speed is 54 Mbps. The actual usage rate is about 22-26 Mbps. Being incompatible with 802.11b is the biggest drawback. 802.11b Currently, the most popular WLAN protocol uses the 2.4G Hz band. The maximum speed is 11 Mbps. The actual usage rate is variable based on the distance and signal strength (1-2 Mbps within 150, 11 Mbps within 50 ). The low rate of 802.11b makes the cost of
