Is Security important or speed important? Do you have a dilemma? Does encrypted wireless networks affect the speed of wireless Internet access? What are the methods for encrypting wireless networks? We will provide you with all the information you need.
1. Do I have to encrypt wireless network communication to improve
wireless network adapter must first compare whether the SSID number is configured to be connected. If yes, the connection is performed. If not, the SSID broadcast packet is discarded.
Readers who have experience in cable network maintenance must have heard of sniffer. With sniffer, we can monitor our network card, so that the network card will record all the pac
ColorSoft (formerly Anti ARP Sniffer ). The biggest feature of the software is that the system kernel layer intercepts false ARP packets and proactively notifies the gateway of the correct MAC address of the Local Machine. This ensures that the computer where the software is installed can access the Internet normally, it also intercepts external ARP attacks on the local machine.
If an internal ARP attack is detected, the attacker can directly process
Nmap Concept
NMap, also known as Network Mapper, is the first web scan and sniffer toolkit under Linux.
Nmap is a network-side scanning software used to scan Internet computers open Network connections. Determine which services are running on which connections, and infer which operating system the computer is running (this is also known as fingerprinting). It is one of the required software for network administrators and is used to evaluate network sy

operations of communication with the Internet are pre-configured by the router manager. The only special feature of wireless Internet access is that information is transmitted by radio waves without passing through the network cable between the computer and the route. However, for the entire network, there is no difference between the star topology structure formed between the wireless route and the client
With the development of the routing industry, wireless technology has become its development direction. Here we mainly explain the differences and connections between wireless routers, wireless APs and wireless bridges, I hope to have a deeper understanding of wireless devic
, the wireless network security setting function can not be helpless.
Wireless Security Response measures:
What measures should be taken to ensure the safety of wireless networks for ordinary wireless network users? In order to make wireless Internet as safe as possible,
Wireless AP:
AP for access point abbreviation, generally translated as "Wireless Access Node", which is mainly to provide wireless workstations to the wired LAN and wireless workstations from the wired LAN access to the wireless workstation in the access points covered by
the internet!
Using Wireless Hotspot Internet access is actually a way to access the Internet through a LAN. We do not need to dial or establish remote peer network, and the specific operations of communication with the Internet are pre-configured by the router manager. The only special feature of wireless Internet access is that information is transmitted by radio waves without passing through the network
Encrypted wireless networks are the most basic security protection measures for wireless Internet access. What encryption methods are there? Next, let's take a look at the various wireless encryption methods in detail, hoping to be useful to everyone. Let's take a look.
