If there are two or more network access points in an area, how can a device (for example, a notebook) identify signals from these access points?
First, each WiFi device has its own unique physical address that has been set up at the factory and can be reconfigured. For example, a Linksys WiFi 5 Hertz Wireless access point Physical address may be 00:25:9c:57:0c:0f, this address is included in each frame sent by the router, so other wireless devices ca
). However, Viehbock says, most users can't tolerate such a long wait time. A typical identification takes only 1-3 seconds. A clever hacker will also take some steps to reduce this time.
Suppose an identification process takes 1.5 seconds. With a maximum of 11,000 identification, the hacker may gain access for approximately 4.5 hours or less (perhaps nearly 2 hours). In the coffee shop or on many other occasions, two hours will certainly not attract the attention of others. As its name implies
1. What is DD-WRT?
For the sake of respect, it is necessary to give a brief introduction to the predecessor of the DD-WRT, The DD-WRT is a "third-party" firmware, used for Linksys WRT54G/GS/GL or other 802.11g wireless routers based on the Broadcom reference design. Because these routers use the Linux operating system, the manufacturer has released the source code of these firmware based on the GPL terms.
The first version of DD-WRT was developed base

Hardware firewils don't have to be expensive. For instance, Netgear and Linksys models sport sufficient features for a reasonable cost.
Hardware firewalls are not expensive. For example, the Netgear and Linksys modules are worth the money.Endurer Note: 1. NetGea
principle:Most wireless routers display the list of connected clients, along with their associated host names, in the DHCP assignment information in the management interface. The list of display host names is derived from the DHCP request packet, which is sent by the client to the router (because the router also acts as a DHCP server). Then, since the request for an IP address does not require authentication, any user who has access to the local network can execute, through its host name, you c
Compared to wired networks, wireless networks have freed us from the shackles of cable, bring us great convenience, at the same time we must also consider that, if not set, within a certain coverage, wireless network is open to anyone, on the one hand, may be easy for strangers to enter their own network, using our bandwidth, On the one hand, it may cause information leakage. Let's take a look at the security configuration in the wireless router today.
Let's start with the wireless router. Ther
security settings of the wireless router with a lot of LinkSys Wireless routers on the market as an example.
The LinkSys Wireless Router uses a smart Wizard to set up a wireless router to help you. Therefore, many friends may not know how many IP addresses they have configured, but even the IP addresses of the wireless router. Here is a simple method to obtain this information. In most cases, the Windows o
With the development of China's routing industry, Wireless routers are also widely used. Here we mainly explain a new Wireless-N Wireless router launched by Cisco, cisco Wireless Router WRT320NWRT320N is the latest Wireless-N Wireless router launched by Linksys. This product is consistent with the excellent quality and exquisite workmanship of Linksys, it began to focus on the appearance design, WRT320N usi
At present, Small Enterprise routers have a high market demand, and their performance and characteristics are also suitable for small and medium-sized enterprises. We believe that with the development of routing technology, Small Enterprise routers will also be improved. For small enterprise networks with dozens or dozens of clients, Household broadband routers cannot meet their needs due to limited performance.
However, the use of high-configuration enterprise-level broadband routers will make
Firewall Builder (fwbuilder) is a graphical application that helps you configure IP packet filtering. It can compile filtering policies of various specifications you define, including iptables and Cisco and Linksys routers in various languages. This method separates the actual policies you define from the specific implementation of these policies, so that you do not have to redefine the firewall policies of the platform when changing the operating har
disk is usually formatted into multiple partitions. Similarly, FLASH is formatted into multiple partitions. Generally, FLASH is divided into four blocks, which have the following functions.Bootloader: initializes the hardware environment, updates the firmware, recognizes the file format of the operating system, and loads the kernel into the memory for execution. "CFE" is the abbreviation of "Common Firmware Environment" (Unified Firmware Environment). It is a Bootloader software developed by Br
Wireless route connection setting is a key step for us to connect to the Internet over wireless networks. Whether or not we can connect to the Internet over wireless networks is a matter of fact. Therefore, we will focus on this part of knowledge. Check the hardware and system configurations. The reasonable coordination between the wireless network card and the router connection settings is worth discussing. Set the time period in "Vista system" and "Xp, then some functions of the start time per
network address translation (nat) Protocol to support network connection sharing among Wireless LAN users. This is a useful feature in the soho environment. They may also have basic firewalls or information packet filters to prevent port scanning software and other attacks against broadband connections. Finally, most wireless routers include an Ethernet converter with four ports to connect several wired PCs. This is very convenient for managing routers or connecting a printer to a LAN.

OpenWrt package management provides a completely writable file system, select and configure from the application vendor and allow you to customize the device to adapt to any application by using the package. For developers, the OpenWrt framework is used to build applications without creating a complete firmware. for use

Some may have started the development of Windows Phone 7, but there is a very real problem that Windows Phone 7 is still difficult to buy, or the price is relatively high. Even if you have purchased a mobile phone, you must unlock the mobile phone before it can be used.ProgramDebugging. Therefore, most Windows Phone 7 developers in China are still at the simulator debugging stage. To help developers, wpmind provides an unlocked Windows Phone 7 mobile phone for program debugging.
