allocate the IP addresses of computers in the network, but in actual use DHCP can cause network instability, such as the lease to get IP again but found that other computers in the network are already using the IP address, Or the DHCP information is frequently negotiated between the computer and the wireless router.
In fact, these DHCP packets can not be completely, for the average home users, the network is not a large number of computers, we can manually set the IP address and other network
here to "Cisco Linksys BEFW11S4-CN Wireless Router" as an example to introduce its specific settings.
As the world's leading network equipment and solutions provider, Cisco Linksys has focused on Soho and home markets, BEFW11S4-CN has a 10/100m RJ-45 port for connecting to broadband modems, four 10/100m RJ-45 Exchange port and a shared uplink port.
After installing the driver, enter the default account a

For example, the SSID of a Linksys device is usually "Linksys". If a network does not specify an SSID for it or only uses the default SSID, then any wireless client can access the network. This has undoubtedly opened the door for hackers to invade the networ

The D-Link DSP-W215 smart outlet is a socket that uses a wireless control power switch. You cannot buy firmware from Amazon or best practices, but you can download the firmware from the D-Link website ).
DSP-W215 has a stack overflow vulnerability that can control the entire socket device, but also control the switch of other electrical equipment on the socket device.0x01 analysis

Here, we use an example in our daily life to demonstrate the implementation of the adapter mode. The specific scenario is: in our daily life, the electrical plug we bought has two holes, however, the outlet we bought only has three holes. At this time, we hope that the electrical plug can be converted into three holes, so that we ca

You may have noticed that there is an outlet (output port) on this arrow. outlet can be seen as a pointer from C to V, which is defined in C. Outlet provides us with great convenience, which enables us to easily and accurately execute orders to V within C. C can have more than one outlet, which makes it

bank's integrated office building as an example, we will describe the Application of Integrated Wiring in financial buildings.Project OverviewA bank is a large commercial bank. The total construction area of the integrated office building is 22.6 thousand square meters. The ground floor is 16 floors, and the ground floor is 2 floors. The ground floor from 1 to 4 is a podium, and the ground floor above 5 is a standard floor. Taking layer 6 as an example, the horizontal trough is derived from the
connection between a terminal and an information outlet. It consists of an extended soft line that is compatible with a soft line, connector, and connection. The work zone components involved in the Three Gorges Construction Management Center project are as follows:Information outlet: there are two types. One is the copper information outlet meeting the general

In the implementation of this example, we actually implement the-soundEffect getter method, so there is no problem with the getter call of the vertex method on the right of the equal sign ). To avoid misunderstanding, we recommend that you rewrite the getter call of self. soundEffect to [self soundEffect]. Then let's take a look at the property ~ in. h ~ There
There are three main channels for fund sales: Direct Selling centers of fund companies, bank consignment outlets, and securities companies' consignment outlets. Now the postal savings outlets have become the fourth channel for fund sales. A few other professional fund sales companies can sell funds.
What are the differences between fund subscriptions through different channels?
Direct selling center of fund companies: the advantage is that you can use online transactions to handle account ope

◆ The PDS cabling system meets the current and long-term voice and data communication requirements of users;◆ The Layout System of the PDS complies with international and domestic standards;◆ A star topology is used for the layout of the PDS;◆ The design of the tps' cabling system must support requirements for telephone, fax, and computer networks;◆ The speed of
time, it also has the advantages of softness, bending resistance, vibration resistance, anti-radiation, low price, and convenient construction, which can replace the traditional Z optical fiber and copper cable, and is very suitable for local networks with many connection points.
Using Plastic Optical Fiber to construct a large-scale local area network requires two products: passive wiring and connecting products and active plastic optical fiber network equipment.
