LinkSys Wireless routers on the market as an example to see the wireless router security settings.
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 operating s
We must be familiar with computer operating system vulnerabilities. In fact, vrouters and computers also have operating systems and vulnerabilities, this article describes in detail some problems related to the Linksys vro security vulnerability and how to prevent it. After research, the Linksys router has a security vulnerability. Attackers can remotely hijack the Link
This article describes how to configure a linksys wireless router, I hope this article will give you a better understanding of router settings.1. Buy a wireless router to better experience wireless Internet access. In addition to running the wizard on the CD, set a linksys wireless router, another method is to enter the router configuration page to configure the router, which is also the most common method.
reduced by the ability to transmit voice, video, and data over a converged IP network, the Unified Communication solution can save considerable costs for enterprises.Misunderstanding 3:In today's IP communication field, there is no super powerful application.Actual Situation: enterprises use the Internet for different reasons. similar to this, enterprises use Unified Communication for a variety of reasons. Currently, many Unified Communication applications can reduce costs, increase productivit
communication needs and telephone communication needs. However, because there are multiple independent parallel physical networks, there is no connection between them, the construction and maintenance costs are relatively high, and the O M is difficult.
According to the situation in China, apart from the construction of internal telephone systems by itself in specific industries such as power supply and public security, some of the general enterprises and institutions deploy their own data net
Communication solution runs through a smart phone. The supplier provides a special client software package for each mobile phone, thus limiting the user's choice of the device. If a user is used to a device that the mobile Unified Communication vendor does not support, there will be a huge controversy between the supplier and the user.
Mobile Unified Communication vendor
Mobile Unified Communication vendors can be divided into three categories: Unified Communication vendor, ip
The concept of softswitch was born
The concept of softswitch originated first in the United States. At that time, in the enterprise network environment, users used Ethernet-based phones to implement the PBX function through a set of Call Control Software Based on PC servers ). For such a set of equipment, the system does not need to separately lay the network, but can achieve unified management and maintenance only through sharing with the LAN, the ov
suitable for a wide range of applications, such as home, corridor, desktop, and IP supermarkets. However, IAD is a terminal device, which is inconvenient for management and maintenance.
Through the Access Gateway AG or the FXO port of the integrated access device IAD, the gateway can communicate with the PBX through the AT0 loop relay. The traditional old-fashioned PBX mostly accesses the softswitch networ

With the rapid development of wireless technology, wireless routing functions are more abundant. Here we mainly analyze the specific characteristics of Cisco WRT160N wireless routing function. The new Cisco LINKSYS WRT160N Ultra RangePlus Wireless-N Wireless Broadband Router is designed in a new fashion and provides a variety of featured Wireless routing features such as Linksys Easylink Advisor (LELA, LELA
for cost effectiveness.

Step 1: we must first connect the power of each hardware device. Second, insert the telephone LINE into the LINE port of the modem, and use an Ethernet cable (non-crossover) to connect the Ethernet port of the modem to the WAN port of the router. Then, use an ethernet cable (non-crossover) to connect the LAN port of the router (either of the interfaces provided) to the UpLink port of the hub or switch. Of course, if you have few machines, you can also
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

Long-distance Ethernet Technology
LRE technology uses orthogonal amplitude modulation (QAM ). The QAM amplitude modulation uses the signal amplitude and phase to define each symbol. LRE adopts the most advanced QAM technology, has a variety of QAM am QAM-256, QAM-128, QAM-64, QAM-32, QAM-16, QAM-8 and QAM-4 ). The system administrator can choose to adopt different amplitude adjustm
