transport layer generally goes through the transmission connection establishment phase, the data transmission phase, and the transmission connection release phase to complete a complete service process. in the data transmission stage, there are two types of data transmission: general data transmission and accelerated data transmission. The transport layer service is divided into five types to meet the different requirements of transmission quality, transmission speed, and transmission cost.

1. Create an experiment environment
Before we begin, our first step was to build an experimental environment where you could not use others' networks to crack your work. This would violate the law and be an immoral act. To build a wireless network platform in an experimental environment, Wireless AP is indispensable. In addition, three laptops with wireless NICs can also be used on desktops with wireless NICs) A simple network can meet the requirements. Figure 4 shows the n

You only need to log on with the first started process and then modify the resolution.Firewall-it is recommended that you ignore Internet connections to learn how to use your firewall or you already have a hardware router/firewall (such as D-Link and Netgear
Ubuntu ADSL dial-up Internet access
I have been connected to the Internet through Wireless wifi connected to ADSL at home. Recently, I have destroyed the NetGear wireless router, so I have to use wired cable for the time being.
In Ubuntu Linux, you can also directly use ADSL dial-up for Internet access.1. Connect the device

Small tip:
I have introduced to you how to use the wireless router system vulnerabilities to modify the Netgear product login management password, interested readers can search IT168 Family network channel related articles.
The first step: conn
signals sent out to form a WiFi share of the Internet coverage. According to the different power, the network coverage degree is also different, the general wireless AP's maximum coverage distance can reach 400 meters.
The extended AP is what we often call a wireless router. Wireless routers, as the name implies is a wireless coverage of the router, it is mainly used for users to the Internet and wireless coverage. Through the routing function, we can realize the sharing of Internet connection
the internet and browse bad content of the site, generally through the wireless router access control function to set. For example, through the Domain name filter (URL filtering) function can control the Internet date, time, set to prohibit access to the site keyword. In the purchase of wireless router products, it is recommended to try these features hands-on, because in some low-end products only provide a simple domain name filtering function. 5. Price Price is to buy any product need to
simple, because we need to enter the router settings related parameters, such as filling in the Internet account and password and open no line by the function, etc. Therefore, you must use a network cable to connect the computer before you can enter the router setup interface.
The above line is connected, we turn on the computer, then you can enter the router set up, how to enter the router's internal settings, you can see the router Shell tag has a clear label. Generally speaking, the default

Although the WiFi consortium announces that it can theoretically achieve the throughput of 1.3 Gbps, it is twice times more than 802.11n. means that the network can simultaneously support the transmission of high-definition quality video streams to multiple devices. In fact, you can't see 802.11AC theoretically 1.3 Gbps throughput unless you're testing a lab rather than your office, and to achieve the highest speed you need to suppo

If you do not know if you are using IPV6, most of the cases indicate that you are not using it. This service is a software firewall for IPV6. Most users should close it. Read here to learn how to turn off Fedora's IPv6 support.

. The first step was to get to the raspberry Pie IP, the first time the Raspberry faction IP address is randomly assigned by the router. Enter the router management page to see.
2, access to IP, Raspberry faction of the default user is pi, the password is raspberry. You can log in with the information above. The specific login tool is logged in via SSH. In the SSH login tool, enter the IP, username and password is OK. If it is a Linux system, you can use the following command to log in. 192.168.
With the upgrade of routing technology, the function of wireless router is also increasing, here mainly analyzes the function of wireless router DD-WRT, the latest 54M wireless router Netgear KWGR614, not only with two 2 DBI detachable antenna, expanded memory, the biggest feature is to support the DD-WRT function, users can brush their own driver, so that this product can play more functions.

◆ If a new computer or mobile phone needs to access the network, access 192.168.1.1 through the computer and configure the MAC access list. Access the management page of the 2nd routers through 192.168.1.99.
The above test of the wireless router relay function is the netgear router-WGR614V9. Of course if you only have one router, the encryption method directly choose WPA2-PSK (AES),
