Solve the Problem of connecting to ChinaUnicom on Ubuntu

At three o'clock this morning, I was very excited when I installed the MINT and WIN7 systems on this book, but at the same time, various problems also followed. The first problem is Internet access! In WIN7, I use ChinaUnicom, 8 M bandwidth, which is very convenient. But on LINUX, I don't know how to get started. To access the Internet, you must first connect to ChinaUnicom and then dial. After my unremitting efforts with my classmates, I first solved the dialing problem, and then solved the tangled problem of connecting to Unicom! The method is as follows:

In WIN7, I use ChinaUnicom, 8 M bandwidth, which is very convenient. But on LINUX, I don't know how to get started. To access the Internet, you must first connect to ChinaUnicom and then dial. After my unremitting efforts with my classmates, I first solved the dialing problem, and then solved the tangled problem of connecting to Unicom!

The method is as follows:

Let's talk about the most difficult connection to Unicom!

In fact, it is very simple. When using wlan0 to connect to ChinaUnicom, you must manually set the IP address. By default, the www.linuxidc.com system assigns an IP address automatically through DHCP. This is similar to WINDOWS. I use DHCP to connect to the network on WINDOWS. However, this is Linux.

The IP address can be set as follows:

Ip 192.168.1.100

Mask limit 255.0

Maybe the gateway and DNS can be matched on the Internet. I tried to connect it to Unicom but cannot access the Internet. We recommend that you only write the first two items. The ip address does not affect dial-up. You can write it as needed. It only allows the wireless network adapter to connect to the chinaunicom AP without Automatically Obtaining the ip address and connecting to the AP.

Then there is a dialing problem.

On WINDOWS, we use the Netcom client. pppoeconf is used here.

1> enter pppoeconf wlan0 in the command line.

2> during configuration, all options can be set by default. You only need to enter the user name and password.

Wlan0 is your wireless network card and must be connected to ChinaUnicom

In this way, you can connect to the Internet, and the network speed is still wrong ~

When you start the instance next time, enter the following command in the command line:

# Pon dsl-provider dialing to establish a connection

When not in use, you can enter the following in the command line:

# Poff network disconnection, Saving network fees

You 'd better write the MAC address of your wireless network card
