The way is connecting Internet through wireless device by command.
I attempt to find out any solution of GUI, but no available.
If you don’t like use command,please forget about this post.

Then choose ifup method

Below is an example:
==Access Point==
ip address: 192.168.1.1
ssid: AP11
channel: 1

==Client==
assigned ip address: 192.168.1.111

#iwconfig

You are able to connect to access point now.

#pppoe-setup

Welcome to the Roaring Penguin PPPoE client setup. First, I will run
some checks on your system to make sure the PPPoE client is installed
properly…

Looks good! Now, please enter some information:

USER NAME

>>> Enter your PPPoE user name (default): < --type your username of pppoe account

INTERFACE

>>> Enter the Ethernet interface connected to the DSL modem
For Solaris, this is likely to be something like /dev/hme0.
For Linux, it will be ethn, where ‘n’ is a number.
(default eth0): < ---type wlan0 that is your wireless deivce

MODEM TYPE

We will try to detect if your modem is compliant with RFC 2516
or not. 3COM’s 3CP4130 is *NOT* compliant, for instance.

Searching for a modem at interface wlan0…

Not found, trying with 3COM’s code…

Didn’t find a modem at interface wlan0, you can continue but
things might not work as you expect…
You might want to re-run this script and try a different interface.

Do you want the link to come up on demand, or stay up continuously?
If you want it to come up on demand, enter the idle time in seconds
after which the link should be dropped. If you want the link to
stay up permanently, enter ‘no’ (two letters, lower-case.)
NOTE: Demand-activated links do not interact well with dynamic IP
addresses. You may have some problems with demand-activated links.
>>> Enter the demand value (default no): < ---Enter

Please enter the IP address of your ISP’s primary DNS server.
If your ISP claims that ‘the server will provide DNS addresses’,
enter ’server’ (all lower-case) here.
If you just press enter, I will assume you know what you are
doing and not modify your DNS setup.
>>> Enter the DNS information here: < ---Enter

PASSWORD

>>> Please enter your PPPoE password: < ---type your password of pppoe account
>>> Please re-enter your PPPoE password: < ---type your password again
FIREWALLING

Please choose the firewall rules to use. Note that these rules are
very basic. You are strongly encouraged to use a more sophisticated
firewall setup; however, these will provide basic security. If you
are running any servers on your machine, you must choose ‘NONE’ and
set up firewalling yourself. Otherwise, the firewall rules will deny
access to all standard servers like Web, e-mail, ftp, etc. If you
are using SSH, the rules will block outgoing SSH connections which
allocate a privileged source port.

The firewall choices are:
0 – NONE: This script will not set any firewall rules. You are responsible
for ensuring the security of your machine. You are STRONGLY
recommended to use some kind of firewall rules.
1 – STANDALONE: Appropriate for a basic stand-alone web-surfing workstation
2 – MASQUERADE: Appropriate for a machine acting as an Internet gateway
for a LAN
>>> Choose a type of firewall (0-2): < ---type 0

** Summary of what you entered **

Ethernet Interface: wlan0
User name: 71355589@hinet.net
Activate-on-demand: No
DNS: Do not adjust
Firewalling: NONE

>>> Accept these settings and adjust configuration files (y/n)? < ---type y

Congratulation! you can start to connect to internet via pppoe-start command now.

# pppoe-start
… Connected!

PS: Here are all of pppoe configuration files.
#cd /etc/ppp/
