3 Product Description
PePLink Surf, formerly known as MANGA Surf, is a Wi-Fi Station Mode (Client)
Router with WPA, WPA2 and 802.1x supplicant support. It is designed to
act as a Wireless router which connects to Wireless Broadband Internet
Service and allows LAN users to access the Internet via it.
It associates to a service provider and authenticates using 802.1x (if needed)
on start up. Upon successful association and authentication, it will acquire
an IP address from the service provider using DHCP. A DHCP server is
built-in on its LAN port. Network Address Translation is performed for all
outbound connections. Thus it supports multiple terminals to access the
Internet simultaneously.
3.1 Features
• 10/100 Ethernet interface with auto-crossover detection
• Reset button for restoring settings to factory defaults
• Signal strength LED for showing the current signal strength
• WPA/WPA2-Personal and WPA/WPA2-Enterprise support
• Network Address Translation
(NAT) routing
• Built-in DHCP server
• Inbound port range forwarding

enabled, the IP address range can be configured.
Wireless Settings:
SSID: To configure the SSID / ESSID / Network Name of the wireless
network to associate to.
Radio Mode: It allows the user to choose between radio modulations
support. E.g. 802.11b/g, 802.11g only, 802.11b, etc. The available
settings depend on the Wi-Fi module installed on the device.
Note: Under 802.11
g
only mode, 802.11b rates are used durin
g
access point association.

Bit Rate: To fix the 802.11 transmit bit rate. Available options depend on
the Radio Mode chosen. If “auto” is chosen, the device will choose the best
bit rate dynamically and automatically.
Authentication: Available options are Open, Static WEP Key, 802.1x with
dynamic WEP key, WPA/WPA2-Enterprise and WPA/WPA2-Personal. The
selection should be according to the setting of the access point you are
associating to. Data transferred are encrypted under all modes except the
Open mode. When Static WEP Key or WPA/WPA2-Personal is chosen, you
should enter an encryption key in the Encryption Key field. For 802.1x and
WPA/WPA2-Enterprise options, please refer to chapter 4.4 .
Preferred AP: The MAC address of a preferred access point can be entered
here. When the preferred access point is found and its signal strength is
higher than the “Min Signal Strength”, it will connect to this preferred access
point, no matter the other access points are found even they have higher
signal strength or the same SSID.
WAI redirection: If the device is not connected to an access point, and the
user is accessing an Internet web site, the settings control whether to
redirect the web access to the web admin interface page or not. If this is
disabled and the device is not connected, the browser will then show web
access error. The user can still access the web admin interface by
accessing to the device’s LAN IP address. By default, it’s
http://192.168.20.1 .
Restore factory settings: To restore the device to factory default settings.
After clicked, the settings will be restored to factory defaults and the device
will be restarted.
Reboot: To restart the device.

4.4 WPA/WPA2 with 802.1x Authentication
The PePLink Surf supports authentication and encryption methods of
“802.1x with dynamic WEP key encryption” and WPA/WPA2-Enterprise. A
radius server can be used to perform authentication based on the IEEE
standard 802.1x with EAP-TTLS.
To set it up, you have to configure the PePLink Surf, the access point and a
radius server.
By default, EAP-TTLS/CHAP is used as the EAP authentication method. You
can change this setting in the System Settings page. Please refer to
chapter 4.9.3 .
4.4.1 Configure the PePLink Surf
To enable the 802.1x authentication, you can go to the CPE Setup page,
choose “WPA” for the Authentication setting and leave the WEP key setting
empty.
Certificate checking
By default, the PePLink Surf does not verify the radius server’s
certificate. If you would like to check the certificate, you can use a
command-line based FTP client to upload your certificate to the
PePLink Surf.
1. ftp to the PePLink Surf (default IP is 192.168.20.1)
2. Type the login ID and password: “root” and “MSurf000
”
3. cd /etc/1x
4. put root.pem
5. bye

4.4.2 Access Point
Access point set up procedure is different from one brand to the others.
Here are some necessary configuration parameters to be configured in the
access point:
- Enable WPA2 with 802.1x authentication
- Enter the radius server IP address, port number and the secret (for the
provided radius server config mentioned in 4.4.3 , the secret is
“testing123”)
4.4.3 Radius Server
The commercial radius server, Radiator, is used in the set up. It is a product
of Open System Consultants Pty Ltd.
Radiator version 3.9 is known to be interoperable. Any version above 3.9
should work too. Just follow the server’s installation guide to install it on a
server.
After installed, you should put the root cert file and server cert file to a
directory, update radiator’s configuration file and the users files.
A demo CA cert file (cacert.pem), a server cert file (server_cert.pem) and
a server key file (/etc/radiator/server_key.pem) are pre-generated and
attached. You can generate them by yourself by following the instructions
in the Appendix. Put the files to the directory /etc/radiator.
A sample Radiator configuration file is as follows. Save it as radius.cfg
and put it under /etc/radiator.
