Prohibit NBT and Microsoft-DS Routing
When this is enabled, you cannot use the Microsoft network
feature from the Internet side to the LAN side and from the LAN
side to the Internet. You can configure this with PPPoE if you
select “Use PPPoE Client” or “Use IP Unnumbered” in Method of
Acquiring IP address (on page 25), or if Easy Setup identified a
PPPoE connection during setup.

Parameter
Meaning
Reject IDENT Requests
Enabling this option will answer IDENT requests from the Internet
side with corresponding rejection packets. Enable this option if
you experienced slower transfer speed for network application
such as sending mail, using ftp or displaying on browser. If
you have configured transfer of IDENT requests to the LAN
side computer in the address translation settings (DMZ or TCP
port:113), that setting has higher priority, and overrides this
setting.
Block Ping from Internet
If this is enabled, the AirStation will not respond to pings from the
Internet side. You can configure this with PPPoE if you select “Use
PPPoE Client” or “Use IP Unnumbered” in Method of Acquiring IP
address (page 26), or if Easy Setup identified a PPPoE connection

Other Tips
Issue:
I reset my wireless router to factory settings and forgot how to log in.
Answer:
Open your browser and enter 192.168.11.1 as the browser address and hit Enter. You will be
prompted to log in. Enter the user name as root and the password box is left empty (no password).
Click "OK" to complete the login and the option to reset your password will be available on the first
page.
Issue:
How do I forward ports on my wireless router for my gaming console?
Answer:
Log in to the router. From the home page, go to the Internet Game/ Port Mapping section. Enter the
port that needs to be forwarded, and the IP address of the gaming console.
Issue:
How do I enable or modify security encryption settings on the wireless router?
Answer:
Log in to the wireless router with your browser. Go to the Wireless Config tab and then select the
Security tab. Buffalo recommends the use of WPA for wireless encryption. The passphrase/key
should be at least 8 characters in length.

Chapter 6 Trouble Shooting
Issue:
How do I change my wireless router's broadcasted network name (SSID)?
Answer:
Log in to the wireless router with your browser. Go to the Wireless Config tab and then select the
Basic tab if necessary. Find the settings area called SSID. Select the "Use" radio button and enter the
name you wish to use for your network in the text field provided. Click "Apply" to save the settings.
Once the wireless router has rebooted, you will need to manually select the new network name for
all wireless devices and enter your encryption key if necessary.
Issue:
What can I do if my wireless connection drops randomly or seems slow?
Answer:
There are many environmental factors that may affect this behavior. First, ensure the issue is not
range related by locating the wireless router and the device dropping connection in closer proximity
and check whether the connection drops continue.
In some cases, interference from other wireless networks or sources such as 2.4 GHz wireless phones
may impact performance. To work around this scenario, change the wireless channel used by your
wireless router.
Log in to the wireless router with your browser. Click on the Wireless Config tab and then the Basic
tab. The Wireless Channel setting can be selected from channels 1 to 11. If an Auto-Channel option
is available, attempt to use this option to remedy the problem. If Auto-Channel is unavailable,
manually select an alternate channel and click "Apply".
Issue:
Though I am able to successfully make a connection with my wireless router, I am unable to access
the Internet with my web browser.
Answer:
First, power off the Cable or DSL modem, the wireless router, and your computer. Move the router's
WCR-GN User Manual
84
Chapter 6 Trouble Shooting
mode switch to the on position. Verify that the modem is connected to the wireless router with an
Ethernet cable to the WAN port.  Power on the modem and wait one minute. Power on the wireless
router and wait another minute. Power on the computer. Open a browser on the computer and
navigate to a familiar website to verify whether the Internet connection is functioning normally.
If after these steps, an Internet connection is still unavailable, power off the Cable or DSL modem
and computer again and directly connect your computer to the Cable or DSL modem with a cable
between the computer and the port on the modem. Power on the modem and wait one minute.
Power on the computer and again check for an Internet connection.
If an Internet connection IS NOT available with a direct connection to the computer, please call the
Internet Service Provider who installed the modem.
If an Internet connection IS available with a direct connection to the computer, please call our
customer support.
