How can I recover forgotten passwords or recall the factory defaults on
the base station?
A. Because there is no password setup on the base station, you must reset
the base station to the factory defaults by pressing the Reset
pinhole button for two seconds. When you press this reset, you reset the unit
to its default, out-of-the-box state.
Why does the middle Status LED always blink yellow or
A. The base station starts with default Service Set Identifier (SSID) and
Encryption settings. When a yellow or amber light blinks it is a visual alert
that you have not personalized your installation or changed the factory default
settings. When you change the SSID or Encryption settings, you change the
Status LED to blink or solid green.
What speed is the Ethernet port of the base
A. The Ethernet port of the base station supports 10 Mbps in half-duplex
mode over a 10BaseT RJ-45 connector. There is no option to change the speed and
duplex settings on the LAN port.

station depends upon the speed:
100 ft (30m) at 11 Mbps
300 ft (90m) at 1 Mbps
300 ft (90m) at 11 Mbps
1000 ft (300m) at 1
Can I roam between base stations?
A. No, no roam function is built into the base station.
How can I manage the base station?
A. The base station does not have a console connector. Configure the base
station with one of these methods:
Install the Base Station Client Utility (BSCU) on the Wireless
client. Ensure that the client gets an IP address through DHCP from the base
station. This IP address must be in the 192.168.200.x
range. Then launch BSCU and configure the base station.
Type http://192.168.200.1 into the
Address or Location field of your web
browser. The base station comes pre-configured with this IP address. When this
IP address is typed into the browser, a connection with the base station is
Issue the telnet command at a command
prompt, as shown:
> telnet 192.168.200.1
How many clients can I associate to the base
A. You can associate a maximum of 253 clients to a base station. You can
lease 100 IP addresses from the DHCP server of the base station. Additional
clients must use static IP addresses between 192.168.200.102
Can a base station associate with a Workgroup
A. Yes, a Workgroup Bridge and a base station can associate with each
other if the base station is in Access Point mode.
Where can I find the radio frequency (RF) association
A. A base station association table is not maintained, but you can check
the association when you view the Log and Alarm History menu
from the base station homepage or from the menu in the Base Station Client
Why does the base station not accept changes set through a
A. When you modify the configuration through a browser, you must press
Enter after you set each parameter.
When I try to set up my base station to use my PPP over Ethernet (PPPoE)
Asymmetric Digital Subscriber Line (ADSL), and I am asked for a “service name.”
What is a service name, and where do I find it?
A. The service name is the domain name of your Internet Service Provider
(ISP). For example, the service name for Cisco would be
cisco.com. It may also be the name of the ADSL device at the
end of your connection for the provider. For example, if Cisco had an ADSL
concentrator named 192.168.1.1-sj_ca.6400.dslam1.cisco.com
that physically provided your ADSL service, you would use the name
6400.dslam1 as your service name. Your ISP can provide this
configuration information based on the services that you have on the phone
If I use the Base Station Client Utility (BSCU) to change the settings of
the base station (for example, the Service Set Identifier [SSID]), will the
client be de-associated?
A. No, BSCU changes the settings of the client that transmitted the change
as well as the settings of the base station itself. Other clients, however, may
be de-associated, but that depends on the parameter that is changed.
Can I use static IP addresses on wireless and wired
A. Yes, you can use static IP addresses in the
192.168.200.102 to 192.168.200.254
Can I change the internal IP address (192.168.200.1) or the DHCP address
pool (192.168.200.2-101) of the base station?
A. No, the internal IP address and DHCP address pool are not
How can I find the external or DHCP IP address of a base
A. You can use the web interface to locate the external or DHCP IP address
at the bottom of the base station homepage or inside the Log and Alarm
How long does a DHCP lease from the base station
A. A DHCP lease from the base station lasts for one day.
Why can I not browse or use Telnet to access the base station at its
external IP address?
A. The base station is designed to prevent Telnet or browser connections
for security reasons. Although you can not connect to the IP address, you can
use the ping command to verify that the base station
is alive on the network. You can only use a web browser or Telnet to access the
internal IP address of the base station
Can I set up MAC address filters or association filters on the base
A. No, filtering is not available on the base station.
Do the base station and Base Station Client Utility (BSCU) support 40-bit
Wired Equivalent Privacy (WEP) encryption?
A. No, they only support 128-bit WEP encryption or no encryption.
In the Base Station Client Utility (BSCU), what happens if the
Hexadecimal Wired Equivalent Privacy (WEP) key is entered with fewer than 26
A. The WEP key has a default null character (00 hexadecimal) that it
appends to the key to maintain 26 characters for 128-bit WEP keys.
What is the WEP authentication type for the base station and a client
with Base Station Client Utility (BSCU)?
A. It is hard-coded to Open Authentication. It can not be changed.
I forgot the WEP key that has been set up on some clients and base
stations. Can I use the same WEP key for a new client without overriding the
WEP keys that work?
A. Yes, you can duplicate the WEP key without decrypting it by using the
Base Station Client Utility (BSCU) on the WEP-enabled client. Complete these
steps to duplicate the WEP key:
From the BSCU menu of a client that has the desired WEP key, choose
Options > Install Additional Computer > Save to Floppy
Save the configuration file on a floppy disk.
From the BSCU menu of the new client, choose Clients >
Edit Client Properties > Load from Floppy
Select the configuration file from the floppy
Does the base station modem support the V.90
Why does my base station modem not ring when I
A. The base station does not have a modem speaker. You can check the dial
status and dial results from the client utility when you access the Base
Station Connection Status (BSCS) utility or the Log and Alarm
History menu on the base station. For more information, refer to
Station Connection Status Utility.
Why will the base station (modem) not connect to America
A. America Online dialup connections do not use industry-standard PPP
negotiation methods. The base station uses PPP only and can only connect to
dialup Internet Service Providers (ISPs) that use PPP.
