Frequently Asked Questions
GENERAL QUESTIONS
Q1. What is the maximum number of wireless client/users supported by
InterEpoch's Access Points and Brouters?
InterEpoch Access Points
and Brouters support 64 wireless client/users, HOWEVER, we recommend 20~30 client/users
to achieve optimum performance results.
Q2. What's the difference between IEEE 802.1x and RADIUS?
The IEEE 802.1x Port-Based Network Access Control is an IEEE
(Institute of Electrical and Electronics Engineers) standard,
which specifies a standard mechanism for authenticating,
at the link layer (Layer 2), users' access to IEEE 802 networks
such as Ethernet (IEEE 802.3) and Wireless LAN (IEEE 802.11).
For IEEE 802.11 WLAN, IEEE 802.1x authentication can be
based on username/password or digital certificate. In addition,
dynamic distribution of wireless packet encryption keys
can be achieved by IEEE 802.1x. For more information about
IEEE 802.1x, download this presentation.
RADIUS (Remote Authentication Dial-In User Service)
is an IETF (Internet Engineering Task Force) draft standard-- RFC2865 (Request For Comment). It is traditionally used by ISPs
(Internet Service Providers) for authenticating users who
access the Internet using analog/DSL/cable modems. The RADIUS
server communicates with the user database to see if a user
has subscribed to the Internet service.
To provide more security for WLANs, access points should
support both IEEE 802.1x and RADIUS so that wireless users
can be authenticated and packet encryption keys can be automatically
generated and distributed.
InterEpoch's Advanced APs and wireless broadband (switch)
routers support both IEEE 802.1x and RADIUS.

WIRELESS AP / BRIDGE SPECIFIC QUESTIONS
SP1. Which external
antenna do I need for my wireless LAN-to-LAN Bridge?
To determine the best possible external antenna for your
wireless LAN-to-LAN Bridge, please refer to the table below
that outlines the relationship between antenna gains (dBi)
and distances (km):
Gain (Sender) |
Gain (Receiver) |

SP2. There are several model variations--Standard, Pro, and Advanced--for
your wireless broadband (switch) routers. What are the differences
between them?

wireless broadband routers, click HERE.
SP3. Which
antenna of IWE1000A-1 is the "left" antenna?
With the unit facing towards you such that both antennas are
on your left, the antenna in the rear position would be considered
the 'left' antenna.
SP4. When using
an extension antenna on one side, should the default antenna
on the opposite side be removed?
There is no need to remove it. The RF antenna switch automatically
determines and selects an antenna for use based on antenna
RF performance. The extension (high-gain) antenna is always
selected due to its better RF performance compared to hat
of the default antenna.
SP5. I
have two IWE1000A/IWE1000A-1 units. Why do they both have
the same MAC address?
The reason for both units having the same MAC address
is that while using the USB configuration utility, the settings
of one of the units was inadvertently copied. To solve this,
simply run the USB configuration utility and follow these
steps:
- Click Configuration.
- Select the Default Settings option.
- Click Get.
- Select the Configuration Settings option.
- Click Set to restore the MAC address
of the IWE1000A/IWE1000A-1 to its factory-set value.

SP6. What are the meanings of the diagnostic LED indicators on
the IWE1000A/IWE1000A-1?
Please refer to the definitions listed below.
- RX: Unit is receiving data.
- TX: Unit is transmitting data.
- ACT: Unit is active. At present, ACT is always on whether in Tx or Rx mode.
- L+A: Indicates the presence of a 'link' established or there is unit 'activity' occuring.
- F/D: Unit is in full-duplex mode.
- PWR: Unit has power.

WIRELESS ROUTER SPECIFIC QUESTIONS
RQ1. Why does the wireless broadband router fail to dial-up a V.90
modem or ISDN TA?
The most likely reason for the wireless broadband router
failing to properly dial-up a V.90 modem or ISN TA is that
the default AT commands employed by the device for PPP dail-up
may not be compatible with your V.90 modem or ISDN TA. To
solve the problem, consult the user guides of the modem or
TA to find out correct AT commands, and enter them on the
TCP/IP Settings Web management page.
OR
You may send an e-mail detailing the problem and attaching
the modem or TA's Windows driver INF file to support@interepoch.com.tw and we will attempt to determine the AT commands for you.
RQ2. Why does the SS1, ST1, or ALV LED keep blinking?
The SS1, ST1, or ALV LED functions as an "I'm alive"
indicator, so the blinking signifies that the device is working
normally.

WIRELESS ACCESS POINT SPECIFIC QUESTIONS
AP1. Which SNMP traps does the AP support?
The following SNMP traps are supported:
- ColdStart
- WarmStart
- LinkUp
- LinkDown
- SNMP authenticationFailure [To test this trap, the MIB
II OID, snmpEnableAuthenTraps (disabled by default), has
to be enabled first.]
