Why do I need an WLH200?

The WLH200 simplifies the network administrator’s installation and maintenance work associated with the design and setup of a complex user authenticated public access network.  Embedded DHCP server, Authentication Server, User Data Base, Network Address Translation, Web Based Remote Management and RADIUS Client all integrated into one box makes configuration and maintenance simple for a network administrator

The WLH200 is suitable for deploying fee based Internet services to public users in hotels, airports, and other hotspots, as well as, controlled network access to campus resident housing, multi-dwelling units and corporate office locations.

The WLH200 simplifies the user’s experience when accessing high speed Internet services by enabling instant plug and play without having to alter existing IP configurations of the user’s PC.  The WLH200 automatically accommodates fixed IP, DHCP client, or private IP settings, and automatically redirects a first time user to a log-in page for authenticating their username and password. Once accepted, the user is allowed through to the network.

  Where can you use the WLH200?

Any public network where USER AUTHENTICATION is a primary concern.  Authentication pages are presented to the end user via a web page so no special authentication software needs to be installed on the end user’s PC – all Internet access and authentication is done through the user’s web browser.

Hospitality:  hotels, resorts, convention centers

Institutional facilities:  primary schools, university campuses, libraries

Healthcare facilities:  clinics and labs, hospitals, medical group facilities

Multi-dwelling / multi-tenant:  apartments, condominiums, professional buildings, strip malls

Hotspots:  airports, cafes, public spaces (parks, malls, event pavilions)

What benefits does the WLH200 bring to  the Service Provider?

Ease of installation. The WLH200 integrates with a facility’s original network architecture.  The WLH200 supports wired or wireless Ethernet LAN devices via a 10/100 Mbps Ethernet port. .

Affordable and simple to maintain. Authentication features are integrated in one rack mountable device cabinet.  Remote Management also includes confidential administrative login to browser based setup pages.

Scalable. WLH200 can maintain thousands of authenticated users and provides RADIUS client support for access to corporate database resources.

How does a PUBLIC user access Internet services using the WLH200 system?

  1. Connect their PC to the Ethernet LAN port (via a network, whether wired or wireless)
  2. Open an Internet browser (i.e., MS Explorer, Netscape Navigator)
  3. Enter their username and password (provided to them)

Once the login is authenticated, the end user may access network resources, including Internet access, etc…

Can I install WLH200 on a legacy network already setup and running ?

Yes.  The WLH200 connects, typically on the LAN side of a facility router, in any existing Ethernet network.  After WLH200 is installed, all clients connecting on the LAN side of the WLH200 will immediately require “first time” authentication.  Once authenticated, the WLH200 becomes transparent to the network user.

Can I use wireless networks with the WLH200?

Yes.  As long as the network interface to the WLH200 is Ethernet, the structure of the LAN network, whether wired or wireless, does not matter.  The only requirement is an Ethernet port interface.

What additional devices do I need for WLH200 setup?

None.  The device features and functionality are completely integrated in the single rack mount cabinet.  A PC running a standard browser is used to access the configuration pages. 

How many PC clients (users) can be supported on the WLH200 network?

Up to 1024 clients can be connected to the network simultaneously within the WLH200 network.

What is meant by "Plug and Play" experience with the WLH200?

For mobile PC users, the WLH200 provides instant Internet access by automatically accommodating their current PC network settings and redirecting their browser to available services. As a result, the end user simply plugs into the network.  The WLH200 discovers the presence of a new client and automatically initiates the login process when the user opens their web browser. 

Can I control the user’s connection time and account usage?

The WLH200 supports both local authentication and server based RADIUS.  RADIUS enables ISPs to maintain large central databases of users (potentially in the millions). WLH200 includes PMS support for local usage tracking to allow time of use billing options. 

How does an administrator control the end user’s login authentication?

The WLH200 provides an internal proprietary authentication server, which allows complete administrative control over local LAN user login name and password acceptance. 

Does a dedicated PC station have to be used to access the configuration pages?

No.  The WLH200 configuration pages can be accessed from any PC using a Web browser, whether on the same subnet or from a remote location on the Internet.  Rights to access the configuration pages are password protected. 

Can I redirect the end user’s browser homepage while connected to the WLH200’s network?

Yes.  If it is desired to have the client guest view a specific URL upon launching their browser, the WLH200 can be configured to manage this experience.  The WLH200 redirects the browser to a “first page,” as may be desired to show a facility orientation or services page, or for advertisement purposes. 

Will the ISS2000 affect Email functionality for the end user?  

Yes.  The WLH200 will rewrite a user's original outbound message according to SMTP rules and send it via a specified Email server. This function enables the sending of Email when, in many cases, the user’s email server through their ISP is unavailable from a different location.  This requires the availability of a dedicating Email server provided by the facility.

What radio frequency does the WLA660 use?  Is it regulated?

In the U.S., wireless LAN radios transmit and receive on one of 13 channels in the 2.4-GHz frequency band. This is a public band, and does not require a license from the FCC

How do I secure the data crossing an AP's radio link?

The WLA660 supports Wired Equivalency Protocol (WEP) to encrypt the payload of packets sent  across a radio link. Two levels are available, 40 and 128 bit, for the WEP settings. 

What security features does the WLA660 support?

  • SSID: Service Set Identifier, a 32-character unique identifier attached to the header of packets sent over a WLAN that acts as a password when a mobile device tries to connect to the AP
  • Broadcast SSID: Enable or disable the “Broadcast SSID” option. Blocks a connection request from a device without the correct SSID and “hides” the SSID in outgoing beacon frames. A site-survey tool will not find the SSID.
  • Data security: The AP supports 40-bit and 128-bit Wired Equivalent Protocol (WEP)
  • Management Security: SNMP Access Control

What are possible sources of interference for the radio frequency link of the AP?

AP’s with overlapping coverage and improperly spaced channel frequencies can cause interference between the AP’s. In addition, interference can come from a number of other sources, including 2.4-GHz cordless phones, improperly shielded microwave ovens, and wireless LAN equipment manufactured by other companies. Police radar, electric motors, and moving metal parts of machinery can also cause interference. 

How do I secure the data crossing an AP's radio link?

The WLA660 supports Wired Equivalency Protocol (WEP) to encrypt the payload of packets sent across a radio link. Two levels are available, 40 and 128 bit, for the WEP settings. 

What should be considered when installing the AP?

The physical location for the WLA660 should be selected to allow for the following 

  • For roaming cells, maintain a distance between Access Points of about 35 meters. The closer the APs are together, the farther apart the radio channel spacing should be (e.g. CH1 – CH13). Where there is no overlapping of AP coverage, then any channel can be used, including ones that have been selected for other APs.
  • In most cases, APs should be placed in the geographical center of the coverage area.
  • Access to an A.C. outlet for the power adapter
  • Placement of a remotely attached high gain antenna to minimize connecting cable length
  • If the default dual dipole antenna is used, placement where no metal structures block line of site transmission to the desired coverage area

What is the connector type for the antenna?

The antenna connector for the WLA660 is a reverse SMA (RPSMA) female type. This connector accommodates the standard dual dipole antenna included with the unit, or a remotely attached high gain antenna.

What is the speed of the AP's Ethernet port?

The WLA660's Ethernet port (RJ-45 jack) supports 10 Mbps over a 10Base-T connection (half-duplex only). 

What indicators are available on the front panel?

There are four LED indicators on the front panel, including: Power, Status, Ethernet link, and Wireless link. 

How do I set the AP back to its factory default settings?

The default settings can be loaded from a menu selection in the IWMS utility, or the reset button on the back panel of the AP can be pressed. 

What is IWMS used for with the WLA660?

IWMS management software provides a Web browser interface and various utility functions for managing the AP as part of a network. IWMS uses SNMP to monitor, configure and troubleshoot the operation of multiple APs simultaneously 

Is IWMS management software required to install and setup the WLA660?

No.  For initial installation, the WLA660 includes a COM port (RS-232 cable included) and COMFig utility for performing initial setup configuration prior to introducing the AP to an existing network but configuration management is also possible over the air using IWMS.

Does WLA660 support roaming?

Yes.  When deployed in multiple AP networks, the WLA660 can be configured to allow a mobile client (e.g., a user’s laptop) to move throughout the coverage area with seamless connectivity. This requires a careful site survey during the installation phase to assure proper overlapping cell coverage between APs. 

Is the WLA660 upgradeable in the field?

Yes.  The WLA660 supports upgrades of its firmware on demand. The process can be done with individual units through the AP’s COM port, or remotely via wireless, using IWMS management software. The upgrade process may be conducted at any time, while the unit remains connected to the network. SOHOware provides new firmware from time to time at its web site. 

Troubleshooting

This section provides you with some troubleshooting info should you encounter installation or operation problems on SPAN products.

Symptom: The WLA660 is switched on, but the Power LED on the WLA660 is off.

Make sure the power adapter is firmly connected to the power outlet and the WLA660 power connector.

  1. The power adapter or WLA660 is defective.

Symptom: The IWMS utility cannot detect the WLA660 on the same network.

  1. Make sure the WLA660 is powered on and connected to an Ethernet network.
  2. Check the IP addresses assigned to the WLA660 and IWMS terminal PC. They should be in the same subnet and unique. For example, if the WLA660’s IP address is 192.168.1.5 with a mask of 255.255.255.0, then the PC’s IP address should be 192.168.1.x with a mask of 255.255.255.0.

Symptom: The WLA660 powers up, but the Ethernet Link LED is off (no connection to an Ethernet network).

        Make Sure

  1. The Ethernet cable is connected firmly to both the AP and hub or switch.
  2. The Ethernet hub or switch is powered on.
  3. The device you are trying to connect to the WLA660 requires a cross-over cable

Symptom: The Status LED on the WLA660 front panel is red and flashing.

WLA660 does a POST (power on self test) and one of the self-tests has failed. Restart (power-cycle) the WLA660 and check the Status LED again. If it is still flashing, you need to return the WLA660 to the reseller for repair.

Symptom: Transmission performance is slow or erratic.

  1. Change the direction of the antenna slightly.
  2. There may be interference, possibly caused by a microwave oven, 2.4-GHz wireless phone, or metal objects. Move these interference sources or change the location of the wireless PC or AP.
  3. Change the wireless channel on the WLA660.
  4. Check that the WLA660 antenna, connectors, and cabling are firmly connected.
  5. Check for metal obstructions between the WLA660 and the station PC.

What radio frequency does the WLC261 WEC use?  Is it regulated?

In North America, wireless LAN radios transmit and receive on one of 11 channels in the 2.4-GHz frequency band. This is a public band, and does not require a license from the FCC. . In Europe and China, there are 13 channels to choose from, while Japan has 14. In order for these channels to experience minimal interference, the AP’s should be set to different channels so they do not disturb each other’s signal    

How do I secure the data crossing the radio link between the WLC261 and an AP?

The WLC261 supports Wired Equivalency Protocol (WEP) to encrypt the payload of packets sent across a radio link. Two levels are available, 40 and 128 bit, for the WEP settings. In addition, it is recommended that the default SSID on the Access Point and NWH2610 be changed to a confidential name

Can a device other than a PC, such as an Ethernet-equipped printer, be connected to the WLC261 to provide a wireless interface? 

Yes.  Any device with Ethernet capability can be connected to the client port of the WLCH261 WEC, including servers, printers, scanners, web cams and PDA’s. The WEC must be set to activate its wireless interface automatically upon power-up, and to keep that interface active all the times. Do this as follows: 

  1. Go to the WEC Utility's Configuration panel and choose Ethernet. The Ethernet Access Control dialog box will appear
  2. Under Idle Time, select (enable) the "Always Connect" option.

To test the configuration, connect a test device to the WEC’s Ethernet port and "ping" the test device from a PC station on the network.

Does a PC need to have pre-configured Network settings prior to connecting to the WLC261?

No. The WEC accommodates any existing network settings, including static or DHCP addresses. A PC can be connected and obtain immediate access to the network with no pre-configuration

Should the WLC261 be pre-configured before connecting to a network?

Generally no, since the default settings of the WEC allow it to automatically connect to an AP in the vicinity. An exception would be if the AP (e.g., WLA660) that the WEC connects to has been configured with particular settings for WEP security or a new SSID name. If yes, then the WLC261 should be pre-configured using the IWMS utility via a PC connected to WEC’s Ethernet port to modify the default settings to the particular settings of the AP

What is the speed of the WLC261's Ethernet port?

The WEC's Ethernet port (RJ-45 port) supports 10 Mbps over a 10Base-T connection (half-duplex only)

What indicators are available on the front panel?

There are two LED indicators on the front end of the unit, including: Status and Wireless link. 

How do I set the WLC261 back to its factory default settings?

The default settings can be loaded from a menu selection in the IWMS utility, or the reset button on the back panel of the WEC can be pressed. 

I cannot discover my WLC261 WEC using the IWMS utility.

  1. Make sure the WEC is powered on and connected to the Ethernet network.
  2. Check that the IP address of the PC station running IWMS is on the same subnet (identical subnet mask) as the IP address assigned to the WEC. The IPs should be unique as well.
  3. If the IP address of the WEC is unknown, reset the WEC by depressing the reset button on the back of the unit to obtain the factory default setting.
  4. Perform a Release / Renew of the IP settings of the PC running IWMS. For Windows based PCs, this is conducted as follows:

    Windows 98/ME

    Step

    1. Click Start/Run, type "winipcfg", and click . The IP Configuration dialog box will open.
    2. Select the network adapter you use to connect to the WWB/WEC Pro or Ethernet work. Click .
    3. Click to retrieve a new IP address, subnet mask, and default gateway address. Click to save the changes and exit the program.

      Windows NT 4.0

      Step

      1. Click Start/Programs/Command Prompt. Type "ipconfig /release" and press Enter key.
      2. Type "ipconfig /renew" and press Enter key to retrieve a new IP address, subnet mask, and default gateway address.
      3. Type "Exit".


      Windows 2000/XP

      Step

      1. Click Start/Programs/Accessories/Command Prompt. Type "ipconfig /release" and press Enter key.
      2. Type "ipconfig /renew" and press Enter key to retrieve a new IP address, subnet mask, and default gateway address.
      3. Type "Exit".

      Note: If there is no DHCP server in your Ethernet network or the WEC cannot obtain an IP address from a DHCP server, the WEC will auto-assign an IP address of 169.254.x.x with a subnet mask of 255.255.0.0. A Windows OS PC originally configured as a DHCP client will follow the same algorithm to assign itself an Auto-IP address in the same subnet.

Why do I need IWMS?

For commercially deployed networks that encompass many devices, IWMS provides an effective tool for administrators to manage and maintain the entire LAN from a single PC station. The software utility configures SOHOware SPAN wireless devices over the air. IWMS monitors the online status of the network and each network device.

How does IWMS obtain information from devices on the LAN?

IWMS uses SNMP (Simple Network Management Protocol) to allow the configuring, monitoring and maintenance of SNMP enabled devices on the LAN. The resulting value for administrators is that IWMS is a power tool for managing the entire network from one PC station. 

Can IWMS manage wireless devices on the network? 

Yes. IWMS can view devices on a wired LAN and/or wireless LAN, as long as the devices are all on the same subnet (same subnet mask). In addition, the devices must be SNMP enabled, as in SOHOware’s SPAN solutions

Is each device configured individually?

Each device on the network can be viewed individually, and configured either individually or in a BATCH. To manage networks with multiple same type devices (e.g., multiple Access Points), IWMS batch configuration allows for the simultaneous distribution of one configuration file. All devices of the same type may be selected, then targeted with one update.

Can alarms be set to warn of problems with a particular device?

Yes.  The SNMP functionality includes a Trap Server for defining online status and performance limits. As a result, each device can be monitored in real-time, with definable performance limits set by the administrator for when to trigger notification 

I cannot discover a NWH2610 WEC using the IWMS utility.

  1. Make sure the WEC is powered on and connected to the Ethernet network.
  2. Check that the IP address of the PC station running IWMS is on the same subnet (identical subnet mask) as the IP address assigned to the WEC. The IPs should be unique as well.
  3. If the IP address of the WEC is unknown, reset the WEC by depressing the reset button on the back of the unit to obtain the factory default setting.
  4. Perform a Release / Renew of the IP settings of the PC running IWMS. For Windows based PCs, this is conducted as follows:

    Windows 98/ME

    Step

    1. Click Start/Run, type "winipcfg", and click . The IP Configuration dialog box will open.
    2. Select the network adapter you use to connect to the WWB/WEC Pro or Ethernet work. Click .
    3. Click to retrieve a new IP address, subnet mask, and default gateway address. Click to save the changes and exit the program.

      Windows NT 4.0

      Step

      1. Click Start/Programs/Command Prompt. Type "ipconfig /release" and press Enter key.
      2. Type "ipconfig /renew" and press Enter key to retrieve a new IP address, subnet mask, and default gateway address.
      3. Type "Exit".


      Windows 2000/XP

      Step  

      1. Click Start/Programs/Accessories/Command Prompt. Type "ipconfig /release" and press Enter key.
      2. Type "ipconfig /renew" and press Enter key to retrieve a new IP address, subnet mask, and default gateway address.
      3. Type "Exit".

      Note: If there is no DHCP server in your Ethernet network or the WEC cannot obtain an IP address from a DHCP server, the WEC will auto-assign an IP address of 169.254.x.x with a subnet mask of 255.255.0.0. A Windows OS PC originally configured as a DHCP client will follow the same algorithm to assign itself an Auto-IP address in the same subnet.

When running IWMS in Windows 95, a "Divide Error" message is generated.

one.  Once IWMS is installed, reboot the PC station, even if Windows does not require this step. IWMS should function normally after the reboot.
