Troubleshooting

This Appendix covers the most likely problems and their solutions.

Overview

This chapter covers some common problems that may be encountered while using the LevelOne Wireless Broadband Router and some possible solutions to them. If you follow the suggested steps and the LevelOne Wireless Broadband Router still does not function properly, contact your dealer for further advice.

General Problems

Problem 1:
Can't connect to the LevelOne Wireless Broadband Router to configure it.
Solution 1:
Check the following:
  • The LevelOne Wireless Broadband Router is properly installed, LAN connections are OK, and it is powered ON.
  • Ensure that your PC and the LevelOne Wireless Broadband Router are on the same network segment. (If you don't have a router, this must be the case.)
  • If your PC is set to "Obtain an IP Address automatically" (DHCP client), restart it.
  • If your PC uses a Fixed (Static) IP address, ensure that it is using an IP Address within the range 192.168.0.2 to 192.168.0.254 and thus compatible with the LevelOne Wireless Broadband Router 's default IP Address of 192.168.0.1.
    Also, the Network Mask should be set to 255.255.255.0 to match the LevelOne Wireless Broadband Router.
    In Windows, you can check these settings by using Control Panel-Network to check the Properties for the TCP/IP protocol.

Internet Access

Problem 1:
When I enter a URL or IP address I get a time out error.
Solution 1:
A number of things could be causing this. Try the following troubleshooting steps.
  • Check if other PCs work. If they do, ensure that your PCs IP settings are correct. If using a Fixed (Static) IP Address, check the Network Mask, Default gateway and DNS as well as the IP Address.
  • If the PCs are configured correctly, but still not working, check the LevelOne Wireless Broadband Router. Ensure that it is connected and ON. Connect to it and check its settings. (If you can't connect to it, check the LAN and power connections.)
  • If the LevelOne Wireless Broadband Router is configured correctly, check your Internet connection (DSL/Cable modem etc) to see that it is working correctly.
Problem 2:
Some applications do not run properly when using the LevelOne Wireless Broadband Router.
Solution 2:
The LevelOne Wireless Broadband Router processes the data passing through it, so it is not transparent.
Use the Special Applications feature to allow the use of Internet applications which do not function correctly.
If this does solve the problem you can use the DMZ function. This should work with almost every application, but:
  • It is a security risk, since the firewall is disabled.
  • Only one (1) PC can use this feature.

Wireless Access

Problem 1:
My PC can't locate the Wireless Access Point.
Solution 1:
Check the following.
  • Your PC is set to Infrastructure Mode. (Access Points are always in Infrastructure Mode)
  • The SSID on your PC and the Wireless Access Point are the same.
    Remember that the SSID is case-sensitive. So, for example "Workgroup" does NOT match "workgroup".
  • Both your PC and the Wireless Access Point must have the same setting for WEP. The default setting for the LevelOne Wireless Broadband Router is disabled, so your wireless station should also have WEP disabled.
  • If WEP is enabled on the LevelOne Wireless Broadband Router , your PC must have WEP enabled, and the key tables (for 64 Bit encryption) or key (for 128 Bit encryption) must match.
  • If the LevelOne Wireless Broadband Router 's Wireless screen is set to Allow LAN access to selected Wireless Stations only, then each of your Wireless stations must have been selected, or access will be blocked.
  • To see if radio interference is causing a problem, see if connection is possible when close to the Wireless Access Point.
    Remember that the connection range can be as little as 100 feet in poor environments.
Problem 2:
Wireless connection speed is very slow.
Solution 2:
The wireless system will connect at the highest possible speed, depending on the distance and the environment. To obtain the highest possible connection speed, you can experiment with the following:
  • Access Point location.
    Try adjusting the location and orientation of the Access Point.
  • Wireless Channel
    If interference is the problem, changing to another channel may show a marked improvement.
  • Radio Interference
    Other devices may be causing interference. You can experiment by switching other devices Off, and see if this helps. Any "noisy" devices should be shielded or relocated.
  • RF Shielding
    Your environment may tend to block transmission between the wireless stations. This will mean high access speed is only possible when close to the Access Point.

Printing

Problem 1:
When I tried to install the Printing software for Peer-to-Peer printing, I received an error message and the installation was aborted..
Solution 1:
This may be caused by an existing installation of the printer port software. Before attempting another installation:
  • Remove the existing installation
  • Restart your PC
To remove an existing printer port installation:
  1. Open Start - Settings - Control Panel - Add/Remove Programs
  2. Look for an entry with a name like "Shared Port", "Shared Printer Port", "Print Server Driver" or "Print Server Port".
  3. Select this item, click "Add/Remove", and confirm the deletion.
Problem 2:
I am using Windows 95, and the Printing software installed and ran, but when I selected a port on a LevelOne Wireless Broadband Router and clicked "Add", the printer was not installed.
Solution 2:
Try installing the printer using the standard Windows tools, as follows:
  1. Start the Add Printer Wizard.
  2. Select Network Printer when prompted "How is the printer attached to your Computer?", and click Next.
  3. When prompted for the Network Path or Queue, enter a dummy value such as \\123, as shown below. (Do NOT select Yes for "Do you print for MS-DOS programs?")
  4. The printer wizard will display a message stating that “The Network Printer is off-line”. This is OK. Continue the Add Printer Wizard until finished.
  5. When finished, go to Control Panel-Printers. The printer icon will be grayed out indicating the printer is not ready.
  6. Right-click the Printer, and select Properties. Then select the Details tab, as shown below.
  7. Click the Add Port button. On the resulting screen, select Other, then Shared Port, as the port to add, as shown below.
  8. Click OK to see the Print Port Configuration screen, as shown below.
  9. Click the Browse Device button, select the desired Multi-function LevelOne Wireless Broadband Router, and click OK.
  10. Click OK to return to the Printers folders, and right-click on the Printer. Ensure that the Work off-line option is NOT checked.

The Printer should no longer be grayed out, and is ready for use.
Problem 3:
On my Macintosh, I can't find the printer connected to the LevelOne Wireless Broadband Router.
Solution 3:
Check the following settings on the LevelOne Wireless Broadband Router 's Printer Port screen, accessed from the "Advanced" menu:
  • AppleTalk Zone - If the zone is set to a zone name, only computers in that zone will be able to use the printer.
  • Printer Object Type - If this is incorrect, the printer will not be visible from the Macintosh..

 

Dial-in Access

This section is available for LevelOne WBR-1100TX only.

Problem 1:
Remote PC can't connect to the LevelOne Wireless Broadband Router.
Solution 1:
Check the settings on the LevelOne Wireless Broadband Router
  • Dial-in is Enabled.
  • User has been created, and has Dial-in permission.
  • Call-back settings are correct for this user.
  • Modem settings are correct.
  • Both the LevelOne Wireless Broadband Router and the remote PC are using the same settings for the login authentication (PAP, CHAP, MSCHAP).
Check the Modem
  • Modem is properly connected and powered on.
  • The modem is working correctly, and the Remote user is dialing the correct telephone number for the modem.
    This can be checked by listening to the modem. You should hear the LevelOne Wireless Broadband Router 's modem answer the incoming call.
    • If the call is received but not answered, the modem's "Auto-answer" feature is turned OFF. To turn it on, add the appropriate AT command to the Initial String in the on the LevelOne Wireless Broadband Router 's Modem Properties screen. See Chapter 6 for details of the Modem Properties screen, and Appendix C for more information on AT commands.
    • If the call is answered, but no connection is established, then either the modems are unable to negotiate a connection, or the login to the LevelOne Wireless Broadband Router has failed.
      This can be checked by examining the Log file for the Remote PC. See Finding the current Initial String in Appendix C for instructions on enabling and viewing the Log file.
Check the Remote PC
  • Ensure that both the LevelOne Wireless Broadband Router and the remote PC are using the same settings for the login authentication (PAP, CHAP, MSCHAP).
  • When prompted for "User Name" and "Password", the remote user must enter the correct User Name and Password, as configured on the LevelOne Wireless Broadband Router 's User Details screen.
  • The modem Log file on the remote PC may provide useful information about the cause of the connection failure. See Finding the current Initial String in Appendix C for instructions on enabling and viewing the Log file.
Problem 2:
Remote PC can connect, but can't access LAN resources.
Answer 2:
Only TCP/IP - based resources are available. Microsoft networking is NOT supported. To gain access to your PC on the LAN, you need to install and use a "Remote Control" program like PC Anywhere.
Problem 3:
On the LAN, there is an IP Address conflict involving the Dial-in PC. How do I set the IP Address allocated to the Dial-in PC?
Answer 3:
This problem can only occur if the LevelOne Wireless Broadband Router 's DHCP Server is Disabled.
In this situation, the DHCP Server must still allocate an IP Address to the Dial-in user. To set this IP Address:
  1. Connect to the LevelOne Wireless Broadband Router
  2. On the LAN screen, locate the DHCP Server section, and set both the Start IP Address and the Finish IP Address to the IP Address you wish to be assigned to the Dial-in user.
  3. Save these settings.
