Troubleshooting the Modem
Please read the following Q&A to help debugging the problems with your ADI ADSL USB modem.
USB driver is not re-loaded after unplug and plug back the USB cable to modem.
Check “Device Manager” from “System Properties”, delete unknown USB device(s) if any.
After followed driver installation procedures, modem is still not working.
One obvious way is to check on board LED status. Provided DSLAM is ready for operation, LED D6 should
be “blinking” (default setting) for the central office modem detection. Make sure line type selection matches
with what DSLAM supports.
Which OS works the best?
Both Windows 98 and Windows 98 2
nd
Edition are supported. Windows 98 2
nd
Edition supports USB bus
power management and Native ATM functions, therefore it is recommended to use. Most versions of
Windows 95 and Windows NT do not support USB. Windows Millennium and Windows 2000 will be fully
supported in future software releases. Consult your local ADI representatives for release schedules.
How do I know if ADI USB driver is installed correctly?
Open “Network Panel” from “Control Panel” folder. “ADI USB ADSL Modem” entry under the Adapter tab
should exist. Click on its “Properties”, it will show that USB is corr ectly installed or not. Also select
“Device Manager” menu from “System” properties of “Control Panel” to check the existence of USB driver
from “Network adapters”.
Is my modem trained correctly?
LED D6 should remain “ON” when the modem is correctly linke d to the central office modem. The blinking
rate of LED D9 indicates how frequent CRC errors occur in the ADSL modem. Excessive CRCs will cause
rate reduction in data flow.
Is the line passing data?
To determine if data flow is occurring, execute the program “Netstat.exe” (e.g. “netstat –e” to view Ethernet
statistics) from a DOS Window. If data flow is occurring, the values given by Netstat should be increasing
every time it is executed.
How do I set modem IP address?
To determine the modem IP address, execute the program “ipconfig.exe” (e.g. “ipconfig /all”) from a DOS
Window. The IP address is shown on the line “IP Address”. For example: IP Address . . . . . . . . . : 196.168.0.2
Consult your network administrator or service provider to determine if it is valid or not. IP address is set in
“Network Panel” from “Control Panel” folder. Double click on “TCP/IP ->ADI USB ADSL Modem” to
change IP address.
Can’t install the device driver?
If you have installed previous release versions of device driver, ext ra uninstall steps are required:
- Remove "ADI USB ADSL Modem" and "ADI USB ADSL Loader" from Control Panel->Network
Properties.
-
Search and delete *ADIUSB*.*, *ADILOAD*.* and *ADILDR*.* files under all the
subdirectories of Windows (such as C:\Windows). Then unplug and plug back the USB
modem, remove "ADI Modem Firmware" from System Properties->Device Manager.
- Reboot PC before new driver installation.
