Troubleshooting the Modem
Please read t e following Q&A to elp debugging t e problems wit your ADI ADSL USB modem.
USB driver is not re-loaded after unplug and plug back the USB cable to modem.
C eck “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 c eck on board LED status. Provided DSLAM is ready for operation, LED D6 s ould
be “blinking” (default setting) for t e central office modem detection. Make sure line type selection matc es
wit w at DSLAM supports.
hich OS works the best?
Bot Windows 98 and Windows 98 2nd Edition are supported. Windows 98 2nd Edition supports USB bus
power management and Native ATM functions, t erefore 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 sc edules.
How do I know if ADI USB driver is installed correctly?
Open “Network Panel” from “Control Panel” folder. “ADI USB ADSL Modem” entry under t e Adapter tab
s ould exist. Click on its “Properties”, it will s ow t at USB is corr ectly installed or not. Also select
“Device Manager” menu from “System” properties of “Control Panel” to c eck t e existence of USB driver
from “Network adapters”.
Is my modem trained correctly?
LED D6 s ould remain “ON” w en t e modem is correctly linke d to t e central office modem. T e blinking
rate of LED D9 indicates ow frequent CRC errors occur in t e ADSL modem. Excessive CRCs will cause
rate reduction in data flow.
Is the line passing data?
To determine if data flow is occurring, execute t e program “Netstat.exe” (e.g. “netstat –e” to view Et ernet
statistics) from a DOS Window. If data flow is occurring, t e values given by Netstat s ould be increasing
every time it is executed.
How do I set modem IP address?
To determine t e modem IP address, execute t e program “ipconfig.exe” (e.g. “ipconfig /all”) from a DOS
Window. T e IP address is s own on t e 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
c ange IP address.
Can’t install the device driver?
If you ave 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.
- Searc and delete *ADIUSB*.*, *ADILOAD*.* and *ADILDR*.* files under all t e
subdirectories of Windows (suc as C:\Windows). T en unplug and plug back t e USB
modem, remove "ADI Modem Firmware" from System Properties->Device Manager.
- Reboot PC before new driver installation.
