FAQ: 1. I can’t receive fax? BitWare, WinFax, and the Fax software that’s from Windows are supported by the modem. Eastfax may be unable to be supported by the Conexant modem esp. for receiving fax. Besides, all modems don’t support receiving or sending faxes while PC is turned off. 2. My windows7 can’t find the modem? The modem supports windows7 32bit and 64bit perfectly. Most windows7 OS can recognize the modem and install its driver automatically. However some compressing edition of windows7 can’t do it. Then you need to install the driver from its CD drive. 3. How do I check whether the modem driver is correctly installed and working properly? 1). Go to Modem inside the Control Panel and check if there is any modem listed. Then click on the Diagnostics tab, highlight the com port where the modem is set and click on More Info. You should see a set of commands and responses listed. 2). Try to connect to an ISP. 4. My modem doesn't connect or stay connected at 56K? Sometimes the phone line conditions are unable to support V90 connections and consequently are unable to operate at 56k. Your modem will perform better if you make a V34 connection instead. To accomplish this, the modem must be given the at+ms=v34 command. This can be done in a HyperTerminal session or added to the modem initialization (init) string. Please see the help files for your respective operating system for more information. 4. When I try to access my modem I get a blue screen? First try to re-install the drivers. If the modem still doesn't work try updating the drivers. If the problem only recently started happening try removing any new hardware or software that was recently installed. 5. I am having problems connecting or my modem keeps on disconnecting. This can sometimes be caused by other equipment that is connected to the same telephone line, by using a surge protection device on the telephone line or by faulty telephone wiring/cords. Try the following to see if it resolves your problem. ●Disconnect all other equipment from the telephone line, especially cordless phones and answering machines. ● Try connecting the modem to a different telephone outlet to see if the wiring is at fault. (Temporarily move the computer - do not use a long extension cord). ●Connect the modem to the telephone outlet directly using the telephone cord supplied with the modem/computer, do not connect via any surge protection device extension cords or adaptors. 5. I can't receive fax sometimes? One reason may be that there is something wrong with the RJ11port of the modem. The metal spring may be oxidized. Can you use an eraser to clean the spring and try the modem once more?
