College】 【weak computer hardware failure Raiders 6 --- Power By 【China】 weak home network.
computer failure of the MODEM <br> ★ ★ <BR> <BR> articles a common fault: 56K of Modem not up to 56K. .<BR> <BR> This problem can be from the following considerations: <BR> <BR> 1. 56Kmodem actual maximum speed can only reach 53K or so, to consider various effects, 56Kmodem speed is generally between 45-53K. .<BR> <BR> 2. Modem telephone line to a large extent influence the transmission rate, if the phone line quality is not good, line voltage instability, 56K of the Modem to the less than 56K; another extension Internet use will also affect .Internet speed. .<BR> <BR> 3. Not installed the correct driver. .<BR> <BR> 4. And the ISP uses different protocol, only your Modem and your ISP agreement is the same, Modem 56K will meet the standards. .<BR> <BR> Exclude the above reasons, your 56KModem still much faster than 53K, this is your Modem hardware problems can be considered a replacement or repair. .<BR> <BR> Troubleshooting II: Modem disconnects often, the problem may have dropped the following reasons: <BR> <BR> 1. Phone line quality is not good; <BR> <BR> 2. If the data .Terminal Ready (DTR) over the duration of the signal void Modem default settings, it will lead to dropped calls; <BR> <BR> 3. If your phone has a "call waiting" feature of this new program-controlled telephone, whenever a call .to play in, the modem will be disturbed and disconnected; <BR> <BR> 4. In addition, Modem their quality and compatibility problems between different Modem Modem is caused by a common cause of dropped calls. .<BR> <BR> Three common faults: Modem no dial tone <BR> <BR> time when the Internet late at night when the dial tone in order not to influence others sleep, through appropriate AT command to change: you can set with ATM0 .Modem no dial tone, and ATM1 set to Modem Dial-up connection from a dial tone. .Select the volume you can change the following instructions, ATL0 (low volume), ATL1 (low volume), ATL2 (in volume), ATL3 (high volume). .<BR> <BR> Troubleshooting four: fax rate 14400 <BR> <BR> Modem reach the maximum fax rate is 14400, and send a fax rate of only 9600. .This is because most of the fax machine to send and receive rate is 9600, and only use the rate is 14400 or 33600 fax, Modem fax speed will reach 14,400. .<BR> <BR> Five common faults: Modem can not dial or connect <BR> <BR> If not properly installed on your Modem, communication will not work. .The following lists the authentication process of the communication Modem with Windows installed an incompatible driver files, could lead to COM port and Modem not working properly, it should first check if the file loads the correct Windows98. .<BR> <BR> 1. Testing existing Communications <BR> <BR> (1) the System directory and SERIAL.VXD COMM.DRV Windows95 floppy disk or CD-ROM file with the original file to compare, check the file .are the same size and period. .<BR> <BR> (2) confirm the System.ini file in the following lines: [boot] Comm.drv = Comm.drv [386enh] device =* vcd <BR> <BR> (3) in the "control .panel "run" Add New Hardware "wizard, test and install the Windows98 driver. .Note: Windows98 is not loaded in the System.ini SERIAL.VXD driver, but the use of up command to load it. .In addition, there is no System.ini in the related files with the * VCD. .These files are built in at the VMM32.VXD. .<BR> <BR> 2. <BR> <BR> Test the configuration of the modem in the "Control Panel", double-click "Modems" icon. .Verify that your modem manufacturer and model, run the "Install New Modem" Wizard detects the modem and confirm the current configuration is correct. .If your modem does not appear in the list of installed modems, clickthe "Add" and then select the appropriate modem. .If the manufacturer and the type is not correct, and not in the list of your equipment manufacturer and type, try to use "generic modem" in "with the Hayes-compatible" option, set the maximum baud rate support for the modem, and a single .Click "OK." .In the exclusion list to remove all modem entries. .<BR> <BR> 3. Check that the modem is in a state of <BR> <BR> can use the "Control Panel", double-click "System" icon, then click "Device Manager" tab, select your modem and .Click "Properties" to confirm whether the selected "device already exists, use." .<BR> <BR> 4. <BR> <BR> Check the correctness of the port in the "Control Panel", double-click "Modems" icon, select your modem, then click "Properties" in the "General" tab, .test port is listed correctly. .If not, please select the correct port, and then click "OK." .<BR> <BR> 5. Confirm the serial I / O address and IRQ settings are correct <BR> <BR> in the "Control Panel", double-click "System" icon, click the "Device Manager" tab, then click " .Port ", select a port, and then click" Properties ", click" Resources "tab displays the port's current resource settings, see the modem's manual to find the correct settings in the" Resources "dialog box, check the" Device .list "to see whether the resources used by the modem and other equipment occur if the modem and the other device, click the" Change Settings "and then click did not result in the allocation of resources. .<BR> <BR> Note: If the mouse on COM1 or other equipment, please do not use the modem on COM3. .Usually COM1 and COM3 ports use the same IRQ, and in most computers can not be used. .COM2 and COM4 have the same problem. .If possible, change the COM3 and COM4 port, IRQ settings, so they no longer. .Also, some graphics card addresses and COM4 port, and if found, use the other ports, or replace your graphics adapter. .<BR> <BR> 6. <BR> <BR> Test port settings in "Control Panel", double-click "Modems" icon, click the modem, and then click "Properties" in the menu that appears, click "Connect" .tag to check the current port settings such as baud rate, data bits, stop bits, and parity. .<BR> <BR> 7. <BR> <BR> Test the modem baud rate in the "Control Panel", double-click "Modems", select a modem, and then click "Properties", click "General" tab, and then .the baud rate is set to the correct rate. .<BR> <BR> Note: If you call the main system to set the baud rate in the original can not communicate, then reduce the baud rate can sometimes resolve the problem. .<BR> <BR>.
