Win7 64-bit pure version broadband connection often causes errors and solutions steps

Win7 64-bit Pure Edition Broadband connection often causes errors and resolution steps: Broadband is not strictly defined. From a general point of view, it is able to meet the bandwidth required by people to feel the various media transmission on the network, so it is also a dynamic, development concept.

The traditional telephone line system uses the low frequency part of the copper wire (under 4 kHz). ADSL uses DMT (Discrete Multi-Audio) technology to divide the original telephone line okHz to 1.1MHz frequency band into 256 sub-bands with a bandwidth of 4.3khz. Among them, the band below 4khz is used to transmit POTS (traditional telephone service), the frequency band of 20KhZ to 138KhZ is used to transmit uplink signals, and the frequency band of 138KhZ to 1.1MHZ is used to transmit downlink signals. The DMT technique can adjust the number of bits modulated on each channel according to the condition of the line in order to make full use of the line. In general, the larger the signal-to-noise ratio of a subchannel, the more bits are modulated on the channel, and if the signal-to-noise ratio of a subchannel is poor, it is discarded. ADSL can achieve data transmission rate of 640kbps upstream and 8Mbps downlink. Win7 64-bit pure version of users who use the broadband connection dial-up Internet access, if you want to access the Internet, you must first make a broadband connection to be able to access the Internet. However, when users have recently connected to the broadband, the prompt "Error 797: Not established to the remote access server. The coalition forces, because the modulation regulator can not be found. But the cat's indicator light shows normal, how is it going, the following small series to share with you the reason and solution for the deep Win7 64-bit pure version broadband connection error 797.

First, the cause analysis:

797 error is generally the computer adsl moden connection device is not found to cause the connection can not be connected, resulting in a network card and adsl modem connection failure, in the creation of connection dialing At the time, an incorrect connection was created.

Second, the solution:

1, first check the computer and cat's power and power cable. Check the properties of the network and the protocols related to raspppoe are installed correctly, and bind them to the relevant protocols.

2. When detecting the exclamation point or question mark on the NIC driver, set it to enable and check the properties of the dial-up connection.

3, check whether the connected device uses an isdn channel-adapter name (xx) device, if it is, the device is empty, all will not be connected to the network error 797. You can cancel your device and use the correct pppoe device to recreate it, or you can recreate the dial-up connection.

4, if there is a problem with the TCP/IP protocol, if there is a backup, you can restore it, or reinstall the relevant protocol, if the problem is still unresolved, you can only do the system.
