Read more: A wideband modem is a modem that uses multiple analog phone bandwidths to transmit data signals. In a multi-channel carrier system, the nominal bandwidth of an analog** channel is 4kHz, and the 12 channels are combined to form a base group with a bandwidth of 48 kHz (60 108 kHz), the 5 base groups or 60 channels are combined to form a supergroup with a bandwidth of 240 kHz (312 552 kHz), and the 5 supergroups are combined to form a 300 main group with a bandwidth of 1 232 kHz (812 2 044 kHz). Depending on the frequency band occupied by the wideband modem, there are base group modems, supergroup modems, and master group modems.

Wideband modems are mainly used in places where computers and computers, where multiplexing low- and medium-speed data is used for high-speed data, digital security** and file faxing. With the construction and development of digital networks, the use of digital channels to transmit high-speed data is also increasing, which is economical, convenient and reliable. As a result, the demand for wideband modems is not urgent, and there is no significant progress in research and development.

Hello, do you want to consult about the router or the cat? Please describe your question in detail, otherwise there is no way to answer it for you.

Investigate the problem with your router or broadband modem Diagnosis is just a procedure that is performed, not a person who can see if you have a router or not, he can only diagnose a general direction. If you don't have a router, you need to create a new broadband connection and enter the broadband account and password to connect.

It may be that your router is not set up, you can log in to the IP of the router to see if there is network data on the router, if there is, it means that there is a problem with your cat.

Is the network you opened desktop?

You give your refresh into a notebook on it.

Or maybe your router isn't set up.

You try creating a new one and see if the NIC is running.

You turn off the laptop's Wi-Fi card, then plug it in and wait a while.

Do you try to reinstall the wireless card program?

It could be a router limitation.

If you only use this broadband route, you can't use it directly as wifi, not that you can use wifi to access the Internet if you enter the password on the back of it, you have to handle it.

Is there a router? If there is, then reset the router and try again. If you just use a switch, you can't use multiple computers at the same time.

Just change the IP address in the IP protocol to auto-fill, and the steps don't need to be explained.

Manually set a fixed IP and a fixed DN server to try.
