1. If the broadband is in arrears or expires, you need to pay or renew it in time.

If you don't have Internet access on the computer, it is common to see the following kinds of love banquets.

1. The optical modem or router crashes and the Internet cannot be accessed.

2. If there is a problem with the source configuration of the system network, the common reason for not being able to access the Internet is that there is a problem with the LSP protocol, and the IP address and DNS are not automatically obtained.

1. First of all, it is necessary to judge the way to access the Internet, not that the network is connected to the modem (modem), the switch or router can access the Internet, and it needs to be judged separately according to the connection mode.

A. Directly connect to the modem (modem), need to dial the connection to access the Internet, enter the account number and password provided by the ISP provider, dial the number with PPPoe connection, and the dialing is successful to access the Internet.

b. Switches, switches are only connected to the network tool, and cannot access the Internet.

C, router, need to check the WAN connection status of the router.

Check method (take TP-link as an example):

If the WAN port is normal, you can connect to the network, but if the WAN is not normal, you need to check whether the devices connected to the WAN port are normal. One of the most important places is whether the WAN port data packet is generated, if the connection fails, then there is no data generated. If the data refresh does not respond, it may be that the data refresh interval is not that short.

If there is data generated, the connection is normal, and if the data is refreshed after a period of time, the network connection is normal. That's the problem with the settings on your computer.

I know this question! Set the IP address, if it doesn't work, you can only redo the system.
