How to connect win7 to China Telecom s router an exclamation point will be displayed after connecti

This kind of problem is very common for two reasons, either your computer, or the router of the telecom has been spoofed by ARP, and there are two possible attacks of ARP spoofing, one is the spoofing of the router's ARP table; The other is the spoofing of the ARP table of the intranet computer, of course, both attacks may be carried out at the same time. In any case, after the spoofing is sent, the data sent between the computer and the router may be sent to the wrong MAC address, which on the surface means "no access to the Internet", "no access to the router", "router crash".

Therefore, unless the telecom restarts the router, it will not be able to connect to the network.

It's not a problem with your system or computer, it's related to the school's network port, our dormitory is like this, but it generally doesn't affect the Internet, just use a computer connected to the route to access the Internet, just set it up, you don't need to set it up in the future, you can use it until there is no money.

Connecting to the router does not require dialing error 651 there

If it is an optical modem, it needs to be cracked before it can be connected to the wireless router and the wireless router settings.

1. First, connect the home network cable to the WAN port of the router according to the manual, and then connect the LAN port of the router with the computer with the network cable. Turn on the computer, the IP address of the computer is automatically obtained, open the Internet Explorer, enter the obtained IP address gateway in the address bar: alternatively, enter the account number and password admin (both are the same).

2. After entering the route, select the setup wizard, then select the ADSL connection mode and select PPPOE, enter your account and password at the WAN port, if it is a static IP of Telecom, select the static connection, which is generally given to the account number and password; Then save! After the router restarts, go to Routing, select Wireless Network Settings--- Turn on Wireless, Turn on Broadcast--- then Wireless Security Settings --- you select the frequency band WEP, WAP WAP2, WAP-PSK WAP2-PSKIn any of these mid-bands--- just enter your own password!

Save --- restart routes! Get!

3. Note that your window7 wireless connection must match the frequency band you choose, otherwise you won't be able to access the network even if you connect!

Win7 wireless network shows that it is connected but cannot be connected to the network, and there is a solution to a yellow exclamation mark.

Not necessarily 1 If the exclamation point is displayed, it may be that you dialed the number

2. If you can access the Internet without dialing up, in this case it is a telecommunications problem.

Limited network or no connection can be clicked into the place where x is clicked to view the full mapping, which can generally be solved.

If you don't know the account number and password of the telecommunications network.

Then I feel like I can't help the landlord.

Internet connection** when an exclamation point appears.

The problem may be with the router or modem.

That is, it is either a problem with the router, or a problem with the modem, or a problem with the computer's DNS settings.

But if you even forget your telecom account.

Then you can only call 10000 to give customer service a warranty.

First, use 360 Security Guard to diagnose the network, and then use the diagnosis results to make corresponding strategies.

The general question is as follows:

Problems with native network settings.

Gateway line setup issues.

Router issues.

Computer hardware issues.

Manchu Gege made the above judgments, I don't know if it's right, you try it, if not, find me.

Is it that the account has expired, and the exclamation mark is that the Internet is not accessible,

Can I get into the router??? Go into the router and take a look
