Star Rush - one of the biggest rogue software launched by China Telecom itself! **Carry! ）

If you pretend to be you, cry.

After logging in to the Internet, Starry Sky will automatically send the host network card address to the server, and the server will mark that you have used the "Star Express" dial-up, once the mark is successful, no matter what dial-up software or router you use in the future, it will not be able to dial through, and the password will be incorrect, even if the system is reinstalled.

Many people are using routers for ADSL dial-up, so that several machines can use routes to happily share the Internet, and the ADSL virtual dial-up of telecom is PPPoE protocol, which cannot be changed by telecommunications, therefore, it is difficult for telecom to restrict everyone from sharing the Internet.

Telecom tried to block the router many times without success, at the beginning there were network pioneers, equivalent to a telecom network scanning software, constantly impacting some ports on the router, resulting in the route can not work normally, but this software has caused a large number of network blockages, under the premise that the capacity of the telecom line is not expanded, it is a very dangerous software, the victim may be telecom itself first, at the same time, the current router through the firmware upgrade, is no longer afraid of the scan of the pioneers, the first attack failed.

Recently, Telecom invented a dial-up server, called "Starry Sky Speed", the electrical signal said that this software can improve the speed of Internet access, 512K ADSL directly upgraded to1M, 1M upgrade to, someone in Xi'an has tried, there is no speed up at all, and Telecom has not advertised it as such, Telecom is to send people to install this software for users door-to-door, and the only result after installation is that you may not be able to use the router to dial.

Check two sides:

1. The IP address and DNS server address of the local connection need to be obtained automatically.

Step 1: Right-click the "Network" icon on the desktop and click "Properties".

Step 2: Click "Manage Network Connection" at the pop-up window;

Step 3: Double-click "Local Connection" to display the properties;

2. If you can't access the Internet after setting the automatic IP address, you need to use software to repair the network.

1. Open PC Manager and select Toolbox.

2. Select Network Repair.

3. Click Repair.

1. First of all, determine whether a single computer cannot access the Internet or all computers in the LAN cannot access the Internet. If a single computer cannot access the Internet, in the Windows XP 2000 operating system, click Start All Programs Accessories Communication Network connection command to open the Network Connection window (you can also right-click the Internet neighbor icon and select the Properties command).

2. Then check the status of "Local Connection". If the icon of the local connection is two small computers flashing and prompting "connected", it means that the line from the switch hub to the computer is normal, the network card can basically work normally, and the inability to access the Internet is caused by improper operating system settings or software restrictions. Use the ping command to ping the remote host to see if it can be pinged, if it can be pinged, it means that the network connection is normal, and then check the firewall settings and server settings in the computer.

3. If the ping does not work, it may be a network protocol configuration problem. Check the configuration of the computer's IP address, gateway, DNS, etc.

4. If the local connection icon in the "Network Connection" window is gray, it means that the local connection (network card) is disabled, then you only need to double-click the local connection icon to re-enable it.

5. If the local connection icon in the "Network Connection" window prompts "local cable is unplugged", it means that one end of the network cable connector from the switch or hub to the user's network card is loose or there is a problem with the network cable, then check whether the network cable is in good contact, and then check the network cable if the contact is good.

Disconnect so reconnect.

If it is a computer system problem, check it with ADSL dialing software.

The network cable you use is the same as **.
