It is recommended to uninstall the Rising Firewall, Jiangmin Firewall, Skynet and other firewalls first, and in addition, turn off the firewall that comes with the XP system.

2. The router or server encloses the name of your computer.

This needs to be discussed with your company's network administrator why he has made you bad.

3. You have been infected with the ARP virus.

Enter the arp -a command to view it. In addition to the host IP, if there is any IP, then it is an ARP virus.

China Unicom card can WLAN has 2 modes:

1.Apply for an ordinary mobile phone card, Unicom mobile phone itself is at most on 3G (WCDMA), but with this ** number, you can get a wifi signal login account and password, whether the business hall directly gives or uses a mobile phone or computer to connect to the wireless signal after applying on the login page I don't know, and then just like ordinary WLAN Internet access to the Internet.

2.Direct wireless network card,Generally, with the card (in fact, it is still an ordinary SIM card) will be equipped with a hardware similar to a large U disk,In general, it is a Unicom wireless network card,Plug it into the computer,You can access the Internet after installing the corresponding driver。

The easiest way to do this is to find a notebook, bring it to the business hall, and ask them to let you get on the WLAN.

You look at the network and sharing center to see if there is a signal of Unicom to know,Now many of them have WLAN,Just ask the service 10010 staff to know,Of course,What you buy,People must sell it to you first。 This is equivalent to a mobile phone signal, some places are not good, some places are not.

1) If it is a problem with the broadband itself, first directly connect to the broadband network cable for testing, and if it is a broadband problem, contact the broadband customer service to solve it.

2) If it's a problem with the router, if it can be used originally, it can't be used for the time being, my own practice is to disconnect the power of the router and plug it in, and I'll take a look. In there is a factory reset, from the new strict according to the manual settings can be used, I don't understand, it is not recommended to set it at will (this is under the premise of the correct physical connection, sometimes the router is slow or failed to find the IP address, not that the router is broken).

If it can't be solved all the time, it is recommended to call the customer service of the router, they have **** guidance, I encounter a problem that I can't solve by myself, it is very useful to consult the advice they gave, and they will give the correct advice for your settings or operations.

3) If you turn off the wireless on/off grip on and on, if it is a wireless connection with software, it is normal for the software to be difficult to use and often have problems, there is no better way, use a router. In addition, it is caused by the network card driver is not or is not suitable, and whether there is a problem with the network cable interface or network cable.

4) If it is caused by a system problem, it is recommended to restore the system or reinstall it.

Use the system that comes with the system restore method:

The system comes with the system restore: "Start" "Programs" "Accessories" "System Tools" "System also knows the original friend", click "Restore my computer to an earlier time", press Next, you will see that the date page has a dark date, that is the restore point, after you select, click the next restore (win7810 restore the system, right-click on the computer to select attributes, on the right side of the selection of system protection, system restore, follow the steps to do it, if there is a restore software, the image backup that comes with it, And the backup is made, and the system can also be restored with software and image backup).

It should be a fault with the network cable.

What happens if I can't get online? Is it a desktop or a laptop? Is it wireless or wired? Or is it a mobile phone? You have to explain this clearly to solve the problem.
