Computer poisoning is restricted or no connection, computer status is restricted or no connection

If there is a restoration, it will be restored, and if there is none, you have to reinstall the system, and there is no way to solve it, only to reinstall the system.

You've tried other computers, but you don't have a network cable! Also see if there's something wrong with your network card! If it's really poisoning, antivirus software won't necessarily solve the problem! Let's reload!

Go directly to safe mode, and then use the antivirus soft to poison it. If it's not poisonous, you manually change the IP address... There will be no limitations.

Restricted or unable to connect may be the expiration of the broadband can not get the lease, it should not be a Trojan virus, it is recommended that the landlord disable the network connection and then wait a few minutes before connecting to the network, if it still can't be solved, you can consider calling your network operator or making a backup and one-click recovery system.

It may be that the IP address has been changed, and it may be changed back or set to the default IPOr restart your computer.

Hello friends:

1) When the wireless network or local connection appears "restricted or no connection, there is a firewall" and a yellow exclamation mark, even if you do not connect to the Internet, it is very likely that it is: IP error, router packet blocking, IP restriction and other faults, you can use the following methods to try it, maybe it is a good solution:

2) Handling method:

First of all, it is recommended that you use the 360 network repair function (360 network disconnection first aid kit) or the "network repair" function in the QQ butler toolbox to see if it can be normal, and then use the following solution:

1) The first plan: there is a more practical way to deal with it: XP system:

It is to find the online neighbor of the desktop, click the right-click property, and then find the local connection, right-click, there is a deactivation at the top, you click to deactivate, and then after five seconds, then click to enable, generally this is solved, and then restart the computer, your computer can go online, win7 system: click on the desktop: network right-click properties device manager network adapter select the wired network card or wireless network card you want to choose After selecting the network card, right-click and click "Disable" in the right-click menu After five seconds, click Enable in the right-click menu, The general network can be used.

2) The second plan: first of all, the data of the wireless router must be cleared, which is to press the restart twist on the wireless router, so that the wireless router will be restored to factory value, and then use a smart phone or a computer (whether it is a desktop or a notebook), and then enter in the address bar of the browser: or, the network segment is different, the input is different, and the label behind the wireless router is the main, but the former is the majority.

Then a dialog box will pop up, on this box you are asked to enter the username and password, the general username and password are admin, (this wireless router is also marked above), the modern wireless router in this step is to ask you to set a password, and then enter the router settings interface, find the Internet settings or interface settings, according to the setup wizard, select the PPPoe method, and then enter your Internet access and Internet password, Then set the wireless parameters WPA2 mode and wifi password in the wireless network settings, and finally click Save, so that the wireless router will automatically restart, which means that the setting is successful, and you can access the Internet.

The third solution is: because the router sets the IP limit, and your own computer also wants to IP Internet access, although connected to the wireless network, or plugged in the network cable, but your IP is within the limit, it will also lead to "restricted or no connection" and can not access the Internet, which has to enter the router to set up, and the IP can be solved by adding the IP into it.

Hope it helps you and I wish you happiness

That's when the system is down, and the only and best option is to reinstall the system.
