This article is to share with you about the reasons for the restrictions on the Internet. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Reasons for network restrictions: 1, hardware reasons lead to computer network restrictions, you can check whether the network cable and crystal head contact is bad; 2, software system reasons lead to computer network restrictions, check the status of network services.

Reasons why the network is limited:

First, the computer network is limited due to hardware reasons.

Methods:

1. Check whether the network cable and crystal head are in bad contact.

First of all, check whether the network cable is plugged in, pull out and reseat the first two ends of the network cable, or replace a new network cable.

2. Check MODEM, switches, routers and other Internet equipment

Restart MODEM, switch, router, or restore to factory state, and don't forget to turn on the DHCP option for routing, and check the router security policy settings, whether to bind MAC addresses, enable restrictions such as IP address filtering.

3. Check whether the network card device and driver are normal.

Uninstall the network card, wireless network card driver, download and install the latest version of the network card, wireless network card driver, or replace the network card test.

4. Check BIOS settings and version compatibility

Try to restore the BIOS default settings and update BIOS to the latest version.

Second, the computer network is limited because of the software system.

Methods:

1. Check the status of network services

Confirm DNS Client, DHCP Client, IP Helper, and WirelessZero

Network service status such as Configuration (default is on), and then restart the computer.

2. Check the IP address and DNS server address

Verify that the required IP address and DNS server address are entered correctly (the default is automatic acquisition). For networks that are bound with IP addresses and DNS server addresses, enter the specified IP address and DNS server address.

3. Reset network connection, proxy, DNS cache

Run the command prompt as an administrator and enter the following command:

NETSH INT IP RESET

NETSH WINHTTP RESET PROXY

IPCONFIG / FLUSHDNS

Press enter to confirm after each line is completed, and restart the computer after execution.

4. Reset Winsock

The Winsock exception results in limited network connection prompts, and you can reset Winsock using the command prompt (run as administrator):

NETSH WINSOCK RESET

After typing, press enter to confirm, restart the computer to reset the Winsock directory.

5. Check the system firewall settings and system security settings

First turn off the firewall to confirm whether it is normal, and then modify the corresponding inbound and outbound rules of the firewall. Check that the local security policy "- -" IP security policy "setting is normal.

6. Check whether the wireless network check "enable federal information processing standards for this network".

By default, the Win8/8.1 system does not check "enable federal information processing standards for this network". Some wifi users with limited Win8/8.1 connections can solve the wireless limitation of Wifi by checking this setting.

7. Check whether the system is poisoned, whether the system patches are complete, and whether the hosts file has been abnormally modified.

In Windows

Under XP, you need to install a patch to support WPA2-PSK encryption, and the abnormal modification of HOSTS files results in the website being blocked. Therefore, if the other operations mentioned above are invalid, you can consider killing the virus, upgrading the system patch, and repairing the HOSTS file.
