What should I do if the win8 system cannot connect to the network?

Network (Ethernet) cable 2. Check to make sure that the DSL filter is not used between the telephone jack and the modem. 3. Check the indicator light on the modem. These lights can sometimes indicate the location of the problem — Ethernet, DSL, cable, fiber optic connections, or modem power. 4. Reset your IP address. Here's how to do it: a. Open the “Command Prompt” by: swiping from the right edge of the screen to the middle, click "Search” (If you use the mouse, point to the top right corner of the screen, then point the pointer Move down, click “search”), type a command prompt in the search box, and then click or click "application” and “command prompt”. b. At the command prompt, type ipconfig /release and press Enter. This will release the current IP address. c. At the command prompt, type ipconfig /renew and press Enter to get the new IP address. This will renew the DHCP configuration for all adapters. To renew the IP address of a specific adapter, enter the name of the adapter that you displayed when you entered ipconfig at the command prompt. 5. Winsock file corruption can cause connection problems. Winsock is an application programming interface (API) standard for software that allows Windows to use network protocols such as TCP/IP. For more information, go to the How to Determine if Winsock2 is corrupted and recover from corruption on the Microsoft website. 6. Ask your Internet Service Provider (ISP) to verify that their servers are working properly and that you have access to ISP user accounts and ISP services. 7. If you have recently changed your router or modem and your ISP is using MAC address filtering, your ISP will need to add your new device to the list of devices that can connect to the network. If you suspect this is the case, please contact your ISP for assistance. My connection is listed as "Restricted" This means that the computer has successfully connected to the router, but the computer is not assigned a valid IP address and therefore cannot actually access the Internet. This may also indicate that a valid IP address has been assigned, but the computer does not have an Internet connection. If you are connected to a home network, try rebooting the router. If you are connected to a domain or public network, contact the technical support for that network. I can't connect to the Internet via a dial-up connection, or the connection is broken Make sure the dialed number is correct, including any required access numbers (for example, 9), and the number is not busy. Make sure the phone jack is working properly. To test this, connect to the phone to check for a dial tone. Be sure to plug the phone cord into the modem's <line” jack instead of the <telephone” jack. Make sure the phone line is not damaged by connecting the phone to the modem's “telephone” jack. If you hear a dial tone, the phone line is normal.

If someone answers the call while you are online, your connection may have been automatically disconnected. Try connecting again. Most dial-up modems can only use analog phone lines. Verify that an analog phone line is installed, or if a digital phone line is installed, verify that your computer has a digital modem. Make sure the modem is working properly. For more information, check the information that came with your modem or go to the manufacturer's website. Contact the telephone company to verify the quality of the telephone line. If your computer has two network connections, the networking software must choose which connection to use for network communication. Networking software will choose the best performing connection. For example, if connection A has an Internet connection but is slow and has poor performance, connection B does not have an Internet connection but the local network performs well, the networking software will route network traffic through connection B. This means you can't browse the site, so Windows will report only local connections (no Internet connection).

With the Win8 system, why can't I connect to the Internet? In most cases, the Internet connection problem is caused by a broken cable or the router and modem are not working properly. First, try running the network troubleshooter to see if it can diagnose and solve the problem

With Win8 system, why can't I connect to the Internet? In most cases, the Internet connection problem is caused by a broken cable or the router and modem are not working properly. First, try running “Network Troubleshooter to see if it can diagnose and resolve the issue. Open “Network” Troubleshooting: Swipe in from the right edge of the screen and click "Search" (If you use the mouse, point to the top right corner of the screen, then move the pointer down and click “Search”), enter the network troubleshooting in the search box, then click or click “Set” and <; Identify and fix network issues”. Here's another way to open “Network Troubleshooter. Swipe in from the right edge of the screen (if you are using a mouse, point to the top right corner of the screen, then move the mouse pointer down), and then tap or click "Search”. Enter your network troubleshooting in the search box, then click or click “Set” and <; Identify and fix network issues”. If running a network troubleshooter does not resolve the issue, follow these steps: Make sure that all cables are connected (for example, make sure the modem is connected directly or through a router to a valid telephone jack or cable connector). Unplug the power cord from the modem and router. On the back of the router, indicate the location of the power cord

After all the LEDs on the device are off, wait at least 10 seconds, then reconnect the power to the modem and router. Some modems have a backup battery to prevent the light from going out. For this type of modem, you can press and release the reset button quickly. If you do not see the reset button, remove the battery. If you are setting up a new computer for the first time, check to see if your router is fully compatible with Windows. Due to the new networking features in Windows, some older network routers are not fully compatible and can cause problems. To see a list of routers that are compatible with Windows 8 and Windows RT, visit the Compatibility Center on the Windows website. I can't connect to the Internet via a broadband connection (DSL, cable or fiber). 1. Check that the network (Ethernet) cable is properly plugged into the modem and the Ethernet port on your computer.
