There may be many reasons for the problem that the Win7 computer is connected to WiFi but cannot access the Internet.Here are some common solutions:
1. Check the network settings: Make sure the network settings of the computer are correct.Right click the network icon on the taskbar, select "Open Network and Sharing Center", and then click "Change Adapter Settings" to check whether the wireless network card is enabled and confirm that it is connected to the correct WiFi network.
2. Restart the router and computer: sometimes the router or computer fails, just restart them to solve the problem.Turn off and disconnect the router, wait a few minutes, then turn it on again, and then restart the computer.
3. Update driver: If the wireless card driver is expired or damaged, it may cause connection problems.Find the wireless network card in Device Manager and try to update its driver.
4. Check the firewall and security software: The firewall or security software may prevent the computer from accessing the Internet.Temporarily disable these software, and then try reconnecting to WiFi to see if you can access the Internet.
5. Clear DNS cache: Open a command prompt window (press Win+R and enter "cmd" in the pop-up window), enter the following command and press Enter: ipconfig /flushdns This will clear the DNS cache of the computer and sometimes can solve connection problems.
6. Reset network settings: Open a command prompt window, enter the following command and press Enter: netsh winsock reset netsh int ip reset This will reset the network settings and may fix the problem of not being able to access the Internet.
If none of the above methods works, you may need to further check your computer hardware or contact your network service provider for help.
Since the router itself has an IP address, the default address is 192.168.1.1.If there is a possible conflict between two routes, you need to go to Route 2 to set the address of Route 2 to 192.168.0.1 (check the LAN interface settings in the network parameters), as long as it is not the same as Route 1.Then select "Disable" the DHCP server of Route 2, save it, and then Route 2 will restart.Remember, please turn off the DHCP function of the wireless router to prevent unexpected failures.
Modify the IP addresses of all computers connected to the wireless router. The IP address is 192.168.0. * (* is any number of 2-255). The subnet mask is 255.255.255.0, and the gateway is 192.168.0.1. The preferred and alternative DNS server addresses are found in the running status of the wired router.
Log in to the wireless router (enter 192.168.0.1 in the IE address bar), and select the WAN port connection type of the network parameters as "Dynamic IP".The wireless router will restart automatically after setting.
To view or modify the wired router, enter 192.168.1.1 in the IE address column, and to view or modify the wireless router, enter 192.168.0.1 in the IE address column.Wireless routers are also available.In this way, the function of wired router+wireless router is realized without any conflict.Of course, if the wireless function is not enabled, you need to use the cable to open the wireless signal channel.To use wireless properly.
The following methods cannot be tried online: 1: Look at the laptop. There is no common wifi shortcut key Ctrl+F5 2: If the connected network cable is on, check whether the connection to the computer is on. If it is on, it indicates that it is running normally. 3: Right click Network Neighborhood or Network Properties Network Connection to see if the network is disabled. 4: Try restarting the computer 5: Check whether the corridor power supply system can supply power normally (because the corridor power supply is generally network power supply) 6: Call Telecom and ask if your account number is normal 7: The mobile phone cannot access the Internet to see if the wifi is working properly. Check carefully whether the password you enter is the same as the router password. 8: The mobile phone cannot be connected to the mobile network. You can call the telecom company to ask about the situation, or restart the mobile phone to try. Don't forget the simplest thing is to open the mobile data.
