Q: Why is the computer not connected to the Internet (using a router in a dormitory)

 

 

Hello everyone.

 

My friend just brought a computer this semester. However, it's almost a semester, and they never go online. Their dormitory is a router, and other people can access the Internet. That's why she can't, and the system has done it again. Now she bought the computer and repaired it. After she came back, the network connection showed that it was normal, but it was just not accessible to the Internet. QQ cannot be above.
The following methods have also been tried. Let's see why.
1. I asked her to set the IP address to a manual IP address, 192.168.1.108 (ensure it does not conflict with other IP addresses). The default gateway is 192.168.1.1 DNS: 222.172.200.68 Standby: 61.166.150.123 fill in her IP address and MAC address in the static IP address of the router with other computers that can access the Internet. But not above.
2. If you select automatic retrieval, the computer in the lower right corner will disappear. You still cannot access the Internet.

It is to use a router in the dormitory to divert the Internet, tpllink router, the above settings are set according to the instructions, DHCP those things have not moved. It should be okay.

The network adapter is normal, the system has just been done, the network cable is normal, and the router is newly bought.

The DNS is the same as theirs. The most strange thing is that the client list on the router interface has her IP address ......
When I log on to QQ, the default gateway is incorrect and the web page cannot be opened.
There is a very important clue: There is no DHCP in the local connection property, and we all have DHCP and its address. On QQ, the default gateway is incorrect.
The DHCP and other services in her computer system services have been enabled, but the Internet is still unavailable.
Moreover, it is very important that the local connection only sends information, but does not receive the information ???

 

 

Please give me some advice. Is it a virus? But where can I try to access the Internet... They won't be able to access the Internet when they get to their dormitory. Thank you for your help.
