There is a free intranet in the community, so you can surf the Internet by plugging in a network cable at home.

Generally, a router can allocate 2~254***253 IPS at most, and ordinary routers generally allocate100 ~199 * *100 IPS by default.

Suggestion: Set an IP for the computer manually and enter your local DNS to see if it can be solved. (It is suggested to set the IP mantissa larger, such as 250~254. )

If not, there is still an IP conflict. Manually change to an available IP, then open the webpage and log in 192 168 1 or 192 168 0 1, and enter the user name and password admin. If you can log in, modify the router's LAN port settings, change the IP to 192 168 * 1, and * randomly enter a number between 2 and 254.

Don't be afraid to change the general route to the community. That must have changed the password, usually logging into the router installed by others. Besides, it doesn't matter if you switch to the IP of the main route. You can automatically acquire a new IP after your computer changes back to automatically acquire IP.

If it is determined that someone else installed the router, just remove the tick before it is enabled in DHCP settings, so that there will be no IP conflicts in the future.
