When I was in college, the route of our dormitory was often rubbed, and finally I found it out through records.

If you need to delete records, you must enter the router. You can enter 192. 168. 1 or192.168.0.1in the browser.

Regular accounts and passwords are the default administrators or guests. You can search the default password of that brand's routing on the Internet and give it a try. It should be possible to enter, and the records can be cleared after entering.
