The Internet disappears, but not a connection with the router

We installed a router in the dormitory. On weekends, when there are few people, the internet works fine. As soon as there are a lot of users, there are constant failures. A yellow triangle appears and the Internet disappears, although the connection to the router is stable. On other laptops everything is normal.

New drivers put new, IPv4 has automatic ip. There is no access to the router.

Answer:

At first glance, the problem is common and understandable. Routers very often can’t withstand the load, which is created on them by connected devices, and simply “fall down”. As you wrote, the connection to the router is there, but there is no Internet. Because of the load, the router loses connection to the Internet, and as a rule, everything starts working again only after rebooting the router.

You have the same situation, the internet is lost when there are many users who connect to the router. And this is logical. But you write that on other laptops everything works fine, but the problem is only with you. I don’t know why this is so. Yes, and I think that it can not be so, and problems with the Internet appear in everyone.

If you even think logically, it is clear that the problem is not in the laptop. After all, as long as there is no load on the router, then everything works. And since there is no access to the router, and I understand it is not yours, it is unlikely to do anything.
