Wi-Fi network disappears when connecting a laptop (strange problem)

The situation is as follows. When connecting a newly purchased laptop to the home Wi-Fi network, the whole network in 2-7 minutes becomes with Limited Access and does not work. While on a stationary computer everything works. If the same laptop is connected to another network or to the mobile Internet via an access point, everything works fine.
What is very strange is that this network and router have been working for about a year with these settings and nothing has ever broken as it is now. I have 3 devices stably connected to it via wifi and never had any problems.

Stalemate situation, please advise what to do. Thanks.

Answer:

The problem is indeed very strange. Have already written about this problem in the comments more than once. And, not necessarily the laptop can “put” the whole Wi-Fi network, after connecting. Smartphones and tablets also cope with this perfectly well.

I don’t know the solution to this problem. I can’t even guess what can cause the Internet to disappear after connecting a laptop.

What I would try to do: write a static IP address in the properties of the wireless connection on the laptop. If the router has an address like 192.168.1.1.1, you can write 192.168.1.150. Or better yet, reserve a separate address for the MAC address of the laptop in the router settings. It is very strange why this problem is only with your network. You have not configured anything extra? Just connected a new laptop and the Wi-Fi network stopped giving out internet?
