Therefore, as an option, try to temporarily disable anti-virus and / or firewall and see the reaction of the network.If the Internet is to work, then it was really in these programs.If not, then turn it back, because the source of the problem is something else.

router or laptop?

To determine the source of the problem, connect the router to another device - the tablet, stationary PC, smartphone.If other gadgets gain access to the Internet (websites load), then the problem is in the laptop.If the Wi-Fi network is detected, but the actual connection is missing, something is wrong with the network settings.
