No internet despite Wi-Fi connection?

Can't open websites on the laptop. I always have to connect to the Wi-Fi first, but it takes forever. If I have patience and wait 5 minutes, then it says connected. Still have no internet. If I then wait 1 minute, then there's no Internet, secured. I enter the router settings via http://xxx.x.x.xx, because it shows me that I'm not connected. Troubleshooting says everything would be OK, network already reset, no effect. What should I do? Lg

Router reset?

Would reset the router and test it again.

Have you restarted the router? Time to see if the cable to the router is still properly seated in the socket and in the router (maybe it has come loose)?

Which router is it and which lamps light up on the router?

Yes, I also opened the splitter and plugged in and unplugged the cable. The lamps are as always. I come in with other devices as normal…

Have you ever restarted the laptop (really choose restart and not just shutdown)? Does the laptop come online if you connect it to the router using a LAN cable?

That makes no sense to use a Lan cable. 1. Is the Wi-Fi so far away that I would need a 10 m cable, which I don't have and don't want to have? And even if it would work with Lan, it doesn't help me, I want to be able to use it wirelessly. I can't put the modem anywhere else because it is a very special power connector that is only found once in the house. The laptop was already restarted and shut down, etc. Now I'm trying to go back to yesterday's restore point. Coincidentally, made one yesterday. Everything was still going on. Lg and thanks for the answer

Yes, but I come in with other devices, so unnecessary

Brings me nothing because the other devices come in
