Hi,
my wifi connection says, the network gateway is accessible, but windows couldn't receive network trafficfrom the internet. I'm new to pcs, I've tried a couple of things I've found online but I really don't know what I am doing. Can anyone help me solve this.

Please help…

I didn't find the right solution from the Internet.
