I just set up a laptop with unbuntu xenial and can browse the internet when connected to wifi, can ping devices that are plugged into the router but cannot ping other devices that are connected via wifi even though they can ping each other. All devices are on the same subnet and can ping each other without an issue. When I plug my computer into the router i can ping the other wifi devices fine.
This is my first time diving into the linux so apologies of this is rather basic.
Any ideas on where to start?
