My Laptop and my phone are both connected with the same Wireless lan. My Server is connected to a switch which is connected with my router.
There is a web-interface running on my server. When I start my Laptop I can access it fine, but after about 5min I lose the connection.
My phone is still able to ping the server, so the server is still running.
When I try to ping the server from my laptop it says that the destination host is unreachable. Same when I try to ping my phone or any other device in my network, except for the gateway.
My Laptop runs Linux Mint
