I have a WPA2 WiFi network at my place. My laptop has an unstable WiFi connection with the network. It randomly disconnects, and may or may not connect again. Some times it does not connect at all. Sometimes it disconnects whenever I attempt a relatively heavy download. I have linked two outputs of a diagnosis script.
Vaio running 16.04. Intel(R) Wireless WiFi 4965 driver for Linux.
How can make the connection more stable?
