This has helped me a lot. I had reported an issue (#126346) that I noticed the connection dropping out when I ran experiments over WiFi. Upon touching the nano ran extremely hot, so I suspected an overheating issue.
state today (08/06/2020 - that’s EU format, not american), turning off the power saver mode at least keeps the pings at a constant pace (~1ms) so it apparently helps with that. I will run my ROS experiments and report if they have been affected by the connection.
Thanks for the hint behnam!
