Re: 100% cpu and twitchy too

Actually, if packets are lost, CPU usage usually drops. This is true for the default LV framework, and I believe for C++ and Java too. If packets don't arrive, some parts of the system will run timed tasks, but other portions will stay asleep.

While it is possible for an excessive number of wifi networks to impact the connection to the robot, especially on 2.4 GHz, this will not cause CPU usage to rise on the robot. The charts tab will show whether the robot is losing comms, getting watchdogged, or running as prescribed. If you post a photo of the log file viewer, I can help point out the patterns.
