Hi All,
I am trying to troubleshoot high CPU usage on an 1841. It has a five minute average (as you can see below) of 37% CPU usage, not no process has a CPU usage that high, so how can this be? An invisible process is tying up the CPU? This router typically has a sustained CPU of 4-5%, now its circa 40%.
Any ideas people can give to diagnose this would be greatly appreciated
