Anyone else seeing this? Since upgrading from 6.1 to 6.3 my idle box went from 99.5% idle to 97.5 to 98%… with 1.5 to 2.0% now being used by “ethernet”. Anyone seeing this also?
Try disabling the LCD. Also when you say idle, is the unit connected to a cable or DSL modem? Those things are anything but idle, they constantly send packets to your WAN interface.
LCD is disabled. It is connected with no traffic. I suppose even if there was traffic why would the usage change from 0% to 2.0% by just upgrading from 6.1 to 6.3?
It could be services … DHCP for example or bridge ports. Anything else that expects the port to be up and running. If you’re up for testing try turning off just about everything … here is the config I use. By the way I have not unplugged my unit to see if I’m having the same usage as you.
Turn off bridge ports along with all of these
