The commands that worked for my RT-AC68U and RT-AC3100
  • CPU temperature: cat /proc/dmu/temperature
  • Radio 1: wl -i eth1 phy_tempsense
  • Radio 2: wl -i eth2 phy_tempsense
are not working for the RT-AC86U. Anyone know the new commands for the RT-AC86U?
 
Different SDK/BSP from the earlier devices.

One can dig around /sys/class/thermal

see what shows up.
 
For the CPU, you need to have a recent enough firmware that has the bcm_thermal kernel module (it wasn't included in earlier firmware releases).. It will be available in /sys/class/thermal/thermal_zone0/temp .

For wifi, I only know how to query it through the API, no idea if it's available from userspace using wl or dhd, sorry.

Thanks. Its a passing curiosity at this point, so I'm not going to try to dig further for now. Maybe you'll eventually add it to your firmware?

It's already there, on the Tools -> Sysinfo page.
 
My 86U values are:
Temperatures 2.4 GHz: 52°C - 5 GHz: 57°C - CPU: 75°C
The ambient temperature is 68°F and there is minimal load on the router.

Hi, can you tell me is there a error for usb hub in the initial log like this:

kernel: ++++ Powering up USB blocks
Feb 14 02:00:17 kernel: usb3 reseting..........
Feb 14 02:00:17 kernel: release usb3 reseting..........
Feb 14 02:00:17 kernel: hub 1-0:1.0: config failed, hub doesn't have any ports! (err -19)
Feb 14 02:00:17 kernel: usb3 reseting..........

When I reboot my router and I see this error at the beginnng.. can you check is it the same in your log?

Thanks for help...

This is above my pay grade. Someone else will have to assist you with this.
