SSH takes a while to display the command prompt (noticeably slow)

sudo iwconfig wlan0 power off

#3

that will shut off wireless, right? What if I wish to use WiFi & BLE along with ethernet?

anyway, I checked the same & no luck!

sudo iwconfig wlan0 power off
[sudo] password for rock:
Error for wireless request “Set Power Management” (8B2C) :
SET failed on device wlan0 ; Operation not permitted.

it throws an error, but the radio is turned off. I even checked it with nmcli, but no luck either

sudo nmcli radio wifi off

the delay still prevails

#4

Just turn off the power-saving mode.

We’ll have a look tomorrow.

Hi nccchirag, try

sudo iwconfig p2p0 power off

or

sudo iwconfig wlan0 power off

#6

Sorry no luck for either! it takes around 7sec for command prompt to be active on Putty via SSH

sudo iwconfig wlan0 power off
Error for wireless request “Set Power Management” (8B2C) :
SET failed on device wlan0 ; Operation not permitted.

rock@rockpis:~$ sudo iwconfig p2p0 power off
Error for wireless request “Set Power Management” (8B2C) :
SET failed on device p2p0 ; Operation not permitted.

I also tried instructions mentioned here, but no luck :frowning:

thank you
