Slow Adhoc(IBSS) Mode!

Hi everyone ,
I am using jetson nano and intel ac 8265 intel wifi module.I want to use this module in ibss(adhoc)mode.
For this ,I configured this file(/etc/network/interfaces) as follows

auto wlan0
iface wlan0 inet static
address “ip”
netmask “netmask”
wireless-channel 1
wireless-essid “ssid”
wireless-mode ad-hoc

I set the ip addresses on the two devicess to be different.I get too much delay when I ping the other device.
I don’t have this issue in other wifi modes.For managed mode I changed the power management setting to off but ı can not do it this setting for adhoc mode.
What could be the cause of the issue or how can I solve it?
