Cant Ping cisco ap in ROM Mode

Hey, I am trying to change the IOS of a cisco access point, but I until now without any success.

I tried to config my access point in this way"first I formated the flash to remove the ios":

ap: set IP_ADDR 192.168.100.100                                                 

ap: set NETMASK 255.255.255.0                                                   

ap: set DEFAULT_ROUTER 192.160.100.1                                            

ap: tftp_init                                                                   

ap: ether_init 

and my computer with the ip 192.168.100.1 and GW 192.168.100.100, but I cant ping from my pc to the access point.

I disabled the firewall to test, but the result is the same I cant ping .

sudo systemctl stop ufw.service

sudo ufw disable

I also checked the route in my pc, but looks ok:

"192.168.100.0 0.0.0.0255.255.255.0 U 100 0 0 enxc4411e752c4e"

Any ideia what I should try ? i dont have any antivirus... it is really strange.

thank you for your time.
