Netinstall hAP ac2

RouterOS Beginner Basics
1

Hello,

I am trying to use netinstall for the first time and I’m really struggling with the procedure indicated on https://help.mikrotik.com/docs/display/ROS/Netinstall.
Maybe you could help me.

The target device is a hAP ac2 curently running RouterOS 6.49.7 Stabe (multi packages), the host from which I need to run netinstall is under linux.

What I want to achieve: downgrade this hAP ac2 to 6.48.6 (single package npk)

What I’m doing:

  • remove all cables from the hAP ac2
  • plug a cable directly from the host computer to the hAP ac2
  • turn off the hAP ac2
  • configure the host computer network device (ip 192.168.88.2, gw and dns 192.168.88.1, mask 255.255.255.0)
  • retrieved the netinstall tool on the host (wget https://download.mikrotik.com/routeros/6.49.7/netinstall-6.49.7.tar.gz)
  • extract netinstall
  • run it `netinstall-cli -a 192.168.88.3
  • plug the hAP ac2 and try to put it in etherboot state (by pressing the reset button before plugin back the power cable and keeping it pressed)

On the host computer, the last message which is displayed is “Waiting for RouterBOARD…”
My guess is that I do not succeed in putting the hAP ac2 in etherboot state…

So the stupiud question is : on what button should I press and when should I release pressing on it (tried various duraations up to 20 secs…) ? I must be really dumb not to be able to do it.

Thanks a lot in advance,

Michel.

Instead of using 192.168.88.3 you should use 192.168.88.1

I use 88.3 as well.
I even colored that bold red in my notes to make no mistake.

Keep pressing the button until you see it starts.

Are you shure that you plugged the PC into the ETH1/WAN port???

The etherboot loader just looks there!

Well… Once I turned off UFW everything (obviously) started working as expected…

Thanks for your help though :slight_smile:
