hap ac2 issue after not successful upgrade

RouterOS General
1

Hello guys!

I’ve been trying to upgrade my router from routeros v6.4 up to 7.15 (stable).
It seems that I did download wrong package ( https://download.mikrotik.com/routeros/7.15.3/routeros-7.15.3-arm.npk ) and as an instruction said uploaded this package to main Files and reboot the device.

So now it looks like that I cannot access to device through ethernet.
The network status if I’m connected to PC is - detected as 168.x.x.x and keeps disconnected and connected like each 10-20 seconds.

Tried to use reset in all ways as documentation said ( keep pushing until LED blinked, keep pushing after LED if off etc - nothing.
Netinstall also doesnt show up router’s disk to reinstall package or something.

Any ideas how to make it work again?

Thanks

Please tell me you mean a recent 6.4x.yy, not literally 6.4 from 2013?

It’s better to use one of the GUIs to do these upgrades as they will grab all relevant packages. In the case of a hAP ac², you need at least one wireless package in addition to the main OS package.

I suspect another typo. If you look again, I predict you will find 169.254.x.y instead, the IPv4 autoconfiguration IP range, meaning your client machine has no static IP, and it sees no DHCP servers.


Tried to use reset

That’s not likely to do anything more than clear your configuration and retry 7.15, but with the same broken package set mentioned above.


Netinstall also doesnt show up router’s disk to reinstall package or something.

Netinstall is tricky at the best of times. I find it simplest to use a Linux VM for this purpose rather than try to follow the official Windows-based docs.

If you follow that guide, remember to send both the routeros-.npk and the relevant wireless package, together. I’m left guessing wifi-qcom-ac-.npk given your lack of details of your original configuration.

Thanks for your reply!

I actually don’t remember exactly which version does hap ac2 has by default ( I bought it couple of years ago and didn’t use ).

So I think it should be 6.48.1 .

Tried to set static 192.168.88.21 to PC and .88.31 to Netinstall ip’s, but it looks like device boot logic are broken now, there is no default 192.168.88.1 here on device.

Tried two different Windows PC, tried different versions of NetInstall ( 7.15.3 stable / 6.49.13 stable / 6.49.11 ) - no success.
Tried with Linux as well, but there’s no device in a list of NetInstall app.

Is there any way to format flash drive on device somehow?

UPD:

works with old PC (windows) with version of NetInstaller 7.15 ( other versions does’t show up an device ).

tried to upload 7.15 ( arm, arm64, MIPSBE, MMIPS ) - says installed, but still nothing changed.

After rebooting router can’t detect for default 192.168.88.1 ip

UPD:

success only with 6.49.17 firmware ( arm ).

After that don’t afraid that your ethernet still not connected.

  1. set any IP like 172.18.18.1 to your interface (ethernet)
  2. Open up Winbox
  3. Go to Neighbors section - click Refresh
  4. See your device Mac address - click on Connect button.


    PS. Sometimes reset button need to be pushed harder as you expected.
