My router probably broken ?

RouterOS Beginner Basics
1

Hello,
Yesterday I tried to upgrade to the last stable version.
When I pressed “Download and Install” button, then nothing happens. After a few seconds I hear a bip.

  • The sfp led was off.
  • The PWR blue led on
  • bip every 10 secondes
    I asked my neighbour: his fiber connection was ok.

I decided to do a short reset: no bips but no signal
I decided to do a long reset.

Winbox does’t display the mac address
I changed the mask to 255.255.0.0
A ping of 192.168.88.1 gives destination host unreachable.

I don’t know how to re-establish a connection with my router.
I bought it in September.
Any suggestion one week before Xmax :frowning:

Try to connect to MAC server.

Sorry but I don’t understand: be explicit please

Run Winbox, click “Neighbours” tab and wait for discovered devices.
Then click on MAC address field, not IP one !!!
Put credentials and connect. You do not need any IP if you use MAC address.

Thank you @BartoszP
I clicked Neighbours: no discovered device
I tried refresh: idem
Note:cable on ether1, bip every 10 seconds after power off/on

7

Try to disable antivirus program, switch off WiFi…leave just cable …

8

no antivirus !
no wifi
just the router connected on a switch to a computer

Note: I downloaded and installed mactelnet on linux debian
I typed the mac address of the router: connection failed
I tried both mac addresses

I think it’s time for https://wiki.mikrotik.com/wiki/Manual:Netinstall

Before netInstalling the machine, try a different port than ether1 for the moment.
ether1 is default for WAN in many devices, so it’s not unlikely that MAC server is disabled on that particular interface.

I downloaded netinstall and installed it
I connect my cable on ether7 port (because ccr)
I turn the power off
With Net booting, I set an IP (192.168.1.199)
I pressed the reset button and turn on the power …

Now I see the mac address with the status of ready !!!

Yes it was really the time for netinstall

I downloaded the TILE 6.40.5 .npk file, browse, install and reboot
I tried again with winbox: no mac address detected ???
I tried with the new ip (192.168.1.199): error could not connect

After several attempts (?) , winbox has discovered the router
Thank you very much. You save my life before Xmas !

Next time, I will do a backup OUTSIDE of the router before to upgrade it.
I don’t understand this failure during the upgrade.
