Hello!
Happy user of a few Mikrotik switches - all running SwOS. Never had an issue in the past!
New CRS309-1G-8S-IN arrived yesterday.
- First boot, went into RouterOS, Accessed UI via 192.168.88.1 as expected.
- Logged in with password sticker on the back
- Changed to a new admin password
- Set up SNMP
- Add static reservation and hostname to external DHCP server
- Went to firmware upgrade in RouterOS. Saw there was a new one available and clicked "upgrade and restart" or the equivalent.
Then I was able to access the WebUI on the expected hostname. But when I tried to log in, neither the new password or the original (from the sticker on the device) worked.
Then it seemed to reboot and I noticed it was back on the original 192.168.88.1 address, but only for 20 seconds or so.
Then I tried power-cycling and waiting a few more times...
I tried the "hold the reset button in while powering on an release after a few seconds" thing.
Where am I now?
When I power on the device, I get nothing on the reserved IP or the factory default IP. I do see my DHCP server logs spammed with logs like:
2026-08-12 09:45:21.666 BOOTP(eth0) d0:ea:11:f6:90:02 no address configured
Hundreds of entries.
Another observation, the device makes a little noise every few minutes - maybe it's rebooting? Hard to describe the noise.
So, it's trying to netboot, but I don't have a netboot server set up.
How can I just "reset" to factory defaults again? Is this Netboot / BOOTP loop going to continue until I can give it a netinstall software package to use?
I will keep trying but wondered if there was an obvious mistake I have made here.
Thank you in advance
, though "strange" (it is rather common that a device is set to 0.0.0.0 for some reasons, but usually as soon as the DHCP client is reset/enabled it gets an IP address from DHCP server immediately, in a matter of a few seconds at most).
