Problems Upgrading RB333

Hello.

I just got an old RB333:

[admin@MikroTik] > system routerboard print
routerboard: yes
model: “333”
serial-number: “179801C16DA1”
current-firmware: “2.18”
upgrade-firmware: “2.18”

Is acting weird. I set an ip address to eth1 but, I can’t access it by ip address only by mac address through Winbox. This happened after upgrading the bootloader: system routerboard upgrade.

I can’t upgrade it to a newer RouterOS version… How can I do it?

I’ve done some googling and can’t get anywhere.

Thanks in advanced for your help.

Run /system reset-configuration and add appropriate /ip address (maybe ip route), /ip address should be from the same network as address of your computer.
