Hello Forum,

I’m in a problem upgrading Routerboard OS for 951Ui-2HnD to the latest version 6.43.7 but failed.
Tried in several ways like below,

  • Direct upgrading from MikroTik with internet “Download & Install” but returned “ERROR: could not resolve dns name” and continuously failed.


  • Uploaded “routeros-mipsbe-6.43.7.npk” file and reboot but failed.


  • Tried to reach by “netinstall” and unable to detect device in “netinstall”

Requesting if you please advice and help me get solve this problem. For your reference, given below the device information in below.
Also it is notable that, few days ago this device been provisioned with some scripting, scheduler & dns replaced with unknown for which I’ve reset to default & will do reconfigure after upgrade.

This sounds like your router has been compromised which prevents you from upgrading it. The only cure seems to be netinstall … which is a quite fragile process and you have to be persistent trying to complete it.

After you succeed to upgrade router, don’t simply apply saved configuration backup. Rather start from factory default and make necessary modifications by hand.

Hi Metod,

Thanks for your prompt revert & your thought also in my mind. But to do with “netinstall” I may not be identifying the accurate process.
Would you please help me getting exact & multiple way-out to reach to my goal.

I don’t have much to add to what’s written in netinstall manual. Perhaps only a couple of things:

  • you might want to actually disable the firewall on windows machine
  • you can try to run netinstall binary as administrator
  • sometimes it helps to have a dumb ethernet switch between router and windows machine (but nothing else should be connected to that switch not to interfer with the netinstall process)
  • I’ve always manually downloaded ROS packages from Mikrotik download page (be sure to get packages for correct architecture). According to manual that might not be necessary, but you may want to download it anyway, just in case …
