You can select that the current configuration must be saved.
With netinstall everything set to default settings.

Did You solve this problem?

my RB951G is doing the same thing (reboots every 5 sec). Does NetInstall work if router is rebooting all the time???

You can try netinstall maby if starts netbooting the routerboard not reboot every 5 seconds.
See here for the procedure

Success and let me know if it works

Also, if possible, could you try a different power adapter? It might be that your power adapter has partially broken and is unable to deliver the needed power continuously.

Hi,

Thank you for replying. Eventually I did managed to put it in the netboot and do NetInstall but there were some other problems with the routerboard (reasons why i needed NetInstall in a first place) so I sent it back for a replacement.

Goodluck and thanks for let us know

In many cases a Routerboard rebooting over and over can be caused by a loop - either external (cabled loop) or internal (like f.eks. VLAn’s bridged wrong together causing a traffic loop).
