Hello everyone,

I've ended up with mikrotik rebooting every 10 seconds. Out-of-warranty but working fine until the upgrade.

exactly like in this video:

It's unresponsive to both of reset buttons and it does not show up in netinstall anymore.

What can I do?

Thank you!

Some failure during upgrade. If you back up the settings in your RB you can try the netinstall recovery procedure as described in

Thanks, but how can the video you posted help me? As I said in my original post: "it does not show up in netinstall anymore"

I have the same problem with RBwAP2nD. It work in CAPsMAN mode with RB2011iL-RM. After each! upgrade(in manual or automatic mode via CAPsMAN or package upgrade) RBwAP2nD don't work. Every time I need to use Netinstall software to reinstall it. I already tried to change RBwAP2nD to another RBwAP2nD. With new one I have the same problem.
