my RB2011UAS-2HnD-IN started a problem yesterday when I came back from work. No activity light on the WAN (eth1 port) and cannot connect Winbox on the router (router unreachable). Tried to reboot, check logs, firewall, reset to factory default, and etc... Update to newest firmware (6.15) it works all night. Now when i came back from work again, router seems hang... LED lights on WAN (eth1) and LAN (eth4) is on static. Same, cannot connect to the router by Winbox. Need to restart and will work only in a few minutes then back to hanging.

Is there any way I can make this work again? Warranty just ended (bought it last year July 12, 2013).. Really sad.... I thought this would last for many years...

Another question, is there any ways that I can transfer the OS license to another machine? I might just build a DIY pc firewall and make use of the license.

Try a netinstall.

Please update your RouterBOARD firmware too! You can do it by /system routerboard update and /system reboot.
Firmware update will happen automatically, if you install 6.16 version.

License comes for for free with RouterBOARD, that's why it is not transferable.

thanks for the replies. i have done the netinstall. ill check tomorrow if the problem still exist... thanks a lot....

Seems my router is ok for now. From last night until today, not experiencing any hang or whatsoever...

cbrown & sergejs,

Thanks so much for the info.

Seems like that my router really died Although it still powers up and can console on it, I tried to do the netinstall again but the router doesn't response while im trying to connect the LAN cable from pc to the router.

I did last time successfully re-install the routerOS by netinstall but now, no luck.

Is there any guide that I can use to revive my router? Thanks in advance.
