mám už 4ks RB4011, který to dělaj, dalších 30 jich jede bez problému i na starších FW. Nepomohl ani update na poslední stable verzi, po měsíci zas vše funguje, jen se do ní nelze přes winbox dostat... restartoval jsem ji, vygeneroval supout.rif poslal ho na support a tohle je odpověď: From your provided supout.rif file we see that several programs have crashed, and it may be caused due to hardware failure. If the device is still covered by warranty, please follow two of the options below:
If you have purchased this device directly from MikroTik, please use the RMA system in your distributor account and start a warranty process referring to this support ticket with a precise "Problem" name and "Problem description".
If the device was not bought directly from MikroTik, please contact the distributor or the company you bought the device from, and ask for RMA warranty repair and further instructions.
takže asi tak...
