Sorry if this is already posted some were, but I have a couple 411AH boards that are set up as AP’s. Two of them right now lock up at least once a day. When I say lock up they are still up and operation with clients connected to them, But I cant log into them via MAC or IP and the connected clients loose the connection out to the web. One way I have been fixing it is MAC telneting in through a connected client and then doing a reboot on the AP. that will bring it back up for at least a day or 2. I have now downgraded back to RouterOS 5.2 and disabled SNMP, because i have seen were that has helped others. My question is could this issue be caused by the heat. I am in Texas and we have been averaging about 106 every day if not higher.
if this happens again, instead of rebooting, first make a supout.rif file during this frozen state. only after it’s done, then reboot. send the file to mikrotik support.
The RB411AH should have no problems to operate even at 160F temperature.
