Hi there,
since last week, I’ve been having problemas with the interfaces tab.It shows them all, but all of sudden, they desapear and it shows a erro message, which I can´t remeber what it says, something about timeout. BTW, it has only LAN interfaces.
Any help ?
upgrade to higher Version of ROS 
OK,
but it´s been working fone for 6 or more months. I don´t think it would be te problem. right ?
Where does it happen? in winbox or Telnet ?
After that, can you access other Router resource?
What about ping the interfaces? are they reachable?
What is your Hardware? x86 or Mikrotik Integrated RB? Which model?
Do you update the firmware of Router board not ROS? >>
system routerboard print
routerboard: yes
model: 750G
serial-number: XXXXXXXXX
current-firmware: 2.36
upgrade-firmware: 2.36
Check whether your RB is Updated or not
It happens after I logged on to the server.
How do you logon? winbox or Telnet ?
throguh winbox, I scan, see the mikrotik, and I log in.
The interfaces are there, and all of sudden, they´re gone.
Give more info if you want result!
also answer to these:
After they´re gone no PPoE client can log on.
