My ROS frequently logged Link up/down (in 1-2sec)
few times a day on both ether1 and ether3
Routerboard Model: RB1100AHx2
Version : ROS 5.20
Ether1 Connect to WAN with dhcp client
Only linkage with 1 computer in Ether3
How can i solve this ??
thank you very much
did you have same problem before upgrading?
Yes, Before upgrade, i also have this probrlem
But i notice that, it happen on random port…
keep link down link up link down link up within few seconds.
then it work normal and repeat happen again later
Did you have the router bootloader (firmware) upgraded?
A quick search shows several people with this same problem on this device in just the past couple of weeks.
Everyone REALLY needs to send this particular problem to support@mikrotik.com so they will take it seriously! It seems to be widespread now.
Whats the auto-negotiation setting of the device on the other end of that port?
