Hey everyone. Just bought a rb5009ug+s+in. Firmware and routerOS are both on 7.7. Small issue I'm having and having trouble finding anything on the forums. Every 10 mins my lan port goes into a link down, then up state, disconnecting me from winbox and dropping internet to that port. I'm using ppooe login for CenturyLink fiber with vlanID 201. Has anyone seen anything that could potentially fix this issue? My cat5 cable is confirmed working. I tried ether2 and ether 3,4,5,6,7,8 ports to rule out a fouled port. Out of ideas and I am not ready to fully deploy the router yet until this issue is corrected. Thanks.
Tried 3 different working cat5e cables. tried different ports on the router.
TIA
