Hi all,

 

The network speed on Unraid keeps dropping from 1000mbps to 100mbps i have attached some logs to help

server01-diagnostics-20240718-2244.zip

The logs show the L\aN connecting at 100 Mbps.   This is typically due to a bad LAN cable (or port) so not all 4 twisted pairs in the cable are making end-to-end contact (100 Mbps only requires 2 to be working). 

strange as i see this in the logs
 

Jul 18 22:29:12 Server01 kernel: r8125: eth0: link up
Jul 18 22:29:12 Server01 kernel: bond0: (slave eth0): link status definitely up, 1000 Mbps full duplex
Jul 18 22:29:12 Server01 kernel: bond0: (slave eth0): making interface the new active one
Jul 18 22:29:12 Server01 kernel: device eth0 entered promiscuous mode
Jul 18 22:29:12 Server01 kernel: bond0: active interface up!
Jul 18 22:29:12 Server01 kernel: br0: port 1(bond0) entered blocking state
Jul 18 22:29:12 Server01 kernel: br0: port 1(bond0) entered forwarding state
Jul 18 22:33:42 Server01 kernel: r8125: eth0: link down
Jul 18 22:33:42 Server01 kernel: bond0: (slave eth0): link status definitely down, disabling slave
Jul 18 22:33:42 Server01 kernel: device eth0 left promiscuous mode
Jul 18 22:33:42 Server01 kernel: bond0: now running without any active interface!
Jul 18 22:33:42 Server01 kernel: br0: port 1(bond0) entered disabled state
Jul 18 22:33:54 Server01 kernel: r8125: eth0: link up
Jul 18 22:33:54 Server01 kernel: bond0: (slave eth0): link status definitely up, 100 Mbps full duplex
Jul 18 22:33:54 Server01 kernel: bond0: (slave eth0): making interface the new active one
Jul 18 22:33:54 Server01 kernel: device eth0 entered promiscuous mode

 

Then it went back to 100mbps will have to do some more tests at the weekend will move it onto a different network socket in the wall to see if its maybe a wiring issue

also its a realtek network adapter so i wonder if that might be causing an issue
