eth0 frequent disconnects on ASRock Rack E3C226D2I

[b1lou]

Hello,

 

I've noticed some frequent disconnects on my samba share for a few weeks now, but never had the time to really follow up on it until yesterday. So yesterday I looked into the smb logs but couldn't find anything abnormal, but the dmesg log showed frequent disconnects on eth0:

My Board is a ASRock Rack E3C226D2I with Intel i210 NICs that should be supported by XPEnology out of the box.

I can't really tell when the problems started, but I'm pretty sure nothing changed on the hardware side since then.

I'm on DSM 5.2-5592 Update 4.

 

Any ideas what could cause the problems?

I've pinged the NAS from three different computers and all pings were interrupted at the same time. So the problem is definitely on the NAS side.

 

Anyone?

Just a heads up for anyone who has similar problems: My NETGEAR GS116Ev2 caused the disconnects. I even got a replacement unit from NETGEAR, but I had the exact same problems. I've now replaced the NETGEAR switch with a TP-LINK TL-SG3216 and everything works like a charm.
