Odroid-C2 - wired network flapping

sircurse · October 14, 2017 at 1:59 AM

Hi experts,

I m experiencing issues with my network, it is always flapping and cannot watch a movie (NAS storage), I have tried fixed IP, DHCP, rebooted the router, etc..

But it keeps connecting and disconnecting.

I have generated the following logs:

DHgN

Something that I have noticed is that connection wont go up to 1000BaseT, even the Odroid-C2 and router supporting these speeds, I dont think it has any matter to the issue flapping but it also weird.

I have tried all versions of LibreELEC possible since 7.90, all those version have the same issue, now I m running 8.1.2 (beta).

Someone can help me on it? Saddly I have prepared all the infra to support 3 Odroids-C2 in my home connected to the NAS, but even the first KODI is working properly.

Thanks in advance,

Anderson.

Flapping? I am not familar with that term? What exactly do you mean?

Link Up/Down, consecutively, hard to get more than 5 minutes of connection before it goes down again.

OK, actually that is quite a graphic term for it isn't it.

Can you try turning off ipv6?

Also, what lease time is your DHCP server giving out?

Ipv6 is already off, it used to have fixed IP, btw the DHCP has also fixed lease of IP to the device mac-address.
