random Ethernet disconnection

[pawlu]

I have been using Kodi Insengard and Jarvis on four machines, namely , Raspberry pi 2, with both OSMC and Openelec, Orange pi, with Android 5, a Chinese quodcore box, with Android4.4 and Jarvis on windows 10

I am expierencing occassional loss of ethernet connection on all these devices and operating systems, except windows10. The wifi connection is not effected, and remains fully operational. My cat6 cable and rj45 have been tested ok. My isp has even changed my modem! Sometimes, resetting the modem, and/or device cleared the problem, but, it turns back at random.

What is to blame?

Hmm.. perhaps a Mac adress issue?
Many user have Mac adress issues.. (just do a search) causing router problems (disconnects/speed drops ect)
-some android devices keep changing there mac adress, causing havoc on some routers, as it might be perceived as a hacker attack
Try checking your router log(s)

Cheers

Can an ISP or malware cause this?
