I have a Siemens C2110 modem router.

My PC is connected through LAN or ethernet cable.
Every now and then I am disconnected(interval of 10 ot 15 minutes) from internet.
Link(orange light) is blinking and I get '678 error'.

But when I connect my PC using USB cable modem works fine.
Disconnection is very rare once or twice in a day.

So,what may be the reason my ISP or the modem ?

Thank you.....
