Frequent "Network Cable Unplugged" Problem

[probuddha]

Friends,

Of late I am facing a weird problem which is hampering my work a lot.

My Modem is connected through the LAN and I frequently get the message "Network Cable Unplugged" and within a minute it gets reconnected again...and then after 10 - 15 mins, it gets disconnected with the same error message.

My connection details are as follows:

Modem - UT300R2U
Mode - Dialer

SNR & Attenuation details:



Do you guys think that it's a problem with the LAN card, the RJ45 cable or anything else?

Any advice will be highly appreciated.

Thanks a lot!

RJ45 cable. Then Lan card settings.
