I have a router Cisco 871+ for Ethernet Access 1Mbps.However for the past few months, I have been encountering intermittent network disconnection at least twice a month. I have checked with my ISP - they have performed some circuit test on their side & prove that everything is stable. They have replaced the NTU unit as well but the problem still persist. Could it be the fault of the router or otherwise? Any ideas?
Appreciate your assistance. Thanks.
