I had the Motorola Surfboard.But had it swapped out because On my computer I keep getting "Can't locate Server. and I have to Disable the Ethernet adapter on my computer and then enable. Sometimes I have to do it various times or Power cycle my Modem and My NetgearWGR614 v6,Or even Restart computer... I talked to Comcast and they said It was the modem acting out because it wasnt a DOCSIS3 so I had it swapped out today.
Now It keeps doing it sometimes My connection stays for few hours,or few mins.
I have done the DNSflush,and renewed all the IPs,and also have done tons of power cycle on the modem and router.
What is going on?
