SB6121 issues

 I upgraded my modem from a docsis 2 to a docsis 3 modem. I got a motorola sb6121 from newegg.com. This modem is brand new. I called up cox tech support and the person that I talked to asked for the model of the modem and she also asked for the customer s/n and HFC Mac ID. I gave those numbers to her.

Now an hour ago I noticed that I was not able to get a connection. I am able to go cox.net but the speed was so slow. I don't know if there was an outage in our area. I found out later on from someone in chat support that there was none. So I don't know if the modem was causing this problem but now everything seems ok.

I don't see anything unusual with the connection as of now.  Are you still experiencing problems?

Not anymore. According to the tech support guy that I talked to the modem was just provisioning itself that's why it acted that way. IT's all good now.
