Re: [Signals] SB6121 new firmware messed up my upstream!
I too have been having issues since purchasing the SB6121 and called comcast about the issue. They sent out a tech and he thought my incident was due to a faulty network adapter (onboard nVidia 10/100/1000).
He tried the modem with his laptop and the network was stable and was able to connect to the internet. I also have a netbook but the adapter is 10/100 and it has held a stable internet connection since his departure until the evening when i powered it down (have not been home since this morning so unsure about during the day today).
It might not be your issue but it something to look into 1) try a different computer/laptop/netbook to see if you get a stable signal 2) look at your network adapter and try a 10/100 adapter if you have one to see if it is related to 1000 speed adapters.
I am not a expert in any way/shape/or form but these are things that I have thought might be the problem.
