There does not seem to be any obvious problems on your end. I'm not sure there is much advice we can offer you other than "call for a tech".

I have the same issue. Just connected the SB6121 today. Download speed doubled from 12 to 24 Mbps, but upload decreased from 3.5 Mb down to .75. I have sent an email to Steve with the MAC address
