I own a SB6121 and as of last my internet dropped out and came back in about 20 minutes; however, now the modem will not channel bond (only connected to one channel). I have accessed the status page and reset the modem to defaults. I called comcast support and was told that they have to send out a tech as a owned modem cannot be accessed remotely. It seems as if this might be some type of provissioning issue. Is there anything else I should try before having a tech come out? I have 50/10 service (getting 30/10 now).
Thank You
