Hello. I have an SB8200, Docsis 3.1. Although I pay for gigabit speed, numerous calls to comcast customer support over the year never gets my modem "activated" to use gigabit. I have been paying for it for over a year. I always get frustrated by comcast support and then give up. Is there anyway to get through to someone that can help me.
Today the support tech told me to "call" my modem manufacturer to make sure the modem is gigabit compatible. Yikes.
Here is a screenshot of my SB8200 status page.
Can't see your pic. Since you are a new poster, it needs to be approved by a Forum Admin. That could take some time. In the interim, you could try hosting it at one of those free third-party pic hosting sites like Imgur or Photobucket and post the link to it here.
Please also post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers, and the error log entries.
