Hey @mcolbourn,
Welcome back to the community and thanks for taking the time to post.
I'm sorry to hear of the issues with your connection and as @jb66 and @carl_pearce have advised that you only have one upstream channel and we will need to send out a technician to resolve this.
I can arrange the appointment from here but would need to confirm a few details via a private message, that I will drop over in a moment.
Please look out for the private message and we can get started.
Regards,
Steven_L
