Missing Downstream Channels

I have recently been having issues getting all downstream channels.  When I login to xfinity to check status it says no issues detected, but when I open a chat window it immediately says it has detected an issue and wants to schedule a service call.  I guess I will eventually go that route, but it just seems like an issue in the network, no on my end., so was just checking if anyone had any similar experiences and any tips?  Reboots/restarts are not helping.  Using Netgear CBR750.

Hey there girarja 👋 I appreciate you coming to our community to let us know about the downstream issues you noticed, and you're in the best place for help! Has anything changed since creating your post or did you end up scheduling a service technician? I understand how things could be confusing when our site and chat are giving you conflicting updates on the status of your services, so we can dig into things deeper if needed 👍

Thanks.  The missing channels re-appeared but are not stable (high error counts).  My connection seems 'ok' so I have not called for a technician yet, but I do not have high hopes that the connection will remain stable if error rates do not improve.  Thanks.

I appreciate the update and glad to hear your connections aren't giving you too much trouble as of late 👍 We can check in with you again in a few days just to make sure things seem stable before getting your post all the way closed up, but we're also still happy to check things on your account further to ensure we're not seeing any red flags on our end too.

If you'd like us to check things out, send us a direct chat message with your full name, the name listed on the account (if different), and the full service address associated with your account to “Xfinity Support”. To do so, click on the chat icon located at the top right of this forums page.
