Hey @jambroseyeah, thanks for reaching out to Xfinity Support on our forums and sending the logs! Disconnects can sure make it hard to work and I'd love to help. Looking at the signal levels, they all look to be fine. For the errors, timeouts are basically just saying when we check on the modem it is taking to long to get a response. T1 being a shorter time frame up to T4 a longer time frame. With your signal levels being good, it can indicate there is interference or an issue in the area causing it. Can you send us a direct message so I can take a look?

To send a direct message:

Click "Sign In" if necessary

• Click the "Direct messaging" icon near the top right of the page

• Type "Xfinity Support" in the "To:" line and select "Xfinity Support" from the drop-down list which appears. The "Xfinity Support" graphic replaces the "To:" line

• Type your message in the text area near the bottom of the window

• Press Enter to send it
