C7000 Frequent Disconnects
Hi all,
After about 6 months of reliable internet, I've started receiving frequent T3 and T4 errors. Based on some internet searching, it looks like this problem is usually due to noise in the stream channels. My understanding is that excess noise can cause excessive power requirements in the upstream channels, however from what I can see my upstream power levels seem reasonable (please correct me if I'm wrong).
My question is, based on the connection quality and the errors I am recieving, is more likely that the issue is with my modem, or should I continue to investigate noise in the lines?
I have tried both active cable jacks in my house and there is only one two way splitter from the outside line in my garage.
Thanks in advance for any guidance received.
P.S. I've tried to post my issue twice before but it does not show up in the forums. I've tried again, this time posting the event log and channel bonding data as screenshots due to what I belive may be a copy/paste issue based on this post.

This could be a issue of lines in your area you may need the ISP tech to come check things out.

Darren,
Thanks for the response. As you suggested, I had a tech come to my home to check things out. Based on his testing, he could not identify any issues with the the signal coming from the drop box, nor any issue with the cabling in my house. He did replace the lone splitter and all coax connections, stating bad coax connections can cause the symptoms I saw. Despite the troubleshooting efforts, I am still getting T3 and T4 timeouts with the same regularity as before. It seems to me that whatever is causing the issue is very transient in nature, and probably not associated with the lines on my property.
If I have the ISP send another tech back out, is there anything in particular I should ask them to investigate? The tech thought it was not likely an issue with my modem, but I'm considering leasing a modem through the ISP for one billing period to at least rule out the possibility.

Kind of a hard issue to pin down could be issues down the line past what the tech checked out but yes you could try renting a modem for a month just to rule that out.
