Persistent Packet Loss and Gateway Offline Issues with Xfinity

Hello everyone,

I've been facing an ongoing issue with packet loss and intermittent gateway outages since moving into my new home this January. Despite having six different technicians come and assess the situation, the problem still persists. I'd greatly appreciate your insights on this matter.

Initially, the technicians mentioned that the connections outside my house were faulty. Then, they discovered that the line from the pole to my house was damaged and loose. However, even after these issues were supposedly resolved, I continue to experience packet loss and occasional gateway outages. After the suggested it might be my personal router and to only use the Xfinity Cable/Modem to check if the problem persist which it did. I've had three different Modems replaced with the issue still not being resolved.

During the last visit, one technician noted some minor problems, such as improperly crimped cables. He suggested I could potentially have faulty ethernet cables so, I ran the modem WIFI only with no ethernet cables connected and the problem still persist!

Considering the repeated occurrences and the efforts made by the technicians so far, I'm seeking advice from the community. Has anyone encountered a similar problem with Xfinity? If so, what steps did you take to resolve it? Are there any specific troubleshooting methods I should try? I'd appreciate any recommendations or insights any of you might have regarding this frustrating issue.

Thank you in advance for your help!
