Fort Myers Persistent Packet Loss Issues During Peak Hours Despite Troubleshooting

Hello everyone, I am reaching out for assistance with a persistent packet loss issue that I've been experiencing primarily during peak hours (5-10 PM). I have conducted extensive troubleshooting on my end, but the issue persists. I am connected directly to the Xfinity modem via Ethernet. I have also tested the connection using a different device connected to a separate mesh network, and the same packet loss occurs. This issue is not isolated to one device or one type of connection in my home.

Here's a summary of the troubleshooting steps I've taken so far:

1. Ensured that all devices are correctly set up and located in a well-ventilated area.
2. Checked for possible signal interference and found none.
3. Tested the connection during different times of the day. The packet loss primarily occurs during peak hours, suggesting a possible network congestion issue.
4. Called Comcast support multiple times, but the issue remains unresolved (they want to send a technician which I understand, but based on the rest of this post I wanted to check with the forums first as it seems highly unlikely to be a local issue due to it only happening at the same time of day)
5. Monitored network usage to rule out the possibility of bandwidth overuse on my end.

Additionally, the majority of the lost packets are upload packets. Given the steps I've taken, I am led to believe that this issue may be on Comcast's end, possibly due to network congestion during peak hours. I would greatly appreciate any insights, advice, or potential solutions from the community before escalating this issue further or seeing a technician.

Thank you in advance for your time and assistance.
