XB8 connection issues - packet loss when on 5GHz WiFi
I've been going back and forth with Comcast reps about it and it doesn't seem like we can get on the same page.
On 9/13, I started having issues with intermittent packet loss. This only happens when I'm connected to the XB8 router via wifi. The packet loss occurs between the client machine and the router and is not dependent on the internet connection. The wired connection works fine, wireless connection to a different router/access point also works fine, so I'm suspecting some fault with the router that started manifesting itself that week. I tried restarting the router and testing from a different machine, and I'm experiencing the same issues.
A Comcast technician stopped by on 9/20 and replaced the XB8 modem with another unit, and the issue with 5GHz WiFi connectivity was temporarily resolved.
Unfortunately, as of late night of 9/26, the issue came back. It looks like the modem was reset around 2-3 am CST, and after that, my problem with the 5GHz WiFi connection has returned. It appears like the software/firmware update that the modem is receiving is causing this problem.
I got another technician visit on 9/30 and he replaced the modem again. Once more, the issue was temporarily resolved. However, around 3 am CST last night, the modem appears to have received an update and after it restarted, the issue came back yet again.
I left one of my machines up and testing connectivity to the modem overnight and I was able to capture the packet loss as it started appearing:

Since this appears to be a clear issue with the firmware that is being pushed to my modem, and technicians aren't able to solve this aside from just continuously replacing my device every day, I am looking for a way to get this escalated to someone who can help aside from technician visits where all they do is swap out my modem repeatedly. This issue is currently interfering with my day-to-day work.
