Intermittent Connection Drops
Hello, I've been experiencing intermittent connection drops (for 5 seconds every 10 minutes or so). I have verified that this issue exists BOTH on WiFi and Ethernet, on 4 different computers and devices (i.e. Apple TVs).
About two months ago, I was experiencing the same thing and reached out to Comcast. They said they noticed a problem on the green box outside my home and needed to repair something (didn't specify). At the same time, they provided me a new Comcast XB7 modem (previously was an XB6). This seemed to resolve the issue, until about a week and a half ago. My Setup is the XB7 in Bridge Mode to a UniFi USG. To try to troubleshoot, I have parallel ping tests. I have run the pings to these destinations:
- Google.com - Ping will drop packets when the connection drops
- Facebook.com - Ping will drop packets when the connection drops
- 10.0.0.1 (XB7 in Bridge Mode) - No packet losss when the connection drops
- 10.1.90.1 (USG) - No packet loss when the connection drops
Therefore, I believe it is a problem with the external network on the WAN side.
I tried to call comcast and they said because of COVID they couldn't do anything since the connection isn't completely down / I have some service. Has anyone experienced this before? Here are my modem levels:
