Network performance shows disconnects and reconnects 5 to 10+ times a day

y network performance screens shows many disconnects and they are always almost exactly 2 minutes long.  I checked with my ISP and they didn't see any problems and also replaced the cable to my residence just to be sure.  They checked my modem and they haven't seen any downtime in the last 7 days and the signal looks great.

I can't tell when this started occurring because only the last 7 days of events are listed.  I have tried restarting all my equipment but the problem persists.

The disconnection definitely doesn't last 2 minutes, I notice hiccups if I am streaming something and whenever I check it always corresponds to an event, but the stream continues in about 2 seconds.

It feels like the Firewalla is doing some sort of maintenance or some process is running that is tying up the device and then clearing.  I don't see any pattern to the times that it happens either.  I also don't have a spare router to hook up to make sure it is the Firewalla causing the issue.

Any ideas on where to go from here?

Thanks

     Does the cable used between modem and Firewalla also changed? I often see this happen due to unstable physical connections. When Firewalla says the ISP is down, does it often come with a port disconnect event?

    I replaced the cable between the modem and Firewalla last night and still saw the disconnects when I got up this morning.

     

    There is no port disconnect associated with the events, just ISP disconnected then almost 2 minutes later ISP restored.

    Best look at this article https://help.firewalla.com/hc/en-us/articles/360053534593-How-do-I-debug-network-connectivity-issues

    I think the best way is trace if the problem is your LAN or WAN. See if you can run a ping from LAN to firewalla router LAN IP, and see if any disconnect there

    "See if you can run a ping from LAN to firewalla router LAN IP, and see if any disconnect there"

    I didnt see any problem pinging it but it is very intermittent and the duration is very short so I wouldnt be able to try anything when I notice the connection down.

    I did notice that I didnt have any disconnects this weekend when one of my computers was off.  As soon as it came online today I noticed a disconnect.  Im not sure what that computer could possibly be doing to the Firewall to cause disconnects though.  Also it doesnt stop immediately after the machine is shut off, I have noticed disconnects after it was turned off.  So possibly not related.

    you can run a long lasting ping, just get a terminal and keep the ping there. 

    If you feel the computer is an issue, check and make sure it is not running anything (like antivirus) that may be scanning your network or doing anything on the network. Once we found one PC was doing a scanning and it was disconnecting another PC running antivirus
