Connection Disconnects

[viperius]

Hi my network has been working fine and in the last 3 months it has started randomly disconnecting. This happens 4 or five time a day....

I have a hub 3 in modem mode

Unify Dream machine as my router.

All connected via ethernet.

I have extracted this from the logs. Seems when I am time traveling back to 1970 it causes some problems.

Thanks for any insight

FYI - 01/01/1970 is usually when your hub reboots and it has yet to get the time from the VM CMTS.

Please post your up/downstream stats and set up a BQM.

I have had a BQM going for a while and the graph seem to be blank.

Good Afternoon viprius, and thanks for your post on our Community Forums, and a very warm welcome to you!

Can you please provide us with an update as to how the services have performed over the weekend? Do you have any graphs from the BQM or a live link that you can refer us to?

Kindest regards,

David_Bn

You need to set up a firewall rule to “Accept ICMP traffic” in the dream machine because pings from the internet are blocked by default and that’s what the BQM uses.

[viperius]

ok update from the weekend is that there have been no further drops in connectivity.

I have enabled the UDM firewall rule so hopefully we should get a BQM graph shortly.

Thanks viperius 

Looking forward to the BQM

I think I must be doing something wrong as the graph is still red.....

Are you sure it is the right IP address being monitored?
