No Ranging Response received - T3 time-out

[lawrmc]

Hi.

We had our Virgin FIbre install a couple months back and we keep getting intermittent issues with connection. Checking the router status I see the error - No Ranging Response received - T3 time-out

We have a HUB 3.0. Noticed some other posts in this forum with the logs form the router so posting them below. Hope someone can advice/assist/help. 🙂

We've rebooted the router a few times over past month, issue keeps coming back.

If they are preceded by the accompanying DHCP Renew, that is quite normal.  It is to do with the way VM's DHCP is setup.

See my network log below;

Yeah it is.
