I'm trying to understand the source of an event that is causing my Verizon provided Actiontec MI424WR gateway to hang. With the understanding, I would like to takes steps to ensure it does not happen in the future.
I experience the hang multiple times a day (a dozen or so), and they last from 20 or 30 seconds to one or two minutes. Then things go back to normal.
The hang is experienced as "internet down" and unresponsive gateway. Web pages fail to load; and ping
'ing the gateway results in timeouts.
The hang occurs on both the Ethernet interfaces (desktop computers hard wired) and the Wifi interface (iPads and other devices connected wirelessly).
Grepping the gateway's logs, I've correlated the event to this log entry:
TIME EVENT EVENT TYPE DETAILS
Jan 30 11:41:40 2014 System Log LAN Coax LAN Coax Link Low Rate <TX 168Mbps/RX 164Mbps>
Jan 30 11:41:40 2014 System Log WAN Coax WAN Coax Link Rate <TX 227Mbps/RX 240Mbps>
The full display from the event log is shown below and the event was logged at 11:41 AM. I've got a script running that tests for the hang (its that frequent), and the event actually occurred between 11:39 - 11:40 AM (it was just logged 11:41).
When I move to Traffic Monitoring page as shown below, I see that all the traffic monitor statistics have been reset. For example, the Time Span (uptime?) shown below is 24 minutes, and that is the time elapsed between now (12:05 PM) and the event (11:40 AM).
EDIT: from the System Monitoring -> Router Status page, the following applies to the gateway:
Firmware Version: 40.21.10.2
Model Name: MI424WR-GEN3I
Hardware Version: I
Serial Number: CSJI2031010495
According to the Advanced -> Firmware Upgrade page, the gateway does not have any upgrades available:
What is causing this event?
What can I do so I don't experience the frequent loss of service?
