Re: Intermittent No Ranging Response received - T3 time-out

The odd T3 timeout every few days is normal for cable.  Your power levels and SNR look OK, the upstream error counts look to me to be too high (I'm reading as 17 T3 timeouts on downstream ch 1, and respectively 7, 6 and 5 on the other three channels?), as do the downstream post-RS error count.  Pre-RS errors on the downstream are not significant.  On a cable connection errors always build up over time, and are zeroed when the hub is restarted by you, so I suggest that you restart the hub, let it run for around 12 or 24 hours and then repost the full data set.  It'll be easier for us to read if you do it as follows, which should hopefully keep the formatting:

Connect to the hub by clicking on this link http://192.168.0.1/  That should pull up the log in page for the hub.  But don't log in, just click on the link "Check router status"  That'll bring up a window with five tabs.  Open the Downstream tab.  Select all the text (Ctrl-A if using a keyboard), copy it (Ctrl-C), then paste it (Ctrl-V) into a reply here as TEXT not screenshots.  Post that, do the same for the Upstream and Network log.  You'll get an error message when you post the Network log, just click on "post" a second time.
