Daily Network Dropout's

I have had daily dropouts for a couple of months now and poor wifi for years.  The wifi is truly awful and coverage is poor in a normal 3 bedroom house that doesn't have thick walls.  The issues I have had recently is dropout's and this is both through Wifi and Ethernet.  Checking the router I get the below (I have removed the MAC address).  I get daily dropouts and sometimes several on one day.  Checked and it says there are no issues either on my line or the local area and I have rebooted the router.  Any help much appreciated.

Re: Daily Network Dropout's

Despite how it may appear from all the "critical" and "warning" messages, there's nothing obviously amiss with the network log.  Can you post up the content of the two tabs titled Downstream and Upstream that you'll find in the same place as the network log?

Re: Daily Network Dropout's

There is nothing showing on the logs as I don't think they cover the time it went down. Next time it happens I will logon to the router and post the logs.

Re: Daily Network Dropout's

What I'm after is the tables of numbers for Downstream and Upstream.  Those show things like power levels, SNR, frequencies, error counts.

Connect to the hub by clicking on this link http://192.168.0.1/  or type the link in to your browser.  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.

Then we can check for any obvious problems with power, noise or error counts.

Re: Daily Network Dropout's

Unfortunately I can't spot anything in the latest data.  Upstream power is at the lower end of the acceptable range, but in theory should be OK.  

I suggest you setup a BQM over at https://www.thinkbroadband.com/broadband/monitoring/quality that might show a little more of what's going on with your VM connection.  Post a LINK to a LIVE, SHARED graph here and we'll see what's happening.  Usually needs to run for 24 hours before we can draw reasonable conclusions, but the live graph will continuously update so you can post the link immediately.

Re: Daily Network Dropout's

Hi @mburke78

 

Thanks for posting on our community forum!

 

The hub is currently showing offline on my side, could you give it a reboot and let me know once done so I can review this please?

Re: Daily Network Dropout's

@Travis_M hi I didn't notice my connection dropping but might of been on a work break.  It is back working now as I'm typing this to you.  These are the readings from the router.
