intermittent disconnect of internet

[Jayp13]

We are facing a intermittent disconnect of a internet. This is random and momentary. I have followed help guidance provided on website which includes - Restart of hub, Reset of Hub. Still the issue persist. After checking the router status- Network Log it shows following "critical" error whenever the momentary internet drop is noticed.

What could be the reason to for slow speed and intermittent internet disconnect?

Your Upstream power is on the low side, but still in the range of 34 to 51, so could be brought up a bit.

Do all the wired connections drop as well, or is it just wifi ?

[Jayp13]

Yes, it happens across all the devices.

Set up a BQM and post the graph after 24 Hrs to allow it to populate.   www.thinkbroadband.com/ping

You will still need a VM technician to increase the Upstream power levels.  If you wait here a day or two a VM Mod will pick this up.

above is BQM for the last 24 hours.
