Since changing my VDSL-2 40/10 service hardware setup a few weeks ago the TBB BQM is not working.
Previous setup, ZyXEL VMG1312-B10A in modem/router configuration, one box setup.
New setup, ZyXEL VMG1312-B10A in modem only mode, ZyXEL VMG3925-B10B in router mode, 2 box setup.
Have a static external IP address from my ISP Plusnet.
Have set the appropriate "ping enable" settings on the VMG3925-B10B router as per the previous settings on the VMG1312-B10A when it was in modem/router service.
Funny thing is, after deleting and re-configuring BQM monitor on TBB site it will work for a short period of time, a few hours before reverting to full "red" ping failure again.
Have not posted a query on the TBB site forum as yet.
Any suggestions welcomed.
