Hub 5 needs reset constantly

The router needs reset 1/2 times a day as I get an "unable to reach default gateway" error and wifi and internet goes down.

    The hub might not be liking some of your 3rd party devices which VM say they don't support your best option is to get a better router with 1Gb ports and put hub in modem mode.

    I assume "unable to reach default gateway"  comes from a laptop or PC suggesting the computer is unable to reach the Hub at 192.168.0.1 the Gateway IP. It reads like a connectivity problem on the inside of the house not between the VM Hub and the street cabinet.

    When using the 2.5Gb/s port of the Hub 5 make sure to have EEE Disabled.

    if using Wi-Fi make sure in the device manager the WI-Fi adaptor can not be powered off by Windows to save battery & in the process loose connectivity.

      Unfortunately, this happens with all devices. had this same issue 3 months ago and it came back. the issue is due to the power levels going over 6dBmV which causes the Virgin hub to cycle until this stabilises and this prevents any access to the router.

      This has always been disabled. Even if its Wifi or Ethernet this happens. Technician was out yesterday and apparently there is an issue at the exchange as there was some recent work done and the cable to mines was not upgraded/changed when it should have. Appointment for them has been booked for early June but still getting daily drops and requiring router to reset to get this working.

    Those latest stats show the Downstream power to be too high, and there is also "noise" on the line as shown by the PostRS errors.  That is far from fixed IMHO.
