Constant Dropouts Hub 3.0 Modem Mode for a minute or so and then reconnects

Had the same issue a few years ago and engineer cam and fixed something and has been fine until recently but at different points in the day hard wired connection loses connection for a couple of minutes and then connects again. Once it starts it tends to keep doing it. Rebooting router tends to help for at least a while.

Any help gratefully received. Have tried to set up a Broadband Quality Monitor but this is 100% red. Had this working previously.

  • You have a terrible connection, a technician’s visit is probably required to rectify. 

    Check with Area faults on 0800 561 0061 If you have a VM landline 150 this goes down to post code level. You could also try the web page status, but this is not recommended as it only covers issues that affect a very large number of customers.

    VM will not dispatch any technicians while an area fault exists.

    If no area faults found:

    The primary place to report faults or for service requests is Customer Services on 0345 454 1111/150 if you have a VM landline or wait two or three days for a VM staff member to get to your post. This board is not a fault reporting system.
