Upgrade M300 to M600 Speed slow

[abhachu65]

I had an upgrade from M300 (hub3) to M600 (hub4).

Since the upgrade the speed has been very slow.

Called Virgin support several times. Had a technician who swapped the hub.

Still the same issue. Wired speed 179mbs - 280MBS

Wireless - 220mbs -  280mbs

Any help please

Any help on this please.

The new M600 is running slower then the M300.

Hi abhachu65,

Welcome to the community and thank you for posting.

I am very sorry to hear you are experiencing issues with the service. 

Unfortunately I have been unable to locate your account via the community details to check things from our side but if you could access your Hubs advanced settings and post your network logs, we would be happy to take a look. Information on how to do this can be found here.

You can also run a BQM (Broadband quality monitor) and share your link to this thread 🙂 

Thanks
