Hub 3 VM dg505 TG 2492lg VM It's very hot at the top
The Hub 3 is a current model so VM would not automatically swap that. Did the VM tech say why s/he thought the hub needed changing?
What lights are showing on the front of the hub? Use the link at message #4 above and click on the picture of the Hub 3 to see the options. A solid red light at the bottom indicates the hub is too hot.
Next steps would involve checking the hub's signal levels are in spec but this 'Account - Cable' forum is not the best one to get help with that.
The VM forum team should be able to remotely check your connection and advise if any issues are showing. They should pick up here within a day or two.
