Hi dazgray
If you are using a 3rd party router then the hub3 will display a magenta (red) light to show that it's in modem mode.
If you are in normal router mode and the hub is well ventilated, then if it's hot to the touch then the red light may be a warning of over heating and need replacing. Turn the power switch off on the back of the Hub. Ensure the Hub is upright, in a well-ventilated location, and, if at all possible, out of direct sunlight ( I know it's winter) Then use the power switch to turn the unit back on. The Hub should now operate normally.
If the red light still shows after doing the above, then it does sound like it's overheating or liable to start doing that as it can become a fire hazard and you should pop back here and update the thread so forum staff can then arrange an engineer to visit to swap out the hub.
Regarding the speed. Gig 1 isn't available in all areas (some may be over subscribed) Use the following link to see what speed is available for your postcode (use a different house number)
https://www.virginmedia.com/broadband/gigabit#gig1 (you might need to use incognito mode to get it work since you are an existing customer)
If you are in a Gig1 area then you would be sent out either a hub 4 or a hub 5 (depends on equipment availability) since the hub 3 can't cater for Gig1 speeds.
Have a chat with retentions and negotiate a new deal with them (option 4 thinking of leaving us) when dialing 150 from a VM landline or 0345 454 1111 from any other phone, call around 8am if possible when lines first open and are least busy.
They are generally based in the UK, and have a greater degree of knowledge and flexibility, along with a larger range of discounts than the front line agents
