Just installed the Hub4 that arrived today and it all auto activated just plugging it in. Turned on modem mode from my phone after connecting to the hub's wifi (sod disconnecting my switch and faffing with cables lol) and got back and running within 20 mins or so.
Getting 900-950 down and 40-50 up on a peak weekday evening so not bad at all. Shame the uploads are so low still but I guess hopefully they increase this once the whole country is FTTP which VM are planning on doing over the next 2 years I heard.
The Hub 4 does look and feel cheap and inferior to the Hub 3 though it has to be said. Not that it matters as it's in modem mode and sat behind a sofa. The LED ring is quite bright however which is slightly annoying.
Edit*
nice now that STEAM can download a big game in 10 mins
