Can't remember if this has been covered, re: the amount of 1Gig ports ?? Cut & Paste below ...............
Hub 5 -- So what’s new?
It looks very similar to the BT Retail Hub 4, but the biggest difference is that it is a combined VDSL modem and router, which means you must not install a separate Openreach VDSL modem on FTTC installations. It has smart set-up technology, which means you don’t have to run a separate welcome CD when connecting a PC or laptop. The Hub 5 automatically detects that it’s a new installation and guides the end user through the software set-up process. There are also four separate 1 Gigabit Ethernet ports on the back and the next generation of WiFi.
