Yes, you would need to ring them and tell them you want to re-active an old modem but if that's the old superhub 1 then speed will be limited for broadband I think. If you call them and tell them some of your connected devices aren't compatible with the SH3 but work fine on a friends 2AC, they will send you one out foc - they did for me anyway. If they ask what you're connecting, just tell them a freesat box and a games console and it's causing the SH3 to crash.
