Just came across to help to on this.
You can purchase a cheap wireless router (HUB) from a place called
Golden Plaza in Shamshui Po, by taking the MTR.
You should be able to find everything to do with computers and accessories there very cheap.
Most Routers will have instructions by default its very simple to set it up yourself.
But first do register your broadband service, you might like to check most of the services first whilst you are about in Shamshuipo, as you will find alot of the broadband promotions outside the building (at the sidewalk).
Find a service which you think is best for your area, they should be able to tell you after making a call to check free for you. Now is by far the most expensive of them all, I personally prefer Hutchinson 10M, which is very stable and fast. (I get this plan for HK$128 per month).
I hope this will help you decide on the service and then go get a wireless router too
