OK well I am no expert but....

To get any real use from the ipronto you need a WAP (wireless access point). I have a Netgear MR814v2 which seems OK. mine is a router and WAP in one, which when we finally get broadband I can share this net connection with my ipronto's and other PC's, without the need to power up my main computer.

In my case the MR814v2 plugs into my ethernet port on my PC.

Some WAP's do not work with the ipronto so my suggestion as first step is go to your local computer store with your ipronto and see which one works before you buy....
