Hi enybody help before I jump (Joke)

I have an wifi internet radio and it conects to the internet and I can tune
it in to one of the thousands of radio stations from around the world great
no problems.

The problem is trying for it to locate the laptop I am on , on the network
when i use the LOGIK ir100 to scan for computers the result is -- NO
COMPUTERS FOUND-- i am using windows VISTA home primium and have selected a
folder to share, this is on a private network, I have entered the correct key
for the internet . An icon is shown on the network for the item but with a ?
inside it. I have the following for the unit.

The LOGIK 1r100 wifi internet radio just will not recognise my laptop.

Any help will be much appreciated from a UK over 50 years of age thank you.
