Can't see mobile wireless device on wireless network

I just upgraded from Vista Home Premium to Ultimate and now I can't se
my Sony W995 mobile phone listed under Network. I used to be able t
browse its folders and copy files to my laptop

The phone does not appear in the list of wireless devices when I try t
add one. The phone is definitely connected to my wireless route
because it can access the Internet through its wifi connection

Has anyone got any ideas? The phone has "Network Sharing" switched o
which should allow me to access it wirelessly
