Frustrating problem ... hanging in network...

I hope someone can help me. I configured a wireless network a couple
of days ago. Or I tried to. Now BNR hangs anytime I try to import an
nzb file. The network isn't reliable (sometimes it comes up, sometimes
it doesn't) and I've fooled with the settings (sharing connections,
etc.). If I show all my networks, it shows several connections (not
users) I don't think I need or I don't know what they do. 

But the question is why does BNR2 hang now? How can I fix this
