I've a blackberry that I connect to the internet through barry application, can this connection be shared somehow? I use a old laptop that don't have a build in wifi. I can't use a wifi usb adapter as there aren't support for netgear WNA3100 device.
have you tried to get the wifi usb adapter to work with ndiswraper? most easy should be to use ndisgtk.
with my android phone I can connect to my wireless and than tether over usb. this article claims to describe how to do it with blackbarry, but I can not try it. it is a old post and most of the links are dead, but the berry4all site is still up.
