Hi, I am currently using my 5800XM as a 3g modem on my laptop since I get 2gb for free every month from my provider. If I am simply "browsing" the internet, the connection will stay on all day if I let it but, if I start to download something and the speed goes over 150kb/s the connection will die and I will have to re-connect.
below is how I am currently set up:
PC: Windows Vista SP2
5800XM: v 52.0.007.c01.01
Phone mode: PC Suite
Dial up connection (created with vista NOT using Ovi Suite,
Phone Number *99#
