I have the Samsung 4G and it is working fine from desktop using a USB network adapter. My HP laptop with a broadcom network adapter is another story. It connects but takes forever then comes back with message that it has "limited connectivity" and basically doesn't let me access internet explorer. When I go into the admin it shows I have two devices but the 2nd really isn't functional. Have tried reinstalling the network adapter so I could default something I may have messed with but no luck.
