I have a Vaio FitFlip Laptop and I dual booted it with Windows and Ubuntu.
The problem is, when I'm in another room where the wireless signal is not really strong, the Internet connection goes really slow and disconnects automatically a lot and asks for the wireless password.
When I'm in the same room where the wireless router's signal is stronger, it doesn't seem to have that problem.
This doesn't happen when I'm using Windows, so I think it is related to Ubuntu.
What can I do to fix this?
