Updating device drivers with ubuntu
3G/mobile broadband adapters look quite similar to wireless (wifi) adapters, so if you think you have a USB wireless adapter, double-check that it is not actually a 3G adapter.
To check if your USB wireless adapter was recognized: If your wireless adapter was not recognized, it might not be working properly or the correct drivers may not be installed for it.
New users tend to favor immediate functionality over long-term ideological gains, so if you have an proprietary graphics or wireless card, you may want to install the proprietary drivers for it.
Note: if you're installing a wireless driver, you will need some other kind of internet connection to do this—wired connection, USB tethering, etc.
If hardware isn’t working on Windows, there’s usually a driver to make it work.
Unless you have an ancient device that only works with older versions of Windows, the manufacturer has done the work of making it work with Windows.
You'll then see that proprietary drivers are not in use.
Under Vista (my previous OS), the signal strength had been much higher (more like 50% ). When I ran a speed test I found my connection was only 700kbps, however the same speed test under Vista gives me my full 10mbps of bandwidth.Wireless adapters that plug into a USB port on your computer are less common.They can plug directly into a USB port, or may be connected by a USB cable.Even though the wireless adapter is connected to the computer, it may not have been recognized as a network device by the computer.In this step, you will check whether the device was recognized properly.
Hi just go to 'System Settings' and under 'Hardware' section click on 'Additional Drivers'.
