I recently bought a USB wifi adapter for my new desktop computer. It's a D-link DWA-160 A2. From the start it didn't want to work at all, but after unplugging and then plugging it back in, it seems to work.
However, my browsing is painfully slow. NetworkManager reports the connection to be at around 78-85% signal strength, which seems perfectly acceptable.
Is there anything I can do to make it faster? I'm dual booting with Windows 7, where it seems to work fine, so I'm guessing that the problem occurs because of crappy drivers.
