Summary: Before I purchased my internet I had to go surfing for a strong safe signal. Then I puchased the D-Link D-130 and later two DWA-160. It improved my connection immeasurably. Absolutly no drop outs. Later I purchased a 35GB dowloaded game and it would take about 8 hours surfing on someones signal.
