I have an Envy dv7 laptop with a Ralink RT5390r wifi card with the latest driver updates. I have 110 Mbs internet speed service and when I do a speed test with a cable connection, I reach the 110 Mbs speed but when doing a test with the wireless, I barely reach 30 mbs, plus, occasionally, I experience bumps in connections. I've read on several HP sites and elsewhere of solutions but I've decided I want to replace the card. Unfortunately, I cannot locate the specs for this card nor can I locate a compatible and better replacement. Can someone guide me in the proper direction to help me achieve my objective?
