I have an old HP with the Holly-2. That has a 1gbs on board network adapter in it. I upgraded the cpu and ram to max at amd 3080k and 8gb. I just built a computer with a b650 aorus pro ax motherboard with on board 2.5gb link speed and a ryzen 9 7950x 128gb ram. I don't know how to find the link speed on my laptop but its got an i78565u and 32gb. If it's got all that it has to have at least a 1gbs adapter in it. Both newer machines are running win10 and speed test at about 100mbs while the old hp with win 7 can hit around 500. My isp supposedly provides gig speed internet. I'm happy with the 500, but for the life of me I can't figure out why my two newer machines can't get close to that. Any thoughts?
