My ISP service tech found that I am receiving 102 mbps going in and coming out of my modem by am only getting 20 -30 mbps through my PC. We had the cable re-ran due to squirrel damage last year and I've seen my speed run at 70 mbps about a couple of months ago. We did have a few power issues with storms recently but my wife believes it was slow prior to that. It says my LAN card is working properly. I've got an AMD Phenom II X 4 (2.8 GHz) with 6G RAM and 1T space mostly empty. Any suggestions?
