so i have comcast. 52meg download / 10 upload. Youtube , netflix, etc still takes forever to load. AT 52 MEG. Why? I recently upgraded my ram to 4gb. Installed a brand new hard drive bc my old one was going. So it should have nothing to do with my computer. & comcast says everything is good on there end. They ran all new lines, got a brand new router / modem from comcast. & still webpages take forever to load and youtube / netflix lag. Help !
