I have a PowerBook g4 running 10.5.8 For several months been noticing really slow internet, even though at home I have DSL at 8 Mbps and work we have cable at 20 Mbps. Flash and any type of video is unwatchable. I ran speed tests today from various sites, and noticed my speed clocking in at around 4 Mbps (work; 20 Mbps). So we called Charter, got them out there, everything checked out fine. He said he ran speed tests and it was showing OVER 20 Mbps. Sure enough, I checked a couple of iMacs that we have, as well as a cheap-o Compaq laptop, cheap-o HP laptop and a high-end Dell desktop. Every single one of them showing 20 Mbps or over! I am really aggravated! I am starting to think my troubles didn't start until I had a tech upgrade my laptop to 10.5.8 Anybody have any ideas for me?
