Home internet problem: paying for 30Mbps service. Technician plugs his laptop into my modem, speed tests at 29. My computer (testing both IE and Firefox) speed tests at 9.5Mbps. Malware bytes/Spybot/Superantispyware reports my comp is clean. I'm using the same connection, modem, cables, etc. as the tech, just my desktop is different. Not going through a router - connected directly to the modem.
Tried manually setting network card speed to 10 or 100 to see if one of those settings helps. No improvement.
Tried changing the default packet size to optimize the connection using http://www.speedguid...t/downloads.php - no improvement.
