I recently upgraded to fiber optic internet (30 mbps) and found that it's not as fast as I expected through a router. However, when I'm using a direct connection the speed is crazy fast (30-33mbps). But when I use a router (some old D-Link router I bought 5-6 years ago) I get only 4-6 mbps
. What is going on and how can I improve internet speed over a router?
