1. My internet speed has jumped nearly 30 mb/s. My downloads are extremely fast at @ 2.7 - 2.6 mb down. It wasn't always like this. I pay for 15/5 and a little while I go I used to get max 1.7 mb down.
2. Why does my router (d-link dir 601) slow down my upload speeds, they are usually 500kb up or 5mb/s when connected directly to the modem.
