Bought an external monitor and a stand to run my MacBook in clamshell mode and when I use the internet it is TERRIBLY slow. Anyway to fix this ? Got a mid 2010 MacBook Pro
Are you using ethernet or wireless? If wireless, make sure nothing is blocking the hinge of the MBP. The plastic hinge contains all radios (wifi, bluetooth, etc.) so any obstructions will result in less than optimal performance.
