IDM is a good download manager ,
how ever it happens some times im browsers like Chrome , Opera ,
that some times , downloads fail to be overtaken by IDM .

you can try this .

restart IDM .
click Downloads > Options > General > Check the Advanced Browser Integration .
and now select the browsers for which you want IDM to take over the downloads .

if it still doesnt ,
again go to the Options menu , and click on Custom keys to prevent or Force downloading with IDM .
check the second option and define the key which you would like to use to force downloading with IDM.
follow the simple instructions and that should be all .
it should work now .

and as for increasing D/L speeds ,
well IDM itself is a good manager and accelerator , and you wont get speeds greater than what you pay for in your bandwith .
how ever you can still try this tool ,
IDM Optimizer

it would optimize the IDM settings , so that you always get the max performance .

try and see ....
