BT download problem

kp3004

I can download files using flashget and the speed is pretty fast (above 100 k/s)
but when I try to download files using BitComet, it keeps saying that it is connecting for a long time
I have attached my computer screen so that it is easier to understand
Do I need to change the setting or anything?
can someone help me out?

is it because i am using networking?
if i use the computer with the router, it won't give me any problems
but when i use the computer with the adapter to download the same files, i can't even connect to a seed or peer
does it mean i have to change the setting of bitcomet?
