to describe quickly my probleme :
I install last week mcafee personnal firewall , disable window firewall, since then the connection is unstable , i can't download more than one file at a time usually not faster than 15 Kbs the other files just don't connect .....
just befor i install mcafee i did not have any protection for a week and then lime wire was really fast .
On Mcaffe lime wire has full access on internet application , and i also add lime wire in the trusted ip adress but no changes the wall is still on front of the globe .....

can annyone help me boost my connection again ?
