Do you know what client it is that your neighbour is using ?
It is not against the 'rules' here for you to mention a 'competitor client' if such is the case.

If he is also using LimeWire then there is the possibility that the problem is with your machine or installation...
If he is using another client, then that opens other arguments...

And, LeeWare has a very basic question re: download performance other than via the Gnutella Network...

Hey ! Hi LeeWare... Long time no talkee !
I bet you meant 'lots' of sources instead of 'lost'
