Sounds as though you have problems with your ISP. I hope you don't use AOL. That's known to cause problems for some people. Nice RED. Except it's a bit sore on the eyes. lol
I don't know why you keep losing your connection. How many files do you share. Some people filter out those that share less than a certain no. So if you share less than that no. you'd never be able to connect with them even though they show in your search results.
If you have people uplding from you then you should receive consistent results.
