BleepingComputer.com: FileZilla/Internet issue!

Hey everybody!

I've been having really weird issues everyweek when I upload a file through FileZilla to our churches FTP server. Everytime I upload a file my internet is connected but I'm unable to access any pages, it says I'm online but when I go to yahoo or any other website it just sits there trying to load...but, after I reset my pc and start the internet back up, everything is fine. It's really weird...anyone know what the problem is?

thanks!
