I'm not exactly sure who is my ISP, but if you give some examples of it i'm sure i can tell you. All I know is that I use an Axesstell wireless modem in my house. I got frostwire from the frostwire website and to my knowledge I have not installed or updated anything circa the time it stopped connecting. Is Limewire or any other Gnutell networks having the same probs? If so, it probably is the ISP.
