I have PM's pablob as he said his FPL is working fine with Teksavvy (which makes me feel a little better.
Teksavvy suggested putting the ATA in front of my router (but it has never been). My ATA only has one ethernet connection so this is not possible. But if I need to get a new one I will. Just very confused and frustrated.
Thanks for the suggestions and help all, it is appreciated.
