I have the same issue, my BT has not started and all seed is 0% suddenly since last 2 weeks. Also, I haven't changed any configuration of my airstation as well. I wonder if anything i can do to fix it as the bittorrent feature is not working anymore.
My version is
WZR-HP-G300NH Ver.1.79 (R1.03/B1.07)
By the way, is there any apps which can help us to upload the seed remotely through ipad or android phone?
Thanks a lot
Ken
