I also experience this problem, i live in rural area with NO broadband so I do a lot of torrenting at the public library. many times a d/l will stop at 99.x % and nothing works to make it finish. HOWEVER if i go to another location such as a friends house or use my cell phone as a hotspot these unfinished files WILL finish almost immediately.
what gives? is there anything that can be done ti remedy this issue?
also its not always all the files, sometimes 8 of 10 will finish, and other times only 2 of 10 will finish.
