Im at witt's end.

I used to be able to push files from my desktop to the NAS via wifi.

Now the files upload incompletely (1.5 out of a 5gb file) the upload goes WAAAAAY too fast (more than 70Mb/s) and at the end of the incomplete transfer I get a msg that the file already exist and do I want to overwrite the file (hitting yes does the same thing)


Any ideas? I used to be able to do this easily. Now I have to sneaker net the drive from desktop to router. I can READ files ok from ANY device, its just transferring them from PC to NAS drive
