Ok I have a pc and a server at home and a NAS box. The pc is an HP i7 with Windows Home Premium 64 bit and the NAS box is a Buffalo LX-WSL2B6.
I tried to copy a very large file to my NAS box from my pc and I had to kill the process. Since then writing to the NAS box is very slow from my pc - speeds of around 40KB per second.
Reading from it is fine. Also writing to it from my server is fine and also running a virtual pc in my pc works fine too. So I'm guessing some network settings have been broke somewhere or something like that?
Also copying from my pc to shares on my server is fine too. Ive rebooted everything, changed network cables and set my NAS back to factory settings.
Any help much appreciated.
