Trouble shooting slow network speeds on NV

mdgm, Does the fact that I bought it in 2006 explain the wildly inconsistent results? I can understand how it could result in slower overall speeds. The laptop was inconsistent too, but also much faster. I'd like to optimize what I have, not start over. This is for a home setup and I don't need the fastest. Last year, with your help, I upgraded all the drives, got a fresh start and it has been working fine for most of my purposes. However, I do get stutter on some videos and the back up take forever. It was the backup speeds that got me to acquire the gigabit NIC along with the newest Actiontec. Any suggestions besides the beta? I'm interested in it, but would rather wait for it to be cleaned up.
