Actually I think it was the router; it's been playing up a bit today and my XP computer is connected through a different router. (Both my tablets are connected through one, and my XP through another.)

I just want to check the sequence of things if that's OK:

1. Flash kernel with image
2. insmod extra packages
3. Have fun trying to configure PPTP.

PS will try the commands when I get home, let you know if it's any different.
