Networking what a surprise!

I'm using a Netgear 632 Modem/Router, although a single port router you can
connect 2 computers, one via Usb and the other via rj45 socket this works
fine, so I purchased 2 Fla85 Ethernet over powerline homeplug adapters so I
could connect second computer upstairs, having initially set up and worked
fine, I'm getting extremely slow internet speeds upstairs!

I can ping each computer and get average speeds of 1-5ms, fine! When I ping
router from upstairs
I ocassionally get lost packets although the powerpacket utility for the
homeplugs tell me I'm getting speeds between 10-20Mbps.

Both computers running zonealarm and setup fine,
router set to allow second computer too.

Any ideas?
