Troubleshooting NETGEAR's Powerline Products

I'm using a pair of XAV2001s and a pair of XAV101s. They work fine as lon as there are only 2 adapters on the network. It doesn't matter which two -- both sets work. But as soon as I add plug a 2nd aparter into my router (this would be the 3rd one on the network) the entire network shuts down. I also start getting IP address conflict alerts from the computer connected to the first pair (it doesn't matter which model is connected first). I tried assigning static IP addresses to each adapter and to the computer complaining of IP conflicts and that got rid of the IP conflict messages but didn't fix the network shutdown problem. I used the config utility to set the same security password on each adapter but that didn't change anything. What should I try next?

yup, i think i have the same problem but with XET1001s...do you find it takes down your entire network as well? I'm hoping its just the ethernet cabling which needs to be replaced or i can move the powerline to a better (cleaner) power source
