Query: Terrible products

I bought the 2502 powerline ethernet connector and the 2521 powerline access point. I was adding them to a network which is using two NetGear XE-102 powerline connectors. The Netgear products installed instantly without any software (except to add encryption, if you want). After several hours neither Siemens/SpeedStream product worked. Passwords are required for each device. You have to match to the default settings on the access point for all your devices. Forget it. It's a nice idea to have a powerline access point and I hope Netgear develops one. The instruction booklets are cryptic and useless.
