I’ve used a couple of Netgear Powerline adapters and while I generally really like using them I’ve had issues setting the communication security between the units forcing me to do a factory reset on the devices.
The Netgear documentation clear states to hold down the Reset button for 1-second. Page 6 of the XAV2001 manual:
And again on the install guide, “Hold the Reset button for 1-second”.
Well I tried that multiple times without sucess. Finally, on a chat with support they said “Hold down the reset button for 30 seconds.” I thought that was just a standard line but went with it anyways. Imagine my surprise when it actually worked and the devices reset.
