It regularly happens that the two adapters are disconnected from each other suddenly and completely random. I find it necessary to reset one of the housings using this button in the best case
In the worst case, I have to disconnect the two adapters and the I reconnect to finally deign to reconnect to each other. This is especially fun to have to do this when one of the adapters is accessible only moving a piece of furniture (CPL for connecting the PC upstairs to my box located below the TV).
This problem is really annoying because my PC (and my PS3, incidentally) upstairs are likely to be disconnected from the Net at any time, which is very nice!
In short, this is for me very disappointing.
