I installed one for my niece. I can't remember all the details. but it was a nightmare to set up. The "reset and start again" routine was the main one we used.
I have a suspicion (can't remember now, and wouldn't mess with it since it's working OK) that part of the secret was NOT pressing the "automated setup" button.
The medium-term plan is to run a long Cat5 cable with a wireless access point on the end of it.
