Funny as we were in a coffee shop the other day.
My friends happily open their iPhone and HTC and was immediately connect to the Wifi at the coffee shop.

As for me, I couldn't.
It asks to 'push a button on wireless station to initiate easy setup process' on the router that I have no access to.

I found this happening on pretty much 9/10 non-protected Wifi networks.

I believe many of you will have noticed this odd limitation of the N900

Is this a bug?

To check:
1. Find a non-protected Wifi with the Wi-Fi Protected Setup compliant (easy at coffee shops)
2. Use your laptop or a phone with Wifi connectivity and connect to it.

They (the laptop and the other phone) should connect fine, but N900 you will never be able to connect to it.
