I'm just flagging this up as we had some one in the other day who and I quote direct from the topic on the TA Fethiye Forum
"When trying to connect my Kindle to the wifi in various restaurants (Bogazici, Address, Mozaik Bahçe, etc) I found that as a foreign national I was asked (on the screen of the Kindle) for my passport number and password".
His wife had a Kindle Fire - same problem in all places. A friend of ours was in today and he had the same situation on his UK mobile but when he tried the password the second time he was connected.
As far as we know most people are connecting straight away but I wondered if anyone can shed any light on this; it hasn't happened in previous years as far as we know...
