FON ownership a waste of time - for me anyway.
Hmmm, I have THREE of the basic FON Access Points around my home in HK, one is troublesome in that it requires power-up and then pull the DC power cable & re-insert if the unit is ever to connect back to one of my many routers & on to Internet.
In my travels - I have never found ANY FON access points to connect to - and I have THREE good working reasons as to why I should - if I can ever find an access point outside of my flat.
Also, I've never had any "traveller" access via my FON Wi-Fi points - the only access has been the occasional very local - read, in my building complex - using the "Open Channels that my FON's offer for free from their additional high gain antennas.
The only reason I keep them active is to provide my 'pina maid with Wi-Fi signals in her room.....
Luckily, when I travel, I usually get "free" Wi-Fi from the hotels I stay at; the FON units - which cost me HK$48 or so (years ago) at a promotional time - are rather a waste of time!
