well, if it's 802.11b/g/n then no, it's no good for roaming as it will have a very limited range. I don't see how you were able to connect to it without using some kind of wireless networking adaptor, to connect to wireless networks you need a wireless reciever.. I'm not sure if there is a misunderstanding or technology is different in your country, but data cards generally run of mobile/celular networks so if you are on the move then this by far beats WLAN 802.11b/g/n range

that's paranoia, 802.11x wireless (or Wifi as its commonly known) does not have a great range. Chances are you have a neighbour who doesn't understand how to configure their router to be secure.
