[olpc-help] XO freezes in One Building

[Anonymous]

Hello,
I've been having success using applications and getting WiFi access in various venues like coffee shops (TMobile and other networks). One building in which I cannot get the wireless connection made is my own place of work. In certain rooms or areas the XO freezes -- sometimes without working at all after powering up, and sometimes freezing after some period of use. In no location in the building can I complete the wireless connection. This is a city library. We use Radio Frequency ID technology for materials check-out and security--could this be the possible reason? I have checked and our wireless network is not WPA or WPA2. I appreciate your hypotheses!
