* The density of BTWiFi hotspots means that one can sometimes reach two or three possible routers, all connected to the same captive portal. This can sometimes (rarely) lead to unexpected effects, if disconnected from one network and connected to another one that shares the same portal; the portal views us as logged in, but our traffic remains blocked. | * The density of BTWiFi hotspots means that one can sometimes reach two or three possible routers, all connected to the same captive portal.

- | * In particular, this has been noted when switching from BtWiFi to BTWiFi-with-Fon, and it is imagined that they share a web portal but not a DHCP server. This caused problems for the perl client (which presumes by the absence of a redirect that we are connected) but not for the python client, which tests whether it is connected by verifying the content of an HTTP GET request. Of course, it creates a dependency on the availability of a remote server and I don't much like the script's default of fetching "www.yahoo.co.jp"; we don't need an entire HTML page to confirm that we are online, but we do need to keep the check in some form. | + | * In particular, this has been noted when switching from BtWiFi to BTWiFi-with-Fon, and it is imagined that they share a web portal but not a DHCP server.
