I'm trying to share my 3G data connection via WiFi hotspot. I have an open Hotspot running on my phone(Xperia Neo V - MT11i - Android 2.3.4). But I cannot connect to it from my Ubuntu system. Here is the syslog while I try to connect to it -

Why is direct probe to 5c:b5:24:2f:d1:2f timed out? Any idea?
