view story

http://forum.xda-developers.com – So I updated to ICS few weeks ago but now i cannot connect to wifi hotspots. I generally use connectify to make my laptop as wifi hotspot, to which my other devices, including phone, connect. On gingerbread, i was able to connect to this laptop wifi, but now i cannot. It shows in the available network but wen i click connect, nothing happens (it doesnt connect), no erro rmessages. (HowTos)
