dear sifu's.
recently i encountered this wifi issue while overseas. since i have no data roaming plan, i solely rely on wifi to get connected. my problem are as follows.
1. connected to hotel wifi, then when i come back from sight seeing, cannot connect. always stuck at "Obtaining IP address...". Restart phone, forget network doesnt help. What worked was the hotel had a power outage which restarted the router.
Obviously it's nothing to do with your phone. Probably the router is congested, dhcp full, lease time not refreshed etc.

2. same as above but happened at a cafe. this time was "connected" but nothing loads (facebook etc. etc.)
why does this happen? i know its simple as restart router, but sometimes, i dun have control over that..
additional note: my wife's note 2 (which was my old phone b4 switchin to z1) could connect properly without any issues...

I think you're just unlucky. Do you still have any problems now?
