I've tried the following:

Rebooting the phone several times
Restarting the router
Changing from DHCP to Static IP
Turning off the new open network notification
Clearing data from Google Play store
Disabled wifi power save with *#0011#

The wifi will work for a short while and then it won't work. It was working fine before. What should I do?
It's possible that your router has some hosed addressing tables - if it has a reset button, not a bad idea to try that.

I've seen issues like this where one handset is singled out a network - doesn't matter make or model, or even Android or iDevice.

Also, a good idea (on your working phone) to download and try Wifi Analyzer, it's free. If you're sharing a channel with a neighbor, it will show that and you can correct that at your router, the problem could be radio collisions.

And for best results, never use the default router name. I've been in neighborhoods where I've seen 5 different routers from 5 different homes all sharing the same channel and network name. Those people are all getting lousy network service without knowing why.

If it's not that, then it's your phone.
