Help WiFi and Battery issues

I have a brand new Galaxy S4 and have been having some serious issues


WiFi -

I've googled around and people seem to be having WiFi issues but only with DLINK routers, my issue is kind of different. I don't have a DLINK router, i have a brand new Vodafone router. The router is in my sitting room and when I'm in that room the WiFi is fine but when i'm upstairs in my room etc the WiFi signal drops a lot and it disconnects and reconnects almost every 5 minutes.

So far the fix has been to turn off WiFi power saving mode but when I do that everytime after a while when I try to use Google Play Store to download something I get a 491 errror. (UPDATE: The google play error is still there when using wifi power saving mode or not)
I've tried changing my encryption cipher in my router away from AES but again no luck. What can I do?

Battery -

Only got the phone yesterday wasn't focusing much on battery life but went to bed last night charged it, woke up used the phone for around 2 hours and was at 49%. I then followed every "tip" on the net turned off nearly ever feature put on power saving mode and the phone lasted from 1pm - 11pm and was at 5%

Anyone any thoughts?
 
Your wifi signal from your router probably isn't aimed properly or you should get some sort of wifi signal enhancer. I doubt it's the phone.

I keep mobile data off unless I'm away from wifi. Make sure you get your screen brightness set right as well. Another tip is to go into your apps and check each of their settings. Set sync, notifications, etc to what you like manually. I can get a couple days usage.

I had this same issue, except it happened with my WiFi all the time. I have a Cisco/Linksys router. I had gotten to the point that I was ready to take the phone back. It wouldn't hold a WiFi signal and the battery life sucked. Knowing that the first thing that they would do at the store was to hard reset the unit, I did it myself. Both issues went away. WiFi is now rock solid and the battery lasts all day and then some.

**Edit - BTW, the phone was only about three days old when I did the hard reset.

Your mileage may vary...
