Iphone 5s loosing Wi-Fi connection

I'm getting fed up of my iPhone 5s loosing Wi-Fi signal, it will go back to 4g or 3G or gprs it is really getting to me. All other devices and phones in house hold stay connected constantly. The iPhone has to prat about. Any fixes or ideas please.

Fed up

  • Why is my iphone 5 loosing so much battery? So I have already had to get a new iphone 5 through my warranty for a broken battery and now this one is doing the same… I could leave the phone locked for 10 minutes and have all apps closed and I'll get back and atleast 10% battery would be gone when I use it again How can I stop this from happening? No the phone has never even been anywhere near water not even near a drink
  • Since iOS 6 update, my Verizon iPhone 4 service keeps dropping and loosing signal? Since I updated my iPhone 4 (Verizon) to iOS 6, my cell signal is constantly dropping or searching. Doing so also kills my battery life. Any body have the same problem? What can I do to fix this?
  • Should my mechanical wrist watch be loosing time? I bought a very nice $5000 montblanc wristwatch a week ago and I've synced it almost perfectly to the iPhone watch and I've noticed that my wrist watch tends to run ahead about 50 seconds every day. Is this normal?
  • Loosing music on iphone when syncing? So I got a new laptop and my itunes has mucked up and only transferred my purchased songs. I have all my music still on my ipod but if I plug this in and sync it with my new laptop (to put on new songs I've just downloaded from CD's) will I loose the music already on the ipod?
