My iPhone 4 won't connect to Wi-Fi unless I'm standing next to a router?
I just bought an iPhone 4 (ios 6) from a guy and when I got it, everything works perfectly fine except for the Wi-Fi. My iphone won't connect to Wi-Fi unless I'm standing next to my wireless router (located in the living room) and when I walk to my room, I lose signal and then the internet won't work anymore. I have an ipod touch too, and the Wi-Fi works just fine (its 4 bars when i go to my room ) my laptops work fine too. It's just my iphone that doesn't work. How can I fix it? I can't get the iphone replaced because I don't have a warranty and I didn't buy it from the Apple store.
What I'm thinking is wrong with it is it's internal antenna is messed up. Possibly trying making a call? If the call works successfully with very little problem then I doubt it's the antenna. Other than that, I'm not to sure, sorry.
You got robbed
Depending on what the problem is:
If he had taken apart the iPhone he would've not re-plugged in the antennae inside the iPhone
The only reason I could see him taking it apart is to replace a broken screen
Other possibility
Could be a software issue. I would to try this first, look up how to enter DFU (direct firmware upgrade) mode and update in iTunes to re-flash the phone software and that may fix the problem
--- Edit ---
The phone and Wi-Fi antennae are separate
- What's the difference between a cheap router and a good router? Just wanted to know the difference between a cheap router and an expensive router, I know that is a very broad question, I'm just a bit confused on how a router works. Does it increase my Internet speed on multiple devices? I get 50Mb per second, Well at least that's what I pay for. I have a PS3 two iPhones and a tablet, as well as a desktop PC that is wireless. Can anyone recommend an excellent router under $150

- My Wi-Fi won't connect unless I'm right next to the router on my iPhone 6? My Wi-Fi has worked fine on my phone ever since I got it. But lately, it's only been working on my phone right next to the router! Which is weird because it's working for everyone else. It's something wrong with my phone. I'm not sure what it is. Can someone please help me?
