Got the phone yesterday. (Prepaid certified preowned.) Tried to put in the wifi password, which the phone rejected as incorrect. Activated it over iTunes. I called to have my existing number assigned to the new phone and I tried asking about this, but the guy I was talking to didn't understand. (Language barrier maybe. Idk. He told me to turn off wifi to use 3G so I gave up.) Knowing this is a well known iOS issue, I updated to 8.3 for the possible fix. Still not connecting UNLESS it's next to the router. I did get it to connect that way but lost the connection once I moved away from the router. My droid tablet and computer consistently stay connected. My old iPhone 4 (which I was replacing) connects but the speaker is broken and I can't hear calls. (It drops frequently, but reconnects eventually.)
After doing a ton of research I've discovered that this is really not uncommon. I've tried resetting the network, updating router firmware, checking and changing wifi settings on the router, resetting the router, almost every suggestion I've read but nothing has worked. I'm not putting it in the freezer. I'm very worried that if I send it back for another one, I'll have the same exact issue. Is it even worth trying to do a factory reset, since it came to me with this problem, or am I stuck either sending it back or having no wifi?
