When I try to connect to wifi, there are no options on the wifi screen. It just says "searching for wifi networks" and it never shows anything, even if I try to turn it on and then back off. I've tried restarting my phone and the router. When I restart my phone, the wifi turns off and on constantly, connecting to the wifi, then turning off again. It's not a problem with the router because it's working for everything else.
Try resetting your phone to factory defaults, and if that does not work it could be a hardware problem.
Welcome to Android Central! Which phone do you have? Does this happen with other wi-fi networks as well (like in your local coffee shop or library)?
I'm using an lg g4. i haven't gotten the chance to check other wifi areas but I'll get back to you on it.
is there any way of saving my data without erasing it completely when doing the factory reset?
A factory reset is deleting your data - that's what it's for. So no, you can't delete all your data without deleting all your data. (Normally a wifi failure is a hardware problem - which a factory reset doesn't fix.)
I suspect androidguest1 is asking for good backup methods so that everything can be restored quickly and easily after the factory reset. Check out Rukbat's excellent guide: http://forums.androidcentral.com/amb...id-device.html
