IPhone won't connect to my wifi router, but my laptop is connected
So I noticed my Iphone 4s randomly lost its wifi connection to my home Xfinity router. There was no updates done or anything changed, it just cut out. Thinking my IPhone 4s has been pretty hit or miss recently I thought it was just one more thing wrong. I tried all the tricks of restarting with airplane mode, restarting the router, rebooting the phone, you name it. I checked my Itouch which has never given me any issues also couldn't connect to wifi. I thought maybe its the router. I checked my asus laptop which has perfect internet connection. So its not like my router is incapable of putting out an internet signal since I can use my laptop and my mom can use her nook. I reset the password to the router and rebooted both iphone and ipod and they both connected! yes! but that only lasted for maybe an hour. I'm currently back to a frustrating square 1. Now when I type into my Iphone the password it takes a few seconds to load, then the window pops up again for the password as if I never entered it to begin with. What on earth do I do?
iPhone 4S, iOS 8.3
