My iPhone 4s doesn't connect to my Wi-Fi router at home, but it does connect to any other Wi-Fi router. When I attempt to connect to my Wi-Fi, a webpage pops up which asks me to log in (like it would if i were using public Wi-Fi). These webpages vary, there's: airport.us, thinkdifferent.us, appleiphonecell.com, and captive.apple.com. I have reset my network settings, and my entire iPhone, but the problem remains the same. I'm not currently using a sim card, so i was wondering if that may be causing the problem. The phone worked absolutely fine until about three weeks ago, so i unplugged my Wi-Fi router, and the phone started to work again. About a week after, the Wi-Fi problem happened again, and now unplugging the Wi-Fi router isn't any help. I use the Wi-Fi at school, at friends houses, at restaurants, and they all work, but my Wi-Fi at home does not. I can choose to use my Wi-Fi without having access to the internet, which when i do, I still get notifications for iMessage, Messenger (app), snapchat (app), instagram (app) and twitter (app). I was also able to use FaceTime, but since reseting my entire phone, I can't. Other people can use my Wi-Fi at home freely.
